Effect of micronutrients on growth, yield and fruit quality of mango (Mangifera indica L.) cv. Dashehari

Abstract

The experiment was carried out 2015-16 in Mango orchard at Fruit Research Station Kuthulia, College of Agriculture Rewa (M.P). The study revealed that the Effect of micronutrients on growth, yield and fruit quality of mango (Mangifera Indica L.) cv. Dashehari with 7 treatments in Randomized Block Design with three replications, Observations were recorded on growth yield & quality parameters. The maximum plant height was recorded (9.59m) in Treatment T4, RDF + Foliar spray of 0.4% Zinc sulphate + 0.2% copper sulphate + 0.2% Boric acid (2 Spray at just before flowering and marble stage) followed by (9.03m) treatmentT5, RDF + Zinc sulphate 100 g + Copper sulphate 50 g + Boric acid 50 g (soil application) in basin after harvest + Foliar spray of 0.2% Zinc sulphate + 0.1% Boric acid (2 Spray at just before flowering and marble stage. The maximum plant spread was recorded (Mean of N-S 11.93m E-W 12.87) in treatment T2, RDF + Zinc sulphate 200 g + Copper sulphate 100 g + Boric scid 100 g (soil application) in basin after harvest. The maximum number of fruits per plant was recorded (288.00) in treatment T5, RDF + Zinc sulphate 100 g + Copper sulphate 50 g + Boric acid 50 g (soil application) in basin after harvest + Foliar spray of 0.2% Zinc sulphate + 0.1% Boric acid (2 Spray at just before flowering and marble stage) However the maximum tree volume (1100.79 m3) was recorded in treatment T4, RDF+ Zinc sulphate 0.4%+ Copper sulphate 0.2% + Boric acid 0.2%(2 spray at just before flowering and marble stage). The maximum length and width of fruit were recorded (10.67cm), (5.97cm) in treatment T5, RDF+ Zinc sulphate 100g + Copper sulphate 50g + Boric acid 50g (soil application) + Zinc sulphate 0.2%+ Boric acid 0.1%(2 spray at just before flowering and marble stage). The maximum fruit yield was recorded (64.04kg/tree) in treatment T5, RDF + Zinc sulphate 100 g + Copper sulphate 50 g + Boric acid 50 g (soil application) in basin after harvest + Foliar spray of 0.2% Zinc sulphate + 0.1% Boric acid (2 Spray at just before flowering and marble stage). The minimum fruit yield was recorded (29.55kg)in treatment T7control RDF only. The maximumpulp percentage was recorded (79.94%) in treatment T5, RDF+ Zinc sulphate 100g + Copper sulphate 50g + Boric acid 50g (soil application) + Zinc sulphate 0.2%+ Boric acid 0.1%(2 spray at just before flowering and marble stage) The maximum acidity was recorded (0.26%) in treatment T4, RDF + Foliar spray of 0.4% Zinc sulphate + 0.2% copper sulphate + 0.2% Boric acid (2 Spray at just before flowering and marble stage).The maximum total soluble solids (TSS) was recorded(21.13 0Brix) T5, RDF + Zinc Sulphate 100 g + Copper sulphate 50 g + Boric acid 50 g (soil application) in basin after harvest + Foliar spray of 0.2% Zinc sulphate + 0.1% Boric acid (2 Spray at just before flowering and marble stage).
