Abstract

Field experiments were conducted to evaluate the effects of ecofriendly organic matrix entrapped urea OMEU on growth productivity and yield of rice Oryza sativa L cv Basmati and soil enrichment in the paddy field at Rohtak Haryana located near Delhi The OMEU prepared in granular form contained cow dung rice bran grain cover of Oryza sativa powder of neem leaves Azadirachta indica and clay soil diameter of particles 002 mm in 1111 ratios and saresh plant gum of Acacia sp as binder along with half of the recommended dose of commercially available soluble urea free urea FU Single basal application of OMEU showed an increase in plant growth in terms of fresh and dry weights root length root leaf and tiller numbers soluble protein total N and ammonium in leaves productivity in terms of grain and straw yield and nutritional and microbial activities of field soil over free form of urea and no fertilizer application Nutritional status of rice grains was also improved over the free urea and no fertilizer controls Our data indicate that OMEU which is low cost and based on biodegradable nontoxic and locally available agrowaste can be attempted to replace the conventional use of soluble urea in rice
