DIONICIO BELISARIO, Luis Olivas et al. Agronomic performance of corn hybrids at two locations of the central coast, Peru. Scientia Agropecuaria [online]. 2018, vol.9, n.3, pp.343-347. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2018.03.05.

An alternative to increase the productivity of corn grains is the correct choice of hybrid. The aim of the study was to evaluate the productive performance of three corn hybrids (Zea mays L.) at two locations on the central coast of Peru. The experiment was developed in Quilmaná and Herbay Alto, department of Lima. At each location, was adopted a randomized block design with three treatments and four replications. The treatments were represented by ATL 310 (triple hybrid), DK 7088 (single hybrid) and XB 8010 (double hybrid) hybrids. Evaluated the plant characteristics, spike and productivity. With data from both experiments combined analysis was carried out, preliminary evaluation of homogeneity of variance, and the means were compared using Scott-Knott test at 5% probability. According to the results, DK 7088 obtained higher rows of grains and grains per spike in Herbay Alto; while the largest spike mass and grain mass per spike were obtained by the three hybrids in Quilmaná. Among locations, the highest grain yield was obtained in Quilmaná; and among hybrids, was obtained by DK 7088. We conclude that the best location was Quilmaná; and the best hybrid, DK 7088.
