Abstract: | In a field study it was observed that sulphur fertilization of chickpea at 100 kg S ha−1 imparted cold tolerance under low temperature stress conditions. Further, foliar sprays of DMSO, H2SO4, KCl and H3BO3 proved effective in alleviating cold injury. Glucose spray also showed efficacy in this regard. The effects of sulphur fertilization and foliar applied DMSO and H2SO4 were largely associated with improved sulphur nutrition of plants, while improvement in K content under KCl treatment and B content under H3BO3 treatment was responsible for cold tolerance effects. Improvement in overall soluble carbohydrate and protein status of plants was held responsible for glucose effects possibly associated with osmoregulation. |
