Status and response of Sulphur and micronutrients in soils of Bihar Plateau for higher crop productivity
... A field experiment conducted for two consecutive kharif seasons, on a limed and unlimed Typic Haplustalf acid soil at Ranchi (Bihar, India), the groundnut pod, oil and straw yields, oil content, and uptake of Ca and S by the crop increased up to 300 kg/ha gypsum and the effect of gypsum was greater in the limed soil (Surendra Singh et al 1996). In a field experiment on sandy loam soil at Dholi, Bihar, groundnuts cv. ...
... This might be due to the availability of S in soil solution through added sulphur and consequent better utilization by groundnut roots. The effectiveness of S sources with respect to S uptake was gypsum> single superphosphate> elemental S. Singh et al. (1996) also reported the superiority of gypsum over single superphosphate and elemental S in groundnut in Alfisols. ...
A field experiment was conducted during the rainy seasons of 1998 and 1999 to evaluate the response of 'ICGS 76' groundnut (Arachis hypogaea L.) to different sources of S, viz single superphosphate, gypsum and elemental sulphur, each at 4 levels (0, 15, 30, 45 kg S/ha). An application of S @ 30 kg/ha proved superior to other levels in respect of yield, protein content and S uptake by groundnut. The effectiveness of S sources was in the order of gypsum > single superphosphate > elemental sulphur. Increasing the levels of S application resulted in narrowing the N : S ratio of groundnut.
