Resumo
The washing of nutrients from plant leaves by rainwater is a recognized fact in the agronomic environment. With the advent of the practice of irrigating large areas, in different cultures, the phenomenon has not yet received the necessary attention. The objective of the study was to determine the leaf content of calcium and boron in the leaf blade of the common bean, due to the time of wetting of the plant, caused by the time of operation of the central pivot, in four different points of location in the field, along the equipment radius. The study was conducted in the municipality of Cristalina - GO, in a common bean field, privately owned, irrigated by the central pivot irrigation system. The cultivar used was BRS FC402. At the beginning of the flowering of the culture, samples of plant leaves were collected for leaf analysis. Until that moment of sample collection, the culture had received 150 mm of irrigation water. The samples were collected at four equidistant points along the central pivot radius, with four replications. The calcium and boron contents in the leaf blade were analyzed. The contents of these nutrients were greater the shorter the leaf wetting times by irrigation water.
