“…Common bean studies have shown a linear decrease in pods per plant with increasing density [13]. In this study, the response of the cultivars to planting density in terms of pods per plant and hundred seed weight (HSW) varied between growing seasons according to cultivar and available soil moisture (Figure 3A,B).…”

“…Planting at high densities can be a strategy for obtaining optimum yield [9,10], although some studies have also shown its limiting effects on aspects of plant growth and development [11][12][13]. In this regard, it is essential to understand the effects of plant density on yield and its components by analyzing influencing factors and identifying major yield-density response curves [14].…”

To identify eco-efficient bean cultivars that can be planted at high densities for sustainable bean production under climate change, this study analyzed the performance of ten dry bean (Phaseolus vulgaris L.) cultivars grown at 90,000, 145,000 and 260,000 plants ha−1 under rainfed semi-arid conditions in Mexico. The study compared the yield and yield components (leaf area index (LAI), pods per plant, and hundred seed weight) of the cultivars. We also analyzed the dry matter distribution (DMD), growth rate (GR), radiation use efficiency (RUE), and harvest index (HI) of the best performing cultivars to determine how they respond to higher densities. The cultivars were established under similar planting and management conditions during two growing seasons. The precipitation for the first and second seasons were 175 and 492 mm, respectively, representing 57% and 160% of the mean precipitation in the area during the July–October growing period. Pinto Saltillo, a drought-tolerant indeterminate semi-prostrate cultivar, and Azufrado 2, a determinate shrub cultivar, performed best at high densities under low-precipitation conditions (175 mm). Both cultivars responded to the highest density (260,000 plants ha−1) with increases of 54% to 69% (0.7 to 1.1) in LAI and 21% to 86% (0.32–0.81 Mg ha−1) in yield. The two cultivars responded to increasing plant density with a modification in their fraction of DMD over plant parts and a change in their GR from 0.23–0.25 at low density to 0.96–1.74 gr m−2 day−1 at high density. The two cultivars had an RUE of 3.8 to 4.4 g MJ−1 and HI of 0.31 to 0.36 at high planting density. Farmers’ use of these commercially available cultivars proven to have high yields and the ability to respond favorably to high densities under rainfed conditions can be a viable short-term strategy to increase dry bean production for sustainable agriculture in semi-arid temperate regions.

There is evidence that the dry mass and nutrient accumulation rates of earlier (determinate) cultivars are faster than those of normal or late cycle (indeterminate). This study aimed to quantify the nutrient extraction and export and calculate the harvest index of determinate and indeterminate common bean cultivars. A randomized block design was used, with four replicates and eight cultivars (BRS FC104, TAA Gol, BRS Estilo, BRSMG Uai, IPR Tuiuiú, BRSMG Marte, Pérola and TAA Dama). The accumulation of dry matter and nutrients at the vegetative and reproductive stages, grain yield and grain nutrient export were determined. The early cultivars TAA Gol and BRS FC104 (Type I - determinate) accumulated more dry matter and nutrients during the vegetative stage than the indeterminate types II and III. However, from R7, no differences were observed among the cultivars for extractions or nutrient exports and harvest index. The cultivars exported 33, 11, 17, 2.3, 2.2 and 1.5 kg t-1 of grain for N, P2O5, K2O, S, Mg and Ca, respectively. Micronutrient exports were 14, 3.7, 70, 13 and 34 g Mg-1 of grain for B, Cu, Fe, Mn and Zn, respectively. The TAA Gol and BRS FC104 determinate cultivars reached the R9 stage at 77 days and the indeterminate cultivars at 85 (BRSMG Marte), 90 (IPR Tuiuiú and BRSMG Uai) and 93 days (TAA Dama and Pérola). BRS Estilo, BRS FC104 and TAA Gol had the lowest grain yield (< 2,200 kg ha-1) and TAA Dama the highest grain yield (3,275 kg ha-1).
