Abstract

An experiment laid down to evaluate the effect of biofertilizers, growth regulator gibbralic acid (GA3) and micronutrients on yield and yield attributes of Sapota cv. Kalipatti at Fruit Research Station, Navsari Agricultural University, Gandevi, Gujarat. The treatments of recommended dose of fertilizer (RDF), i.e.100 kg FYM and 1000:500:500 g/plant NPK along with application of biofertilizers (Azospirillum + PSB), growth regulator (GA3) and micronutrients. The pooled results of  75% RDF + biofertilizers- Azospirillum + PSB @ 40 ml/tree + GA3 @ 50 ppm + Grade 4 (micronutrient @ 0.5%) were exhibited significantly higher number of fruit (2815.45), yield (20.61 t/ha)along with net return (Rs. 3,03,951/ha) and Benefit Cost Ratio (2.81). The said application enhanced fruit yield up to 43.41% over control comprising RDF only. However, significantly higher fruit weight (81.34 g) was recorded in application of 100% RDF + biofertilizers- Azospirillum + PSB @ 40ml/tree + GA3 @ 50 ppm + Grade-4 (micronutrient @ 0.5%).
