Abstract
An experiment was conducted in farmer’s field at different locations of kole lands to study the effect of micro nutrient Boron on yield and soil nutrient status of rice during 2012-2014. The treatments comprised of different levels of B viz; 2.5 kg Borax/ ha, 5 kg Borax/ha, 10 kg Borax/ha, 12.5 kg Borax/ha, 15 kg Borax/ha and untreated control. Observations on growth characters, yield attributes, yield and soil and plant nutrient status were recorded. The application of 15 kg borax /ha recorded the maximum number of panicles/m2 , number of grains /panicles, thousand grain weight, grain and straw yield of rice. The results of pooled data on plant and soil nutrient status revealed that application of boron had a positive effect on uptake and availability of nutrients in soil. The study concluded that the soil application of borax@ 15 kg /ha was found to be good for correcting the deficiency in B deficient areas of Kole lands.
