Total nutrient uptake and grain yield of rice (Oryza sativa) as influenced by neem coated urea fertilizer

Abstract

Rice is the world's single most important food crop, being the primary food source for more than a third of the world's population and grown on 11% of the world's cultivated area. Agronomical trial on Paddy and Wheat crops with Neem coated Urea as source of Nitrogen has produced significantly higher yield. The experiment was laid out in randomized block design with ten treatments in three replications. The application of 100% RDN as NCU in 3 splits (Basal + Max Tillering + Panicle Initiation) recorded significantly higher number of filled grains (173.0) as compared to other treatments. The unfilled grains panicle-1 (16.03) was recorded non-significantly highest under the treatment of 100% RDN as PU as 3 splits (Basal + Max tillering + Panicle Initiation) (T1) as compared to all other treatments. Test weight, grain yield t ha-1, total uptake were recorded non-significantly highest under the treatment of 100% RDN as NCU in 3 splits (Basal + Max Tillering + Panicle Initiation).
