Abstract
The pot experiment comprising 20 treatment combinations was laid out in factorial CRD design with four different sources of sulphur (Cosawet sulphur, Gypsum, Bentonite sulphur and Elemental sulphur) with five levels of sulphur (0, 5, 10, 15, and 20 mg kg-1). Groundnut variety GG-7 was tested in the experiment, in respect of yield, concentration and uptake of micro nutrient (Fe, Mn, Zn and Cu) at different growth stages of groundnut crop and their availability in post harvest soil. The experimental soils were vertic haplustepts medium black calcareous clayey which was slightly alkaline in reaction pH (7.8) and EC (0.58 dSm-1) low available nitrogen (242 kg ha-1) whereas, available phosphorus in medium range (39.20 kg ha-1) and high available potash (336 kg ha-1). The application of elemental sulphur resulted significantly highest yield, micro nutrient content and uptake except Mn in plant at 60 DAS and harvesting stage. Significantly highest micro nutrient concentration and uptake in plant were observed with 20 mg kg-1 (L5) sulphur level. Based on the results obtained from the present investigation, it is concluded that maximum yield of kharif groundnut can be obtained with application of elemental sulphur at 20 mg kg-1 on medium black calcareous soil of South Saurashtra.
