A randomized complete block design in a 4x3 factorial consisted of four levels of irrigation water salinity ECw (0.3, 1.5, 2.5 and 3.5 dS m-1) and three different substrates [S = soil; EO = Soil + sheep manure (2:1); and SC = soil + commercial substrate (2:1)], with a total of 12 treatments with three replications and three useful plants per replication were used. The increase in salinity of irrigation water reduced the emergence, growth and dry matter accumulation of passion fruit seedlings, being the total dry matter the variable that was most affected by salinity. The substrate containing soil + sheep manure in the ratio of 2:1 promoted the highest initial growth and dry matter accumulation of yellow passion fruit seedlings, using a maximun level of 1.5 dS m-1 of saline irrigation were used.</p>}, number={4}, journal={Comunicata Scientiae}, author={Oliveira, Fernanda Andrade de and Lopes, Maria Ângela Casimiro and Sá, Francisco Vanies da Silva and Nobre, Reginaldo Gomes and Moreira, Romulo Carantino Lucena and Silva, Luderlândio de Andrade and Paiva, Emanoela Pereira de}, year={2015}, month={Dec.}, pages={471–478} }
