Abstract

Crop yield and quality may differ with nutrient management and moisture conservation. Popular public sector intra hirsutum cotton hybrid NHH 44 converted in transgenic version is made available to farmers. Hence, it was necessary to optimize the fertilizer requirement for its higher seed cotton yield and better fiber properties. Hence, a field trial was conducted at Cotton Research Station, Nanded (Maharashtra, India) during kharif 2019-20 and 2020-21 seasons to study the effect of moisture conservation techniques and fertilizer levels on yield and quality of Bt cotton hybrid NHH 44 (BG II) under rainfed condition. The experiment was conducted on vertisol in split plot design with three replications. Moisture conservation practices included in main plot were control i.e. M1 - flat bed; M2 - opening furrow at 60 DAS; M3 - application of superabsorbent @ 12.5 kg ha-1 and M4 - broad bed and furrow. The sub plot treatments were consisted with four fertilizer (NPK) levels viz., F1 - 80:40:4

Keywords

Seed cotton yield, fiber quality, bolls m-2, lint yield, oil yield.

Conclusion

Sowing of Bt cotton hybrid on broad bed and furrow was found to increase seed cotton yield, lint yield and oil yield over control and application of superabsorbent. The fertilizer level of 120:60:60 NPK kg ha-1 was found optimum for Bt cotton hybrid under rainfed condition.
