“…De qualquer forma, em diversos trabalhos, observa-se aumento de produtividade do feijoeiro com o fornecimento de molibdênio (Ferreira et al, 2003;Fernandes et al, 2005;Calonego et al, 2010;Rocha et al, 2011). As doses utilizadas têm variado em torno de 80 g ha -1 de Mo (Pessoa et al, 2000;Ferreira et al, 2003;Nascimento et al, 2009;Calonego et al, 2010) e a melhor época de aplicação situa-se em torno de 25 dias após emergência (DAE) (Pessoa et al, 2001;Ferreira et al, 2002;Calonego et al, 2010).…”

Foliar fertilization with nickel and molybdenum in common bean cv. 'Ouro Vermelho'The objective of this work was to assess the effect of foliar application with nickel (Ni) and molybdenum (Mo) on components of yield, growth and mineral composition of common bean cv. 'Ouro Vermelho'. The experiment was arranged in a randomized block design with four replications in a 5 x 2factorial scheme consisted of rates of Ni (0, 15, 30, ), and Mo (0 and 80 g ha -1) applied in the leaves 25 days after seeding. The elements were applied in the form of Ni chloride hexahydrate and ammonium molybdate. The foliar application of Ni did not change the foliar contents of N, P, K, Fe, Mo and Ni, but increased the content of N, Ni and the crude protein in the seed. The application of Mo decreased the foliar contents of P, Fe and Ni, but increased the foliar content of Mo and the content of N, Mo and crude protein in the seed. It was found that the foliar application of Ni and Mo did not affect the seed weight, the number of beans per pod, the number of pod per plant and the dry weight of the root system. The application of Mo increased in 21.62% the number of nodules.

“…Fernandes et al (2005) evaluated the application of foliar Mo and N, in-furrow or sidedress, to no-tillage bean on corn stover and also found no difference for PNP. However, reports of increased PNP in response to Mo application are common in the literature (Pessoa et al, 2001;Silva et al, 2003a;Nascimento et al, 2009). For the year effect, the average PNP was higher in 2010 (Table 3).…”

“…Although there is no response pattern to Mo, the increase in yield of the bean crop with supply of Mo has been reported in a number of studies in field conditions (Araújo et al, 2009;Nascimento et al, 2009;Biscaro et al, 2011;Rocha et al, 2011). Studies prove the feasibility of fertilizer foliar application on V4 stage bean, mainly of micronutrients tank-mixed with herbicides and pesticides to reduce costs and optimize equipment usage (Araújo et al, 2008;Silva et al, 2003b).…”

RESUMOMolibdênio aplicado com glifosato e isolado por via foliar em feijoeiro cultivado sobre palhada de milho no sistema de plantio direto O objetivo deste trabalho foi estudar o efeito da aplicação do molibdênio (Mo), em mistura com dessecante, em feijoeiro cultivado sobre palhada de milho (Zea mays), no sistema de plantio direto. Utilizou-se o delineamento em blocos casualizados, com quatro repetições, no esquema de parcelas subdivididas. Nas parcelas, foram aplicadas doses de Mo (0, 100, 200, Molybdenum mixed with glyphosate and alone via foliar spray in no-tillage common bean grown on corn stover

“…Overall, the mean was 26.02 g, which is nearly equal to the average indicated to the BRS style, which is 26 g (CARGNIM; ALBRECHT, 2010), demonstrating that decrease of M100-induced by lack of N did not happen in any of the treatments. Nascimento et al (2009) found no relationship between nitrogen fertilization and M100, a result that can be explained by the work done by Salgado et al (2012), who studied the effect of nitrogen levels in 12 cultivars and found different responses to N doses, although only three responded to nitrogen fertilization. Fernandes et al (2005), while evaluating fertilization in the planting furrow (0 and 20 kg ha -1 ) and on coverage (0 and 70 kg ha -1 ), showed a negative effect of nitrogen fertilization on the weight of 100 grains.…”

This study aimed to evaluate the effect of subdividing nitrogen fertilization on irrigated beans into two moments. The study was developed in Vera, MT, Brazil, from August to November 2012, under central pivot in direct sowing system. The experimental design consisted in randomized blocks with 10 treatments and four replications. Treatments consisted in dividing nitrogen application in two moments (sowing and coverage) with the final dose of 120 kg ha -1 except for the control treatment which received only 30 kg ha -1 at sowing. The following characteristics were evaluated: plant dry weight at flowering and at harvest, plant height and insertion of the first pod, nitrogen content in leaf and in grain, chlorophyll analysis (nitrogen sufficiency index and SPAD), nitrogen export, number of grains per pod and pods per plant, weight of one hundred grains and productivity. Pearson correlation was carried out for all factors. There was a significant difference between treatments only for productivity and nitrogen export, and the best results were observed in treatments that received fertilization equally divided between sowing and coverage. Production components that correlated with productivity were weight of one hundred grains and number of pods per plant.Keywords: Phaseolus vulgaris, winter cultivation, direct sowing system.Parcelamento da adubação nitrogenada na cultura do feijoeiro irrigado no Médio Norte do Mato Grosso RESUMO: O presente estudo objetivou avaliar a influência do parcelamento da adubação nitrogenada em duas épocas no feijoeiro irrigado. O estudo foi desenvolvido em Vera, MT, Brasil, no período de agosto a novembro de 2012, sob pivô central em sistema de semeadura direta. O delineamento experimental utilizado foi o de blocos ao acaso, com 10 tratamentos e quatro repetições. Os tratamentos consistiram na divisão da aplicação de nitrogênio em duas épocas (semeadura e cobertura) sendo a dose final de 120 kg ha -1 exceto em um tratamento controle que recebeu apenas 30 kg ha -1 na semeadura. Foram avaliadas as seguintes características: massa seca de plantas no florescimento e na colheita, altura de plantas e inserção da primeira vagem, teor de nitrogênio na folha e no grão, análise de clorofila (índice de suficiência de nitrogênio e SPAD), exportação de nitrogênio, números de grãos por vagem e vagens por planta, massa de cem grãos e produtividade, realizando-se correlação de Pearson para todos os fatores. Em relação aos tratamentos houve diferença significativa, apenas para a produtividade e exportação de Nitrogênio, sendo observado os melhores resultados nos tratamentos que receberam adubação dividida de forma igual na semeadura e em cobertura. Os componentes de produção que apresentaram correlação com a produtividade foram a massa de cem grãos e o número de vagens por planta. Palavras-chave:Phaseolus vulgaris, cultivo de inverno, sistema de semeadura direta.Recebido em fevereiro/2016; Aceito em julho/2016.
