Response of Bt Cotton (Gossypium hirsutum L.) to Sulphur application under rainfed conditions

Abstract

A field experiment was carried out at Yavatmal (Maharashtra) India in consecutive years of 2013 to 2015 to study the response of Response of bt cotton (Gossypium hirsutum l.) to sulphur application under rainfed conditions. Eight treatments comprising sulphur application (application of 15, 30, 45kg sulphur through gypsum, 15, 30, 45 kg sulphur through bentonite sulphur and control) were tested. Results indicated that application of 45kg sulphur through gypsum registered significantly higher plant height, bolls/ plant, boll mass, seed index, oil content and yield of seed cotton, uptake of nutrients and registered the higher sulphur use efficiency. Similarly the same treatment recorded higher gross and net monetary returns and benefit: cost ratio.
