Standardization of Stage Wise Requirement of Nutrients in Sapota

The present investigation was conducted during year 2017-2021 at Agricultural Research Station, Palghar, Dr. B. S. Konkan Krishi Vidyapeeth, Dapoli, to find out the optimum stage wise nutrient requirement of sapota for higher fruit production under north Konkan condition of Maharashtra. Treatment T2 at four different growth stages i.e at vegetative stage in June (20-40-32% NPK), at fruit set in September (20-0-16% NPK), at fruit pea stage in November (20-40-16% NPK) and at fruit growth stage in February (20-0-16% NPK) with application of vermicompost, biofertilizers and micronutrients recorded significantly highest plant canopy volume (125.84m3), number of fruits per tree (1768.31), highest yield per tree (144.89 kg) and per hectare (14.49 t/ha). While, treatment T1 recorded maximum plant height (6.78 m) and average fruit weight (81.44 g) whereas, lowest values recorded in treatment T5 (Control).
