英文摘要	Aim: The study aimed to evaluate the effects of hydrogel application on growth, physiological responses and yield of capsicum under high altitude cold desert conditions with deficit irrigation of Ladakh region. Methodology: Field experiment was conducted with five levels of hydrogel treatment (viz. 0, 5, 10, 15 and 20 kg ha-1) at cold desert Ladakh region with two irrigation intervals (7 and 11 days) during 2014-15 cropping season. Plant growth characters, root morphology, physiological parameters and capsicum yield were analyzed according to standard methods during the experiments. Results: Hydrogel application in deficit irrigation improved physiological parameters viz. leaf chlorophyll content, relative water content, membrane stability index and significant reduction in electrolyte leakage in capsicum plant. Significant improvement in root morphology was also recorded when hydrogel was applied @ 15 and 20 kg ha(-1). Improvement of yield attributing characters as influenced by hydrogel application @ 15 and 20 kg ha(-1) resulted in significant increase in capsicum yield with reduced water requirement. Interpretation: Hydrogel has potential for growth of capsicum crop through improved root morphology and physiology of plant in deficit irrigation under arid and semi-arid regions where availability of water for irrigation is scarce or average rainfall is quite low.
