Efeito do molibdênio na qualidade fisiológica de sementes de feijão

Abstract

The bean crop is of great importance for national agriculture, which is prominent in the population’s diet, and the country is one of the world’s largest producers and consumers of the crop. Given the above, the search for the quality of bean produc-tion gained prominence, prioritizing high productivity and nutritional composition. Molybdenum (Mo) is an essential micronutrient for common bean, this micronutrient has a fundamental action on the plant, since its function is related to nitrogen meta-bolism, having importance in biological nitrogen fixation. The objective of this work was to evaluate the effect of different sources of molybdenum applied to seeds. For this, the germination test, germination speed index and seedling dry matter mass of the cultivars IPR Sabiá and SCS204 Predileto were performed. To carry out the tests, two sources of Mo were used, 0.1416 of Teprosyn CoMo and 0.25 of YaraVita, both diluted in a volume of 20 mL 100 g-1 of seeds and control with distilled water where the seeds were submerged. for 15 minutes. The experiment was carried out in a bi-factorial scheme, with the levels of factor A, the cultivars IPR Sabiá and 204 Predile-to, and the levels of factor B, the four sources of molybdenum (treatments). If there was significance or interaction, the data were submitted to the Tukey Test at 5%. conclude that the interaction between the seed treatment with molybdenum in the IPR Sabiá and 204 Predileto cultivars was not significant. The application of Mo did not influence the variables G, MS and IVG.
