Abstract: An investigation entitled “Effect of micronutrient fortified Konkan Annapurna Briquettes on yield of Alphonso mango (<em>Mangifera indica</em> L.) in lateritic soils of Konkan” was undertaken in mango orchard of Department of Horticulture, College of Agriculture, Dapoli during the year 2016-17 and 2017-18. The field experiment was laid out in Randomized Block Design with three replications and ten treatments comprising of absolute control (T₁), Recommended Dose of Fertilizers (RDF) (T₂), RDF + copper through copper sulphate @ 15 kg ha^-1 (T₃), RDF + boron through borax @ 10 kg ha^-1 (T₄), RDF + molybdenum through sodium molybdate @ 0.250 kg ha^-1(T₅), RDF + copper through copper sulphate @ 15 kg ha^-1 + boron through borax @ 10 kg ha^-1 + molybdenum through sodium molybdate @ 0.250 kg ha^-1 (T₆), 100 per cent RDN through Konkan Annapurna Briquettes (KAB) (T₇), 100 per cent RDN + copper through copper sulphate @ 15 kg ha^-1 + boron through borax @ 10 kg ha^-1 + molybdenum through sodium molybdate @ 0.250 kg ha^-1 through Konkan Annapurna Briquettes (KAB) (T₈), 80 per cent RDN + copper through copper sulphate @ 15 kg ha^-1 + boron through borax @ 10 kg ha^-1 + molybdenum through sodium molybdate @ 0.250 kg ha^-1 through Konkan Annapurna Briquettes (KAB) (T₉) and 60 per cent RDN + copper through copper sulphate @ 15 kg ha^-1 + boron through borax @ 10 kg ha^-1 + molybdenum through sodium molybdate @ 0.250 kg ha^-1 through Konkan Annapurna Briquettes (KAB) (T₁₀) and FYM @ 50 kg tree^-1 was applied to all the treatments. The application of 50 kg FYM tree^-1 + 100 per cent Recommended Dose of Nitrogen + copper through copper sulphate @ 15 kg ha^-1 + boron through borax @ 10 kg ha^-1 + molybdenum through sodium molybdate @ 0.250 kg ha^-1 through Konkan Annapurna Briquettes (T₈) recorded the significantly highest mango yield per tree (67.53 kg tree^-1 in first year and 80.07 kg tree^-1 in second year) and maximum number of fruits (271.04 in first year and 304.37 in second year). The treatment T₁ <em>i.e.</em> absolute control recorded the significantly lowest mango yield per tree (21.62 kg tree^-1 in first year and 19.63 kg tree^-1 in second year) and minimum number of fruits (97.03 in first year and 83.70 in second year).
