Safflower cultivarsBy: A. E. Sharief

Abstract

To investigate the effect of seed priming treatments i.e. NaCl or KNo3 and non-primed seed of some safflower cultivars i.e. Giza 1, Line 168, and Line1697 on critical stage of germination under salinity concentrations of. 0, 3, 6, 9, 12, 15 and 18 dSm-1 NaCl. Continue reading

fruit in tomatoBy: Jamileh Rahaii

Abstract

To investigate the magnitude of heterosis, metaxenia and cytoplasmic effects of qualitative traits, such as the percentage of total soluble solids, the percentage of titratable acidity, pH, total soluble solids/titratable acidity ratio, Continue reading

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
