BAHENA-DELGADO, Gregorio et al. Water sustainability in creole corn production in Xalostoc, Morelos, México. agric. soc. desarro [online]. 2009, vol.6, n.2, pp.197-205. ISSN 1870-5472.

A research was carried out in the experimental field of the Universidad Autónoma del Estado de Morelos, East Campus, where the behavior of twenty four Creole corn genotypes and one witness variety, cultivated in a drip irrigation system with fertirrigation technique, was evaluated. The experimental design was random complete blocks with two replications. The plots were made up of two rows, 6 m long. The distance between rows was 1 m and 0.3 m between plants on the line. Ten cobs were harvested randomly when they had 14% humidity. Water applied in each watering was measured. The highest yields (p≤0.01) were found in Blanco Jonacatepec Morelos (BJM1) (3 405 kg ha^-1), Blanco Coacalco Puebla (BCP1) (3 116 kg ha^-1) and variety 537 (2 918 kg ha^-1). The amount of water used was 3 002 m³ ha^-1. Good efficiency was obtained in water productivity. Drip irrigation with fertirrigation improved productivity of Creole corns, water is saved, and its use efficiency increases.
