SOLTERO-DIAZ, Leonardo; GARAY-LOPEZ, Carlos  y  RUIZ-CORRAL, José Ariel. Yield response of maize hybrids to different distances between furrows and density plants. Rev. Mex. Cienc. Agríc [online]. 2010, vol.1, n.2, pp. 149-158. ISSN 2007-0934.

Maize farming in narrow furrows is a new technique that is being evaluated in Mexico. This investigation was carried out during the 2007 spring-summer cycle, on maize farming in three locations in the area of Ciénega de Chapala, in the state of Jalisco. The aim of the experiment was to evaluate the distance between furrows (76 and 50 cm), three plant densities (75 000, 90 000 and 105 000 plants ha-1) and five hybrids, in order to know which treatment provides the highest yield. With the combination of all three studied factors, a complete factorial was obtained, with 30 treatments. The experimental layout was a randomized complete block design in a split-plot treatment arrangement with three replications and an arrangement in divided parcels, with the large parcel being the distance between furrows and as subplots, the hybrid factors and plant densities, respectively. A variance analysis was carried out as a whole, and an average analysis for the grain yield variable using the program SAS. Results indicate that the highest grain yield was obtained with the narrow furrow at 50 cm and a density of at least 90 000 plants ha-1; the grain yield increased 9.06% when reducing the distance between furrows from 76 to 50 cm, therefore it is suggested to use this recommendation to increase commercial production of maize in the area in question.
