NEW NITROGEN CARRIERS FOR RICE

Abstract

The results of a field experiment conducted at IARI with rice variety improved Sabar- mati showd that urea super granules, sulphur coated urea, neem cake coated urea, N-serve and coal polyacid treated urea were superior to ordinary urea. Spraying of a culture of phyllosphere N-2 fixing microorganisms isolated from water hyacinth also increased the rice yields The results obtained suggest that several alternatives are available for increasing the efficiency of nitrogen applied to rice.
