The field experiment and laboratory experiment was conducted in Split Plot Design with three replications during 2011-12 & 2012-13 on Indian mustard variety Urvashi at New Dairy Farm, Kalyanpur, Kanpur and Seed Testing Laboratory of Department of Seed Science and Technology, respectively. Six doses of zinc and sulphur viz. 0.0, 2.5, 5.0, 7.5, 10.0, 12.5 Kg ha -1 and 0, 10, 20, 30, 40, 50 Kg ha -1 , respectively were applied as basal dose. Observations were recorded on interaction effect of seed yield and seed quality parameters. Results showed that the application of zinc and sulphur affected significantly to all parameters. The interaction zinc and sulphur did not show significant effect on days to 50% flowering, number of siliquae plant -1 , number of seeds siliqua -1 , days taken to maturity, raw seed yield Kg plot -1 , graded seed yield Kg plot -1 , raw seed yield Kg ha -1 , graded seed yield Kg ha -1 , 1000-seed weight. However, rest of the characters was affected by the application of zinc and sulphur. Keywords: Mustard, zinc, sulphur, effect, seed yield, interaction Introduction Mustard (Brassica juncea (L.) Czern and Coss) is important Rabi oilseed crop which belongs to family “Cruciferae. In India, first rank in area and third in production after China and Canada. On the world map, Indian rapeseed and mustard occupies about 6.18 million hectare area with a production of 7.36 mt and average productivity of 1190 kg/ha. In India Rajasthan ranks first both in area in production. Gujarat state has the highest productivity of rapessed and mustard, Whereas in UP repressed and mustard is grown on 6.58 lakh. ha area with production of 0.76 mt and productivity of 1155kg/ha (Anonymous 2015) [1] . In India consumption of oil and fats is continuously increasing due to increase in population at an annual growth rate of 2.1 per cent and improved standards of living due to accelerated economic development in the base scenario of per capita growing by 4.0 per cent annually, an average Indian’s yearly edible oil requirement in fated to rise from 9. 81 kg in 1999-2000 to 16 kg by 2015 (Hegde, 2004) [10] . For oil seeds sulphur and zinc are vital nutrients for growth and development. Sulphur in considered to be the fourth important essential nutrient after nitrogen, phosphorus and potassium for the plant growth. Sulphur performs many physiological functions like synthesis of cysteine, methionine, chlorophyll and oil content of oil seed crops. It is also responsible for synthesis of certain vitamins (B, Biotin and Thiamine), metabolism of carbohydrates, proteins and oil formation of flavor compounds in crucifers. Keeping this in view, the present investigation was carried out to study the effect of sulphur, zinc and FYM on growth, yield attributes, seed yield, gross income, net profit and B:C ratio in irrigated Indian mustard. In recent years, sulphur deficiency has been aggravated in the due to continuous removal by crops and use of high analysis sulphur devoid fertilizers coupled with intensive cropping with high yielding varieties and reduction in use of organic manure and sulphur containing fungicides and insecticides resulted in sulphur deficiency in soils (Pasricha et al., 1972) Sulphur deficiency is as high as 81 per cent in the light textured soils of North and North West zone of Gujarat (Sadasania, 1992) [13] . They reported that sulphur deficiency tends to affect adversely on growth and which reduces the crop yield to the extent of 10-30 per cent. Material and Method The experiment was conducted at the New Dairy Research Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kalyanpur,
