Neem (Azadirachta indica A. Juss.) is one of alternative species for critical land rehabilitation in dry regions such as Sumbawa, West Nusa Tenggara. Low soil nutrients and water resources are the limiting factors of critical land in dry regions. Enhancement of critical land carrying capacity to support neem growth through the use of organic fertilizer and hydrogel is needed. The research aims to determine the influence of organic fertilizer and hydrogel utilization on neem growth. The study design used a randomized block design with three replications. Research treatments used in the study were organic fertilizer + hydrogel (PH), organic fertilizer (P), hydrogel (H) and control, without organic fertilizer and hydrogel (K). Utilizations of organic fertilizer and hydrogel was able to increase neem growth and survival rate. Compared to control, the diameter and height growth of neem increased up to 1,2 and 1,3 times, respectively. Live percentage of neem as the impact of organic fertilizer and hydrogel utilization was more than 70%. Growth and live percentage enhancement were supported by improvements of soil nutrients (N, P and K), C-organic, CEC, bacterial richness and soil moisture as the impact of organic fertilizer and hydrology treatments.
