Nutrient content in leaves of shoot bearing healthy and malformed panicle under high density mango orchard (Mangifera indica L.) cv amrapali as influenced by organic and inorganic sources of nutrients

A two-year field trial was conducted from 2012–13 and 2013–14 at Horticulture Complex, Maharajpur, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.). Application 520: 160: 450 NPK g plant⁻¹ and Vermicompost (25 kg) + Oil cake (2.5 kg) + Azotobacter + VAM + TV + PSB (100g each) registered higher concentration of N (2.59 and 2.78%), K (62.90 and 77.82 mg kg⁻¹), Zn (27.33 and 230.03mg kg⁻¹), Cu (9.53 and 10.51 mg kg⁻¹), Fe (196.93 and 213.10 mg kg⁻¹) and Mn (88.57 and 98.03 mg kg⁻¹) was in leaves of shoot bearing malformed panicle than healthy once. Whereas, higher concentration of P (0.37 and 0.34%) was in leaves of shoots bearing healthy panicle. Similarly, higher dry accumulation was with malformed panicles over healthy one. The minimum severity and intensity (1.8m² and 9.42%) of malformed panicle was noted when plant nourished with 100% RDF of chemical fertilizer (415: 130: 360 NPK g plant⁻¹) or (2.2m² and 12.15%) organic sources of nutrient (Vermicompost (25 kg) + Oil cake (2.5 kg) + Azotobacter + VAM + TV + PSB (100g each) or its combination registered (1.2m² and 5.56%).
