RESUMO:

The mung bean lines, selected by the breeding program of Embrapa Meio-Norte, are evaluated in the state of Mato Grosso during the off season to assess the adaptability and stability of production and other phenotypes of agronomic interest. In this work, the objective was to evaluate the response of lines to grain yield by applying fertilizers. The experiments were installed with and without application of fertilizer, with two tests per site, with the same lines, varying only the application of fertilizer, one without application (zero fertilizer) and the other with application of the formulated NPK 0-20- 20 in the sowing furrow and 45 kg / ha of nitrogen in cover, 25 to 30 days after emergence. The doses were defined considering the soil analysis at each location. The experiments were conducted in Sorriso-MT 2019, Sorriso-MT 2020, Sinop-MT 2019 and Sinop-MT 2020, totaling four trials without fertilizer and four with fertilization. Before sowing samples were collected composed of soil from the 0-0.20m layer, for physical, chemical characterization and interpretation of soil fertility. The tests consisted of eleven treatments, ten pre-commercial lines and one control. The experimental design was the DBC, with 3 replicates, plots of 2 lines of 4m in length and 0.50m spacing. The cultivation value, the length of the pod, number of grains per pod, the mass of 100 grains, grain yield and the grain index were evaluated. In general, a significant effect was observed between strains for all evaluated characteristics, indicating the presence of variation between them. The interaction between treatments and environments was not significant, indicating that there was no change in the classification of strains, regardless of whether the environment was fertilized or not. The strains that showed the best response to fertilization were BRA-000027 (MV4) and BG3 (MV10). The strain BRA-000027 was the one with the best general adaptability and also the best for unfavorable environments. The BG3 strain showed the best adaptability to favorable environments.
