To maximize yields of groundnut (Arachis hypogea) and sesame (Sesamum indicum), various agronomic studies were conducted under irrigated, high rainfall and marginal rainfall areas. The optimum planting time of groundnut in the middle Awash region is between mid-May and mid-June. At Didesa the best time is at about mid-July; at Gambela and Pawe late May is the ideal. A spacing of 60 cm between rows and 10 cm between plants is optimum for groundnut in the middle Awash; for Didesa area a row spacing of 50 cm is preferred. Groundnut should be weeded not later than four weeks after emergence with an additional hand weeding at about seven weeks. Herbicides vernolate at the rate of 3.96 kg a.i. /ha and nitralin at 1.32 kg a.i. /ha were effective against both broadleaf and grass weeds of groundnut. Moreover, metobromuron at 4.0 kg/ha was effective against annual broadleaf and grass weeds.
