Response of Maize (Zea mays L.) to Drought under Salinity and Boron Stress in the Atacama Desert.

ABSTRACT: The Lluta valley in northern Chile is a hyper-arid region with annual precipitation lower than 1.1 mm, and high levels of boron (B) from alluvial deposits are present together with other salts that originated from the Cretaceous. Under these abiotic conditions, the 'lluteño' maize (Zea mays L.) is of interest because it has adapted to the Lluta valley with high salinity levels and B excess in the soil and irrigation water. Water and salt stress coincide in heavily irrigated hyper-arid agricultural areas, yet they are usually studied in isolation. We investigated in field conditions the combined effects of drought (22 days with no irrigation) under salinity (ECe: 5.5 mS cm^-1; Na+: 17.8 meq L^-1) and B (21.1 meq L^-1) stress on physiology, growth, yield,
