Abstract
This investigation was Carried out to study the effect of irrigation at different intervals and spraying zinc sulphate at different levels on guar. The experiments were carried out in the Medicinal and Aromatic Plants Section, Dokki during 1993 and 1994. Three intervals of irrigation (one, two and three weeks) and four levels of zinc sulphate as foliar spraying (0,30,50 and 80 ppm) were used. The results showed that there were significant increases in the weight of pods and seeds per plant when the plants were irrigated every week and sprayed with zinc sulphate at the level of 30 ppm. The percentage and yield of guar gum increased when the plants were irrigated every three weeks and sprayed with zinc sulphate at the level of 30 ppm.
