Abstract

An experiment was conducted at Agricultural research station, Adilabad, to assess the effect of harvesting dates on PBW infestation and economy of hybrid cotton and different sowing dates on yield of chickpea. The pooled results indicated that among different harvesting dates viz., 15th November, 15th December, 30th December, 15th January and 30th January during 2018-19 and 2019-20 maximum seed cotton yield (2065 kg/ha) was noticed in 15th December 30th January and 15th November recorded minimum pink bollworm infestation (9.5%), minimum locule damage (8.8) and highest BC ratio (1.78) was noticed on 15th November and found at par with 15th December and 30th December Similarly in Rabi chickpea among different sowing dates viz., 16th November, 16th December, 31st December, 16th January and 31st January the maximum seed yield and highest BC ratio was noticed in 16th November in both varieties JG-14 and NBeG-3 (2250, 2187 kg/ha and 2.59, 2.52, respectively).

Conclusion

From above experiment it was concluded that in cotton-chickpea cropping sequence harvesting of cotton and sowing of succeeding chickpea crop is founded to be most suitable and economical upto 30th December. In this trial, there is no variation of pink bollworm reduction in succeeding cotton crop after chickpea cultivation but in cropping system point of view, cotton followed by chickpea is suitable.
