P. Monteiro C. Ogoshi D. A. Cardoso V. Perazolli <p><strong>Aims: </strong>This study aimed to measure the losses in the production of tomato plants caused by the bacteria <em>P. viridiflava</em>.</p> <p><strong>Study Design:</strong> Experiments were performed in a completely randomized design with six replicates.</p> <p><strong>Place and Duration of Study:</strong> The study was conducted on the Caçador experimental station of the Agricultural Research and Rural Extension Enterprise of Santa Catarina (EPAGRI) from October to April during 2017/2018 and 2018/2019 crop season.</p> <p><strong>Methodology:</strong> Bacteria were isolated from tomato plants with pith necrosis symptoms, using nutrient agar. The isolated strain was identified by a scheme of tests for bacteria that emit fluorescence, known as LOPAT, and by sequencing the 16S rDNA region. Tomato plants were cultivated for two seasons during 2017/2018 and 2018/2019. In the first year the cultivar Paronset was cultivated and in the next season the experiment was performed with the cultivars Compack, Nagai, Paronset and Pizzadoro. During the production season, tomato fruits were harvested and the weight was accounted for. At the beginning of the first bunch formation, the stems of the plant were inoculated with wood sticks containing bacterial colonies removed from a 48h-Petri dish culture medium. Tomato plants cultivated as control treatments were not inoculated. At the end of the cultivation seasons, the stems were cut to analyze the pith necrosis progress.</p> <p><strong>Results:</strong> In both cultivation seasons, there was no decrease in the production associated with the pith necrosis caused by <em>P. viridiflava</em> EPAGRI BacPvT1 because the total weight of fruits harvested from inoculated plants was not statistically different compared to the non-inoculated plants. The disease progressed in all inoculated plants and adventitious root formation as external symptoms was observed.</p> <p><strong>Conclusion:</strong> The bacteria <em>Pseudomonas viridiflava</em> EPAGRI BacPvT1, one of the etiological agents of pith necrosis of tomato, may not decrease the production. Even causing some injuries, it may be not cause any damage.</p> 2019-11-13T00:00:00+00:00 ##submission.copyrightStatement## Morphology and Yield Potentials of Lablab Bean Genotypes Grown in Early Kharif Season 2019-11-14T09:16:13+00:00 D. Deb Nath M. S. Islam T. Akter J. Ferdousi <p>An experiment was conducted during March 2014 to August 2014 at the experimental field of Sylhet Agricultural University (SAU), Sylhet to study the morphological variability, yield and yield contributing characteristics among the four lablab bean genotypes viz., SB003, SB010-1, SB011 and BP003. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The genotypes SB003 and SB010-1 had reddish brown seed coat color while it was black in SB011 and reddish color in the genotype BP003. Among the genotypes 100 dry seed weight was ranged from 34.00 g (SB010-1) to 42.00 g (SB011). Variation in yield and yield contributing characteristics were found among four lablab bean genotypes. The genotype SB003 produced the maximum number of pods plant<sup>-1</sup> (206.3) followed by SB010-1 (134.3) while it was minimum for the genotype SB011 (92.67). Similar trend was also noticed in case of pod yield plant<sup>-1</sup> among the genotypes. The highest pod yield was recorded in the genotype SB010 (7.73 ton ha<sup>-1</sup>) while it was the lowest in SB011 (2.87 ton ha<sup>-1</sup>). However, pod yield ha<sup>-1</sup> indicating bright scope to popularize lablab bean production during early kharif in Sylhet region.</p> 2019-11-14T00:00:00+00:00 ##submission.copyrightStatement## Influence of Pre-Harvest Bagging on Fruit Quality of Mango (Mangifera indica L.) cv. Langra 2019-11-11T08:32:13+00:00 Md. Tariqul Islam Md. Shazadur Rahman Mst. Moli Akter Md. Nazmul Hasan Md. Sorof Uddin <p>Fruits are susceptible to insect pest infestations, bird attack, various pathogens, and mechanical damages, all of which can reduce their commercial value and thereby cause significant yield and economic losses. The objective of this study was to control mango pests and diseases as well as to improve the fruit quality of mango through bagging technology. An investigation was performed during the year 2016 from March to July for safe mango production by applying minimum use of pesticide entitled studies on influence of bagging on physico-chemical properties and shelf life of mango cv. Langra. The mango fruits were bagged at marble stage (40 days from fruit set) with different types of bags which constituted the various treatments <em>viz</em>: T<sub>1</sub>: Brown paper bag; T<sub>2</sub>: White paper bag; T<sub>3</sub>: Polythene bag T<sub>4</sub>: Muslin cloth bag; T<sub>5</sub>: No bagging (control). Bagging with brown paper bag and white paper bag improved fruit retention, weight of fruit, diameter of fruit, pulp weight, total soluble solids, ascorbic acid, percent of citric acid, reducing sugars and β-carotene at harvest and ripe stage over control. Brown paper bag changed fruit color. In all cases good quality, cleaner, disease and insect free fruits were harvested. The sensory qualities in fruits of brown, white and muslin cloth bags were improved over control. Pre-harvest bagging also reduced occurrence of spongy tissue and the incidence of mealy bugs. These results indicate that fruit bagging can improve fruit quality through reduction in disease and insect-pest attack and shelf life of mango cv. Langra.</p> 2019-10-16T00:00:00+00:00 ##submission.copyrightStatement## Growth and Yield Response of Two Onion (Allium cepa L.) Varieties to Organic and Inorganic Fertilizers in the Forest- Savannah Transitional Zone of Ghana 2019-11-11T08:32:12+00:00 Ali A. Danje M. E. Essilfie E. K. Asiedu <p>The objective of the experiment was to evaluate the influence of organic and inorganic fertilizers on growth and yield of two onion varieties in the transitional zone of Ghana. The experiment was laid out in a split plot design with 3 replications. Two varieties [Bawku Red and Red Creole] were laid as main plots and fertilizer rates [10 t/ha Cow dung, 10 t/ha Poultry manure, 300 kg/ha NPK, 5 t/ha PM + 150 kg/ha NPK, 5 t/ha CD + 150 kg/ha NPK) and control (without amendment)] were assigned to sub-plots. The two field experiments were conducted in 2016 and 2017 cropping seasons at the research field of the College of Agriculture Education, University of Education Winneba, Mampong campus. The result showed that Bawku Red planted on 5 t/ha PM + 150 kg/ha NPK produced (P=.05) higher number of leaves per plant and shoot fresh and dry weight than the control during the 2016 cropping season. Red Creole planted on 10 t/ha PM had higher number of leaves per plant, taller plants and higher marketable bulb yield than the control during the 2016 cropping season. In both 2016 and 2017 cropping seasons, Bawku Red and Red Creole planted on 5 t/ha PM + 150 kg/ha NPK produced (P=.05) higher total bulb yield than the control. For maximum vegetative growth and yield in onion production, preferably Bawku red, sole poultry manure (10 t/ha) and/or in combination with NPK (5 t/ha PM+150 kg/ha NPK) is recommended.</p> 2019-10-24T00:00:00+00:00 ##submission.copyrightStatement## Effects of Seeds Source and Manure Type on Germination and Early Growth of Khaya senegalensis (Desr) A. Juss Seedlings in Bauchi State, Nigeria 2019-11-11T08:32:10+00:00 E. M. Abubakar E. K. Rabo <p><em>Khaya senegalensis (Desr) </em>A. Juss<em> is a perennial deciduous tree which has many uses in developing nations. The population of the tree is rapidly declining due to no conservation efforts to prevent the species from endanger and extinction. </em>At the moment there is dearth information on manure types required to raise healthy seedlings of the tree species in the study area. <em>To conserve this genetic resource, germination and early growth rate experiment was carried out using seeds collected from three locations (</em>eco-zones)<em> (Alkaleri, Bauchi and Toro). </em>Matured seeds of <em>K. senegalensis</em> were collected from mother tree stand in the three locations. One hundred and fifty seeds (150) from each location were sown in perforated polythene pots at an average depth of 2-3 cm. After germination i.e. 30 days after planting, different manures were applied to the seedlings. The experiment was laid out in a Completely Randomized Design (CRD) with three treatments, namely: poultry dung, cow dung and NPK manures; the experiment was replicated four times. Data on seeds germination variables of interest (seedling heights, number of leaves, collar diameter, leaf area, leaf width, leaf length and fresh weights) were measured. Seedlings height were measured using meter rule, collar diameters using a venier caliper, numbers of leaves were determined by manual counting the number of leaves on the seedlings, leaf area was measured by tracing leaves of seedling on a graduated graph sheet. Data collected on seed germination and early growth rate were subjected to descriptive statistics and inferential statistics (ANOVA). Where significant differences occurred, Tukey test was used to separate the means. Based on this finding, germination of seeds commenced after 10 to 14 days. Locations and manure types had significant effects on the mean heights, number of leaves, collar diameter, leaf area, leaf width, length and fresh weights of <em>K. senegalensis </em>seedlings in the study area. Thus, for species conservation and genetic heredity, seeds sourced from Bauchi eco-zone was the best with poultry manure as the best performed manure for the raising of <em>K. senegalensis </em>seedlings in the study area.</p> 2019-11-01T00:00:00+00:00 ##submission.copyrightStatement##
