Improvement in productivities and profitability in high density orchard of mango (Mangifera indica L) cv. Amrapali through integrated nutrient

A field investigation was conducted to study the effect of organic and inorganic sources of nutrients on productivity and profitability in high density orchard of mango (Mangifera indica L) cv. Amrapali through integrated nutrient at Horticulture Complex, Maharajpur, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.) during 2012–13 and 2013–14. A total of twenty four treatment combinations of inorganic and organic sources on nutrient were tested in factorial randomized block design with three replications. The results of study revealed that higher level of nutrient either in the form of chemical fertilizer or organic sources enhanced the plant growth. Application 520: 160: 450 NPK g plant⁻¹ alongwith vermicompost (25 kg) + Oil cake (2.5 kg) + Azotobacter + VAM + TV + PSB (100g each) registered maximum crown height (78.3cm), crown length (197.4cm), crown width E-W (248.4cm), crown width N-S (251.7cm), shoot length (16.1cm), number of panicle (40.0) and length of panicle (39.7cm). Whereas, higher fruit set pea stage (24.7), fruit retention (17.8%), number of fruit plant⁻¹ (75.5), gross return ( 4.14 plant⁻¹) with B: C ratio (1.94) was noted when plant nourished with 100% RDF of chemical fertilizer (415: 130: 360 NPK g plant⁻¹) incombination with organic sources of nutrient viz. vermicompost (25 kg) + Oil cake (2.5 kg) + Azotobacter + VAM + TV + PSB (100g each).
