“…Moura et al (2012) stated that bean yield is related to the population of plants because the spatial arrangement affects the efficiency of solar radiation absorption. Santos et al (2014b) found increased seed yield up to 15 plants m -1 , and reduced seed yield from that point on. In this work, however, seed yield was similar at different plant densities, thus evidencing crop compensatory growth in both seasons.…”

Brazil’s production of common bean is insufficient to supply the domestic market. Factors such as plant density, cultivar, growing season, and nutrient uptake affect bean yield, suggesting the need for more studies to optimize bean production. The objective of this work was to evaluate the effect of plant density on seed yield components and nutrient uptake of two common bean cultivars grown in two different seasons. Field experiments were carried out at the IAPAR experimental site in Santa Tereza do Oeste, Paraná, Brazil in the wet and dry season using five planting densities: 6, 8, 10, 12, and 14 plants m-1. The experimental design was randomized blocks with four replications and two bean cultivars of different growth types. The cultivars used were ‘IPR Curió’ (type I) and ‘IPR Tangará’ (type II), both have erect plant architecture and belong to the Carioca group. Obtained data underwent analysis of variance and regression. Macronutrient uptake was not affected by crop density probably due to nutrient availability and compensatory growth of the crop. High crop density per linear meter decreased the number of seeds and pods per plant but did not affect the first pod height or yield in both cultivars and seasons.

“…This reduction also increased grain yield (Shimada et al, 2000;Masa et al, 2017); however, the effect of increasing plant population on yield is variable: Shimada et al (2000) observed a decrease in yield, while Masa et al (2017) reported an increase for this variable. In turn, Silva et al (2012), Santos et al (2014), and Guimarães et al (2019) reported that plant population did not affect yield.…”

“…Several authors reported the effects of spatial arrangement on common bean yield and its components. Increasing the number of plants per row or decreasing the spacing between rows decreased the number of pods per plant (Shimada et al, 2000;Santos et al, 2014;Masa et al, 2017;Guimarães et al, 2019), the number of grains per plant (Shimada et al, 2000), and the number of grains per pod (Masa et al, 2017). Moreover, Masa et al (2017) observed that the increase in the number of plants per row increased leaf area index, plant height, and dry matter, and decreased leaf area and 100-grain weight.…”

“…Variation in the spatial arrangement of bean plants affects several yield components, especially the number of pods and grains per plant. The number of pods is the first formed yield component in the reproductive phase, being negatively affected by the increase in plant population due to the increase in intraspecific competition (Santos et al, 2014). This yield component depends on the number of plant nodes, either in the main branch or in lateral branches.…”

“…An increase in this variable can cause abortion of flowers and grains in the pods, decreasing seed production due to lower availability of photoassimilates in an environment with more competition for light. Hundred grain weight, on the other hand, is the yield component least influenced by plant population since it is a character of qualitative inheritance, little influenced by the environment and controlled by few genes (Santos et al, 2014).…”

Management of plant architecture, spacing and population on the yield of super early common bean

2020

For efficiency in the use of production factors and maximization of the yield of cultivars, it is essential to determine the most appropriate spatial arrangement for each cultivar and environment. This study identifies the effects of artificial adjustment of plant architecture, spacing between rows, and plant population on the yield of the super early common bean cultivar BRS FC104. We conducted the experiment in randomized blocks with subdivided plots and three replicates. In the plots, we assessed the spacing between rows (22.5, 45.0, and 67.5 cm). In the subplots, we considered the levels of artificial adjustment of plant architecture (maintenance of one or three lateral branches and control without architecture adjustment). In the subsubplots, we assessed populations of 6, 11, 16, and 21 plants per meter. The number of pods per plant increased with the increase in spacing between rows and with the reduction in plant population. Grain weight, in turn, increased with the reduction in spacing between rows and with the increase in plant population up to 14.7 plants per meter. Regarding grain yield and seed economy, the most suitable spatial arrangement for the super early cultivar consists of a 22.5 cm spacing between rows with about 12 plants per meter. The change in plant architecture, with the removal of lateral branches, is not effective to maximize yield.

Pod positioning and grain yield of common bean as affected by sowing density, nitrogen fertilization and fertilization depth

The positioning of pods in common bean directly affects grain losses in mechanized harvesting. However, only few studies have assessed facttors that can affect pods positioning. The objective of this work was to determine the effect of plant density, nitrogen fertilization, and fertilization depth on the distribution of pods of the common bean. The field experiments were carried out in two cropping seasons, 2017 and 2018, during the winter period in the Cerrado region. The experimental design was randomized blocks in a 4x2 factorial scheme, with four replications. The treatments consisted of the combination of four sowing densities (5, 10, 15, and 20 plants m-1) with two depths of fertilizer application (6 and 12 cm). The results allowed inferring that the depth of the fertilization does not affect the distribution of pods in the common bean. Plant density does not affect common bean grain yield. More than a quarter of the common bean pods of the BRS FC104 are positioned close to the ground, below 100 mm, in the area where harvester machines operate. Nitrogen fertilization and plant density affect the distribution of pods in common bean plants. At higher doses of N (90 kg ha-1), plant density should be increased. On the other hand, at lower doses (45 kg ha-1), plant density must be reduced. It is concluded that the sowing density can be an efficient strategy to provide the highest positioning of pods in the upper part of the common bean plants, reducing harvest loss.
