Abstract: A field experiment was conducted during the winter (rabi) season of two consecutive years sandy loam soil using three type crop geometry (45 x 10 cm, 30+60x10 cm and 45x20 cm) three nitrogen levels (0, 40 and 80 kgha^-1) and four antitranspirants treatments (Control, Phenyl mercuric acetate (PMA) @ 250 PPM, Kaoline (6%) and PMA + Kaoline) revealed that plant height, protein content, biological yield, seed yield, stover yield, net returns, benefit: cost ratio significantly higher in paired row spacing of 30+60x10 cm crop geometry but primary and secondary branches plant^-1, dry weight plant^-1, number of siliquae plant^-1, weight of siliquae plant^-1, grain yield plant^-1, 1000-seed weight higher in 45x20 cm plant geometry, WUE and oil content were not affected by different plant geometry. Physiological growth and yield component, quality and quantity of mustard were higher in maximum nitrogen. Application of PMA + Kaoline received higher crop attributes, yields, returns, and quality of Indian mustard but percent of oil content, protein content and soil moisture had not affected by using of different antitranspirants. The higher dose of nitrogen @ 80 kgha^-1 at paired row spacing of 30+60x10 cm with application of combined spray of PMA+Kaoline at 45 and 90 days after sowing increased grain and stover yields maximum economic returns and higher content is Indian mustard.
