Abstract
A field experiment entitled “Effect of sulphur rates and sources on mustard (Brassica
juncea L.) productivity and soil health” conducted during rabi season of 2020-21 at Integrated
Farming System (IFS) unit of Banda university of agriculture and technology, Banda. The
experiment was comprises of seven treatments and four replications and laid out under RBD. Three
different levels of sulphur (15, 30 & 45 kg ha-1
) and two sources viz. elemental sulphur and 80%
WDG were tested on mustard variety NRCHB-101. The results revealed that both the sources of
sulphur were found comparable and statistically at par with each other. Growth attributes like plant
height, dry matter accumulation and number of branches plant-1 were increased significantly with
the increase of sulphur levels up to 45 kg S ha-1
irrespective of sources of sulphur. When compare
the levels of sulphur (15, 30 & 45) with each other data revealed that 30 kg S ha-1 was significantly
superior over 15 kg S ha-1
but it was at par with 45 kg S ha-1
i.e. further increase in sulphur levels
from 30 to 45 could not achieve the level of significance. Yield attributes like number of siliqua
plant-1
, number of seeds siliqua-1
, and 1000 seed weight increased significantly with the increase of
sulphur doses and up to 30 kg S ha-1
significant response was recorded because 45 kg S ha-1 was at
par with 30 kg S ha-1
.
Effect of sulphur doses and sources on seed, stover and biological yields were also studied.
Best treatment T3 (30 kg elemental S ha-1
) gave 2075 kg ha-1
seed yield over the control. Seed yield
obtain under T3 was 458 kg and 22.07 % more over control. Sulphur concentration in seed (0.81)
and stover (0.50) and total uptake of sulphur (43.88 kg ha-1
) was significantly best in treatment T3
followed by T6. Review of data related to economic studies showed higher gross return (Rs/ha
96488), net return (Rs/ha 58109), B:C ratio (2.51) and VCR (1.51) were found in treatment T3
followed by treatment T6. Effect of applied treatment on soil fertility status of soil pH, EC, organic
carbon, available N, available P and exchangeable K were non-significant. The sulphur content in
soil increase with increasing levels of sulphur and highest (18.01 mg kg-1 soil) sulphur content was
noticed in treatment T4. Overall application of 30 kg S ha-1
irrespective of sources was found to be
optimum dose for sulphur management in the mustard crop to the farmers of this region.
