Potassium and plant growth regulators' influence on pearl millet (Pennisetum glaucum L.) Var. Jaigro 2828: Effects on growth parameters and yield

Abstract

Background: Pearl millet is a suitable substitute for sorghum in areas where it cannot flourish since it can grow in a range of natural settings. Pearl millet outperforms maize and sorghum in terms of heat tolerance and soil moisture uptake. Objectives: Effects of phosphorus and plant growth regulators on growth parameters and yield of pearl millet. Methods: In order to investigate how phosphorus and plant growth regulators affect the development and yield of Pearl millet (Pennisetum glaucum L.) Var. Jaigro 2828, ten treatments (T1–T10) will be included in a randomized block design. The maximum plant height (227.00), plant dry weight (51.57) and yield parameters (ear head length (22.57cm), number of grains/ear head (1989), test weight (6.7g), grain yield (2.77 t/ha), and stover yield (3.80) were produced by phosphorus 50 kg/ha + NAA 50 ppm + Triacontanol 250 ppm, according to the experimental results. Conclusion: Farmers found that the most beneficial combination was Phosphorus 50 kg/ha + NAA 50 ppm + Triacontanol 250 ppm; this produced plants with a height of 227 cm, a dry weight of 51.57 gm, 1989 grains per ear head, 6.7 g test weight, 2.77 ta grain yield, 3.80 ta stover yields, and a Harvest Index of 43.00%, respectively.
