“…Dentre os aspectos que devem ser melhorados, na cultura do feijoeiro, está o manejo de adubação das plantas, uma vez que, com o fornecimento adequado e equilibrado de nutrientes, pelo uso de fertilizantes, pode-se obter aumentos significativos na produtividade de grãos (Miranda et al 2000, Andrade et al 2004, Arf et al 2011. Entretanto, para se auferir melhores resultados, é preciso adubar equilibradamente e posicionar o adubo corretamente, em relação às sementes e à superfície do solo (Meira et al 2005, Soratto et al 2005, Farinelli et al 2006ae 2006b, Kluthcouski et al 2006, Crusciol et al 2007, Valderrama et al 2009, Sant'ana et al 2010, Afonso et al 2011, Arf et al 2011, Barbosa et al 2011.…”

A cultura do feijão possui grande importância econômica e social, para a população brasileira. Entretanto, há aspectos que devem ser melhorados em seu cultivo, como o manejo de adubação das plantas. A subirrigação do feijoeiro, na entressafra do arroz, tem se mostrado alternativa viável para a produção de grãos, no ecossistema de várzea. Entretanto, poucos são os trabalhos realizados sobre adubação em condições de várzeas tropicais. Neste sentido, este estudo objetivou avaliar a produtividade de cultivares de feijoeiro comum, sob condições de várzeas tropicais e subirrigação, em Lagoa da Confusão (TO), na safra de inverno de 2008, submetidas a diferentes fontes, doses e parcelamentos de fertilizantes. Utilizou-se o delineamento experimental em blocos ao acaso, em esquema fatorial (cultivares x formas de adubação), com as cultivares separadas por grupos (preto, carioca e especial). A produtividade do feijoeiro foi maior com a antecipação da adubação nitrogenada, e ainda maior quando esta foi combinada com a suplementação de potássio em cobertura, sendo que Ouro Negro (grupo preto), Pitoco (grupo carioca) e Cranberry e BRS Embaixador (grupo especial) foram as cultivares mais produtivas. Com a utilização da adubação recomendada, Ouro Negro (grupo preto), Carioca (grupo carioca) e Jalo Precoce e BRS Embaixador (grupo especial) foram as mais produtivas, para cada grupo. As cultivares do grupo preto foram mais produtivas que as dos grupos carioca e especial.

“…The trait SP showed a somewhat stable response to the nitrogen treatment. Gomes Junior et al 2008did not find significant difference among nitrogen fertilization levels for SP, suggesting that this is a trait highly dependent on the genotype (Arf et al, 2011;Afonso et al, 2011) so its response to environmental changes are mild or non-existent (Souza, Andrade, Vieira, & Albuquerque, 2008). A similar response was observed for PW, which attained the greatest value at 50 kg N ha -1 for the IPR Tuiuiú cultivar.…”

“…On the other hand, for the IAC Milenio, the S trait showed greatest values at 100 kg N ha -1 (56 grains per plant) and was measured lower under 150 kg N ha -1 . This is due to the higher nitrogen availability at the early crop stages for the bean crop coming from the previous crop (ryegrass) residue (Afonso et al, 2011).…”

In order to identify the contribution of yield components to the final yield of dry beans, two widely adopted cultivars (IAC Milênio, and IPR Tuiuiú) were evaluated under nitrogen fertilization levels (0, 50, 100 and 150 kg N ha-1) in a crop-livestock system. Experiments were conducted under a randomized complete block with three replications design during two years (2016 and 2017) which were split in two cropping phases. A subplot factorial scheme of grazing heights by nitrogen fertilization (grains crops or pasture) was used. Dry beans crops were fertilized during the summer and yield components evaluated along with yield measurements. Descriptive and Pearson’s correlation coefficient analyses were performed and followed by path analysis to explain the interrelationship between yield components (explanatory traits) and yield (main trait). For IAC Milenio in 2016 cultivated as a second crop the main trait influencing yield the number of seeds per plant through direct and indirect effect of other traits, regardless of the topdressing nitrogen level applied. In 2017, a greater number of significant correlations was found for the IPR Tuiuiú cultivar. The number of pods per plant was the trait that affected yield most all nitrogen levels.

“…The common bean is a very important crop in Brazil because it is the main source of protein for poor people and has the advantage of being easily cultivated under different seasonal conditions. For these reasons, numerous studies have been conducted on various aspects of common bean cultivation, such as genetics [1], pathology [2] and plant nutrition [3].…”

The foliar application of micro-and macronutrients is often practiced by farmers to improve yield and seed physiological potential. For calcium and molybdenum, positive results have been observed, even in soils with high nutrient content. The purpose of this study was to assess the effects of foliar applications of calcium and molybdenum on yield and seed physiological potential in common bean plants. A randomized block design was implemented, with the treatments fixed in a factorial scheme: two molybdenum rates (with or without) and four calcium rates, with four replications. The calcium rates applied on the leaves were 0, 150, 300 and 600 g•ha −1 for the first year of the investigation (2005) and 0, 300, 600 and 900 g•ha −1 for the second year (2006). In both years, the molybdenum rates applied on the leaves were 0 g•ha −1 (without) and 75 g•ha −1 (with). The results showed that the foliar calcium application, with or without molybdenum, did not improve yield. Foliar application of calcium alone improved seed physiological potential in common bean plants when applied at the full bloom stage.
