Effect of fertilizer levels on yield, economics and nutrient dynamics in sapota [Manilkara achras (Mill.) Forsberg] cv. Kalipatti

Abstract

The experiment was carried out at Farm of Department of Horticulture, College of Horticulture, Dapoli, Dist. Ratnagiri, Maharashtra during the year 2018 in 40 years old sapota (cv. Kalipatti) orchard to study the effect of fertilizer levels on yield of sapota and nutrient status. The application of treatment T4 i.e. 6 Kg each NPK + 400 Kg FYM Tree⁻¹ Year⁻¹ in three splits i.e., ⅓ in June, ⅓ in September and ⅓ in January resulted in significantly highest yield per hectare (4.09 ton) with maximum net return (Rs. 38605.47/ ha) and B /C ratio (1.23)during experimentation. The significantly highest available N (229.36 Kg/ha) analysed in treatment T3 i.e. 4.5 Kg each NPK+ 300 Kg FYM Tree-1 Year-1 in two splits i.e., ½ in June and ½ in September, and maximum available P and K (59.27 and 581.36 Kg/ha respectively.) were recorded with treatment T4 i.e. 6 Kg each NPK + 400 Kg FYM Tree-1 Year-1 in three splits i.e., ⅓in June, ⅓ in September and ⅓ in January.
