Short duration varieties of cotton lor judicious use of agricultural inputs

摘要

An early maturing strain, HS (CP)-23 developed at Cotton Research bunion HAD, Sirsa when planted with proper practices, offer opportunities for reduction in ihe input cost. The data collected on HS (CP)-23 in comparison with the check H777 revealed that it has short stature, fruiting branch at a low node, first flower opens 10 days earlier, faster flowering rule, shorter boll period, maturily 30 days earlier so us to give almost the same yield as full season H777. Under late sown conditions, this variety has given 20% higher seed cotton yield and 27% higher lint yield as compared to 11777. The carliness provides escape from late season insect damage particularly from pink bollworm. By adopting a short duration strain, HS (CP)- 23 there is a saving of 33. 17 and 20 per cent in interculture, insecticide and irrigation, respectively over the inn. The combined reduction in cost of these agricultural inputs thus increases the producer profits.
