Title : Effects of climate change on the development of beans (Phaseolus vulgaris L.) in the Lagunera region.

Abstract:

Climate change has in some way affected the temperature of the environment, so that the increase in heat, the decrease in the rainy seasons, as well as the presence of early frosts and / or the anticipation of late frosts are considered among other factors. that can affect the development of the bean crop (Phaseolus vulgaris L.)

Method: The research was carried out in an experimental field of the Antonio Narro Autonomous Agrarian University in the city of Torreón Coahuila Mexico located in the San Antonio de los Bravos ejido, three different varieties of beans were used: Pinto Centauro, Pinto Saltillo and Pinto Bravo through a randomized block design with three replications each, where three sowing dates were made with an interval of 7 days. The first sowing date was May 22, 2020, the second sowing date was May 29, 2020 and the third sowing date was June 5 to generate an approximate projection of 170,000 plants per hectare.

Result: The ANOVA method for a single factor was used to compare seed germination, vegetative development of plants and bean production. It was validated with the Tukey test with a reliability of 95 percent. Obtaining that there is a significant difference in the production of beans and in the vegetative development of the plant, showing no significant difference in the germination of seeds, thus rejecting the null hypothesis for bean production and for vegetative development of the plant and the null hypothesis is accepted for germination.

Conclusion: By using three different sowing dates, it was observed how the phenomena caused by climate change can affect the development of the crop, during the research atypical rains occurred during the flowering season, causing the flower to fall, affecting bean production. In addition, in the presence of excessive humidity, the presence of the fungus Sclertotium rolfsii.Sac developed. fungus that produces the drying of the plant causing in some lots a prevalence of 60% up to 70% of the population of the lot, mainly in the first two sowing dates. In this sense, the significant difference produced by the rejection of the null hypothesis is interpreted, both in vegetative development and in bean production, with respect to germination the null hypothesis is accepted because at the time of this process there were no Atypical meteorological phenomena, so it is recommended to continue with the research work modifying sowing dates until the optimal production date is found.
