Influence of Sulphur Levels on Productivity and Quality of Varieties of Mustard (Brassica juncea (L.) Czern and Coss)

Abstract:

A field experiment was conducted at Farmers field in Sant Kabir Nagar (Uttar Pradesh) during the rabi of 2019-20. Twelve treatments comprised of four levels of sulphur (0, 20, 40, and 60 kg S ha^-1) and three varieties (Varuna, Vardan and Ashirwad) were arranged in randomized block design with three replication. The soil of experimental field was silty loam in texture slight alkaline in reaction having low organic carbon and available nitrogen and medium in phosphorus and high in potash. The crop recorded normal recommended cultural and plant protection measures. Application of 60 kg S ha^-1 produced significantly higher values of plant, high primary and secondary branches plant^-1, leaf area index, number of siliqua plant^-1, length of siliqua, and number of seeds siliqua^-1, harvest index and oil content. However, dry matter accumulation plant^-1, 1000-seeds weight, biological yield, seed yield, stover yield and protein content was significantly increased with increasing dose of sulphur upto 40 kg ha^-1.
