Bean cultivars production subjected to molybdenum foliar fertilization

Abstract

Research aimed at selection of bean cultivars and molybdenum leaf fertilization in Alagoas State is still scarce. In this experiment, we evaluated the performance of cultivars of common beans in the absence and presence of molybdenum folair fertilization of Alagoas State. The experiment was carried out between May and July 2016 on Arapiraca city - AL. The experimental design was a randomized block, with four replications, in an arrangement 5 x 2, concerning the five bean cultivars (BRS Amethyst BRS Comet BRS Style BRS Remarkable and BRS Pearl) and presence and absence of molybdenum leaf fertilization. The yield potential of cultivars and interference of molybdenum rich foliar fertilization was checked by statistical analysis of the variables productivity (kg ha-1), number of seeds per plant, number of pods, number of seeds per pod and seed weight per plant (g). The molybdenum foliar fertilization factor and interaction cultivar x molybdenum foliar fertilization showed no significance. The cultivate showed no significance for the variables number of seeds and pods per plant. However, there was significance for the other variables, the BRS Ametista showed the highest seed weight per plant (18.17 g), thus greater productivity (3,750 kg ha-1), followed by BRS Estilo (3,126 kg ha-1), both varieties showed itself as promising candidates under the worked soil and weather conditions. BRS Amethyst and Style cultivars are the most productive in the Alagoas Agreste. Leaf molybdenum at 35 and 45 days after sowing is not viable.
