Effect of Integrated Nutrient Management on Fruit Yield And Quality of Amrapali Mango (Mangifera Indica L.) Under High Density Planting

Abstract

The present study entitled "Effect of Integrated Nutrient Management on Fruit Yield and Quality of Amrapali Mango (Mangifera indica L.) under High Density Planting," was conducted during 2010-11 and 2011-12 at Horticultural Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, Uttar Pradesh-250 110, with a view to study the response of integrated application of organic and inorganic nutrients on vegetative growth, flowering and fruiting attributes in Amrapali mango under western UP conditions. Among the integrated nutrient management treatments applied in the study, maximum plant height, plant spread, number of panicles per plant, fruit set, fruit yield and physic-chemical quality of fruit were recorded with 75% RDF(1000, 500, 1000g NPK + 100 kg FYM/plant) + 20 kg Vermicompost + 250g Azotobacter + 250g PSB/plant followed by 75 o/o RDF + 40 kg Vermicompost + 250g Azotobacter + 250g PS~/plant quring both the years of study. While calculating the economics of different treatments in the present study, the maximum gross income (Rs.1 09041 0 and Rs.1308346 ha-1), net return (Rs.874872 and 1036240 ha-1) and cost: benefit ratio (1 :4.06 and 1:3.81) were registered with 75% RDF(1000, 500, 1000g NPK + 100 kg FYM/plant) + 20 kg Vermicompost + 250g Azotobacter + 250g PSB/plant followed by 75 % RDF + 40 kg Vermicompost + 250g Azotobacter+ 250g PSB/plant. Based on the results obtained from the present study, it may be concluded that, 3/4th of recommended dose of fertilizer in combination with 20 kg Vermicompost + 250g/plant each of Azotobacter and PSB treatment proved to be most effective treatment not only for improving the growth, flowering, fruit yield and quality of Amrapali mango but also registered maximum net return under 75 % RDF + 20 kg Vermicompost + 250g Azotobacter + 250g PSB/plant followed by 75 % RDF + 40 kg Vermicompost + 250g Azotobacter + 250g PSB/plant under high density planting.
