Abstract: A field experiment was carried out during the Kharif season (June–October) of 2016 at the Research Farm of the Indira Gandhi Agricultural University, Raipur (C.G.), India to study the Response of applied neem coated urea (NCU) on yield and yield attributing parameters of rice (Oryza sativa L) in Vertisol. The experiment was laid out in a Randomized block design with three replications and eight treatments namely i.e. 100 % PU (3 splits), 75 % NCU (3 splits), 100 % NCU (3 splits), 125 % NCU (3 splits), 100 %NCU (full basal), 100 % NCU (2 splits 50%+50%), 100 % NCU (2 splits 75%+25%) and Control (No P60 K40). The results obtained in this study showed that the T4-125% Neem coated urea performed significantly better than the other treatments for almost all the agronomic yield attributing characters (number of tillers 323, number of panicle 345, panicle length 23.3cm, filled grain per panicle147, test weight of 1000 seeds of rice 28.6gm, grain 42.5 q ha-1 and straw 67 q ha-1 yields, nutrient uptake 103 kg ha-1 N, 18.8 kg ha-1 P and 190 kg ha-1 K. The chemical properties of soil viz pH 7.4, Electrical conductivity 0.26dSm-2, Available nitrogen 222 kg ha-1, phosphorus 14.3 kg ha-1, potassium 409 kg ha-1 was found higher in T4–125% Neem coated urea (3 splits) and lowest was found under control treatments at harvest stage of rice.
