Abstract
A field experiment was conducted at Krishi Vigyan Kendra- Bandipora, SKUAST-Kashmir to study Response of Boron nutrition on growth & yield of Rice grown under temperate conditions of Kashmir valley with four treatments of Boron @ 0 Kg/ha (farmers practice), T1: No Boron (control) recommended dose fertilizer of SKUAST-K, T2: 1 Kg borax/ha + recommended dose fertilizer of SKUAST-K, T3: 2 Kg borax/ha + recommended dose fertilizer of SKUAST-K. The significant results were obtained with Application of borax at 1 Kgs/ha resulted in Panicle sterility of 3.28% & the maximum Grain yield 68.25 Qtls/ha was recorded as compared to the Farmers Practice where Panicle sterility of 12.25% and grain yield of 61.05 Qtls/ha was recorded as farmers do not use boron fertilizers in their fields. Farmer was satisfied so far as Subsequent panicle initiation & grain yield obtained were redressed during the conduct of on farm trial. The farmers were suggested for applications of Soil application of Boron during seed bed preparation on the farmer’s field. As far as Economics is concerned, the farmers practice obtained the Net Return of (Profit) in Rs. 73000 Rs / ha as compared with Application of borax @ 1Kg Borax/ha + Recommended dose fertilizer of SKUAST-K obtained the Net Return of (Profit) I 87560 Rs/ha with B:C ratio of 2.08.
