Effect of post flowering foliar sprays of nutrients for accelerating harvesting of kokum (Garcinia indica Choisy)

Abstract

An investigation was undertaken to find out the effect of post flowering foliar nutrient sprays on harvesting, yield and fruit quality of kokum. The treatments consisted of various concentrations and combinations of urea (1.0%), potassium nitrate (3.0%), monopotassium phosphate (0.5%) and 19 N:19 P:19 K (1.0%). All foliar sprays improved yield and quality of kokum fruits. The treatment T4 (3.0% KNO3 at fruit set and 20 days after fruit set) was the best, which hastened harvesting by 34 days, improved the yield, resulted in maximum harvest before rains, improved acidity, TSS, reducing, non reducing and total sugars and also had the highest B: C ratio. All urea treatments delayed harvesting.
