Enhanced-efficiency fertilizers, which provide a reduction in nitrogen (N) losses, can be a viable alternative for the anticipation of topdressing for the moment of sowing, besides reducing operations for the rural producer. This study aimed to determine the effect of the period of application of enhanced-efficiency nitrogen fertilizers on the grain yield of corn and common bean in the Cerrado region in the direct seeding system. The experiment was carried out during two crop seasons (2019/2020 and 2020/2021), under field conditions. The completely randomized blocks experimental design was used, being arranged in a 2x4+1 factorial, with four replicates. Treatments consisted of the combination of the following two periods of nitrogen application: at sowing and recommended (four open leaves of corn and third trefoil in beans); and of the four following types of nitrogen fertilizers: 1. urea + NBPT + Zeolite; 2. urea + B + Cu + Zeolite; 3. Super N; and 4. Urea. Additionally, a control treatment (without N) was included. Nitrogen values for application in the treatments were adjusted so that 150 kg ha-1 N was applied to the corn, cultivated in summer, and 90 kg ha-1 N was applied to the common bean, cultivated in winter. It was concluded that nitrogen sources and period of nitrogen application did not affect corn grain yield, yield components, and common bean grain yield. The application of nitrogen in corn or common bean provided significant increases in crop grain yield. |

ABSTRACT - The objective of this work was to evaluate the experimental precision of ten statistics in the evaluation of characters related to the technological quality of common bean (Phaseolus vulgaris) lines. Seventeen experiments were carried out between 2010 and 2019, with 116 common bean genotypes of different types of grain. Technological quality was determined for the following characters: mass of 100 grains, grain lightness value (L*), absorption, and cooking time. A significant genotype effect was obtained in 100% of the experiments for L* value and mass of 100 grains, in 76.92% for absorption, and in 94.12% for cooking time. The L* value and mass of 100 grains were determined with a high experimental precision by all statistics. Absorption and cooking time showed a high experimental precision, when analyzed by the following statistics: F-test value for genotype (Fc), genetic variation coefficient (GVC), relative variation coefficient (RVC), heritability (h2), and selective accuracy (SA). The statistics Fc, GVC, RVC, h2, and SA provided a high experimental precision in the evaluation of the characters related to technological quality in common bean lines. Selective accuracy is the most appropriate statistics to select superior common bean lines for grain and cooking quality in breeding programs. RESUMO - O objetivo deste trabalho foi avaliar a precisão experimental de dez estatísticas, na avaliação de caracteres relacionados à qualidade tecnológica, em linhagens de feijão-comum (Phaseolus vulgaris). Dezessete experimentos foram realizados, entre 2010 e 2019, com 116 genótipos de feijão de diferentes tipos de grãos. A qualidade tecnológica foi quantificada para os seguintes caracteres: massa de 100 grãos, valor de luminosidade do grão (L*), absorção e tempo de cozimento. Obteve-se um efeito de genótipo significativo em 100% dos experimentos quanto ao valor de L* e à massa de 100 grãos, em 76,92% quanto à absorção e em 94,12% quanto ao cozimento. O valor de L* e a massa de 100 grãos foram determinados com alta precisão experimental por todas as estatísticas. A absorção e o tempo de cozimento mostraram alta precisão experimental, quando analisados pelas seguintes estatísticas: valor do teste F para genótipo (Fc), coeficiente de variação genética (CVG), coeficiente de variação relativa (CVR), herdabilidade (h2) e acurácia seletiva (AS). As estatísticas Fc, CVG, CVR, h2 e AS propiciaram alta precisão experimental na avaliação de caracteres da qualidade tecnológica em linhagens de feijão. A acurácia seletiva é a estatística mais apropriada, para selecionar linhagens de feijão superiores quanto à qualidade de grãos e de cozimento em programas de melhoramento.
