Czern and Cosson.] varieties under irrigated condition. M. Sc. (Ag.) Thesis, Department of Agronomy, Institute of Agricultural Sciences, BHU, Varanasi.http://krishikosh.egranth.ac.in/handle/1/96131The present field experiment entitled “Effect of levels and sources of sulphur on growth, yield and nutrient removal of Indian mustard [Brassica juncea (L.) Czern. and Cosson.] varieties under irrigated condition was carried out at Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during winter (rabi) season of 2014-15. The experiment was carried out with three mustard varieties viz. ‘Maya,’ ‘Giriraj’ and ‘NRCHB-506’ three levels of sulphur (0 kg S, 30 kg S and 60 kg S ha-1) and two sources of sulphur Elemental sulphur (80% WDG) and Bentonite sulphur (90% G ) was laid out in a split-split plot design with three replications. Growth and yield attributes and yield viz. plant height (cm), dry matter production, number of branches plant-1, number of green leaves plant-1, leaf- area index, number of siliquae plant-1, siliquae per main shoot, siliqua length, seeds siliqua-1, 1000-seed weight, seed yield (kg ha-1), stover yield (kg ha-1) and harvest index (%), quality parameters viz. seed oil content (%) and nutrient removal (N, P and S) by seed and stover (kg ha-1) were recorded and finally the comparative economics of various treatments was computed. The maximum values of growth as well as yield parameters and yield of Indian mustard crop were recorded with the variety ‘Giriraj’. Marked improvement in growth and yield traits and seed yield of mustard were observed due to increasing level of sulphur up to 60 kg ha-1. However, application of 30 kg S ha-1 exhibited appreciable improvement in growth and yield attributes as well as seed yield of Indian mustard. Application of sulphur through elemental sulphur was found to increased the yield of mustard, removal of sulphur and improve the quality traits viz. oil and seed protein content. Based on the experimental findings it is recommended that Indian mustard variety ‘Giriraj’ with no sulphur proved that most remunerative for achieving higher monetary return in eastern Uttar Pradesh under irrigation condition.enThesis
