Negative nitrogen balance represents a major factor causing low potato yield in potato
growing areas of Kenya while its excessive surplus poses a significant environmental …

Grain legume crops are a significant component of the human diet and animal feed and
have an important role in the environment, but the global diversity of agricultural legume …

Background For manipulating N 2 fixation and improve the N benefits to agricultural
legumes, there is a need to reduce the inhibitory effect of applied N on Rhizobia inoculant …

Compatible rhizobia populations are seldom available in soils where soybean has not been
grown before. Inoculating soybean seeds with superior rhizobia strains is necessary for …

Rhizobia are bacteria that are able to nodulate leguminous plants and fix nitrogen to make it
utilizable to plants thus making it beneficial as microbial biofertilizer. The aim of this study …

Aims: To evaluate the effects of water hyacinth compost prepared with various cultures on
growth and yield parameters of maize. Study Design: Randomized Complete Block Design …

Background Due to common bean derives lower nitrogen (N) from symbiotic N 2-fixation, it
requires N either from inorganic fertilizer or soil N. Field experiments were conducted at four …

The cost of chemical fertilizer is high and their use efficiency especially nitrogen fertilizer is
low. Use of biological nitrogen fixation as source of N and determining the optimum level of …

Bean production in Kenya barely meets half the demand because of low soil fertility among
other factors. While use of rhizobia inoculants can substantially increase bean yields, less …

Abstract Slash-and-burn (SB) agriculture degrades soil and reduces fertility, but provides
most of the food produced in tropical Africa. Soil biota can be manipulated to enhance soil …
