Yield potential and adaptability of medium duration Pigeonpea (Cajanus cajan L. Millsp.) genotypes in dry parts of North Rift Valley, Kenya – IJAAR

Cajanus cajanBy: Juliana J. Cheboi

Abstract

Pigeonpea is an important crop in Semi- Arid tropical and sub- tropical areas. Although it is reported to have wide adaptability to different climates and soils, 98.7% of its production in Kenya is concentrated mainly in three counties (Machakos, Kitui and Makueni) but remains neglected and underutilized in North Rift Valley.

Resistance of Kenyan wheat germplasm to Fusarium head blight and deoxynivalenol contamination – IJAAR

Fusarium head blight,By: John M. Wagacha

Abstract

Fusarium head blight (FHB) of wheat causes quantitative and qualitative reduction in yield. Cultivar resistance is the most effective method of managing the disease. This study evaluated the resistance of wheat germplasm currently available in Kenya to Fusarium head blight and deoxynivalenol (DON) contamination. Continue reading
