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.

SUMMARYThree cultivars of P. vulgaris, tested 39 and 69 days after planting, differed in the extent to which nitrogen (C2H2) fixation and nodule development were affected by plant density.At the 39-day harvest the climbing cultivar P590 declined in fixation from 15·1 μmol C2H4 produced/plant/h at 8·5 plants/m2, to only 4·2 μmol C2H4 produced/plant/h at 41·5 plants/m2; while the prostrate P498 showed consistently high fixation from 8·5 to 41·5 plants/m2. Variation in nitrogen fixation could be explained largely by change in nodule weight, though specific nodule activity (SNA) was affected, particularly in the cultivar P590. Since the percentage soluble carbohydrate in nodules of two varieties increased at certain planting densities while SNA decreased, some nodule dysfunction is possible.Density changes affected leaf, root and stem development in all cultivars, leaves on the lower nodes being most severely affected.At the 69-day harvest two varieties were advanced in filling the pods and showed poor nodulation and limited fixation, even at the widest plant spacings, while nodulation and nitrogen (C2H2) fixation in the third variety, which had just flowered, showed optima similar to the earlier harvest.

A caracterização de riscos climáticos para algumas culturas tem sido feita com modelos de simulação e para a cultura do feijoeiro (Phaseolus vulgaris L.) tem-se utilizado o CROPGRO-Dry Bean. Esse modelo calibrado e testado para a região de Santo Antônio de Goiás, GO, foi utilizado na análise de risco climático de quebra relativa de produtividade da cultura naquela região. Para as simulações utilizou-se a série de dados climatológicos (1978 a 1998), as características físicas, químicas e hídricas do solo local (Latossolo Vermelho perférrico), e o módulo "seasonal" do DSSAT 3.5. Foram feitas simulações para a região, a fim de se obter as produtividades potencial (Yp, sem restrição de água no solo) e real (Yr, com restrição dependente das chuvas) da cultivar Carioca. A quebra de rendimento, definida por Q(%) = [1 - (Yr/Yp)].100, foi calculada para cada uma das 36 épocas de semeadura simuladas ao longo do ano, nos 21 anos avaliados, sendo convertidas em freqüência relativa para análise dos resultados. Obteve-se Q > 50% na semeadura da "seca"; Q = 34%, em média, na semeadura das "águas"; e Q > 95%, na semeadura de "inverno". Esses resultados enfatizam a necessidade de irrigação suplementar nas semeaduras da "seca" e das "águas", e durante todo o ciclo, nas semeaduras de "inverno".

O experimento foi conduzido na Embrapa Arroz e Feijão, no município de Santo Antonio de Goiás, GO, num Latossolo Vermelho escuro argiloso. A irrigação foi realizada por microaspersão e o manejo através de tensiômetro e a curva característica de água no solo, irrigando toda vez que o potencial mínimo de água do solo atingia -30 kPa.  A análise dos resultados mostrou  diminuição do número de irrigações e aumento do turno de rega nos tratamentos onde a cobertura  atingiu mais de 50% da superfície do solo.  A cobertura do solo não influenciou na produção de grãos e seus componentes, com exceção do número de grãos por vagem e propiciou maior eficiência do uso da água. O tratamento com 100% de cobertura apresentou os maiores índices de área foliar e o acúmulo da matéria seca não sofreu influência da cobertura.  UNITERMOS:  Phaseolus vulgaris L., sistema de plantio direto, Braquiária  CHIEPPE JÚNIOR, J.B.; PEREIRA, A.L.; STONE, L.F..

Effects of DIFFERENT mulch levels on Growth and yield OF COMMON beans under no tillage system.  2 ABSTRACT The objective of this research was to study the effects of five different treatments of grass (Brachiaria decumbens) straw mulch on common beans (Phaseolus vulgaris L.): 0% (0 t.ha-1), 25% (2,25 t.ha-1), 50% (4,5 t.ha-1), 75% (6,75 t.ha-1) and 100% (9,0 t/ha) designed by randomized blocks and four replications. Irrigation was applied when minimum soil water potential was about – 30kPa. Water management was based on tensiometers and soil water characteristic curve. A microsprinkler irrigation system was used.  The experiment was set up at the Experimental Station of Embrapa Rice and Bean (Empresa Brasileira de Pesquisa Agropecuária Arroz e Feijão) in Santo Antonio de Goiás,Brazil, in a Dark – Red Latosol soil. Results showed that the bean yield and his components were not affected by treatments, except for grain number/pod. Mulching increased water use efficiency and, consequently, decreased the number of irrigations when mulching reached more than 50% straw mulch.  The treatment with 100% of mulching presented the largest leaf area index and dry matter accumulation was not affected  by mulching.KEYWORDS: Phaseolus vulgaris, no tillage system, Braquiária decumbens L
