Abstract: Tomato (Lycopersicon esculentum Mill.) is one of the most important edible and nutritious vegetable crops in the world. In Ethiopia there is a huge market for tomato as it is widely used as fresh and processed forms. The objective of the experiment is to select released tomato varieties with participation of local farmers for specific areas/location. Four varieties of tomato, which includes two processing type (Melka Shola and Melka Salesa) and two fresh market type (Bishola and Gelilema) were evaluated and selected on farmers field of Toke kutaye and Ambo Agriculture Research Center (AmARC on station) to identify and select the best performed varieties. RCBD design with three replications were used for evaluating the varieties. Combined analysis of variance of the two-year results showed that the varieties have highly significant difference on number of fruits per plant, fruit size, marketable fruit yield and total fruit yield. The highest total fruit yield was obtained from variety melka shola both on station and on farm (628.33 and 655.35 qt/ha); followed by melka salsa, (628.58 and 599.02 qt/ha), Gelilema (620.75 and 584.03 qt/ha) whereas, the lowest yield was obtained from Bishola (495.47 and 459.00qt/ha). The two-year results showed that Melka shola was much better on their inherent yielding potential to the area as compared to the other varieties. Thus, depending on the statistical result and farmers demand Melka shola was best variety in West Shewa and it’s better to multiply the seed of this variety for seed multipliers.

Abstract: Farmlands are being developed as a result of the high demand for food crops. The experimental trial was conducted under field conditions at Jimma Agricultural Research center, Agaro and Gera sub centers during the main cropping season of 2018 to 2021. The objective of the study was to assess the growth performance and forage yield of herbaceous forage legumes intercropped with coffee. The experiment was carried out in a randomized complete block design with three replications. Data on plant height, number of branches per plant, fresh and dry matter yields were collected and analyzed using the general linear model procedures in the R software, and the least significant difference was used to compare treatment means. The combined analysis of variance showed the presence of significant differences (P<0.05) among treatments, environments, and interaction effects. The treatment x environment (G x E) interactions also showed significant (P <0.05) difference for all measured agronomic traits except plant height. Mucuna pruriens had higher/taller plant height among the legumes, followed by Desmodium species. The lowest mean plant height was recorded from Stylosanethes species. Stylosanthes and Desmodim species gave the highest fresh biomass and dry matter yields, while Mucuna pruriens produced the lowest. At Gera, the forage legume dry matter yields were by far the highest of the three sites. However, further studies are required to examine the cost benefit on soil fertility and weed control of the legume forages used as a cover crop.

Abstract: Current work was conducted to evaluate 4 biotic and 8 abiotic agents, as seed soaking, against maize late wilt disease caused by Magnaporthiopsis maydis. It was performed in vitro and in vivo to achieve satisfied degree of disease control. Obtained results revealed that all tested fungicides in all doses were in vitro effective and completely inhibited M. maydis growth. Used fungicides herein ranked the first for antifungal activity followed by Pseudomonas fluorescens, sodium and potassium silicate. Greenhouse and field experiments showed that, Strong-X fungicide exhibited stability in its activity against the disease incidence with significant differences compared with the control. However, yield parameters obtained following the tested fungicides, even with the high application dose, were insignificantly different from the control. Meanwhile, potassium and sodium silicate as well as P. fluorescens were equivalent or superior the tested fungicides in protecting maize plants from wilt. Furthermore, sodium silicate significantly enhanced the 100-kernel weight (100KW) and net grains weight of ear (NGWE) per plant, whereas potassium silicate increased NGWE/plant only. On the other hand, soaked seeds in the suspension of Enteromorpha flexuosa and Ulva fasciate exhibited high performance for disease reduction with both application doses in the field and significantly reflected only on NGWE/plant. It could be concluded that the ecofriendly agents; potassium silicate, sodium silicate, P. fluorescens, E. flexuosa and U. fasciate are promising for control the disease. Further studies are needed to test other application methods of these promising materials against maize late wilt disease to maximize the obtained benefit.
