Field experiment was conducted during early kharif2017 at College of Agriculture, V.C. Farm, Mandya to study the effect of soil and foliar application of micronutrients mixture on growth and yield of blackgram. Experiment was laid out in RCBD with fourteen treatments including control, RDF + FYM, foliar application of MM at 20 DAS (MMF1 and MMF2), 40 DAS (MMF1 and MMF2) along with RDF+FYM, Foliar spray at 20 and 40 DAS along with FYM+RDF and soil application of MMS1, MMS2, MMS3 and MMS4 along with RDF+FYM. These treatments were replicated thrice. Micronutreints mixture comprising Fe(20.10 g), Mn(18.20 g), Zn(160 g), Cu(12.73 g), with B(43.70 g)/without B, Mo(2.33 g) was prepared using appropriate micronutrients salts for foliar application per acre and Fe(80.4g), Mn(72.8g), Zn (640 g), Cu(50.92 g), with B(174.8 g)/without B, Mo(9.32 g) for MMS1 and two, three and four times that of MMS1 for other mixture (MMS2, MMS3 and MMS4, respectively) per acre for soil application. Results revealed that foliar application of MMF1 at 20 days after sowing and MMF2 at 40 days after sowing along + RDF+FYM recorded significantly higher plant height (51.17 cm), number of leaves per plant (14.07 )number of branches per plant (14.37),number of pods per plant (58.50), number of seeds per pod (7.47)and seed yield ( 1655.54kg ha-1)and dry matter (19.87 g plant-1)) of blackgram. While higher haulm yield (2424.61 kg ha-1) and was observed with MMS2 + RDF+FYM. The increase in yield and growth parameters was attributed to micronutrients nutrition through foliage.
