Abstract:
Two types of hydrogels (Pusa hydrogel and ZEBA hydrogel) were compared with organic (ground nut husk and coconut husk) and inorganic mulches (100 µ black polythene) in Sathgudi sweet orange for soil parameters, physiological, photosynthetic and growth parameters of the leaf. Highest increase in moisture retention (68.26%), change in leaf dry weight was (0.038mg/cm/h) was recorded in plants applied with 70% ER + ZEBA @ 7.5 kg/acre (70 g/plant). Bulk density ranged between 0.71 - 0.79 g/cm3. Maximum (33.20 0C) soil temperature was recorded in the soil of plants mulched with 100 µ black polythene.Stomatal conductance was highest (0.019 mmol/m2/s) in the plants that were applied with 70% ER + Pusa gel @ 2 kg/acre (20 g/plant). Rate of photosynthesis was highest (35.98 µgCO2/m2/s) in plants mulched with 100µ black polythene. Growth parameters did not show much difference among the treatments, but comparatively the trees were larger than the control.
