Gas exchange and growth of peanut crop subjected to saline and water stress

ABSTRACT Peanut crops are of great economic interest because their seeds used as an important source vegetable protein and edible oil. The objective this study was to evaluate the physiological indices growth peanut subjected saline water stress. experiment conducted in Auroras, Redenção, Ceará, Brazil using a completely randomized split plot statistical design. plots were composed irrigation treatments with varying levels electrical conductivity - ECw (1.0, 2.0, 3.0, 4.0 5.0 dS m-1), while subplots formed by regimes 50% 100% crop evapotranspiration. Plant height, leaf number, shoot dry matter, relative chlorophyll level, transpiration, temperature affected salt regime ETc provided better performance for variables stem diameter, mass peanuts.
