“…2021 Cavalcante, Dias, Nascimento and Freire (2011) observed a reduction in the photosynthetic efficiency of passion fruit plants subjected to irrigation with saline water at an electrical conductivity above 2.5 dS m -1 , at 448 days after transplanting. Wanderley et al (2018) also observed similar effects on sour passion fruit seedlings when subjected to increasing levels of electrical conductivity in irrigation water, from 0.3 to 3.1 dS m -1 .…”

The objective of this study was to evaluate the growth, photosynthetic pigments, and photochemical efficiency of sour passion fruit cv. BRS Rubi do Cerrado irrigated with waters of different cationic natures. The experiment was carried out from March 2019 to January 2020 in a protected environment belonging to the Academic Unit of Agricultural Engineering of the Federal University of Campina Grande (UFCG), Campina Grande, PB, Brazil. The treatments consisted of eight combinations of irrigation water with different cationic natures: S1 - Control; S2 - Na+; S3 - Ca2+; S4 - Mg2+; S5 - Na+ + Ca2+; S6 - Na+ + Mg2+; S7 - Ca2+ + Mg2+, and S8 - Na+ + Ca2+ + Mg2+. Plants in the control treatment (S1) were irrigated using water with an electrical conductivity (ECw) of 0.4 dS m-1, while the other treatments (S2; S3; S4; S5; S6; S7; and S8) were subjected to an ECw of 3.5 dS m-1. Sour passion fruit growth was affected by variations in the level of electrical conductivity, regardless of the cationic nature of irrigation water. The use of salinized water with sodium favored the synthesis of chlorophyll a, chlorophyll b, and carotenoids of passion fruit plants at 180 days after transplanting. The distinct cationic natures of irrigation water did not influence the fluorescence variables of sour passion fruit.

“…Resultados semelhantes foram relatados por Wanderley et al (2018) em mudas de maracujazeiro, no qual a salinidade da água de irrigação reduziu a altura em cerca de 12,2 cm por unidade com o aumento da salinidade, que resultaram em declínio de 34,18 cm (25,18%), e também do diâmetro do caule em 0,196 mm por unidade em incrementos na CEa.…”

O maracujá é uma das principais frutíferas produzidas e consumidas no Brasil, sendo que a região Nordeste é considerada a de maior produção. No entanto, o excesso de sais no solo e nas águas utilizadas na irrigação da região é prejudicial ao desenvolvimento das plantas. Nesse sentido, a adubação com nitrogênio (N) e potássio (K) se torna uma estratégia para minimizar os danos promovidos pelo estresse salino. Objetivou-se avaliar o crescimento e a eficiência fotoquímica de mudas de maracujazeiro submetidas ao estresse salino e adubação foliar com nitrogênio e potássio. O experimento foi realizado no Centro de Ciências Agrárias, Universidade Federal da Paraíba, Areia-PB. O delineamento experimental utilizado foi o de blocos casualizados, em esquema fatorial incompleto, com cinco níveis de condutividade elétrica da água de irrigação (CEa = 0,50; 0,98; 2,15; 3,32 e 3,80 dS m-1) e cinco doses de N e K (0,0; 29,08; 100; 170,92 e 200%), totalizando nove combinações, geradas através da matriz Composto Central de Box, com quatro repetições e duas plantas por parcela. Foram avaliados a altura de plantas, o diâmetro caulinar, a área foliar, a razão de área foliar, a fluorescência inicial, a máxima e variável, a razão Fv/F0 e o rendimento quântico do fotossistema II. A salinidade promove redução no crescimento e nos índices de fluorescência da clorofila a das mudas de maracujazeiro. A adubação foliar com N e K ocasiona maior crescimento e incrementos nos índices de fluorescência da clorofila a. Palavras-chave: Passiflora edulis f. favicarpa. Estresse Salino. Fluorescência da Clorofila. Abstract Passion fruit is one of the main fruit produced and consumed in Brazil, and the Northeast region is considered the one with the highest production. However, the excess of salts in the soil and water used for irrigation in the region is detrimental to the plants development. In this sense, fertilization with nitrogen (N) and potassium (K) becomes a strategy to minimize the damage caused by salt stress. The objective was to evaluate the growth and photochemical efficiency of passion fruit seedlings submitted to saline stress and foliar fertilization with nitrogen and potassium. The experiment was carried out at Center for Agricultural Sciences, Federal University of Paraíba, Areia-PB. The experimental design used was randomized blocks, in an incomplete factorial scheme, with five levels of electrical conductivity of irrigation water (CEa = 0.50; 0.98; 2.15; 3.32 and 3.80 dS m- 1) and five doses of N and K (0.0; 29.08; 100; 170.92 and 200%), totaling nine combinations, generated through the Central Box Compound matrix, with four replicates and two plants per plot. Plant height, stem diameter, leaf area, leaf area ratio, initial, maximum and variable fluorescence, Fv / F0 ratio and quantum yield of photosystem II were evaluated. Salinity promotes a reduction in chlorophyll a growth and fluorescence rates of passion fruit seedlings. Foliar fertilization with N and K causes greater growth and increases in chlorophyll a fluorescence indices. Keywords: Passiflora edulis f. favicarpa. Saline Stress. Chlorophyll Fluorescence.

Several researches have been evaluating the use of nitrogen fertilization as a way to attenuate the effects of salinity in different cultures. However, plant responses to nitrogen fertilization under saline stress conditions are quite complex and many divergent results are still found in the literature. In some studies, the application of nitrogen attenuates the effects of salinity only under low salinity conditions, in others no significant interaction between salinity and nitrogen is observed and in some it is possible to observe some attenuating effect of nitrogen in plants under saline stress. In this context, this review discusses the possibility of nitrogen fertilization to attenuate the effects of irrigation water salinity in maize.
