A field experiment was conducted during rabi 2019-2020 at forest nursery of College of Forestry SHUATS, Prayagraj, Uttar Pradesh to find out the effects of hydrogel and inorganic manure on growth and yield of lettuce (Lactuca sativa L) under citrus-based agroforestry system. The experiment was laid out in RBD with hydrogel and inorganic manure constituting 13 treatments combinations. The investigations revealed that the treatment comprising hydrogel 2.5 kg + N 90 kg + P 75 kg + K 75 kg/ha recorded significantly higher values for survival percentage (87.80%), dry weight/plant (20.80 g), fresh weight/plant (144.90 g), leaf weight/plot (498.10 g) and B-C ratio (1:1.87). In case of other plant parameters it was also superior to others thoug at par with some of the treatments. Hence reatment comprising hydrogel 2.5 kg + N 90 kg + P 75 kg + K 75 kg/ha was best for higher growth rate of lettuce.
