PAR RADIATION INTERCEPTATION IN IRRIGATED AÇAIZEIRO PLANTATION IN NORTHEASTERN PARAENSE
Micrometeorology, Productivity, Microsprinkling.
The açaí crop is not very demanding in terms of soil type, presenting excellent performance even in poor and acidic soils, but it shows significant productivity in places where the soil is classified as fertile. However, for a successful expansion to other areas, it is necessary to know how the culture behaves in different environmental conditions from those considered natural to the species, that is, flooded areas (várzea) of the Amazon. It is known that strategies to increase the production of both agricultural and livestock systems must be well designed since producing within the Amazon region requires increasing productivity without the need to deforest new areas in order to minimize the negative impacts of anthropic activities on the Brazilian Amazon. Understanding how photosynthetically active radiation (PAR) affects production systems is essential since this variable is part of the photosynthesis process. The influence of solar radiation interferes with their biological, physical and chemical behaviors, and its occurrence in, it determines the production of biomass, influences the dynamics and spatial distribution of the species in the environment in which it is inserted. Therefore, the objective of this work is to study the behavioral interaction between the productivity of the açaí palm and the RFA radiation.
