Increase in agricultural productivity yields is strongly influenced by climate change. Extreme climate change has resulted in crop failure due to land drought and flooding. The existence of this incident provides an opportunity to decrease the welfare of farmers, especially plantation farmers in Indonesia. The purpose of this study was to determine the effect of temperature on the welfare of plantation farmers in Indonesia. The data used in this study was sourced from the 2018 National Socio-Economic Survey (SUSENAS) data, with a total of 66,754 households in Indonesia. The analytical method used is Ordinary Least Square (OLS). The results of this study indicate that an increase in temperature causes drought, and has an impact on decreasing agricultural productivity. The decrease in the production of agricultural products certainly reduces the income of farmers, which results in a decrease in the level of welfare of farmers. Government policies in terms of climate engineering are needed, as well as assistance programs for farmers to maintain the welfare of farmers.</p> Faradiba Faradiba ##submission.copyrightStatement## https://journalajahr.com/index.php/AJAHR/article/view/176 Wed, 08 Jun 2022 00:00:00 +0000 Bioactivity of Leaf Extract of Phyllantus amarus against Fungal Pathogens Associated with Sweet Orange Rot Disease https://journalajahr.com/index.php/AJAHR/article/view/178 <p>This study was carried out to determine disease incidence and control of fungal pathogens associated with rot of sweet orange using <em>Phyllantus amarus</em> leaf extract. Forty sweet oranges (<em>Citrus sinensis</em> var. Valencia) were collected from the markets and taken to the laboratory. Isolation and identification of the fungi were carried out using standard procedures and the efficacy of the leaf extracts of <em>Phyllantus amarus </em>was determined on the isolated fungi. The result of this study showed that four pathogens (<em>Aspergillus niger, Aspergillus flavus, Penicillum expansum </em>and <em>Rhizopus stolonifer</em>) were identified to be associated with the rot. Rot incidence was upto of 35%. Pathogenicity confirmed the characteristic features similar to the original diseased samples. The effect of the leaf extract of <em>Phyllantus amarus </em>on the isolated fungi shows that the rate of inhibition increases with increase in concentration of the <em>P. amarus</em> extract, The <em>P. amarus</em> extract was effective against<em> A. flavus</em> had the highest zone of inhibition (10.667). The inhibition zone was lesser for <em>R. stolonifer</em> among the pathogens (8.333). Sweet orange should be consumed after harvest or can be stored in refrigerator for period of 1=2 weeks. The fruit should be discarded if&nbsp; any alteration in color or taste of the fruit is noticed as this can be hazardous to human health.&nbsp;&nbsp;&nbsp;</p> C. S. Yusuf, N. N. Zakawa, D. Timon, T.

It is terrible that we do not seem embarrassed to admit this, even when we are just beginning this practise. It is true that there has never been a complete standardisation of this agricultural certification. Herbs are a good option during this transitional time. It is imperative that you proceed with extreme caution if you plan to engage in agriculture. The present study deals with the problems and prospects in cultivation of Medicinal Plants. The study was conducted in Nagaur district of Rajasthan. A sample study of 11 villages out of ten tehsils of Nagaur district has been done. By selecting 11 sample villages from different tehsils of Nagaur district as primary sources, an attempt has been made to collect data and information and analyse various aspects of problems related to the cultivation of medicinal plants in the area.&nbsp; In the past years, the surprising changes in the general cropping pattern and the facts related to it have been studied and various dimensions of cultivation of medicinal plants have been studied considering tehsil wise level as the regional base unit. The problem of saline water, lack of surface water resources and problems in propagation of medicinal plants are the major problems faced by the farmers in the study area.</p> Shankar Lal Meghwal ##submission.copyrightStatement## https://journalajahr.com/index.php/AJAHR/article/view/182 Tue, 26 Jul 2022 00:00:00 +0000 Improving Physic Nut (Jatropha curcas) – a Bio-fuel and Multipurpose Crop Production in Sub-Saharan Africa through Appropriate Nursery Media https://journalajahr.com/index.php/AJAHR/article/view/183 <p>Physic nut <em>(Jatropha curcas)</em> is a bio-fuel and multipurpose crop that can be used to produce biodiesel, biogas and latex. The toxic substances – curcin and diterpenoids in raw <em>Jatropha</em> leaves and seeds can scare grazing animals away and this suggests the possibility of using the plant as live fence to curb cattle menace which is one of the major constraints facing crop production in Sub-Saharan Africa especially in Nigeria. Despite its nutritive, medicinal and economic values, <em>Jatropha</em> is one of the most neglected crops in Nigeria and in sub-Sahara Africa at large. There is often loss of vigour of <em>Jatropha</em> seedlings due to high seed oil content which results in rancidity and weak seedling growth. An experiment was conducted at Enugu State Polytechnic, Iwollo, Enugu state, Nigeria to determine the appropriate nursery media towards improving the production of <em>Jatropha curcas</em> in sub-Saharan Africa. Four nursery media viz: 3:2:1; 1:2:1; 0:0:1 and; 1:0:0 of top soil, organic manure and river sand respectively, were evaluated. The experiment was laid out in Completely Randomized Design (CRD) with three replications. Data on emergence percentage, seedling height, number of leaves per seedling and seedling girth were collected and analyzed using Analysis of variance (ANOVA) for CRD. The treatment means with significant differences were separated using least significant difference at 0.05 probability level. The results showed that there was no significant difference (p&gt;0.05) among the treatments in emergence percentage of <em>Jatropha curcas</em>. However, there were significant differences (p&lt;0.05) among the treatments in seedling height and stem girth with the highest values obtained in 1:2:1 of top soil, poultry droppings and river sand, respectively and the least in 0:0:1 of top soil, poultry droppings and river sand, respectively. It could be concluded that the use of 1:2:1 of top soil, organic manure and river sand, respectively significantly improved seedling growth of <em>Jatropha curcas</em> compared to the other treatments and could therefore be recommended for <em>Jatropha curcas</em> nursery for improved production of the crop in sub-Sahara Africa.</p> O.

However, information on farmer’s knowledge about tomato diseases to warrant pesticide usage is scanty. Further, there is information gap on disease predisposing factor such as varietal choice and seed source. This study assessed the tomato farmers’ socio characteristic, varieties grown, seed source and knowledge of selected foliar fungal disease among tomato farmers in agro-ecological zones (AEZs) of Kirinyaga County. A cross sectional survey design that in cooperated purposive sampling and snowballing approaches was adopted in the study. Data were collected from 120 tomato farmers using structured questionnaires. A chi square (Ӽ<sup>2</sup>) test was used to examine the association between different variables at α= 0.05 using SAS version 9.4. No significant association (<em>p </em>&gt; 0.05) was observed between gender of farmers and AEZ. Nonetheless, there were more men (83.33%) than women (16.67%). Terminator F1 variety was popular among farmers (25%). No significance (<em>p</em> &gt; 0.05) association was observed between source of tomato planting material and AEZs. However, Agrovet was a popular seed source among farmers (40%). The reasons for choosing a particular tomato variety was significantly (<em>p</em> &lt; 0.05) associated with the AEZ with 40.83% of farmers preferring tomato varieties with good marketability traits such as fruit size. Farmers’ knowledge of causative agent of early blight, late blight and <em>Septoria</em> leaf spot was significantly (<em>p</em> &lt; 0.05) associated with AEZs. The source of farmer’s knowledge on tomato foliar fungal diseases was not significantly (<em>p</em> &gt; 0.05) associated with AEZ. However, farming experiences was a popular source of knowledge (51.67%) among farmers. Inability of some farmers to identify tomato diseases negates the efforts on disease management in tomato production in Kirinyaga County. Therefore, measures such as coordinated education on tomato diseases is necessary to empower farmers on disease causes and identification to enhance disease management and improve tomato yields in Kirinyaga County in Kenya.</p> Ogolla O.

From the Ashanti and Western North regions of Ghana, two colleges of education were chosen using a purposeful selection technique. 350 pre-service teachers from the chosen colleges made up the study's population. Scores from the pre-and post-tests for the pupils were submitted to a quasi-experimental design. While the students in the control group were taught the same concepts using the traditional method, the students in the experimental group learned agricultural concepts through computer-assisted instruction (CAI). The traditional mode of instruction included lectures, group discussions, and question and answer sessions. The study's results demonstrated that pre-service teachers who received CAI performed better than their counterparts who received traditional classroom teaching. Recommendations about the necessity of creating pertinent CAI packages for teaching agriculture in Ghanaian colleges of education were made based on the research findings.</p> Collins Agyei Menka, Bismark Osei-Mensuoh ##submission.copyrightStatement## https://journalajahr.com/index.php/AJAHR/article/view/185 Wed, 14 Sep 2022 00:00:00 +0000 The Role of Marginal Farmers' Farming Enterprises in Ensuring Household Food Security https://journalajahr.com/index.php/AJAHR/article/view/186 <p>The goal of this study was to ascertain how marginal farmers' farming operations impacted household food security. Additionally, efforts were undertaken to identify the challenges marginal farmers faced in attaining household food safety. Due to this, the study was carried out in three randomly chosen villages in the Rajbari district's Baliakandhi upazila. In these three communities, out of 500 marginal farmers, 26% of the populace was randomly selected. Data was acquired through direct interviews with marginal farmers between January 5 and February 20, 2009. The majority of marginal farmers (51%) fell into the medium group in terms of the contribution of farming enterprises to domestic food safety, while 37% fell into the low category. More over half of the family's food requirements were still unmet by the farming operations, which only met 40% of them annually. The biggest percentage of age (42%) of the four farming enterprise categories came from crops alone. Among the ten traits of the marginal peasants, the size of the farm and the yearly family income were positively connected, whereas the size of the family, the annual nutritional demands of the family, and cropping intensity practiced were negatively correlated. The remaining traits were not significantly correlated with how much farming operations contributed to household food security. Lack of suitable land for farming, poor training facilities, and ignorance of various facets of better farming enterprises were the main challenges marginal farmers faced in achieving household food security.</p> Humayun Kobir, Md.

Accordingly, a field experiment was carried out in Salinity Management and Research Center, Soil Resource Development Institute, Batiaghata, Khulna during Kharif-1 season of 2021 to investigate the effect of different types of mulches on soil salinity and yield of pumpkin. The experiment includes three treatments viz. no mulch (control), straw mulch and mulching paper. The experiment was carried out in Randomized Complete Block Design with four replications. Soil salinity was recorded at 30 days intervals. All mulching materials effectively reduced the salt accumulation in the root zone. After three months of seed sowing, the highest soil salinity (11.32 dS/m) and lowest soil salinity (6.24 dS/m) were found at no mulch (control) and mulching paper treatment respectively in the month of May. Mulching treatments markedly increased the growth and yield attributes of pumpkins. The highest value of three growth parameters i.e., fruit length (26.92 cm), fruit diameter (94.09 cm) and fruit size (2037 cm<sup>2</sup>) was found on mulching paper as compared to control. Again, the highest flesh thickness (3.94 cm), fruit weight (4.73 kg) and yield (31.18 t/ha) were recorded at mulching paper treatment whereas the lowest yield (16.68 t/ha) was found at no mulch (control). The results revealed that the use of mulching paper decreased salinity and also increased the yield of pumpkin in saline soil. These findings suggest that the application of mulching paper not only reduces soil salinity but also increases the yield of pumpkins.</p> Amarendranath Biswas, Ajay Kumar Biswas, G. M.

The split-plot experimental design was used. The treatments consist of two factors, the two-level water regime (30% useful water reserve and 70% useful water reserve) in main plots and the three-level inoculation (no inoculation, <em>Glomus mosseae</em> and <em>Glomus aggregatum</em>) in subplots. Each treatment is replicated nine times. The study was conducted at Agronomic Experimentation Station of the University of Lomé between June to November 2020. Induction of deficit hydric started three months after the setting up of the trial and lasted two months. At the end of the water shortage cycle, growth parameters were measured and leaf and soil samples were taken for laboratory analysis. Parameters assessed include mycorrhization rate, relative water content, leaf proline content, malondialdehyde content, mycorrhizal dependency, plant biomass and mineral content of the soil. The results show good mycorrhization rate, 70.86% for <em>Glomus aggregatum</em> and 54.92% for <em>Glomus mosseae</em> with mycorrhiza dependency of 12.87% and 11.74% respectively. Mycorrhizal inoculation reduced water stress symptoms in addition to the plant's intrinsic protective mechanisms. This was reflected in lower leaf proline and malondialdehyde content and improved relative water content of stressed but inoculated plants compared to uninoculated plants. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The AMF also improved the availability of mineral nutrients in the soil, which resulted in better growth of inoculated plants under both water stress and normal watering conditions. The overall assessment of the research suggested that AMF can be used to improve cashew seedlings resistance against drought and to improve their growth through improvement of soil nutrient availability.</p> Alèdi Assih, Amen Yawo Nenonene, Atalaèsso Bokobana ##submission.copyrightStatement## https://journalajahr.com/index.php/AJAHR/article/view/199 Sat, 08 Oct 2022 00:00:00 +0000 Bulb Size Effects on Flowering and Bulb Production of Tuberose (Polianthes tuberosa L.) cv.

A field experiment was conducted to evaluate the growth, yield and shelf-life response of cucumber (Classico F1 and Poinsett-76) to fertilizer applications. The experimental design was a randomized complete block in split plots with three repetitions of the treatments; Control (To: No fertilizer application), poultry manure (T1:20t &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ha<sup>-1</sup>), urban waste compost (T2:20t ha<sup>-1</sup>), NPK-20-10-10 (T3:0.7t ha<sup>-1</sup>), poultry manure (10t ha<sup>-1</sup>)+NPK-20-10-10 (0.35t ha<sup>-1</sup>) (T4), poultry manure (10t ha<sup>-1</sup>)+urban waste compost (10t ha<sup>-1</sup>) (T5), urban waste compost (10t ha<sup>-1</sup>)+NPK-20-10-10 (0.35t ha<sup>-1</sup>) (T6). Collected data on growth and yield variables from emergence till harvest were analyzed for variation in R version 4.0.1. Results showed that variety and fertilizer had a significant effect (<em>P</em> &lt; 0.05) on all growth variables with Classico F1 variety recording the highest mean values for all growth and yield variables. T1 recorded the highest in all growth variables (vine length, No. of leaves and stem diameter), except for the leaf area in T5 of Classico F1 (404.20 cm<sup>2</sup>) with the lowest in T0 of Poinsett-76 (87.87cm<sup>2</sup>). Variety, fertilizer treatments and interactions showed significant effects (<em>P</em> &lt; 0.05) on yield variables. Classico F1 was superior to Poinsett-76, yielding 31.91tha<sup>-1</sup> in T1 while Poinsett-76 produced 20.36tha<sup>-1</sup> in the same treatment. The lowest yield was recorded in the control treatments (4.45 tha<sup>-1</sup> for Poinsett-76 and 7.55 tha<sup>-1</sup> for Classico F1). Shelf-life evaluation showed the highest weight loss (20%) in fruits obtained in NPK-20-10-10 treatments within 21 days of storage. These results revealed that the integration of poultry manure or urban waste compost and chemical fertilizer (NPK-20-10-10) improves the growth and yield of cucumber as well as the shelf-life of harvested fruits in the western highlands of Cameroon.</p> Asafor Henry Chotangui, Marie Solange Mandou, Honore Beyegue-Djonko, , Primus Azinwi Tamfuh, Delphine Atabontsa, Swirri Christabel Shu Waa, Franck Junior Ngandjui Tchapga, Eric Bertrand Kouam ##submission.copyrightStatement## https://journalajahr.com/index.php/AJAHR/article/view/203 Mon, 17 Oct 2022 00:00:00 +0000 Evaluation of Fungicides against Downy Mildew (Peronospora destructor Berk) of Onion (Allium cepa) in Bale Zone, South Eastern Ethiopia https://journalajahr.com/index.php/AJAHR/article/view/204 <p><strong>Aims: </strong>To evaluate the efficacy of tested fungicides against downy mildew of onion and determine the appropriate interval of fungicides application.</p> <p><strong>Study Design: </strong>The experiment was laid out down in randomized complete block design with three replications for each treatments.</p> <p><strong>Place and Duration of Study:&nbsp; </strong>The experiment was carried out in farmers field of Aloshe village; Goba district of Bale zone in 2018/2019 during “Bona Season”.</p> <p><strong>Methodology: </strong>Locally available onion variety and two tested fungicides (Mancozeb (Mancozeb 80 Wp) and Ridomil (Ridomil Gold MZ 68WG) were used.

Lam] Genotypes in Umudike, Nigeria https://journalajahr.com/index.php/AJAHR/article/view/205 <p>Genotypes of the sweet potato (<em>Ipomoea batatas</em> (L.) Lam) normally exhibit high variability in their morphological characters. A field experiment was carried out in 2017 at the National Root Crops Research Institute, Umudike, Abia State, Nigeria to assess the morphological diversity among the population of 68 first filial generation (F<sub>1</sub>) sweet potato genotypes (Ligri PC) derived from seeds produced through poly cross systems from the International Potato Center, Kumasi, Ghana, including two local check varieties (UMUSPO3 and TIS87/0087). A randomized complete block design with three replicates was used to set up this experiment. The morphology descriptor was used to evaluate the genotypes of sweet potatoes on sixteen characters that covered both folial and fresh storage root morphology. The data were then subjected to an analysis of variance to identify any differences between the measured morphological parameters and agronomic variables. Using cluster analysis, it was established that all of the genotypes could be categorized into four distinct groups based on their physical characteristics. Consequent, a vast gene pool would provide for effective recombination to create a viable sweetpotato variety with high agricultural value.</p> Gamaliel I. Harry, Ulasi, J. Ifeanyi, Okoiseh G.

The experiment was set up in a split-plot design, composed of sixteen (16) treatments in three (03) replicates each. Four varieties: Ikenné (V<sub>1</sub>) Tzee (V<sub>2</sub>), Sotubaka (V<sub>3</sub>) and Sammaz 52 (V<sub>4</sub>) and four fertilization schemes: 0 kgha<sup>-1</sup> (F<sub>0</sub>); 200 kgha<sup>-1</sup> of NPK: 15-15-15+100 kgha<sup>-1</sup> of urea 46%N (F<sub>1</sub>); 6&nbsp;000 kgha<sup>-1</sup> of chicken dungs (F<sub>2</sub>) and 6&nbsp;000 kgha<sup>-1</sup> of small ruminant dungs (F<sub>3</sub>) were the studied factors. Maize grain yields were determined, and an economic analysis was done. The results analysis showed that varieties and fertilization schemes significantly affected maize grain yields. Sotubaka (V<sub>3</sub>) was the most productive variety during the two years of experiment. The average yield obtained under V<sub>3 </sub>(3.56±0.65 t ha<sup>-1</sup>) was higher than those of Ikenné, Tzee and Sammaz 52 varieties respectively by 20, 57 and 5%. The average yield recorded under F<sub>2</sub> was higher than those of F<sub>0</sub>, F<sub>1</sub> and F<sub>3</sub> by 54, 3 and 17% respectively. On a 2-year average basis, the application of 200 kgha<sup>-1</sup> of NPK: 15-15-15+100 kgha<sup>-1</sup> of urea 46%N (F<sub>1</sub>) gave the highest maize grain yields under V<sub>1</sub> (3.43±0.13 t ha<sup>-1</sup>) and V<sub>2</sub> (2.60±0.15 t ha<sup>-1</sup>); while the highest maize grain yields under V<sub>3</sub> (4.29±0.12 t ha<sup>-1</sup>) and V<sub>4</sub> (3.95±0.11 t ha<sup>-1</sup>) were obtained with the supply of&nbsp; 6&nbsp;000 kgha<sup>-1</sup> of chicken dungs (F<sub>2</sub>). On the same 2-year average basis, the highest profits were obtained under Ikenné (343 000 FCFA ha<sup>-1</sup>=US$ 512.46) and Tzee (177 000 FCFA ha<sup>-1</sup>=US$ 264.45) with the application of F<sub>1</sub>. For Sotubaka (480 000 FCFA ha<sup>-1</sup>=US$ 717.14) and Sammaz 52 (415 000 FCFA ha<sup>-1</sup>=US$ 620.03), the highest profit was obtained with the application of F<sub>2</sub>.

One such modification that has proven successful in boosting yield of many vegetable crops in recent years is the adaptation of the apex cutting technique, especially in unfavorable agro-climatic circumstances where traditional methods are not plausible. This study was&nbsp;to assess the effect of cutting the main stem apical bud on roselle growth parameters&nbsp;and determine the optimal stage of apex cutting. The experiment was conducted in a split plot experimental device in randomized blocks with four (4) repetitions at Tara/Gaya and Tarna/Maradi. Two factors were studied, six (6) roselle ecotypes and four (4) levels of apex cuttings viz. C0 (uncunt plants as a control); C1 (20 days after sowing (DAS)); C2 (30 DAS); and C3 (40 DAS). The findings showed that apex cutting significantly affected all the morphological parameters evaluated. Apex cutting significantly reduced the total plant height and the number of primary branches per plant. Furthermore, significant increases were observed in the diameter and the number of secondary branches per plant for the six ecotypes. Moreover, the optimal time-point for obtaining the best collar diameter and secondary branches per plant was found to be between cut 1 (20 DAS) and cut 2 (30 DAS).</p> Kaka Kiari Boukar Kéllou, Abdourazak Alio Moussa, Illo Souley Mahaman Hamissou, Mamadou Chetima Maina Boukar, Moussa Massaoudou, Atta Sanoussi, Bakasso Yacoubou, Mahamane Ali ##submission.copyrightStatement## https://journalajahr.com/index.php/AJAHR/article/view/207 Mon, 14 Nov 2022 00:00:00 +0000 Genetic Analysis of Morpho-metric Traits and Correlations of Yield Parameters in Soybean (Glycine max L. Merr) https://journalajahr.com/index.php/AJAHR/article/view/208 <p>Top crosses comprising 2 testers and 8 lines were made in the screen house using Line × Tester model. Observations were made on days to flowering, pod maturity, harvest, pods per plant, branching pattern, seeds per pod, 100 seed weight and yield/ha; crude protein, crude fiber, carbohydrate, moisture, ash and oil, as well as trypsin, tannins and phytate. Data collected were subjected to Analysis of Variance and the means separated using Duncan Multiple Range Test (DMRT), at 5% probability level. Genetic component analysis was carried out on the traits using Analysis of Genetic Design (AGD-R) package, to determine heritability, General Combining Ability (GCA) and Specific Combining Abilities (SCA). Results of the study revealed that, positive GCA values were recorded by TGM954 (0.01), TGM120 (0.07), TGM553 (0.70), TGM555 (0.58), TGM574 (0.19), TGM584 (0.14) and TGX1904-6F (0.12) for 100 seed weight; TGM954 (76.83) and TGM584 (12.54) for seed yield. Generally, TGM954 was a better general combiner than TGM951, because it combined well with other varieties for yield and yield-related traits. High heritability estimates were recorded for 100 seed weight (84.10%), number of branches (86.61%), days to flowering (91.69%), pods per pod (88.48%) and seed yield (86.07%). It can be concluded, that, crosses using Line × Tester model is encouraged for trait transfer and enhancement of soybean seed yield.</p> D. O. Ibirinde, A. O. Kolawole, C. O. Aremu, K. Balogun, M. N.

The experiment was laid out in a complete randomized design (CRD) and replicated thrice. Seed vigour indicators were number of sprouting, mean emergence time, germination percentage, seedling fresh weight (g), seedling dry weight (g), seedling root length (cm), seedling vigour index I and seedling vigour index II. The seed matrices measured were hundred seed weight (g), seed width (mm), seed length and seed thickness (mm). From the results obtained, the strong, positive and significant (1.00) relationship between the 100 seed weight and seedling germination percentage indicated that, maize germination is mostly determined by its size.&nbsp; Further, the most effective high vigour indicators are root length, seedling length, germination percentage, mean emergence time and number of sprouting at 4 days. However, M1155 recorded the highest seedling (72.33), with the highest corresponding germination percentage of 98%.</p> D. O. Ibirinde, N. M. Iliya, S. S.

Five tomato genotypes and ten offspring (F<sub>1</sub>), obtained from a 5×5 diallel crosses were sown in plots, arranged in a Randomized Complete Block Design, with three replicates. Data were collected on plant height (PH), number of cluster per plant, days to 50% flowering (50%FL), individual fruit weight (IFW), number of fruits per plant (NFPP), pericarp thickness (PT), number of lobe (NOL), number of seeds per fruit (NSPF), fruit lycopene (LYCOP), ascorbic acid content (ASCO) and fruit yield (YH). Data collected were subjected to Analysis of Variance (P=0.05). Also, diallel analysis was carried out to determine the General and Specific combining abilities (GCA and SCA) of the parents and hybrids respectively, following the Griffing (1956) Method II for partial diallel analysis. Results obtained showed significant differences among the genotypes, for all the characters measured. Also, non-additive and additive gene actions were responsible for the genetic control of the traits. The ratio of GCA and SCA were &lt; 1 for Plant height, CPPL, 50%FL, IFW, NFPP, PT, NOL, NSPF, LYCOP, ASCO and YH thus revealing the preponderance of non-additive gene action. GCA analysis suggested that parents Uc-op and Ibadan-local were the best general combiners while, SCA performance suggested that FDT<sub>4 </sub>X FDT<sub>2 </sub>was the best specific combiner. Broad sense heritability for NOL, NSPF, LYCOP, and ASCO were above 90%, indicating that they were highly heritable while narrow sense heritability of NOL was very high (55% and 83% respectively), PH, NSPF, NFPPL and LYCOP were moderate ranging between 20% and 38%. It is concluded that high yielding tomato hybrids, best combiners and a guide line for the assessment of relative parents breeding potential of the parents could be established following diallel technique.</p> D.

Mushroom cultivation is a low-cost, high-return activity that has proven to be an additional source of income. Because the vegetarian population in our country's urban centers has adopted mushrooms in their diet due to their nutritious worth, mushroom producers in nearby rural areas have an excellent market for selling their products quickly and at a reasonable price. As a result, the mushroom benefits both producers and consumers, earning it the title of super food.&nbsp; Mushroom production can also be used to empower rural people, offer additional income for agricultural families, and address the issue of rural people's nutritional needs. Rural unemployed people are the most productive workforce in the economy, necessitating efforts to enhance and strengthen their socioeconomic condition. Mushroom farming all year can produce revenue from the sale of spawns as well as the sale of fresh mushrooms in a sustainable manner by using farm by-products as a raw material.</p> Satish Chand, Bihari Singh ##submission.copyrightStatement## https://journalajahr.com/index.php/AJAHR/article/view/177 Fri, 10 Jun 2022 00:00:00 +0000 Socio, Economic and Cultural Importance of Betel Vine (Piper betle L.)
