Influence of doses and source of sulphur on yield, quality and economics of mustard in red soil of Odisha

Abstract

A field experiment was conducted during rabi season of 2014-15 and 2015-16 at Instructional Farm of KrishiVigyan Kendra , Umerkote, Nabarangpur ,Odisha to study the effect of dose and source of sulphur on its yield ,quality and economics of mustard (Brassica camprestris var. toria ) in red soil of Odisha .The experiment was laid out in randomized block design with three replications .The results revealed that significantly highest oil yield (559.3 kg ha-1 ) was obtained with 60 kg S ha-1 as single superphosphate, which was 115.7 % more in comparison to that of control(259.32 kg ha-1 ) .Similarly application of 45 kg S ha-1 as single superphosphate resulted second highest oil yield (539 kg ha-1 ) with advantage of 107.9 % over control. The oil yield due to application of 45kg and 60 kg S ha -1 as gypsum , 45kg and 60 kg S ha-1 as elemental sulphur were 91.1, 92.9, 67.6 and 86.7 % higher respectively as against the control . The uptake of sulphur with application of 45 kg and 60 kg S ha-1 as SSP, 45 kg and 60 kg S ha-1 as gypsum, 45 kg and 60 kg S ha-1 as elemental sulphur were 101.0, 107.7, 90.9 ,97.0 ,65.1 and 79.0 % higher over control ( 9.89 kg ha-1 ) respectively . Application of 60 kg S ha-1 as SSP resulted significantly highest B: C ratio (2.97) which was 106.3 % higher over control.
