RESPONSE OF SILICON AND MICRO NUTRIENTS ON FRUIT CHARACTER AND NUTRIENT CONTENT IN LEAF OF SAPOTA

ABSTRACT

Experiment was conducted to know the response of nutrients on fruit character and its influence on enhancing yield and quality and also on accumulation of nutrients in leaf. Potassium silicate, calcium silicate was taken as silicon source and solubor as boron and kiecite-G were used as micronutrient source. Fruit characters like fruit weight (99.96 g), fruit length (5.55 g), fruit diameter (5.85 g), volume of fruit (102.38 g) and maximum shelf life (10.90 days) was recorded with treatment supplemented with foliar application of potassium silicate at 8 ml per litre. Highest yield per tree (124.81 kg) and hectare (12.48 t) were recorded in treatment supplemented with foliar application of potassium silicate at 8 ml per litre where as highest B:C ratio (2.36) was recorded in treatment which is supplied calcium silicate as soil application. The highest nutrients like nitrogen (1.583 %), phosphorous (0.175 %), potassium (1.20 %) and silicon content (1.20 %) in leaf were recorded with potassium silicate spray (8 ml per litre).
