Response of micronutrient on the quality yield of mango cv. Alphonso under Konkan agro-climatic conditions

Abstract

The present study was aimed to determine the effect of micronutrients (Cu, B and Zn) on the quality of mango (Mangifera indica L.) cv. Alphonso plants. For this purpose, full bearing and mature (10 years old) trees were selected for micronutrient application of different combinations of CuSO4, borax, boric acid and ZnSO4 before flowering and at marble stage of fruit. Results revealed that the application of all micronutrients significantly increased the quality of fruit than the control. Results reported that the treatment T5 (RDF + foliar spray of 0.4% zinc sulphate + copper sulphate (0.2%) + Borax (0.2%), spraying at just before flowering and marble stage of fruit growth recorded the highest number of fruits/tree (173.32) and fruit yield (4.14 t./ha). Further, the treatment T4 (RDF + foliar spray of 0.4% zinc sulphate + boric acid (0.2%) spraying at just before flowering and marble stage of fruit growth recorded the highest T.S.S (18.80 0B) and lowest acidity (0.20%).
