Performance of Different Levels of NADEP Manure on Nutrient Contents and Quality of Different Organically Grown Crops

A field experiment was conducted at the certified organic farm of Navsari Agricultural University, Navsari Gujarat, during rabi 2018-19 years to study the effect of different levels of NADEP manures on nutrient content and quality of different crops. NADEP is the method of organic composting uses a wide range of organic materials such as crop residues, weeds, forest litter and kitchen waste with an end product of a fertilizer that serves as a good alternative to farmyard manure. The experiment was conducted with five different crops (C₁: Maize, C₂: Indian bean, C₃: Cauliflower, C₄: Garlic, C₅: Carrot) and three levels of NADEP manures (M₁: 100 % RDN, M₂: 50 % RDN, M₃: 4/ha) in FRBD with three replications. Results indicated that the interaction effect of M₁C₄ recorded significantly maximum P (%) as well as M₁C₃ recorded significantly maximum K (%). Indian bean recorded significantly higher protein and N which was found at par with Garlic. Cauliflower recorded significantly higher nutrients like K, Mn, Zn and Cu whereas Carrot recorded significantly higher Fe and reducing sugar. Maize recorded higher total sugar and non-reducing sugar in economic parts of different crops. Economic produce of crops was found nutritionally rich under the treatment of 100 % RDN applied through NADEP compost. In the case of different crop residue parts, significantly higher content of P, Fe, Mn, and Cu was recorded in Cauliflower whereas significantly maximum Zn was recorded in Maize. Significantly maximum K and maximum N were recorded in the Indian bean which was observed at par with Cauliflower. The interaction effect was found non-significant for different crop residue parts.
