Description
Summary:Cluster bean guar or (Cyamopsis tetragonoloba L.) a valuable and multipurpose legume, due to its galactomannan and the seeds high in protein, is widely used in different industries. A field study was carried out using factorial experiment in a randomized complete block design with three replications to evaluate the influence of different sowing times (May 15, June 22, and July 27) on performance (seed yield, harvest index, biological yield, etc.), qualitative attributes (galactomannan, protein, carbohydrate, etc.), metabolic traits (lipid, pHenol, fiber, etc.) and yield components (branch/plant, pod/plant and plant height) of 20 guar genotypes (RGC-1066, BR-99, Sarbaz, HG-867, RGC-936, S-5488, S-5490, Dalgan, Iranshahr, Pishen, RGC-1038, RGC-1017, S-5498, RGC-1031, Saravan, S-5499, RGC-986, RGC-1003, HG-884 and HG-563) from three different origins (India, Iran and Pakistan). According to the ANOVA results, plant height, harvest index, the number of pod/plant, total chlorophyll, carbohydrate rate, gum content, and gum yield were significantly changed (p
