Abstract:
A field experiment was carried out at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during rabi 2019-20. The experiment comprising of twelve treatment combinations comprising four sources (Gypsum; Bentonite; SSP and Cosavet) and three levels (20 kg S/ha; 40 kg S/ha and 60 kg S/ha) of sulphur evaluated in Randomized Block Design (RBD) with factorial concept and replicated three times. With regard to the effect of different sources of sulphur on mustard, all growth attributes such as plant height at harvest, number of primary and secondary branches per plant as well as yield and yield attributes viz., number of siliquae per plant, number of seeds per siliqua, length of siliqua, seed yield per plant, seed and stover yield showed significant improvement due to application of gypsum. Among the different sources of sulphur, gypsum fetched the highest net realization and benefit : cost ratio. Significantly higher yield attributes and yields viz., number of siliquae per plant, number of seeds per siliqua, length of siliqua, test weight, seed yield per plant, seed yield and stover yield were recorded with 60 kg S/ha, but statistically at par with 40 kg S/ha except seed yield per plant and seed yield. Application of 60 kg S/ha realized maximum net returns whereas, B:C ratio was maximum with 40 kg S/ha. Among all the possible interaction, treatment combination gypsum x 60 kg S/ha recorded significantly the maximum value of siliquae per plant, seed yield per plant and seed yield. Maximum net realization with a B: C ratio was achieved with the treatment combination of application of gypsum + 60 kg S/ha, followed by application of gypsum + 40 kg S/ha.
