Soil properties, growth and yield of cowpea. ![]() In Machakos County and Naivasha in Nakuru County, Kenya, aiming to determine theĪnd two levels of manure (plots with manure and plots without manure) on selected Zai pit technology was tested in two locations falling under Agroecological Zone IV ToĪddress the reduction in production, this study assessed the effect of Zai pit depths on selected soil propertiesĪnd cowpea growth and grain yield. Rainfall and temperature regimes, strongly affect agricultural productivity.
