Effect of sulphur, zinc and boron on growth and yield of irrigated Indian mustard (Brassica juncea L) in Bundelkhand region

Abstract

A field experiment was carried out to assess the effect of different levels of sulphur, zinc and boron on growth and yield of Indian mustard (Brassica juncea L) during 2019-20. Results revealed that the growth parameters were maximum with the application of 40 kg S ha-1 at 60 and 90 days after sowing (DAS) and as well as at harvest, which was statistically at par with 20 kg S ha-1 while significantly higher over 0 kg S ha-1. In case of zinc and boron levels maximum value of growth parameters were recorded with 5.0 kg Zn ha-1 at 60 and 90 DAS. The highest seed yield, stover yield, harvest index, oil content and oil yield were recorded with the application of 40 kg S ha-1, which was significantly higher over 0 kg S ha-1. Among zinc and boron levels, the application of 2.5 kg Zn + 0.5 kg B ha-1 produced higher seed yield, stover yield, harvest index, oil content and oil yield. Interactive effect of S, Zn and B on seed yield and oil yield was also found significant. Maximum seed yield was recorded with the application of 40 kg S along with 2.5 kg Zn + 0.5 kg B ha-1 while oil yield was maximum with application of 40 kg S along with 2.5 kg Zn.
