The influence of irrigation on agricultural production systems is significant; 330 million hectares are irrigated in the world, representing 20% of the arable surface; In Ecuador the surface is 1,152.000 ha, equivalent to 30% of the potentially irrigable surface, which contributes to 70% of national agricultural production. Water consumption for irrigated agriculture in the world represents 70% and in Ecuador it represents 80% of the total water extracted. At the Experimental Station of the Technical University of Machala, Ecuador, the influence of furrow and drip irrigation on the cultivation of corn (Zea mays L.) was evaluated, in a randomized block design with three treatments and three replications: furrow irrigation, surface drip irrigation and subsurface drip irrigation at 20 cm depth. With the application of furrow irrigation, the plant height, the volume of water applied and the dry grain yield were 2.49 m, 3,484 m3.ha-1 and 9,175 kg.ha-1; for surface drip irrigation, 2.65 m, 1,452 m3.ha-1 and 10,200 kg.ha-1; for subsurface drip irrigation, 2.59 m, 1,237 m3.ha-1, and 10,181 kg.ha-1. The highest water productivity in corn cultivation was obtained with subsurface drip irrigation of 8,23 kg.m-3Metrics
