Effect of organic manures on the yield and quality of green chillies (Capsicum annuum L.)

A field experiment was carried out at Eastern Block 37 E, Central Farm Unit of Tamil Nadu Agricultural University, Coimbatore during the kharif season of 2004 to evaluate the effect of organic manures on the yield and quality of green chilli under irrigated condition. The results revealed that application of 100% fertilizer (T(4))recorded the highest green chilli yield (11.78 t/ha) which was followed by organic manure 100% (Composted coir pith 25%+Vermicompost 25%+Biodigested slurry 25%+Azospirillum-PSB 25%) T(3) (11.15 t/ha) and next the best effect was noticed in inorganic 50%+organic 50% (Poultry manure 25%+BDS 25%) T(1) (10.44 t/ha). However, lower fruit yield was recorded in absolute control (T(6)). With respect to quality of green chillies, ascorbic acid, capsaicin, oleoresin and moisture content in green chilli were higher in organic manure 100% (Composted coir pith 25%+Vermicompost 25%+Biodigested slurry 25%+Azospirillum-PSB 25%) T(3) (289.25 mg/100 g, 0.86%, 19.02% and 89.58%, respectively) which was followed by organic manure 100% (FYM 33%+Biocompost 33%+Neem cake 34%) T(2) (282.90 mg/100 g, 0.83%, 18.12% and 86.88%, respectively) and there was no significant variation in the ascorbic acid between T(2), T(4) and T(1), Organic 100% (Composted coir pith 25%+Vermicompost 25%+Biodigested slurry 25%+Azospirillum-PSB 25%) T(3) recorded higher population of bacteria, fungi and actinomycetes after harvest of the crop as compared to other treatments.
