Abstract

The objective of this research is to study the relationships between absorbed photosynthetic active radiation (APAR) with the production of phytomass and yield of grains for the cultivation of wheat under different conditions of hydric stress. To this end, a field experiment will be set up, in which we will collect radiometric measurements, parameters relative to the soil, to the cultivation and meteorological parameters, during the entire cycle of the wheat cultivation. It is hoped, at the end, to find a correlation between phytomass and APAR, production of grains and APAR and the influence of hydric stress on APAR, phytomass and the production of grains. (AU)
