Growth, water use and efficiency of forage cactus sorghum intercropping under different water depths AGRIAMBI
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 four replicates, in split plots (5 x 2), with five irrigation depths (0, 8.75, 17.5, 26.25 and 35% of the reference evapotranspiration, ET0) and two cropping systems (forage cactus monocropping and forage cactus sorghum intercropping). Crop evapotranspiration was calculated through soil water balance. The ratio between crop and reference...

Nitrogen doses and water balance components at phenological stages of corn Scientia Agricola
Silva,Monica Martins da; Libardi,Paulo Leonel; Fernandes,Flávia Carvalho Silva.
Determining the intensity of the water balance components in the control volume of a soil, and consequently defining the most likely periods of occurrence of a water deficit in a crop, is an exercise that requires knowledge about soil, climate and plant factors. This research aimed to evaluate soil water balance components at phenological stages of corn (Zea mays L.) under no-till system, when fertilized with 60, 120, and 180 kg ha-1 of nitrogen. The field experiment was carried out in Piracicaba, State of São Paulo, Brazil, on a Typic Hapludox. Evaluations were made in the 2004/2005 and 2005/2006 corn cropping seasons, divided over three stages according to the plant's phenology. Runoff was not taken into account. Measurements were made for precipitation...
