Abstract:

A field experiment was conducted at Department of Agronomy, Agricultural College, UAS, Raichur during Kharif season of 2016-17 and 2017-8 to know the effect of planting geometry, fertilizer levels along with growth retardant spray on seed cotton yield and economics of cotton grown under HDPS in irrigated condition. The experiment was laid out in split plot design consisting of three levels of planting geometries viz., S1: 60 cm x 10 cm (1,66,666 plants ha-1), S2: 75 cm x 10 cm (1,33,333 plants ha-1) and S3: 90 cm x 10 cm (1,11,111 plants ha-1) in main plots and six levels of management practices viz., M1: 60:30:30 N:P2O5:K2O kg ha-1 M2: 80:40:40 N:P2O5:K2O kg ha-1, M3: 100:50:50 N:P2O5:K2O kg ha-1, M4: M1 + mepiqnat chloride @ 250 ppm sprayed at 60 DAS, M5: M2 + mepiquat chloride @ 250 ppm sprayed at 60 DAS and M6: M3 + mepiquat chloride @ 250 ppm sprayed at 60 DAS in sub plots. The result revealed that the closer row spacing of 60 cm x 10 cm produced significantly higher seed cotton yield (2875 kg ha-1) over other planting geometries and significantly lower seed cotton yield (2388 kg ha-1) was recorded under wider row spacing of 90 cm x 10. Among different fertilizer levels, application of 100:50:50 N:P2O5:K2O kg ha-1 + mepiquat chloride @ 250 ppm sprayed at 60 DAS recoded significantly higher seed cotton yield (2915 kg ha-1) and lower was recorded with the application of 60:30:30 N:P2O5:K2O kg ha-1 (2392 kg ha-1). In case of economics, row spacing of 60 cm x 10 cm and 75 cm x 10 cm recorded significantly higher net returns (₹ 78,121 ha-1 and ₹ 71,857 ha-1, respectively) and BC ratio (2.57 and 2.48, respectively). Among fertilizer levels, application of 100:50:50 N:P2O5:K2O kg ha-1 + mepiquat chloride @ 250 ppm sprayed at 60 DAS recoded higher net returns (₹ 79,870 ha-1) and BC ratio (2.60) while significantly lower was observed with the application of 60:30:30 N:P2O5:K2O kg ha-1 (₹ 58,986 and 2.25, respectively).
