Abstract: A field experiment was conducted at Certified Organic Farm of Navsari Agricultural University, Navsari during rabi 2017-18 and 2018-19 to study the effect of different levels of NADEP manures on nutrients content and quality of different crops. The experiment was conducted with five different crops (C1: sorghum, C2: green gram, C3: cabbage, C4: onion, C5: tomato) and three levels of NADEP manures (M1: 100% RDN, M2: 50% RDN, M3: 4t/ha) in FRBD with three replications. Results of the experiment revealed that the higher protein contain was observed in green gram followed by cabbage. Cabbage head and tomato fruit contain higher K, Zn and Cu, and onion bulb and cabbage head contain higher Fe and Mn. Total sugar, reducing and non-reducing content were higher in onion and green gram. Cabbage residues contain higher macro and micronutrient except Fe. However, Fe content was higher in onion residues. As far as manure levels are concerned, its effect on majority parameters of nutritional quality was non-significant except protein, N, Mn and Cu content in economic parts and residues parts of different crops. Treatment receiving higher amount of NADEP compost recorded higher content of these quality parameters as compared to lower levels.
