The field experiment entitled “Growth, lodging and yield of transplanted rice (Oryza sativa L.) under Kashmir conditions as influenced by nitrogen and silicon applications 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), phosphorus (9.3kg ha), potassium (221.60kg ha) and low available silicon (280.23kg ha). The experiment was laid out in Factorial Randomized Completely Block Design assigning combinations of nitrogen levels and silicon applications with four replications. The results revealed that the growth character viz. dry matter accumulation was significantly highest with 180kgN ha from 30-45DAT. But from 60DAT upto at harvest, dry matter accumulation was significantly highest with 120kgN ha during 2014 and 2015. Culm thickness was significantly highest with 120kgN ha at all growth stages during both the years. Internodal length (except mid tillering) were significantly superior with 180kgN ha at all growth stages during both the years. The lodging parameters viz. breaking resistance and bending moment were significantly highest with 120kgN ha while lodging index decreased with the same treatment during both the years. Significantly highest grain yield (75.61q haand 76.39q ha) and straw yield (93.38 q ha and 94.56q ha) were recorded with 120kgN ha during both the years respectively. So far as application of silicon is concerned, 15%Si caused significant improvement in crop growth parameters viz. dry matter accumulation, culm thickness and internode length during 2014 and 2015. Similar trend was also observed for grain yield (76.41q ha -1 and 77.11q ha) and straw yield (94.36q ha and 95.09q ha) during both the years. The lodging parameters viz. breaking resistance and bending moment were significantly highest with 15%Si while lodging index decreased with the same treatment during both the years.
