Studies on response of sulphur, zinc and boron levels on yield, economics and nutrients uptake of mustard [Brassica juncea (L.) Czern & Coss.]

A field experiment was conducted during rabi season of 2008-09 and 2009-10 at the Students’ Instructional Farm, Chandra Shekhar Azad University of Agriculture & Technology, Kanpur to evaluate the effect of sulphur (0, 20, 40 and 60 kg S/ha), zinc (0, 5 and 10 kg Zn/ha) and boron (0, 0.5 and 1.0 kg B/ha) levels on quality, economics and uptake of nutrients in mustard [Brassica juncea (L.) Czern & Coss]. Results revealed that application of 60 kg S/ha gave significantly higher seed yield, economics, oil yield, protein yield and nutrients uptake (kg/ha) than control, 20 and 40 kg S/ha during experimental years. The application of 10 kg Zn/ha produced maximum seed yield, net return, B : C ratio, oil yield, protein yield and nutrients uptake of mustard. The application of 1.0 kg B/ha significantly increased seed yield, economics, oil yield, protein yield and nutrients uptake (kg/ha) of mustard over control and 0.5 kg B/ha. On economic basis, the highest profit was recorded with carbined use of 60 kg S/ha+5 kg Zn/ha and 1.0 kg B/ha.
