Interaction Effect of Sulphur and NPK on Growth Parameters and Yield of Mustard

Abstract

The field experiment conducted at Rajaula Agriculture Farm of Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya Chitrakoot, Satna (M.P.) during the Rabi season of 2021-22 aimed to study the effect of sulphur (S) and NPK (nitrogen, phosphorus, and potassium) on the growth parameters, yield components, and yield of chickpea. The experiment consisted of 12 treatment combinations arranged in a randomized block design with three replications. The mustard variety Pitambari was grown using recommended agronomic practices. Based on the results obtained from the investigation, it was observed that the application of S at a rate of 40 kg ha-1 in combination with 125% of the recommended dose of fertilizers (RDF) had a significant impact on various growth parameters. The treatment with S at 40 kg ha-1 + 125% RDF resulted in the highest values for plant height (198.4 cm), number of leaves (36.9), and number of branches (13.2) at 90 days. Furthermore, this treatment also showed the highest values for yield attributing characters, including the number of siliqua per plant (327.7), number of seeds per siliqua (12.1), and seed index (6.9 gm). The maximum seed yield of 11.53 quintals per hectare (q ha-1) was also obtained with the application of S at 40 kg ha-1 + 125% RDF.
