Abstract

A Field experiment was conducted at Cotton Improvement Project, MPKV, Rahuri during Kharif-2022 to find out the optimum plant geometry and nitrogen levels for Cotton hybrid MRC-7938 BG II, with three plant geometries (120 cm × 45 cm, 120 cm x 60 cm and 120 cm × 75 cm) and three nitrogen levels (75, 100, 125 % RDN.). Outcome of this research revealed that the closer spacing (120 cm × 45 cm) had Significantly higher total seed Cotton yield (1784.67 kg ha-1) and No. of Bollsm-2 (67.84m-2) than other plant geometry of 120 cm × 60 cm and 120 cm × 75cm, Even Though yield attributing parameters such as bolls plant-1 (46.30), average boll weight (5.33 gm) and seed Cotton yield per plant (66.51 gm)were statically improved in wider as compared to closer spacing. Higher Nitrogen dose (125% RDN) gave higher average boll weight (5.17 gm), No. of bolls per plant (44.15), No. of bolls per m2 (62.83), seed Cotton yield per plant (65.98 gm) total seed Cotton yield per hectare (1744.22). From the present investigation it can be concluded that the Kharif Bt. Cotton variety MRC-7938 shall be sown at spacing 120 cm × 45 cm and apply nitrogen of 125 % RDN under the Maharashtra conditions for getting higher yields, gross monetary returns and net monetary returns with higher benefit cost ratio under the specific Agro-climatic zone IV b.

Conclusion

From the present investigation it can be concluded that the Kharif Bt. Cotton variety MRC-7938 shall be sown at spacing 120 cm × 45 cm and apply nitrogen of 125 % RDN under Maharashtra conditions for getting higher yields with best use of resources and money
