| Abstract | Nitrogen fertilization besides stimulating the growth of plants is one of the techniques that can reduce the effect of salinity in the plants, whose tolerance can also vary between species and even between genotypes of the same species. The objective of this work was to evaluate the influence of different nitrogen rates on guava seedlings Paluma and Crioula irrigated with saline water. The experiment was carried out in a greenhouse of the CCTA UFCG with a randomized block design, in a 2 x 4 factorial scheme, corresponding to the cultivar of guava Paluma and genotype Crioula, fertilized with four doses of nitrogen (N): 70; 100; 130 and 160% recommended dose for guava seedlings, with four replicates, using two useful plants per experimental unit, irrigated with salt water of electrical conductivity (CEa) of 1.9 dS m. The 190 days after the emergency there was not significant interaction between the doses of nitrogen and the guava cv. Paluma and Creole genotype. The guava seedlings Crioula irrigated with saline water obtained higher phytomass in the root and Dickson quality index compared to the Paluma cultivar, which shows higher shoot growth. Nitrogen fertilization at the dose of 70% N (541,1 mg of N dm) promotes higher growth, phytomass accumulation and quality of the guava seedlings Paluma and Crioula. |
