Effect of Mulching and Sulphur on Growth and Yield of Yellow Mustard (Sinapis alba)

This study was conducted at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P) in Rabi, 2021 to study the Effect of Mulching and Sulphur on Growth and Yield of Yellow Mustard (Sinapis alba). It was consisting of combination of three types of Mulching No mulch, Paddy straw and Poly sheet mulch and three Sulphur levels (20kg S/ha, 40 kg S/ha and 60 kg S/ha). The study was laid out in Randomized Block Design with nine treatments each replicated thrice. The experimental results revealed that the growth parameters and yield parameters such as plant height (145.94 cm), dry weight (34.30 g), number of branches/plant (11.58), number of seeds/siliquae (37.41) and test weight (3.08 g) at harvest, significantly recorded in treatment T9 with the application of Poly sheet mulch+60 kg S/ha. Moreover, seed yield (1.82 t/ha), stover yield (3.94 t/ha), gross return (95,762.64 INR/ha), net return (52,487.44 INR/ha) and B:C ratio (2.21) were also recorded significantly higher in the treatment which is Poly sheet mulch + Sulphur 60 kg/ha among all treatments.
