MEDINA-CUELLAR, Sergio E. et al. Environmental influence on the productivity of the second honey harvest in Aguascalientes from 1998 to 2010. Rev. Chapingo ser. cienc. for. ambient [online]. 2014, vol.20, n.2, pp.159-165. ISSN 2007-4018.  https://doi.org/10.5154/r.rchscfa.2013.09.031.

We analyzed the effect of temperature, rainfall, rainfed harvested area and labor applied on honey production in the second honey harvest season (1998-2010), in Aguascalientes. This analysis was performed by modeling a Cobb-Douglas function by two-stage least squares. The criteria for variables selection was based on works concerning the phenology of bees, and the predominant source of nectar, as well as, the design of the production function. We obtained a model based on each apiary (78 apiaries) annual data, considering 4,901 beehives, with a R² in differences of 0.71. The honey per beehive production elasticity, in relation to rainfall, rainfed harvested area and labor were positive, and negative regarding last year honey production, and temperature. The weather and labor per beehive were the factors responsible for yield variability of honey per beehive.
