An experiment was conducted during 2018 - 2020 to assess the impact of drip trickle irrigation intervals viz. 3 and 6 day water supply and different dose of hydrogel viz. 30, 60, 90 and 120 g of soil application with black polyethylene mulch on soil properties, growth, yield and fruit quality attributes in Kinnow mandarin (Citrus reticulate Blanco). The combination treatment of drip trickle ir rigation intervals and hydrogel with mulch recorded the maximum moisture percentage followed by sole hydrogel and drip trickle irrigation intervals. The three days intervals water supply through drip trickle irrigation and 90 g hydrogel with mulch recorded favourable results with regards to soil moisture and physico -chemical characteristics of the soil. Three days drip trickle irrigation and 90 g hydrogel with mulch were found to be most effective in producing maximum vegetative growth than rest of the trea tments. Plant treated with three days drip trickle irrigation and 90 g hydrogel with mulch recorded maximum yield (9290.76 and 9518.72 kg ha -1), followed by three days drip trickle irrigation and 120 g hydrogel with mulch (8973.84 and 9212.92 kg ha-1) while minimum in control plant (5615.60 and 5924.18 kg ha-1) under two year experimentation. Hydrogel retain water and nutrients, when release to the plants surrounding soil near root zone of starts to dry up and black polyethylene mulch is poor aeration and non-decomposable nature. The improving yield due to fact that soil was wet for a longer time in summer season for improving soil moisture levels and fruit quality in subtropical ecosystem.
