“…The BRS Radiante yield, in turn, showed a negative correlation with solar radiation. Didonet (2010) found, for the Pérola, BRS Valente and Jalo Precoce cultivars, that the average global radiation incident from emergence to flower bud development showed no significant correlation with yield, but the radiation incident from emergence to the third trifoliolate leaf was negatively correlated with yield. The author states that the higher radiation probably favored a greater retention of pods than the ability of plants to sustain them, explaining the negative effect of solar radiation on common bean yield.…”

One of the great challenges in the use of irrigation, from an economic and environmental point of view, is to optimize the amount of water used in the production system. This study aimed at determining the viability of early sowing in the fall/winter harvest season, as well as its effects on the irrigation water use efficiency and yield of common bean. A crop model named CSM-CROPGRO-Dry bean, which simulates growth, development and yield of common bean as a function of environmental conditions, crop management and cultivar-specific parameters, was used to simulate the effects of 12 sowing dates on the irrigation water use efficiency and yield of the Pérola and BRS Radiante common bean cultivars. The simulated dates were as it follows: March 1st, 10 and 20 and April 1st, 10 and 20 (considered early); and May 1st, 10 and 20 and June 1st, 10 and 20 (considered traditional). The early sowing results in greater water economy than the traditional sowing season. Sowing in March provides a higher grain yield for the BRS Radiante cultivar and is similar to the traditional sowing of the Pérola cultivar. Concerning grain yield and irrigation water use efficiency, it is feasible to sow both cultivars in March.

“…Common bean is a crop with short cycle and, therefore, more sensitive to changes in climatic conditions (Hoffmann Júnior et al, 2007). In general, rainfall, air temperature and solar radiation are the climatic factors that influence its grain yield (Didonet & Silva, 2004;Didonet, 2010). Common bean presents low drought tolerance due to anatomical and physiological limitations as well as low resilience to water deficit conditions (Fancelli & Dourado Neto, 1991).…”

“…In general, the climatic factors that influence the grain yield of common bean are air temperature, solar radiation and rainfall (Didonet & Silva, 2004;Didonet, 2010). However, the climatic zoning published by several studies (Massignam et al, 1998b;Caramori et al, 2001;Maluf et al, 2001) and the Ministry of Agriculture, Livestock and Food Supply (Brasil, 2013a;Brasil, 2013b;Brasil, 2013c) for the south of Brazil states did not use solar radiation as a climatic variable to establish aptitude classes for climatic zoning.…”

The common bean (Phaseolus vulgaris L.) is a crop of high economic and social importance in Brazil. The objective of this study is to determine the impacts of climate change on climatic zoning, i.e., to define aptitude classes for cultivation and the periods recommended for the sowing times of the common bean in rainfed conditions for the period 2071 to 2100 in the states of Paraná, Santa Catarina and Rio Grande do Sul, in the south of Brazil. Three climate scenarios were used to evaluate the potential impact of climate change on climatic zoning of the common bean crop: current (baseline -1961-1990) and predicted future climatic conditions (2071-2100) (A2 and B2). The climatic zoning for the three scenarios (current, A2 and B2) were elaborated with the following aptitude classes: suitable and unsuitable for crop cultivation. Suitable for cultivation of common bean crop was considered when at least one 10 day period was indicated for sowing time. In the south of Brazil there is a spatial and temporal change of area suitable for cultivation and recommended sowing time by climatic zoning for the common bean crop in the future scenarios, both optimistic (B2) and pessimistic (A2).
