An experiment was conducted at All India Net work project on Biodiversity and Bio-fertilizers Department of Soil Science, OUAT, Bhubaneswar during kharif season, 2013 to find out the influence of “Integrated nutrient management on of on yield, secondary nutrients content and uptake of bitter gourd” (Momordica charantia L.,) under Bhubaneswar condition. Experimental factors includes T1-Absolute control, T2-50% recommended dose of fertilizers, T3- 50% NPK+ Vermicompost (@2.5 t ha-1), T4 - 50% NPK+ VC+ Bio fertilizers ( Azotobacter, Azospirillum and PSB @ 4kg ha-1), T5-75%NPK, 75%NPK +VC(T6),75%NPK+VC+BF(T7), 100%NPK(T8), 100% NPK+VC(T9), 100%NPK+ VC+BF(T10). Vermicompost (2.5t/ha) and Bio fertilizer mixture were (i.e., Azotobacter, Azospirillum, PSB @ 1:1:1 ratio) applied @ 4kg/ha three times i.e., at the time of sowing, at 30DAS and 45DAS replicated three times in RBD. Among different tratments100% NPK+ Vermicompost+ Bio-fertilizers (Azotobacter, Azospirillum & Phosphate Solubilizing bacteria) (T10) was recorded maximum yield (4036 kg/ha) and yield/plant (1514g/plant). However, same treatment obtained highest Ca concentration (by vine0.82%, than by fruit 0.26%), and uptake of Calcium by shoots (12.7 kg/ha) than by fruit (7.91kg/ha), Magnesium content (by vine 0.80%, by fruit 0.41%). and uptake by shoots (15.4kg/ha) than by fruit (1.47 kg/ha) followed by T7 of the crop.
