Abstract

A field experiment was conducted in a sandy loam soil at Agricultural Research Station farm, Bhavamsagar, Tamil Nadu, during (Dec-June) 1999-2000 to study the effect of plant growth regulators on yield, quality, available soil nutrients and uptake of nutrients by chilli ev. Col. The results of the investigation revealed that foliar application of vipul 0.1 per cent EC at 300 ml ha for three times at 25, 45 and 65 days after transplanting maximized the dry pod yield of chillies (3.08 t ha'), improved the quality attributes (capsaicin, total soluble solids and ascorbic acid contents) and enhanced the uptake of major nutrients (N, P and K). Miraculan 0.05 per cent EC at 300 ml ha also had a favourable influence on dry pod yield and total soluble solid content of the red ripe fruits.
