Abstract
Field experiments were conducted during 2012 ‐ 2013 on clay loam soil at Vallampadugai, Chidambaram, Cuddalore district, Tamil Nadu, India, to evaluate the efficacy of vermifertilizer (VF) on the soil qualit y characteristics, and on the yield and quality characteristics of chilli ‐ Capsicum annuum L., in comparision to inorganic fertilizers (NPK). VF (5 tons/ha) and VF supplement ed with recommended dose of inorganic fertilizer (RDCF) (120:60:30 kg.ha) (w/w) had significantly (P<0.05) increased the pore space, water holding capacity, c ation exchange capacity, organic carbon, available N, P, K, other micro-macro nutrie nts ‐ Ca, Mg, Na, Fe, Mn, Zn, Cu and microbial population - activity and humic acid content, reduced particle and bulk density, pH, EC in the field soil. Also the yield ( both fresh and dry fruit weight) and quality (vitamin A, Vitamin C and Capsaicin content ) of chilli was enhanced in the soil. On the contrary, the application of NPK alone has resulted in reduced porosity, compaction of soil, organic carbon, microbial popul ation, microbial activity and humic acid content. In over all investigations, the obtained results specified that the combined application of VF and RDCF show promising results in the cultivation of chilli and better for obtaining the higher quality chilli and further the VF reduce 50% RDCF to the chilli crop and also enhances soil qual ity, yield and quality characteristics of chilli than 100% application of RDCF on chilli.
