Abstract
Status of soil available Sulphur (0.15% Cac12 extractable) in Zonal Research Station, Darisai (Singhbhum) was delineated. Available Sulphur in soils varied from 3.2 to 68.27 mg kg-¹. Considering 10 mg kg-¹ (0.15% CaCl₂ extractable) available sulphur as low. 52 per cent soils were rates to be deficient in Sulphur. Analysis of soils of Darisai reveals to that soils were coarse in textrue (Sandy loam to Sandy Clay), acidic In reaction (pH 4.4 - 5.9) and low to organic carbon content (0.19-073%)
Sulphur is an important essential nutrient for oil seed crops. A field experiment with linseed (Linum usititissimum) was conducted during Rabi season of 1997-98 to study the interaction effect of S (0, 20, 30, 40 kgha-¹) and N (0, 15, 30, 45 kgha-1) on crop yield, content and uptake of nutrient (NPKS) and oil content in grain.
Interaction effect of Nitrogen and Sulphur was significant on grain and straw yields of the crop over control. Significant increase in grain yield was obtained upto 45 kg N and 40 kg S ha-1 level of application. However application of 30 kg N and 30 kg s ha-1 produced the maximum grain yield. Content of oil and in grain decreased with increasing application of Nitrogen increased with Sulphur levels. No further increase in oil content was obtained beyond 30Kg s ha-1 application. Oil yield was highest 30 kg N and 30 kg s ha-1 and followed the same trend as in case of grain yield
Uptake of N and S by Linseed is increased with application of these nutrients. Uptake of P by crop was significant but K uptake was not significant with graded N and S levels. Interaction effect of N and S was significant on yield, oil content and uptake of nutrients (NPKS).
