HERNANDEZ-TECOL, Karla et al. Grain production potential of soybean cultivation in the Puebla Valley. Rev. Mex. Cienc. Agríc [online]. 2022, vol.13, n.5, pp.853-862.  Epub 10-Out-2022. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v13i5.3229.

In Mexico, soybean production does not meet demand, so it is imported from other countries. This crop, produced mainly in the tropics, can be extended to the temperate zone to increase domestic production. Therefore, the present study evaluated the productive behavior of seven experimental selections and two commercial varieties of soybean in 2018, in three sites of the Puebla Valley with altitudes ranging from 2 190 to 2 240 m. The experimental design was in random blocks with four repetitions analyzed in a combined way. The experimental unit was four furrows five meters long and 70 cm wide. The variables evaluated were flowering, plant height, canopy width and grain production. The earliest varieties to flowering were ‘Hoja Seca Original’, ‘Hoja Seca Vainas Abundantes’ and ‘Varita’ with 81, 78 and 82 days, respectively, compared to the others that had 99 days on average. The locality where flowering occurred the fastest was Coronango (89 days). The varieties that differed the most in yield were Varita and Nainary, which on average had 3.42 and 2.02 t ha-1. The locality of La Ciénega had a higher yield (3.77 t ha-1) than the other two localities. In conclusion, the early varieties Varita, Hoja Seca Vainas Abundantes and Hoja Seca Original were the earliest and had the highest grain yield, therefore, they may be the most recommended for the area in question, which shows some potential.
