## Abstract
Background and Objective: Land productivity can be increased by optimizing land use and applying environmentally friendly technologies to achieve sustainable agriculture and one of them is intercropping. This study aims to analyze the growth and production of maize in the tropics of Indonesia's humid regions that utilize space under the coconut canopy. Materials and Methods: This study was carried out using a Randomized Block Design (RBD) where the treatment was given the combination of packages. The condition of the shade as the main plot consists of 3 levels namely; K0: Without coconut plants, K1: Shade of coconut plants aged 10-15 years and K2: Coconut plants >15 years. Plots were maize varieties namely; V1: Composite and V2: Hybrid. While plot children are fertilizing carried out in 3 stages, namely; F1: Fertilizing 100 kg urea haG 1 +200 kg NPK, F2: 150 kg urea+300 kg NPK and F3: 200 kg urea haG 1 +100 kg TSP/SP 36 haG 1 +50 kg KCl haG 1 . Results: The results showed that the age treatment of coconut plants had a very significant effect on plant height, number of rows per cob, production per hectare and weight of 1000 seeds. Variety treatment significantly affected the weight of 1000 seeds. Conclusion: Cultivation of maize in dry land intercropping with coconuts over 15 years old shows the economic feasibility with an average R/C ratio of 1.75 and monoculture maize cultivation (without coconut) has the best level of economic feasibility with an average R/C ratio of 1.94.
