Evaluation of Nitrogen Fertilizer and Lime on Grain Yield, Protein Content and Kernel Weight of Barley (Hordeum vulgare L.) in Kenya

Nadir S. Waluchio, Caleb O. Othieno, Wilson K. Ng’etich & Julius O. Ochuodho · International Journal of Plant & Soil Science · 2015

Barley requires adequate nitrogen (N) for high grain yields and quality malting, but the balance between adequate and excessive N is important therefore field experiments were set up between July 2011 and July 2012 to evaluate the effects of nitrogen fertilizer rates and liming o...
