Abstract:
A study was conducted at Agronomy Research Field, College of Agriculture, Gwalior (M.P.) during rabi seasons of 2018-19 and 2019-20. The soil of the experimental field was alluvial and sandy clay loam in texture. Twenty four treatment combinations administered in mustard consisted of 4 sulphur levels (0, 20, 40 & 60 kg ha^-1), three Zn levels (0, 2.5 & 5 kg ha^-1) and two zinc solubilizing bacteria levels (without zinc solubilizer & with zinc solubilizer) were replicated three times in randomized block design (factorial).Higher value of growth parameters (like; number of leaves plant^-1and number of secondary branches plant^-1), yield attributes (viz.; number of seeds silliquae^-1and seed yield plant^-1), physiological characteristics (viz.; LAI and AGR) as well as computed parameters (viz.; seed and stover yield) and net return were recorded significantly under 60 kg ha^-1 S level, which was statistically at par with 40 kg ha^-1 S level; while lower value was noted under 0 kg ha^-1 S level. Maximum value of various parameters were recorded under 5 kg ha^-1 Zn level, which was statistically at par with 2.5 kg ha^-1 Zn level; while significantly minimum value was noted under 0 kg ha^-1 Zn level. Significantly superior value of different attributes was noted with zinc solubilizer; while minimum value was recorded without zinc solubilizer. In case of net return; significantly higher net return was noted under 40 kg ha^-1 S level + 5 kg ha^-1 Zn level (Rs.51674 ha^-1), which was statistically at par with 60 kg ha^-1 S level + 5 kg ha^-1 Zn level (Rs.51654 ha^-1); while lower value was recorded under 0 kg ha^-1 S level + 0 kg ha^-1 Zn level (Rs.38968 ha^-1).
