Effect of micronutrient fortified Konkan Annapurna Briquettes on yield of Alphonso mango ( Mangifera indica L.) in lateritic soils of Konkan

Abstract

An investigation entitled “Effect of micronutrient fortified Konkan Annapurna Briquettes on yield of Alphonso mango (Mangifera indica 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 i.e. 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).
