Abstract:
The field experiment entitled “Effect of nitrogen and silicon on growth and yield attributes of transplanted rice (Oryza Sativa L.) Under Kashmir conditions was conducted at Agronomy Research Farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir during Kharif season 2014 and 2015. The soil of the experiment was silty clay loam in texture, neutral in reaction with medium available nitrogen (442.88kg ha-1), phosphorus (9.3kg ha-1), potassium (221.60kg ha-1) and low available silicon (280.23kg ha-1). The experiment was laid out in Factorial Randomized Completely Block Design assigning combinations of three nitrogen levels (N1: 120, N2: 150, N3: 180 kg/ha) and four silicon applications (Si0: Control, Si1: 5%, Si2: 10% and Si3:15%) with four replications. The results revealed plant height was significantly highest with 180kgN ha-1 from 30DAT upto at harvest. Among silicon applications, plant height was significantly highest with 15%Si compared to rest of treatments during both the years. However, leaf area index were significantly highest with 180kgN ha-1 from 30-45DAT but from 60DAT upto harvest, leaf area index were significantly highest with 120kgN ha-1.With regard to the effect of silicon applications, leaf area index was significantly highest with 15%Si during both the years. The yield attributes viz. panicle length, spikelets panicle-1 and grains panicle-1 were significantly higher with 120kgN ha-1 while same yield attributes were significantly highest with 15%Si during both the years. Different nitrogen levels and silicon applications failed to influence the 1000-grain weight significantly
