Effect of integrated nutrient management (INM) on yield parameters of Brinjal

Abstract

An experiment was conducted at Research Field, Department of Horticulture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, College of Agriculture, Gwalior (M.P.) during rabi season (2016-2017) to see the effect of INM on yield of Brinjal (solanum melongena L.) cv. NDBH-6. Nine treatments of integrated nutrient management viz., 100% RDF (100:60:40 kg/ha) (T1), 100% FYM (20 t/ha) (T2), 100% VC (3 t/ha) (T3), 50% FYM (10 t/ha) + 50 % VC (1.5 t/ha) (T4), 50% RDF (50:30:20 NPK kg/ha) + 50 % VC (1.5 t/ha) (T5), 25% RDF (25:15:10 NPK kg/ha) + 75% VC (2.25 t/ha) (T6), 50% RDF (50:30:20 NPK kg/ha) + 50% FYM(10 t/ha) (T7), 25% RDF (25:15:10 NPK kg/ha) + 50% FYM(10 t/ha) (T8) and control (T9) (no use of fertilizer) were evaluated in Randomized Block Design with three replications with plot sizes of 2 m × 3 m. Significantly higher values of yield attributes such as number of fruits per plant, fruit yield/plant, fruit yield/plot and fruit yield/ha were observed under T7. However, significantly minimum values of yield attributes were observed under control T9 (no use of fertilizer). The economic point of view maximum gross and net return was found with treatment T7. However, the minimum gross and net return was achieved with control T9 (No use of fertilizer) and the highest B:C ratio of 4.24 was obtained with T7. Whereas, the lowest B:C ratio of 1.77 was obtained under control T9 (No use of fertilizer)
