Influence of Nitrogen Supply on Photosynthesis, Chlorophyll Content and Yield of Improved Rice Varieties under Upland Conditions in Western Kenya

P. A. Sikuku, J. M. Kimani, J. W. Kamau & S. Njinju · Journal of Experimental Agriculture International · 2016

Rice (Oryza sativa) is a principal staple food crop in Kenya. However, its production is still low due to inherently low and declining soil fertility. This has resulted into food and nutritional insecurity and low living standards. The situation has been compounded by the ever es...

Evaluation of Different Improved Upland Rice Varieties for Low Soil Nitrogen Adaptability

P. A. Sikuku, J. M. Kimani, J. W. Kamau & S. Njinju · International Journal of Plant & Soil Science · 2014

Scarcity of nitrogen fertilizer is a major constraint to rice production particularly in developing countries. Low soil fertility prevalent in farmer’s fields has led to low rice yields and the ever escalating fertilizer prices have made this important input unaffordable to most...
