Nitrogen content in straw

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.
