This combined production system is applicable against changing climate, ensuring nutritional requirements along with food security, ecological balance, and economic profitability. The present study explored the performance of cauliflower as lower story crop in aonla based multistoried agroforestry system. The experiment was laid out in randomized complete block design (RCBD) with four replication. The treatments were T 1 = Aonla + carambola + lemon + dragon fruit + cauliflower, T 2 = Aonla + dragon fruit + cauliflower, T 3 = Dragon fruit + cauliflower, T 4 = Cauliflower in the open field (Control). Among different combinations of agroforestry systems, the highest curd yield of cauliflower (15 t ha -1 ) was recorded under dragon fruit-based system (T 3 ) whereas most of the morphological parameters were maximum in the aonla + carambola + lemon + dragon fruit-based system (T 1 ). The highest benefit–cost ratio (2.95) was noted in aonla+dragon+cauliflower-based system (T 2 ) followed by dragon fruit based system (T3), while the highest land equivalent ratio (3.78) was calculated in the aonla + carambola + lemon + dragon fruit- based system (T 1 ). This study revealed that, aonla + dragon + cauliflower based agroforestry system showed relatively higher economic returns and maximum land use efficiency in the upland cropping system.
