Study of different value added nadep compost for replacing the chemical fertilizers

An attempt was made to explore the possibilities for the use of different harmful weeds, microorganism and other waste materials as a decomposed manure so as to minimize the use of chemical fertilizers in crop production. The experiment was conducted at the Horticultural Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology Meerut (U.P.) to evaluate the economics, viability and feasibility of NADEP compost prepared from different materials. The experiment consisted of eleven different treatments viz. N₁ (Normal NADEP-Control), N₂ (N₁ + 01 Kg. Azotobactor), N₃ (N₁ + 500 gms. Trichoderma), N₄ (Mushroom waste materials), N₅ (N₁ + 01 Kg. compost inoculant), N₆ (Dry cutting of Parthenium), N₇ (Green cutting of Parthenium), N₈ (Dry cutting of Bhang), N₉ (Green cutting of Bhang), N₁₀ (N₁ + 50 Kg. Urea) and N₁₁ (N₁ + 80 Kg. M.O.P.). The economics of NADEP compost was also calculated on the basis of cost of production and labours used. The result obtained from the experiment indicated that the treatment N₄ (Mushroom waste materials) contained highest level of P and K with 1.88% N, than other treatments. The cost of NPK were also worked out as Rs.1.48 Rs./Kg. in same treatment.
