Profitability of using irrigation in forage cactus-sorghum intercropping for fa...
Silva,Thieres G. F. da; Jardim,Alexandre M. da R. F.; Diniz,Wellington J. da S.; Souza,Luciana S. B. de; Araújo Júnior,George do N.ABSTRACT Irrigation plays a fundamental role in advancing agricultural frontiers and increasing crop productivity, especially in semi-arid environments, because they exhibit high spatiotemporal rainfall variation. This practice is suggested even for adapted crops, such as forage cactus (Opuntia sp.), sorghum (Sorghum bicolor), and single or intercropping systems. In this study, aimed to evaluate the profitabili...

Lima,Lucivania R.; Silva,Thieres G. F. da; Jardim,Alexandre M. da R. F.; Souza,Carlos A. A. de; Queiroz,Maria G. de; Tabosa,José N.ABSTRACT The effects of the forage cactus sorghum configuration and different irrigation depths on the growth, water use and efficiency of the forage cactus production system were investigated in this study. The experiment was conducted in the municipality of Serra Talhada, Pernambuco State, Brazil, between the years 2012 and 2013. Forage cactus was distributed in randomized blocks with factorial scheme and fou...
