ARRIETA AGUILAR, Karen Fernanda et al. Analysis of temperature and precipitation in two avocado-growingareas of the state of Morelos: period 1956-2019. Rev. Mex. Cienc. Agríc [online]. 2023, vol.14, n.4, pp.543-554.  Epub Aug 04, 2023. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v14i4.3161.

Due to its edaphoclimatic conditions, the state of Morelos has a high potential for the development of the avocado industry, however, it faces the threat of the modification of the optimal temperature and precipitation conditions for the production of Persea americana Mill., cultivar Hass. The objective of this work was to identify the modifications in temperature and precipitation in three periods in two avocado-growing areas in Morelos in 2019. Two climatological stations were selected, one in Cuernavaca and another in Tetela del Volcán, for the temporal analysis three periods of five years each were established from the year 1956 with a difference of 30 years between periods. An analysis of variance was performed, Fisher’s LSD statistical test was used to find differences between the means of the parameter values (0.05). Significant differences were found in the maximum temperature for the municipality of Cuernavaca, as well as in the minimum temperature in Tetela del Volcán, both with a tendency to increase. Precipitation analysis showed a significant increase in the means by period in both localities. It is concluded that the results obtained point towards an increase in temperature in the study sites of importance in the production of avocado. Precipitation shows an increase in annual volume in current years; nonetheless, the main threat to the cultivation of this fruit is the lag of the season and the amount in which the rains occur.

Keywords : avocado; climatic conditions; production.
