Abstract

The experiment was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Faizabad (Uttar Pradesh), during the rabi season of 2008-09 in RBD and replicated three times. The sowing was done on November 20, 2008. The treatments comprised four levels of sulphur (0, 20, 40 and 60 kg S ha−1) and four levels of zinc (0, 5, 7.5 and 10 kg Zn ha−1). The mustard variety “Varuna” was used as test crop. Application of 60 kg S ha−1 and 10 kg Zn ha−1, produced significantly higher plant, primary and secondary branches plant−1, number of leaves plant−1, days taken to flowering, days taken to maturity, number of siliqua plant−1, length of siliqua, and number of seeds siliqua−1, harvest index and oil content. However, dry matte accumulation plant−1, 1000-grain weight (g), biological yield, seed yield, stover yield and protein content significantly increased with increasing dose of sulphur up to 40 kg and zinc 7.5 kg ha−1. The highest benefit cost ratio (1.68) was obtained with treatment combination S40Z7.5. The interaction effect of sulphur and zinc levels on various parameters of mustard was found non-significant.
