Growth and photosynthetic pigments of passion fruit (Passiflora edulis) seedlings under foliar fertilization with nitrogen and irrigated with saline water

In the semiarid region of Brazil, salts found in water used irrigation. The objective was to analyze influence foliar fertilization with nitrogen as a mitigation salt stress passion fruit seedlings. design randomized blocks, treatments generated from Box’s Central Composite matrix, five electrical conductivities irrigation (ECw) (0.50; 0.98; 2.15; 3.32; 3.80 dS m-1) and doses (0.0; 0.30; 1.15; 1.97; 2.30 g L-1), four replicates. growth photosynthetic pigments were evaluated Application attenuated effect salinity on morphophysiological aspects increase caused negative effects characteristics
