Sulphur, Zinc and Boron nutrition to improve production efficiency and profitability of Indian mustard in Bundelkhand region

Abstract

 A field experiment was carried out to determine the impact of sulphur (S), zinc (Zn) and boron (B) on growth, 
productivity and profitability of Indian mustard during 2019-20 at Rani Lakshmi Bai Central Agricultural University, 
Jhansi, Uttar Pradesh. The experiment laid out in split plot design with three levels of S as in main plot viz., 0, 20 and 40 
 kg S ha^-1 and six levels of Zn and B viz., control, 2.5 kg Zn, 5.0 kg Zn, 0.5 kg B, 1.0 kg B and 2.5 kg Zn + 0.5 kg B ha^-1 as in 
 sub-plot and replicated thrice. Experimental data revealed that application of 40 kg S ha proved to be more efficient in
 term of growth, yield and economically over 0 kg S ha^-1  as evident by higher CGR during 31-60 DAS (17.6 g m^-2 day^-1 ), 
 seed yield (1.84 t ha^-1 ), net returns (58108 Rs. ha^-1 ), production efficiency (13.49 kg ha^-1 day^-1 ) and profitability (434 Rs.
 ha^-1 day^-1 ). Among Zn and B levels, application of 5 kg Zn ha exhibited highest CGR (17.4 gm^-2 day^-1 ) and RGR (95.1 mg^-2
day^-1 ) during 31-60 DAS and maximum seed yield (1.79 t ha^-1 ), net returns (56709 Rs ha^-1 ), production efficiency 
 (13.18 kg ha^-1 day^-1 ) and protability (423.2 Rs. ha^-1 day^-1 ) were recorded with combined application of 2.5 kg Zn + 0.5 kg 
 B ha^-1 .
