Effect of Different Crop Residues Mixture, Weed Biomass and Vegetable Waste on Quality of Vermiwash

Abstract

A field experiment was conducted at the Centre for Organic Agriculture Research and Training (COART) Farm, Department of Agronomy, Dr. PDKV. Akola. The chemical and biological properties like pH, EC, N, P, K, Carbon content, Ca, Mg, Na, Cl, SO4, ESP, micronutrient analysis and microbial population were used for analysis quality of vermiwash. It was revealed that, treatment T3 i.e. vegetable waste (70%) + cow dung slurry (30%) was found to be higher in pH (7.78), EC (1.06 dS m-1), carbon content (0.073%) and micro nutrient like Na (79.75 ppm) than the rest of the treatment. Treatment (T1) soybean straw 20% + cow dung slurry 30% recorded significantly highest in NPK content (192.78, 26.78 and 176.72 ppm), Fe (2.35 ppm), Mn (0.64 ppm), Zn (0.74 ppm), Cu (0.44 ppm), Ca (212 ppm), Mg (176.75 ppm), S (176.75 ppm), Cl (20.75 ppm), ESP (49.70), microbial population like fungi, bacteria & actinomycetes (8.50, 230, 3.00 x 104 CFU g-1), GMR (₹ 13639), NMR (₹ 1792) and B:C ratio (1.15) than rest of the treatment, but it was at par with treatment T3 i.e. vegetable waste (70%) + cow dung slurry (30%).
