“…It is more pronounced in Alfisols than Vertisols [9]. The results of different investigations indicated that, soils of West Bengal are extensively deficient in sulphur, which is particularly noticeable in coarse-textured lateritic soils and Entisols [15][16][17]. Use of high analysis fertilizers with less or zero sulphur content, reduced or no use of organic manures, followed by crop uptake with high yielding varieties and adsorption of S in acid soils are the major reasons of sulphur deficiency in crop production [18].…”

“…Use of high analysis fertilizers with less or zero sulphur content, reduced or no use of organic manures, followed by crop uptake with high yielding varieties and adsorption of S in acid soils are the major reasons of sulphur deficiency in crop production [18]. Though the efficiency of sulphur is only 8-10% [19], the severity of this deficiency varies according to these regions' physicochemical characteristics of soil as well as the climatic conditions [15,12,20].…”

Sulphur (S) deficiency is widespread in Indian soils, and it has been emerging as a major problem in rice-growing lateritic soils of West Bengal. The vertical distribution of S forms and their relationships with soil physicochemical properties were examined in 50 rice-growing locations of lateritic soils of West Bengal, India, for the current study. For this a total of one hundred fifty representative soil samples were collected from three depths and fifty representative locations of rice-based cropping systems of lateritic belt of West Bengal and analyzed for different fractions of S and important physicochemical properties using standard methodology. Most soils were sandy clay loam to clay loam, with low to medium levels of organic carbon, and strongly acidic to moderately acidic. A decrease in organic carbon across the depths was evident. Among the sulphur forms, organic S was dominant, and the contribution of water-soluble S was least throughout the soil profile. The studied sulphur forms followed the order: total S > organic S > heat soluble S > adsorbed S > sulphate S > water soluble S. Except for adsorbed S, most forms decreased with soil depth. The correlation study revealed that soil pH was positively and significantly correlated with water soluble (r = 0.431**) and sulphate S (r = 0.325*) in surface soils, with sulphate S both in mid-surface (r = 0.450**) and subsurface soils (r = 0.423**). Organic carbon showed a positive correlation with all the S forms throughout the profile. Both clay and silt content positively affected S forms, while sand content showed a negative relationship. Positive correlation among all the S forms observed along soil depth, except for a negative correlation between adsorbed S and sulphate S. This investigation will be helpful for sulphur management to optimize crop yields in lateritic soils.

High temperature and elevated CO 2 under future climate change will in uence the agricultural productivity worldwide. Burgeoning population along with climate change situation is going to threaten the food security of India. According to IPCC 5 th assessment report (2014), global mean surface temperature and concentration of carbon dioxide (CO 2 ) at the end of 21 st century will increase by 4.8°C and 539 ppm respectively under Representative Concentration Pathway (RCP) 8.5 scenario. Considering the burning issue present study aims to nd out the probable change in different climatic parameters under high greenhouse gas emission (RCP 8.5) scenario during 2021-2095 and their impact on wheat yield and water productivity over six locations (Jalpaiguri, Nadia, Murshidabad, Malda, Birbhum and South 24 Parganas) covering ve major agro-climatic zones of West Bengal, a state of eastern India. Results showed that maximum temperature (T max ) and minimum temperature (T min ) will increase by 5.3 o C and 5.9 o C during the end of this century. The increase in annual rainfall will be maximum (22%) at Murshidabad. Wheat yield will increase by 3 to 28% across the study sites. The seasonal crop evapotranspiration value will decline by 1 to 21%. Both water-use e ciency (WUE) and transpiration -use e ciency (TUE) will increase at all the study sites.
