Abstract
A field experiment was carried out during the Kharif, 2017 at Rice Research Centre, Agricultural Research Institute, Rajendranagar, Hyderabad (TS), India to study the “Effect of Neem coated urea on yield attributes, yield, nutrient uptake and economics of rice (Oryza sativa L)”. The experiment was laid out in Randomized complete block design with three replications and eight treatments viz., T1- RDF 120-60-40 N through Prilled urea (PU), T2- RDF 120-60-40 N through Neem coated urea (NCU), T3- 95% Recommended dose of nitrogen (RDN) through NCU + Recommended dose of Phosphorus and Potassium (RDP and K), T4- 90% Recommended dose of nitrogen (RDN) through NCU + Recommended dose of Phosphorus and Potassium(RDP and K), T5- 85% Recommended dose of nitrogen (RDN) through NCU + Recommended dose of Phosphorus and Potassium(RDP and K), T6-80% Recommended dose of nitrogen (RDN) through NCU + Recommended dose of Phosphorus and Potassium(RDP and K), T7- 75% Recommended dose of nitrogen (RDN) through NCU + Recommended dose of Phosphorus and Potassium(RDP and K) andT8- 0 Nitrogen + Recommended dose of Phosphorus and Potassium(RDP and K) (Control). The results showed that T2- RDF 120-60-40 N through Neem coated urea (NCU) produced higher grain, straw yields and BC ratio whereas, T3- 95% Recommended dose of nitrogen (RDN) through NCU + Recommended dose of Phosphorus and Potassium (RDP and K) with 5% reduction in recommended nitrogen in NCU form produced the similar yields of grain and straw, BC ratio which were obtained in T2- RDF 120-60-40 N through Neem coated urea (NCU). Hence, T3- 95% Recommended dose of nitrogen (RDN) through NCU + Recommended dose of Phosphorus and Potassium (RDP and K) with 5% saving in recommended nitrogen in NCU form proved to be better for higher productivity and profitability of rice.
