Effect of boron on yield and economics of groundnut in boron-deficient soil series (Typic Rhodustalf) of Madurai district, Tamil Nadu

Boron is the yield-limiting factor for groundnut production in sandy loam soils of Madurai district, Tamil Nadu. Therefore a field experiment was conducted to evaluate the effect of boron on yield and economics of groundnut in boron-deficient soil series (Typic Rhodustalf) of the district at the farmer's field located at Alangampatti village of Melur block during Sep-Dec 2017 in a randomized block design with three replications. Twelve treatments were included and the results revealed that the application of 15 kg/ha of B as soil application and 0.5 per cent of B as foliar application at critical stages of crop growth along with the recommended dose of fertilizers (RDF) resulted in maximum pod and haulm yield (2013 and 3017 kg/ha respectively). Regarding the economics the application of soil (15 kg/ha) and foliar B (0.5%) along with RDF recorded the highest net return (Rs 67165) and B-C ratio (2.5) over no-boron application.
