Effect of sulfur nutrition on biochemical parameters in developing chickpea (Cicer arietinum L.) seeds

Field trials were conducted by supplementing soil with three sulfur sources viz; gypsum (GYP), single superphosphate (SSP) and elemental sulfur (ES) at 20 and 40 Kg/ha as conventional means for providing sulfur nutrition to study the biochemical parameters during seed development of chickpea cultivars (PBG1 and BG1053). The biomass content, seed sulfur and sulfur containing amino acids (methionine and cysteine), the biochemical parameters responsible for seed protein quality, maximally increased during cell enlargement phase (22 to 32 DAF) with GYP followed by SSP and ES at 40 Kg/ha as indicated by decline in the nitrogen to sulfur ratio.
