“…The available N even without N application (control) can be attributed to the soil organic matter found in the NT area where the experiment was performed, which was established more than ten years ago. Similar results have previously been reported (SOUZA; SORATTO; PAGANI, 2011;MAIA et al, 2012;PEREZ;FERNANDES, 2014).…”

“…These results suggest that common bean cultivated at low plant densities can accumulate more aboveground DM biomass and therefore take up more N. Previous studies have shown increased N concentrations in common bean leaves with increasing N fertilizer rates (CRUSCIOL et al, 2007;CARVALHO;ARF, 2006;SOUZA;PAGANI, 2011;PEREZ;FERNANDES, 2014). Despite the effect of the studied factors, leaf N concentrations in this study were within the range considered adequate for common bean crops (30-50 g kg ), according to the guidelines of Ambrosano et al (1997).…”

“…However, no interaction between plant density and N rate for number of pods per plants was found. Previous studies also reported an increase in number of pods per plant with increasing N rates up to 100 and 120 kg N ha -1 in the cultivar Pérola (CRUSCIOL et al, 2007;PEREZ;FERNANDES, 2014;MOREIRA et al, 2013). Nevertheless, the results of this work provide an evidence that depending on the growth condition, application of N rates up to 180 kg N ha -1 can increase the number of pods per plant.…”

“…However, Shimada, Arf and Sá (2000) did not report a plant density effect on number of grains per pod of common bean. Changes in this characteristic as a response to N application have not been frequently reported in previous studies (CRUSCIOL et al, 2007;MAIA et al, 2012;PEREZ;FERNANDES, 2014).…”

“…Alvarez et al (2005) reported an increase of irrigated common bean grain yield with N rates exceeding 100 kg N ha -1 . Also, Soratto, Carvalho, and Arf (2006), Soratto, Perez, and Fernandes (2014), and Moreira et al (2013) reported an increase in common bean grain yield with the addition of 120-140 kg N ha -1 and attributed this effect to the increase of pods per plant. These findings also support the hypothesis that higher plant-available N is needed when the plant population is reduced.…”

-The objective of this work was to evaluate the effect of plant densities and sidedressed nitrogen (N) rates on nutrition and productive performance of the common bean cultivars IPR 139 and Pérola. For each cultivar, a randomized complete block experimental design was used in a split-plot arrangement, with three replicates. Plots consisted of three plant densities (5, 7, and 9 plants ha -1 ) and subplots of five N rates (0, 30, 60, 120, and 180 kg ha -1 ). Aboveground dry matter, leaf macro-and micronutrient concentrations, yield components, grain yield, and protein concentration in grains were evaluated. Lower plant densities (5 and 7 plants m -1 ) increased aboveground dry matter production and the number of pods per plant and did not reduce grain yield. In the absence of N fertilization, reduction of plant density decreased N concentration in common bean leaves. Nitrogen fertilization linearly increased dry matter and leaf N concentration, mainly at lower plant densities. Regardless of plant density, the N supply linearly increased grain yield of cultivars IPR 139 and Pérola by 17.3 and 52.2%, respectively.Keywords: Phaseolus vulgaris. Nitrogen. Plant population.

DENSIDADE DE PLANTAS E ADUBAÇÃO NITROGENADA NA NUTRIÇÃO E PRODUTIVIDADE DE CULTIVARES DE FEIJÃORESUMO -O objetivo do trabalho foi avaliar o efeito da densidade de plantas na fileira e de doses de nitrogênio (N) em cobertura na nutrição e desempenho produtivo das cultivares de feijão comum IPR 139 e Pérola. Para cada cultivar, o delineamento experimental utilizado foi em blocos ao acaso, em parcelas subdivididas e três repetições. As parcelas consistiram de três densidades de plantas (5, 7 e 9 plantas m -1 de fileira) e as subparcelas de cinco doses de N (0, 30, 60, 120 e 180 kg ha -1 ). Foram avaliadas: matéria seca da parte aérea, teores de macro e micronutrientes na folha diagnose, componentes da produção, produtividade de grãos e teor de proteína nos grãos. Menores densidades de plantas (5 e 7 plantas m -1 ) proporcionaram maior produção de MS e número de vagens por planta e não reduziram a produtividade de grãos. Na ausência da adubação nitrogenada, a redução da densidade de plantas diminuiu o teor de N nas folhas do feijoeiro. A adubação nitrogenada aumentou linearmente a produção de matéria seca e o teor de N nas folhas do feijoeiro, principalmente sob as menores densidades de plantas. Independentemente da densidade de plantas, o fornecimento de N aumentou linearmente a produtividade de grãos das cultivares IPR 139 e Pérola em 17,3 e 52,2%, respectivamente.Palavras-chave: Phaseolus vulgaris.

Cover crop and early nitrogen management for common bean in a tropical no‐till system

et al. 2021

View full text Add to dashboard Cite

Common bean (Phaseolus vulgaris L.) has been grown under no‐till (NT), but nitrogen (N) management remains unclear when a previous cover crop is part of the farming system. In this study, we hypothesized that N applied to living cover crops, preceding the main grain crop of the rotation, can increase productivity and N‐use efficiency of the grain crop. Common bean was grown after palisade grass [Urochloa brizantha (Hochst. Ex A. Rich.) R.D. Webster] and ruzigrass [Urochloa ruziziensis (R. Germ. and C.M. Evrard) Crins] cover crops combined with N management [application to living cover crops 35 days before common bean seeding (DBS), 1 DBS, conventional, and control (zero‐N application)] in four experiment‐years. Dry matter (DM) and N content for palisade grass was consistently greater at termination relative to ruzigrass. Nitrogen application 35 DBS increased cover crop DM, N content, and the decomposition rate relative to the other N treatments. Greater common bean yield occurred following palisade grass than ruzigrass, and N application 35 DBS increased common bean yield compared to 1 DBS and conventional in one out of four experiment‐years. Only minor differences in the agronomic efficiency (AE) of applied N to cover crops were detected between 35 DBS and 1 DBS, and only for one experiment‐year, when palisade grass resulted in greater AE than ruzigrass. Applying N early to living crops such as palisade grass is an alternative N management strategy to the traditional approach for N fertilization in common bean.
