Integrated nutrient management strategies in Eastern Uganda

A project of the CGIAR systemwide program on Soil, Water and Nutrient Management (SWNM), concerned with improving integrated nutrient management practices on small-scale farms in Africa, has been carried out in Kenya, Tanzania and Uganda for last two years (September 1999 to September 2001). The project aims to enable small-scale farmers to profitably reverse nutrient depletion of their soils b...

Stimulated fine root growth benefits maize nutrient uptake under optimized nitrogen management

Optimized nitrogen (N) management reduces total N application without sacrificing cropyield. However, the underlining mechanisms have not been well investigated, especially lackingthe evidence from roots. Here we performed a two-year field experiment with maize grownunder zero-N, conventional N and optimized N applications and examined grain yield, N,phosphorous (P) and potassium (K) uptake and...

Effects of Integrated Plant Nutrient Management (IPNM) Practices on the Sustainability of Maize-based Hill Farming Systems in Nepal

Maize is a staple summer crop grown in the hilly areas of Nepal, where the soil is fragile and fertility is declining over years due primarily to degradation of natural resource base, high rates of soil erosion, increased cropping intensity and inadequate replenishment of soil nutrients. Forum for Rural Welfare and Agricultural Reform for Development (FORWARD) with the financial support from Hi...

Integrated Nutrient Management in Rice: a Critical Review

Rice is an important food grain crop and is consumed by majority of the human population. Nutrient management is an important aspect in rice to be given pivotal importance so as to attain sustainability of grain yield production. In the present chapter, aspects’ relating to integrated nutrient management in rice is critically reviewed. The effects of integrating chemical fertilizers with organi...
