The field experiment was conducted at Agronomy Research Farm of SKUAST-K during Kharif season 2014 and 2015. Three N levels (N1: 120, N2: 150, N3: 180 kg/ha) and four Si applications (Si0: Control, Si1: 5%, Si2: 10% and Si3:15%) were applied to the rice crop. Number of tillers m-2 and relative growth rate were significantly highest with 180kgN ha-1 from 30-45DAT but from 60DAT upto harvest, these growth parameters were significantly highest with 120kgN ha-1 . However, number of tillers m-2 and relative growth rate were significantly highest with 15%Si. Nitrogen as well as silicon applications could not make any significant difference on their respective content of grain and straw. 120kgN ha-1 and 15%Si resulted in significantly highest nitrogen and silicon uptake by crop, respectively. The treatment combination with 120kgN ha-1 and 15% Si proved to be the best as it produced highest grain yield during both the years. | Impact of nitrogen and silicon on growth parameters and nutrient uptake of transplanted rice Oryza sativa L. under temperate conditions
