- Abstract
The objective of the present study was to identify the best sowing date for new experimental varieties of corn and also, to select the best corn genotypes. The work was carried out in the experimental field of the Instituto Tecnologico de Roque, Celaya, Gto., Mexico. The corn genetic material was provided by CIMMYT and evaluated for two sowing dates, June 25th (rainfed) and March 25th (irrigation) of 2016 and 2017, respectively. The following variables were measured: days at male and female flowering, plant height, cob height and yield. The study was conducted as a Latice experimental design with three replicates. Mean comparison was performed by Least Significant Difference (LSD). Statistically significant differences for treatments and sowing dates were detected. The best sowing date was March 27th, favoring a corn grain production of 12.4 t ha-1 (12%, moisture content basis), compared to the 11.1 t ha-1 yield for June 25th sowing date. In grain yield, the genotypes 9 (RS98TLW-5 B) and 6 (RS98TLW-2 B) were the best with recoveries of 13.0 and 14.0 t ha-1, respectively.
