“…Regarding the number of trifoliate leaves and shoot dry mass, no differences were found among the factors studied (Table 3). The results for shoot dry mass and trifoliate leaves were lower than those obtained by Sabundjian et al (2013) and Mingotte et al (2014), respectively. This difference might have occurred due to cultivar differences, since those authors used the 'IPR 139' and 'Pérola' cultivars, which have an indeterminate growth habit, unlikely 'IAC Imperador'.…”

“…A major production was achieved when beans were grown on single brachiaria straw, if compared to the others (Table 5). It is worth highlighting that the splitting of 30 + 60 + 00 reached values above 13 pods per plant, differing from those found by Sabundjian et al (2013). Notably, it should be said that the number of pods per plant is the most contributing productive attribute for grain yield in common bean (Barili et al 2011).…”

However, the nitrogen (N) dynamics in the soil can be altered by increased immobilization rates, with a direct influence on the use of this nutrient by crops.…”

The no-tillage system can change the nitrogen dynamics in the soil, being necessary to adjust the nitrogen fertilization in order to provide this nutrient during critical phases of the common bean growth. This study aimed at evaluating the agronomic and qualitative traits of common bean grown under different straw types, as a function of the topdressing nitrogen fertilization splitting. A randomized block experimental design, in a split-plot arrangement, with four replications, was used. The plots consisted of three straw types (maize, maize intercropped with brachiaria and brachiaria), while the subplots comprised the combination of these straw materials with 8 topdressing nitrogen fertilization splitting arrangements. The common bean on brachiaria straw shows higher grain yields and crude protein contents. The nitrogen fertilization splitting, as topdressing, interacts with the straw types, increasing the number of pods per plant. The common bean plants growing on plots with single-maize straw had a shorter time for maximum hydration. The topdressing nitrogen fertilization splitting has no effect on the common bean qualitative traits.

“…Resultados semelhantes foram encontrados por Sabundjian et al (2013), que verificaram maior produtividade do feijoeiro sobre palha de U. ruziziensis. A maior produtividade observada nesse sistemas de cultivo, deve-se, entre outros fatores, aos efeitos positivos dessa forrageira sobre as características físico-químicas do solo e também à sua reduzida relação C:N. Silveira et al (2011) verificaram produtividade de grãos de 2.310 kg ha -1 , no feijoeiro cultivado em sucessão a U. ruziziensis; essa produtividade foi associada ao aumento dos agregados do solo na camada de 0,0-0,20 m, explicado pela alta densidade de raízes e o alto teor de lignina da matéria vegetal, que favorecem a estruturação e a estabilidade dos agregados do solo.…”

Resumo -O objetivo deste trabalho foi avaliar a influência de doses de nitrogênio em cobertura e das palhadas de milho, de milho consorciado com braquiária e de braquiária sobre a produtividade e a qualidade de grãos do feijoeiro. O experimento foi realizado em área irrigada, no cultivo de inverno, após cinco anos da implantação do sistema plantio direto, em Latossolo Vermelho eutroférrico de textura argilosa. Utilizou-se o delineamento de blocos ao acaso com parcelas subdivididas e três repetições. As parcelas foram constituídas por palha de milho, palha de milho consorciado com braquiária e palha de braquiária; enquanto as subparcelas, pelas doses de N em cobertura correspondentes a 0, 40, 80, 120 e 160 kg ha -1. Todos os tratamentos receberam 17 kg ha 1 de N na semeadura. O feijoeiro cultivado sobre palha de braquiária atinge maior produtividade de grãos e maior eficiência agronômica. Os atributos qualitativos dos grãos não são alterados pelas diferentes palhadas avaliadas. A aplicação do N em cobertura aumentou o teor de proteína bruta e o tempo de cozimento dos grãos de feijão, além da produtividade de grãos do feijoeiro até a dose de 136 kg ha -1 de N.Termos para indexação: Phaseolus vulgaris, Urochloa ruziziensis, Zea mays, cultivos de cobertura, eficiência agronômica, feijoeiro irrigado, tempo de cozimento. Yield and quality of common bean cultivated on grass straws and fertilized with nitrogen under no-tillageAbstract -The objective of this work was to evaluate the effect of top-dressed nitrogen fertilization and of the straws of corn crop, of corn intercropped with Brachiaria, and of Brachiaria on grain yield and quality of common bean. The experiment was carried out under irrigation, in winter cropping, after five years from the implementation of a no-tillage system, in a clayey Oxisol. A randomized block design with split plots and three replicates was used. The plots consisted of the straws of corn, of corn intercropped with Brachiaria, and of Brachiaria; while the split plots consisted of top-dressed N at levels corresponding to 0, 40, 80, 120, and 160 kg ha -1. All the treatments received 17 kg ha -1 N at sowing. Common bean cropped over Brachiaria straw reaches higher grain yield and has increased agronomic efficiency. The evaluated straws did not affect the qualitative attributes of common beans. The application of top-dressed N increased protein contents and cooking time of the beans, besides grain yield up to the level of 136 kg ha -1 N.

“…Under these conditions, for the efficient implementation and management of NTS, crop rotation using species with high potential for straw production and high C/N ratio is essential to ensure soil coverage for a longer period. Corn (Zea mays) and the brachiarias Urochloa brizantha and Urochloa ruziziensis, especially the latter, stand out for the easy drying and less tiller cluster formation, which promote a more uniform soil coverage and facilitate the next crop sowing (Fiorentin et al, 2011;Costa et al, 2012b;Rodrigues et al, 2012;Sabundjian et al, 2013).…”

Agronomic performance of common bean in straw mulch systems and topdressing nitrogen rates in no-tillage

et al. 2015

View full text Add to dashboard Cite

In no-tillage systems, straw coverage on soil surface is the key to success, and the choice of crops for rotation is crucial to achieve the sustainability and quality that conservation agriculture requires. The objective of this study was to evaluate the agronomic performance of the common bean cultivar IAC Formoso sown in succession to three straw mulch systems (corn alone, corn/Urochloa ruziziensisintercrop and U. ruziziensisalone) and topdress nitrogen rates (0; 40; 80; 120 and 160 kg ha-1N), at the four-leaf stage, three years after the implementation of no-tillage. The experiment was arranged in a randomized block split plot design, with three replications. Common bean highest yields were achieved in succession to U. ruziziensisalone and intercropped with corn. The corn/U. ruziziensisintercrop provided both straw and seed production, allowing for quality no-tillage. Topdressed nitrogen influenced the common bean yield when in succession to corn alone, U. ruziziensisalone and corn/U. ruziziensisintercrop in no-tillage.
