 ABSTRACT

A field experiment was conducted during early Kharif 2015 on sandy loam soil at College of Agriculture, V.C. Farm, Mandya, University of agricultural Sciences, Bengaluru, Karnataka to study the effect of  different methods of micronutrients mixture application  on growth, yield and  nutrient uptake of mung bean in Southern Dry Zone (Zone 6) of Karnataka. The experiment was laid out in RCBD with twelve treatments including control, RDF alone, RDF +water spray / soil / foliar / seed treatment with MM (Fe, Mn, Zn, Cu, B, Mo and deficient micronutrients). Results revealed that application of RDF +foliar application of MM at 30 and 45 DAS recorded significantly superior yield of 1140.84 kg ha-1 which increased about 7.16 , 38.39 and 56.13 per cent over soil application of MM (Fe+Mn+Zn+Cu+B) along with RDF, RDF alone and control respectively.  However, grain yield with RDF +foliar application of MM at 30 and 45 DAS and RDF +Soil application of MM  treatments were statistically non-significant .Also significantly  higher uptake of micronutrients in grains  Fe, Mn, Zn, Cu and B (209.23,15.17, 32.31,14.78 and 57.64 mg kg-1) .  Suggesting the the supplementation of MM as basal enhances the early vigour thus helps in better yield. Similarly foliar application at later stages is responsible for translocation of assimilates to sink thus resulting in higher yield.

Key words: Greengram, Micronutrients mixture (MM), Foliar application, Soil application, Benefit cost ratio
