Abstract

The current study, titled "Studies on effect of seed treatments on growth, yield and quality and soil nutrient dynamics of Bt cotton in vertisol," was conducted in 2017-2018 at the Vasantrao Naik Marathwada Krishi Vidyapeeth in Parbhani at the Department of Soil Science and Agricultural Chemistry. The purpose of this research is to examine how nutritional seed treatments affect the development and output of Bt cotton. In the region, shortages in N, P, K, Zn, Cu, Mn, and Fe are present to varying degrees (100.00%, 89.00%, 86.00%, 15.00%, 12.00%, 23.00% and 42.00%, respectively). Due to their abundance among the nutrients, macronutrients may be administered to soil with ease. Cotton producers are hesitant to administer the micronutrients via the soil, though, because of the low application rate and high expense. Furthermore, it is difficult to evenly distribute the little amount of fertilizer on the soil's surface. Growing numbers of experts believe that seed priming is a superior method for improving cotton yields, achieving high seedling vigour, and promoting speedy and uniform emergence. To investigate the impact of nutrient seed treatments on nutrient absorption, Bt cotton quality, and soil nutrient dynamics in vertisol, a field experiment with nine treatments and three replications was conducted. The nutrient seed dressing treatments are T1 – absolute control, T2 - 100% NPK + Zinc Sulphate (ZnSO4), T3 - 100 % N P K + Zn EDTA, T4 - 100% NPK + Borax (B), T5 -100% NPK + Manganese Sulphate (MnSO4), T6 - 100% NPK + Sodium Molybdate (NaMo), T7 - 100% NPK + Copper Nitrate (CuNO3), T8 - 100 % NPK + Ferrous Sulphate (FeSO4), T9 - 100% NPK + Fe EDTA seed application to Bt cotton. The nutrient seed dressing treatment T3 - 100 % NPK + Zn EDTA seed application to Bt cotton found to be effective in improving yield attributing characters like, final plant stand percentages, number of bolls, seed cotton yield, dry matter yield and total biological yield. The highest quality attributing characters like, lint yield, Lint index, ginning percentages and test weight was recorded in the treatment T3 - 100% NPK + Zn EDTA. The fiber quality parameters like upper half mean length, uniformity index, strength, elongity and micronaire value were highest in the treatments T6, T7, T3, T9 and T5 respectively.

Conclusion

The study concluded that applying 100% NPK + Zn EDTA seed to Bt cotton improved yield attributes such as final plant stand, number of bolls, seed cotton yield, dry matter yield, and total biological yield; as well as quality parameters such as test weight, ginning percentage, lint yield; and fiber quality parameters such as upper half mean length, uniformity index, strength, elongation, and micronaire value. As these results are based on one research trial, it is suggested to conduct a few more trials to arrive at a more concrete conclusion.
