The form of agriculture and cropping system found throughout the world are the results of variation in local climate, soil type, and a range of socio the main determinants of the physical ability of crops to grow and cropping system to exist. Field experiment was conducted at Mechara Agricultural Research Center during 2013; to determine the effect of cowpea and soybean inter (LER) and Gross Monetary Value (GMV) on system productivity. The treatments included two legume crops (soybean and cowpea), their planting time (simultaneously and at first weeding of sorghum),three planting patterns of legumes (double alternate plants within sorghum plants, two rows in between two rows of sorghum and both double alternate plants and two rows in between two rows of sorghum) along with sole crops (sorghum, soybean and cowpea). The experiment was conducted in randomized complete block design with three replications. Intercropping of cowpea in sorghum depressed sorghum yield. There was a variable response yield of soybean and cowpea due to legume planting time, planting pattern and their interaction. However, grain yields of both the legumes were significantly ( time of planting and planting pattern. Simultaneously planting proved significantly better than planting at first weeding of sorghum, while combination of double alternate sorghum plants with two rows in between sorghum rows proved significantly better in enhancing the yield in case of both the legumes. Partial and total LER (1.55) was significantly higher in sorghum/soybean intercropping. Highest gross monetar birr) was accrued from planting two rows of cowpea with the first weeding of sorghum in between the two rows of sorghum however, it was at par with simultaneous planting of cowpea in double alternate plants within sorghum plants a sorghum rows and two rows of soybean planted in between two rows of sorghum with first weeding in sorghum.

In many developing countries of rural areas, banana plays a significant role as source of economic growth, income, food security and nutrition. Seven dessert Banana cultivars were evaluated at West Hararghe, Mechara. The analysis of variance indicate that there were highly significant (p < .001) difference of all morphological traits except fruit diameter and fruit length. The highest yield ton ha −1 was recorded for variety of Giant Cavendish (11.83 ton ha −1 ) but statistically on par with Robusta (10.67 ton ha −1 ) and Williams −1 (10 ton ha −1 ) and farmers in the study areas prefer Giant Cavendish, Robusta and Williams-I for yield and different morphological traits. These varieties also have the highest number of leaves as well as pseudo stem girth and plant height. Therefore, the varieties viz., Giant Cavendish, Williams-I and Robusta are highly recommended to the society of west Hararghe zone. For future work, we recommended to conduct studies on nutritional quality leaves as feed for animals and fruit quality.

This experiment was aimed to evaluate the effect of amalgamated NPS chemical fertilizer on crop performance and nodulation of soybean (Glycine max L (Merrill)) varieties on acidic soil during 2020 cropping season. Varieties of soybean i.e “Katta” and “Korme” and six levels of amalgamated NPS chemical fertilizer were used in factorial arrangement within randomized complete block design with three replications. Nodule parameters were highly influenced (P<.001) by the main effect of amalgamated NPS chemical fertilizer levels. The highest grain yield (2390 kg ha-1) was obtained from application of 19(N) 38(P2O) 7(S), kg ha-1 .. “Katta”and “Korme” varieties of soybean were high yielder at level of 19(N) 38(P2O) 7(S), kg ha-1 combined NPS fertilizer application. Therefore, both varieties “Katta” and “Korme” with application of 19(N) 38(P2O) 7(S), kg ha-1 mixed chemical fertilizer were recommended for enhancing nodule development and seeds yield.
