Description
Summary:The common bean has the capacity of nitrogen fixation in symbiosis with Rhizobium, but it is not enough to supply the necessities of the plant in relation to this nutrient. Molybdenum application aims to improve symbiosis in the Rhizobium-common bean plant, given its importance in the metabolism of this nutrient, thus being able to reduce the application of N fertilizer. Thus, the objective of the work was to evaluate the performance of irrigated winter beans, in a no-tillage system, with increasing levels of side dressing nitrogen application (zero, 30, 60, 90 and 120 kg ha-1) and its interaction with leaf application of Mo (zero and 80 g ha-1). The experimental design was randomized blocks in a 5 x 2 factorial scheme, with four repetitions. The research was carried out on soil previously cultivated with corn culture. The levels of nitrogen proved consistent regarding the effects on some production components, as well as on dry mass of plants, providing better development of irrigated beans cultivated under no-tillage. The application of molybdenum in leaves did not significantly influence the majority of evaluated parameters.
