Abstract

The field experiment was conducted during Kharif 2020 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.). The soil of trial plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low organic carbon (0.36%), medium availability N (171.48 kg ha-1), lower availability P (15.2 kg ha-1) and medium availability K (232.5 kg ha-1). The research was laid out in Randomized Block Design (RBD) which consist of ten treatments which are replicated thrice to Study the different levels of potassium and sulphur on growth and yield of Pearl millet. The results showed that higher plant height (150.43 cm), maximum number of leaves per plant (9.13) and highest dry weight per plant (19.55 g) were obtained significantly with the application of 50 kg ha-1 of K+20 kg ha-1 of S as compared to all other treatments. The higher grain yield (3.97 t/ha) and stover yield (7.68 t/ha) and were significantly recorded with the application of 50 kg ha-1 of potassium +20 kg ha-1 of s

Pearl millet, Potassium, Sulphur, yield.

Conclusion

Study suggests that to achieve maximum plant height (150.3 cm), dry weight/plant (19.55 g), grain yield (3.97 t/ha) and stover yield (7.68 t/ha) was significantly recorded with the application of potassium (K) 50 kg ha-1 + sulphur (S) 20 kg ha-1. Hence, the application of Potassium (K) 50 kg ha-1 + Sulphur (S) 20 kg ha-1 is beneficial for pearl millet production under eastern Uttar Pradesh condition.
