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.
