Abstract: Rice (Oryza sativa L.) is one of the most important staple food crops belonging to the grass family (poaceae). It is the most consumed cereal after wheat, and has the second largest area under production following maize crop worldwide. Water requirement is the most thrust area in rice. Owing this, a field experiment was conducted in Vindhyan soil during the 2016 in Kharifseason at Agricultural Research Farm, Rajeev Gandhi South Campus, Barkachha Mirzapur. It is a campus of Banaras Hindu University, Varanasi. The experiment consisted 5 doses of nitrogen N0, N1, N2, N3 and N4 (0, 60, 80, 100, 120 kg ha-1) and selected 4 varieties of rice V1, V2, V3, and V4 (HUR-2-1, HUR-1-5, HUR-917, HUR-3022) laid out in a Factorial Randomized Block Design with three replications. In the experiment nitrogen treatment were used at three growth stages ( vegetative growth stage at 40 DAT, reproductive stage at 70 DAT, maturity stage at harvesting), among three application of nitrogen, ½ of the total nitrogen applied at time of 23 DAT and remaining doses of nitrogen applied at reproductive stage (flowering stages) and maturity stage(grain filling stage), in these nitrogen application recorded significant growth on N4 dose of nitrogen and N2&N3 doses of nitrogen no significance effect on rice growth and rice variety and V1 given significant growth performance. Among the treatments and varieties, significant differences were observed in vegetative growth of rice at 70 day after transplanting (DAT) with maximum plant height (95 cm), at harvesting (109 cm) and number of tillers (19/hill) was recorded in HUBR-2-1& HUR-105 at N4 kg Nha-1 while minimum plant height (65cm) and number of tillers (13/hill) was recorded in V3 at N4.(A. Das., M. K. Singh) The number of leaves (86 hill-1) and leaf area index (38) were recorded maximum in HUBR-2-1 at N4. Same trend were fallowed for root length and root volume. So this research result indicates that HUR-2-1 gives better vegetative growth at N4 dose of nitrogen treatment in Vindhyan region of Uttar Pradesh. In controlled plot rice plant ware stunted growth and unable to multiplication of tillers and panicle initiation (Choudhary, R. L. Kumar).
