Combined effect of sulphur and boron on yield and yield contributing characters, nutrient and oil content of mustard

Abstract

This experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University, Dhaka during 2014-2015 to know the combined effect of different levels of sulphur (S) and boron (B) on yield and yield contributing characters, nutrient and oil content of mustard and to find out the suitable combination of sulphur (S) and boron (B) for yield maximization of mustard. There were 16 treatment combinations comprising four levels each of S (S₀= 0, S₁=10, S₂= 20 and S₃= 30 kg S ha^-1) and B (B₀= 0, B₁= 1, B₂= 2 and B₃= 3 kg B ha^-1). It was replicated thrice in a randomized complete block design. Results showed that the combination of S and B (20 kg S ha^-1 and 3 kg B ha^-1) contributed positively for better performance of yield contributing characters of mustard. The combination S₂B₃ (20 kg S ha^-1 and 3 kg B ha^-1) produced the highest grain yield (2180 kg ha^-1) followed by S₃B₂ and S₃B₃ treatment combination. The highest protein and oil content of mustard were recorded from S₃B₃ (30 kg S ha^-1 and 3 kg B ha^-1) treatment followed by S₂B₃ treatment combination. Therefore, the combination of S and B (20 kg S ha^-1 and 3 kg B ha^-1) might be suitable dose for cultivation of mustard in tejgaon series soils under agro-ecological zone of 28 (Madhupur Tract) Bangladesh.
