Grain Morphological Traits Confer Tolerance to Bruchid (Callosobruchus maculatus) Infestation of Stored Green Gram (Vigna radiata L. Wilczek)

Stephen K. Kung`ala, Onesmus M. Kitonyo, Dora C. Kilalo & Josiah M. Kinama · International Journal of Plant & Soil Science · 2026

Post-harvest losses due to bruchid (Callosobruchus maculatus) infestation in green gram production remain a challenge. The relative tolerance to bruchid infestation of five green gram (Vigna radiata L. Wilczek) varieties was evaluated under ambient conditions in a laboratory. The...

Regulation of Growth and Seed Yield in Chia (Salvia hispanica L.) under Contrasting Soil Moisture Regimes

Annie W. Muturi, Onesmus M. Kitonyo, John W. Kimenju & Monica W. Mburu · International Journal of Environment and Climate Change · 2026

As chia crop (Salvia hispanica L.) expands into new environments in Kenya, its response to moisture stress is only partially understood. This study simulated different soil moisture regimes to determine their effects on chia crop growth and yield, and to identify key traits that...

Green Gram-sorghum Intercropping: Effects on Crop Microclimate, Competition, Resource Use Efficiency and Yield in Southeastern, Kenya

Bernard M. Yumbya, Onesmus M. Kitonyo & Josiah M. Kinama · International Journal of Environment and Climate Change · 2024

A better understanding of cereal-legume interactions could improve the implementation of intercrop systems for cropping intensification. These interactions affect crop microclimates and the efficiency of utilizing growth resources such as water and nitrogen. In this study, four m...
