Abstract:
Sulphur (S) is an essential nutrient required by mustard crop for its vegetative as well as reproductive growth. It is an important component of various amino acids, proteins and responsible for quality of oil in oil crops. There are estimates that around 41% of Indian topsoil is low in S content. An experiment was carried out at the agricultural research farm of Lovely Professional University, Punjab during the Rabi season of year 2021-2022. The experiment comprising two varieties (PBR357 and RLC3) and five levels of S (control, 15, 30, 45 and 60 kg/ha S), was conducted in two factorial randomized block design replicated thrice. Results showed that both growth and yield of mustard differed significantly with different varieties and S levels. Plant height, number of leaves per plant, number of siliqua per plant, number of seeds per siliqua, grain yield, straw yield, test weight and S content in grains were significantly more in PBR357 as compared to RLC3. In terms of levels of S, application of 60 kg/ha found to be significantly superior over the control, 15 and 30 kg/ha in increasing all the above parameters. Vigorous and high yielding varieties of mustard along with application of optimum amount of S fertilizer can be used to obtain higher yield of mustard crop.
