“…Comportamento diferente foi verificado por Jordan et al (2012a), em trabalho conduzido com a cultura do girassol em que o balanço de energia decresceu em função das lâminas de irrigação; ainda para a cultura da mamona, Jordan et al (2012b) verificaram que o balanço de energia não foi afetado pela irrigação.…”

RESUMOEste trabalho foi realizado com o objetivo de avaliar a viabilidade econômica e energética da cultura do feijoeiro comum de terceira safra com lâminas de irrigação na região Noroeste do Paraná. O experimento foi implantado com seis lâminas de irrigação e quatro repetições, em delineamento de blocos ao acaso. A cultura do feijoeiro não foi viável economicamente sem irrigação. Os lucros cresceram com o aumento das lâminas de irrigação atingindo um lucro operacional total de R$1.427,24 ha -1 na lâmina de 333 mm. O preço de equilíbrio sem irrigação foi de R$ 134,06 e R$ 152,65 a saca, em curto e longo prazos, respectivamente. A irrigação favoreceu o balanço energético (energia extraída/energia utilizada) de maneira linear atingindo 1,63 na aplicação da maior lâmina (333 mm).Palavras-chave: custo operacional de produção, manejo de irrigação, terceira safra, balanço de energia Economic analysis and energetic viability of the common bean crop under irrigation ABSTRACT This study was conducted to evaluate the economic and energetic viability of the third season of common bean under irrigation depths in the northwestern region of Parana. The experiment was established with six irrigation levels and four replications in a randomized block design. The bean crop was not economically viable without irrigation. Operating profit increased with increasing irrigation depths, reaching a total operating profit of R$ 1,427.24 ha -1 by 333 mm irrigation depth. The equilibrium price without irrigation was R$ 134.06 and R$ 152.65 bag -1 , short and long term, respectively. The irrigation favored the energy balance extracted (energy/used energy), reaching 1.63 in the application of greater depth (333 mm).

“…Irrigation is among the technologies that most contributes to the increase of productivity (Lira et al, 2015;Pereira et al, 2015); however, it also increases the input (consumption) of energy in the agricultural system. In this sense, some studies have been carried out over the last years aiming to analyze the energetic ratio of irrigated crops (Go mes et al, 2013, Jordan et al, 2012aJordan et al, 2012b).…”

This study was carried out with the objective of assessing grain yield, economic analysis and energy balance of three sunflower genotypes with and without irrigation. The experiment was installed in the Experimental Farm of the Faculty of Agrarian Sciences of the Federal University of Grande Dourados in the 2011/2012 and 2012/2013 harvests in Dourados-MS, Brazil. The experimental design used was a random complete block design with subdivisions, with and without irrigation (plots), with three genotypes (subplots) and four replications, constituting 24 plots. There were no differences in productivity among the genotypes. The irrigation increased the operational cost of the sunflower crop production, but it did not economically obstruct the activity, due to the increase of productivity of 74.5% and 30% in

ABSTRACT:The objective of this study was to evaluate the yield and energy balance of four sorghum genotypes in irrigated and rainfed crops. The experiment was conducted in an irrigation and drainage unit at the Federal University of Grande Dourados (UFGD), in Dourados, Mato Grosso do Sul state (Brazil). The experimental design was a randomized complete block design with split plots (with and without irrigation), testing four genotypes (BRS 506, CV 007, CV 147, and EJ 7281) with four replicates (32 plots). Irrigation provided yield increase in all four genotypes. The respective yield increases were 85.89%, 71.82%, 64.28%, and 63.36% for genotypes EJ 7281, BRS 506, CV 147, and CV 007. The energy efficiency (produced/ used ratio) was on average 3.5 under irrigation, and 2.8 for rainfed crops. These results indicate the lack of competition between sorghum and sugarcane, being the first an alternative for off-season. Irrigation increased productivity, leading to an increase in yield and, consequently, in the amount of extracted energy. Yield gains in response to irrigation were more pronounced for genotype EJ 7281. There was a positive impact of irrigation on the energy balance of the four genotypes, increasing energy efficiency.
