Croton is a species of plant in the genus, Codiaeum, which is a member of the family, Euphorbiaceae. They have a wide range of variations in leaf shape and coloration that have fascinated breeders, landscapers, horticulturists, and gardeners and a huge number of cultivars have been fixed for commercial production. Because of this crotons are in very regular demand and there is the need for fast propagation methods, with low cost and that assures the formation of vigorous, high-quality seedlings. The study, therefore, assessed the growth response of croton cuttings to different growth media and plant growth hormonesviz: Aloe vera gel and IBA. A 3x3 factorial Randomized Complete Block Design (RCBD) made up of three growth media (coco peat, sawdust, and topsoil) and two levels of growth-promoting hormones (Aloe vera gel and IBA) and a control was used. The study was carried out at the Multipurpose Crop Nursery at the College of Agriculture Education, Mampong Campus. Data was collected on sprouting response, the number of leaves, and the number of roots. The results indicated that the different growth media and hormones influenced sprouting response of croton at days to 50%, 70%, and 100% sprouting significantly (p > 0.05). Croton cuttings that were grown on topsoil and treated with Aloe vera gel recorded earlier days to sprout. The number of leaves and roots was higher among croton cuttings grown on topsoil and treated with Aloe vera gel. On the other hand, croton cuttings grown on sawdust recorded the least number of leaves at 28, 42, 56, and 70 DAP.). The results were similar for the number of roots. The study concluded that croton cuttings that were grown on a combination of topsoil and Aloe vera gel resulted in the earliest shoot response and a higher number of roots and leaves followed closely by those of IBA.

Introduction: The nutritional composition of plant tissues is influenced by climatic conditions during their growth and development. Climate influences the growth rate, chemical composition and yield of crops. This study was conducted to evaluate the effect of growing periods on the nutritional composition of six cowpea varieties; Kenyan local variety (KLV), Indonesian local variety (ILV), Malaysian local variety (MLV), Japanese local variety (JLV) and two Kenyan varieties (K80 and KenKunde).

Methodology: The seeds were grown in an experimental glasshouse under three varying growing periods in 2015 and 2016, respectively. The effect of growing condition on moisture, protein, potassium, calcium, magnesium, manganese, iron and zinc content was assessed.

Results:  Moisture content varied from 67.9% to 78.0% and 81.1% to 88.8% in 2015 and 2016, respectively; while protein contents ranged from 7.3% to 14.6% and 18. 4% to 30.4% in 2015 and 2016, respectively. In 2015, there was a significant increase in moisture content, protein, K, Ca, Mg and Mn in KLV as temperature increased. This trend was different for ILV and MLV, which showed significant differences across growing periods with the June growing period showing the highest moisture, protein, K, Mg and Mn contents. In 2016, protein, Ca and Mg contents increased in response to increasing temperature across the growing periods. KLV and Kenkunde exhibited higher concentrations of most components.

Conclusion: There were significant differences among varieties and across growing periods in nutrient content implying both variety and climatic conditions affect nutritional composition.

Tomato (Lycopersicon esculentum Mill.) is major fruity vegetables grown in Ethiopia next to hot pepper. Although crops grown in the country its production and productivity is very low compared to the world average. Among the reasons for low its production and productivity, shortage of improved tomato varieties is the major one.  This experiment was done with the aim of evaluating tomato varieties and select high yielding cultivars. An experiment was conducted in bonga district Gambella region 2011/12 dry season under irrigated condition. Seven tomato varieties namely ARP Tomato D2, Fetan, Melkasalsa, Chali, Bishola, Gelila and  Roma-VF(as local check) and  were tested in randomized complete block design with 3 replications. The mean values of all parameters were subjected to two way analysis of variance using the Proc GLM procedure of  SAS 9.3. Then statistical significance of the mean of each parameter was determined using F-test and Duncan multiple range test procedure was used to compare differences between treatment means at 5% probability level. The analysis of variance showed statistically significant differences (p< 0.05) among varieties in all growth and yield parameters except days to 50% flowering. Among the tested tomato cultivars, Melkasalsa produced the largest fruit. The highest fruit yield was recorded by Melkasalsa followed by Bishola. we can conclude Melkasalsa and Bishola variety were the most productive and gave larger fruit compared to others. Hence, these varieties can be used by tomato growers under irrigated condition around Bonga area.

The study was conducted to analyze constraints to adoption of sweet potato processing technologies among actors in South East, Nigeria. Questionnaire was used to collect data from a sample of eighty (80) respondents used for the study. Data were analyzed using mean score, standard deviation, factor analysis and multiple linear regression analysis. Results indicated that sex, educational level, marital status, processing experience and access to extension service had a positive influence on the adoption of sweet potato processing technologies in the study area. The respondents were highly constrained by inadequate processing machines/equipment (=2.88), high cost of processing produce (=2.86), inadequate knowledge of modern sweet potato processing techniques (=2.84), inadequate capital for start-off (=2.84), high cost of labor (=2.83), poor credit facilities (=2.80) and scarcity of processing materials like sweet potato tubers (=2.43). These variable constraints were further subjected to factor analysis and the variables were named technical and infrastructural factors. It is recommended that processors should be encouraged to form cooperative society to enable them to pool their resources together to obtain credit facilities and sweet potato labour saving processing technologies in order to increase productivity. There is also a need for creation of awareness by extension agents, public health agencies, nutritionists and non-governmental organizations on the usefulness of orange fleshed sweet potato in addressing Vitamin A Deficiency Syndrome.
