Nitrogen Nutrition in Rice

Nitrogen nutrition in rice though widely discussed, still modern concepts and findings are enriching us. It is also a difficult concept due to large variability of cultivation practices and environment. A clear idea of nitrogen nutrition will not only enhance productivity but also the nitrogen use efficiency. These concepts will be elaborated hereunder.

Nitrogen Nutrition of the Pineapple Plant ,

Unpublished studies in the files of the Pineapple Research Institute of Hawaii indicate that under present cultural conditions the .pineapp1e plant displays superior performance with a foliar applied combination of ammonium and nitrate nitrogen than with either form of nitrogen alone. The studies presented here were undertaken to evaluate ammonium nitrate as a nitrogen source under different so...
