A field experiment was carried out for two successive cropping seasons in 2017 and 2018 at Shama Bulket, Semen Ari Woreda, South Omo Zone, Southern Ethiopia, to determine optimum seed rate and inter-row spacing for food barley production. The experiment involved a factorial combination of three seed rates (80, 100 and 120 kg ha-1) and three inter-row spacing (20, 30 and 40 cm). The experiment was conducted using a randomized complete block design with three replications. The results indicated the treatments had significant effect in all parameters except plant height and spike length. Based on the result of this study, use of 30 cm inter-row spacing and 120 kg ha-1 seed rate is superior in grain yield (4481 kg ha-1) and total biomass (14.6 t ha-1). Therefore, use of 30 cm inter row spacing with seeding rate of 120 kg ha-1 can be recommended for food barley production at Shama Bulket kebele and its vicinity. Int. J. Agril. Res. Innov.

A field experiment was carried out during the 2017-18 cropping season at Jinka Agricultural Research Center on station, South Omo zone, Southern Ethiopia, to determine suitable legumes in cassava legume intercropping on yield and land use efficiency of both crops. The experiment consisted of 7 treatments (cassava with haricot bean, cowpea, and pigeon pea as intercrop compared with cassava, haricot bean, cowpea and pigeon pea as sole) laid in RCBD in three replications. Statistical analysis showed that, intercropping cassava with haricot bean, cowpea and pigeon pea resulted in 54, 56 and 21% greater land use efficiency than for either crop grown alone. The highest MAI was obtained by growing cassava with haricot bean (18310.8) followed by cassava with cowpea (14524.4) whereas relatively the lowest was cassava with pigeon pea (6005.6). Based on the present finding, intercropping of cassava with haricot bean had more economic advantage (52219.8 Ebirr) than the other crop combination or grown alone. Therefore, intercropping cassava with grain legumes such as haricot bean and cowpea is important to cassava farmers since it would provide additional crop yield during the early cassava growth stage with the same piece of land and more profitable related to cost benefit. Therefore, use of cassava intercropping with haricot bean can be recommended for cassava producing farmers at Jinka and its vicinity. Int. J. Agril. Res. Innov. Tech. 12(1): 30-33, June 2022
