Effect of Different Sources of Sulphur on Growth, Productivity and Oil Content of Brassica campestris var. toria in the Red Soil of Odisha
Abstract:
A field experiment of two years was conducted during the rabi seasons of 2014-15 and 2015-16 at Instructional Farm of Krishi Vigyan Kendra (Nabarangpur), Umerkote, Nabarangpur, Odisha, India to study the effect of different sources with the graded doses of sulphur on growth, productivity and the oil content of Mustard (Brassica camprestris var. toria). The experiment was laid out in the randomized block design with three replications and nine treatments viz; T1 30 kg S ha-1 as SSP, T2 45 kg S ha-1 as SSP, T3 60 kg S ha-1 as SSP, T4 30 kg S ha-1 as Gypsum, T5 45 kg S ha-1 as Gypsum, T6 60 kg S ha-1 as Gypsum, T7 30 kg S ha-1 as Elemental sulphur, T8 45 kg S ha-1 as Elemental sulphur, T9 60 kg S ha-1 as Elemental sulphur along with an untreated control. Significantly highest seed yield (12. 47 qha-1) resulted under the application of sulphur @ 60 kgha-1 as Single Super Phosphate (SSP ) due to the significant increment in the yield attributes studied when compared to control (7.15 q ha-1). The sulphur application @ 45 kgha-1 as SSP which had given the seed yield 12.47 q ha-1 was at par with the seed yield of sulphur application @ 60 kgha-1 as SSP. Yield advantages due to the application of Gypsum @ 45 kgha-1, 60 kgha-1 and Elemental sulphur 45 kgha-1, 60 kgha-1 were 60.69%, 62.09% and 47.13%, 57.90%, respectively over control (7.15 q ha-1). The oil content in the seed was highest with the application of sulphur @ 60 kgha-1 (44.62%). The oil content of mustard was almost at par with both the sources of sulphur viz; SSP and Gypsum.
