R.3200613A study was conducted at farmer`s field Thondamuthur, Coimbatore district (11°N and 77°E) during (November-April) 1999-2000 in periyanayakkan palayam series, sandy loam soil to study the effect of Controlled Release Fertilizers (CRF) and Water Soluble fertilizers (WSF) as against the conventional Straight fertilizers on chilli yield and quality. The results revealed that the soil application of 50% NPK + WSF (PS at 1 or 2 g L-1) foliar spray found to be the best combination on the basis of cost benefit ratio (1:3.10 and 1:3.00) which had enhanced the green chilli yield (8.86 and 8.94 t ha-1, respectively) and quality viz., capsaicin (4.16 and 4.19 mg 100 g-1), ascorbic acid (92.9 and 93.2 mg 100 g-1), TSS (10.3 and 10.5°B), crude protein (10.3 and 10.5%) and crude fibre (18.6 and 18.8%), respectively as against the NPK control. Hence, the application of 50% NPK plus WSF foliar spray treatment combinations could enhance the production potential of chilli which in turn increases the net return to the farmers.]]>Amans, E.B. and J.H.G.
