O delineamento experimental foi em blocos casualizados, adotando o esquema fatorial 2 x 5 x 2, referente a dois genótipos de maracujazeiro amarelo (genótipo local tradicionalmente cultivado na cidade de Nova Floresta Paraíba, conhecido por Guinezinho e o genótipo BRS Gigante Amarelo), cinco níveis de salinidade da água de irrigação de 0,3; 1,0; 2,0; 3,0 e 4,0 dS m-1, no solo sem e com esterco líquido fermentado de bovino. As variáveis analisadas foram índice de velocidade de emergência, emergência, altura, diâmetro caulinar, área foliar, massa seca da raiz e da parte aérea das mudas e índice de qualidade de Dickson. O biofertilizante líquido de bovino proporcionou a formação de mudas de qualidade adequada ao plantio, em ambos os genótipos de maracujazeiro amarelo, comparadas às obtidas no solo sem o respectivo insumo, independentemente do nível de salinidade das águas de irrigação. Palavras-chave: Passiflora edulis, estresse salino, insumo orgânico.  MEDEIROS, S.A.S; CAVALCANTE, L.F.; BEZERRA, M.A.F.; NASCIMENTO, J.A.

The experimental design was in randomized blocks adopting a factorial design 2 x 5 x 2 referring to two genotypes of yellow passion fruit (Local genotype known as Guinezinho and BRS Yellow Giant genotype), five levels of water salinity irrigation of 0.3; 1.0; 2.0; 3.0 and 4.0 dS m-1 in soil with and without fermented liquid cattle manure. The variables analyzed were emergency speed index, emergency, plants height, stalk diameter, root dry mass and shoot, leaf area, and Dickson quality index. The liquid cattle biofertilizer provided the formation of seedlings with suitable quality for plantation, in both  passion fruit genotypes compared to those obtained on the substrate without biofertilizer, regardless of the salinity of irrigation water. Keywords: Passiflora edulis, salt stress, organic input.

ABSTRACT In arid and semi-arid regions, the quality of irrigation water varies in geographic terms and during the year, and the occurrence of water with high concentrations of salts is common. In this context, this study aimed to evaluate the emergence, growth and production of sesame, cultivar CNPA G3, irrigated with saline water and fertilized with N of different carrier proportions by the ratio of nitrate and ammonium ( NO --N and NH +-N) in an experiment conducted in lysimeters arranged in a greenhouse in the municipality of Campina Grande-PB, Brazil. The treatments were distributed into randomized blocks using a 5 × 5 factorial scheme relative to levels of irrigation water salinity (ECw; 0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) and five proportions of NO3 -N/NH4 -N (200/0; 150/50; 100/100; 50/150 and 0/200 mg of N kg-1), with three replicates. The increase in ECw compromised the emergence, growth and production of sesame, cultivar CNPA G3, and the production components were the most sensitive variables. The highest growth in diameter was obtained with the proportion of 200/0 mg kg -1 of NO3 -N/NH4 -N. An ECw level of 3.0 dS m and fertilization with 0/200 mg kg of NO3 -N/NH4 -N promoted deleterious effects on the total mass of sesame fruits and mass of seeds. The interaction between water salinity levels and NO3-/NH4 proportions significantly affected the number of leaves (at 50 and 70 days after sowing), the total mass of fruits and the mass of seeds.

[email protected]   1 RESUMO A qualidade do tomate está diretamente relacionada com a qualidade da água utilizada na irrigação e com o suprimento adequado de nutrientes, principalmente o potássio e o cálcio. Este trabalho foi desenvolvido em ambiente protegido na UFERSA, em Mossoró, RN, com o objetivo avaliar a qualidade do tomate em função de diferentes relações iônicas de potássio e cálcio (K+/Ca2+), sendo: F1=1,5:1; F2=1,25:1; F3=1:1; F4=1:1,25 e F5=1:1,5 e quatro níveis de salinidade da água de irrigação (S1-0,5; S2-2,0; S3-3,5 e S4-5,0 dS m-1). O delineamento experimental utilizado foi em blocos casualizados, em esquema fatorial 5 x 4, totalizando 20 tratamentos, com quatro repetições. A relação K+/Ca2+=1:1 correspondente a concentração desses nutrientes recomendada para a cultura em cultivo de tomateiro hidropônico. Foram avaliadas as variáveis relacionadas a qualidade de frutos (sólidos solúveis, vitamina C, acidez titulável, pH e relação AT/SS). O uso de água com salinidade entre 2,0 e 3,5 dS m-1 aumenta a qualidade do tomate pelo aumento da razão SS/AT. As fertirrigações com maiores concentrações de K favorecem a qualidade dos frutos para salinidades até 3,5 dS m-1, mas não afetam a qualidade de tomate na salinidade 5,0 dS m-1. Palavras-chave: solanáceas, uso de águas salinas, potássio, cálcio  PAIVA, F.

PQUALITY OF TOMATO AS FUNCTION OF IRRIGATION WATER SALINITY AND K/CA RATIO IN FERTIGATION  2 ABSTRACT The quality of tomato is directly related to the quality of the water used in irrigation and to the adequate supply of nutrients, mainly potassium and calcium. The objective of this work was to evaluate the quality of tomatoes as a function of the different ionic ratios of potassium and calcium (K+/ Ca2+), with: F1 = 1.5:1; F2 = 1.25:1; F3 = 1: 1; F4 = 1:1.25 and F5 = 1:1.5 and four irrigation water salinity levels (S1-0.5, S2-2.0, S3-3.5 and S4-5.0 dS m-1). The experimental design was a randomized complete block design in a 5 x 4 factorial scheme, totaling 20 treatments, with four replications. The K+/Ca2+ ratio = 1:1 corresponds to the concentration of these nutrients recommended for cultivation in a hydroponic tomato crop. The variables related to fruit quality (soluble solids, Vitamin C, titratable acidity, pH and AT / SS ratio) were evaluated. The use of water with salinity between 2.0 and 3.5 dS m-1 increases tomato quality by increasing the SS/AT ratio. Fertigation with higher concentrations of K favor fruit quality at salinity up to 3.5 dS m-1, but do not affect tomato quality at 5.0 dS m-1 salinity. Keywords: solanaceae, use of salt water, potassium, calcium

Irrigation Water Salinity

Salinity is a major problem affecting agriculture in many regions of the world, including Morocco. The best agronomic practices such as fertilization are used to cope with salinity stress and improve productivity under saline conditions. The objective of this study is to evaluate the interactive effect of phosphorus and salinity on sugar beet (Beta vulgaris L.) cv. “Sporta” productivity and quality. A field experiment was carried out, testing three levels of irrigation water salinity (ECw = 0.7; 4, 8, and 12 dS·m−1) and three levels of phosphorus (100, 120, and 140 kg P2O5·ha−1) organized in a split-plot design with three replicates. This research was conducted in the Tadla region (center of Morocco) during two seasons in 2019 and 2020. The obtained results show that irrigation water salinity had a negative effect on most growth and productivity parameters. For instance, sugar beet yield reduced by 21% and by 26% under saline irrigation, with an EC value equal to 4 and 8 dS·m−1, respectively, compared to the control during the 2018-2019 season, and by 1%, 19%, and 27% under saline irrigation, with an EC value equal to 4 and 8 and 12 dS·m−1, respectively compared to the control (0.7 dS·m−1) during the 2019-2020 season. Total sugar content was significantly increased by 5% and 7%, respectively, under saline irrigation, with an EC value of 4 and 8 dS·m−1, respectively, as compared with the control in the first growing season in 2018-2019. However, in the second growing season (2019-2020), only the highest level of saline water (EC = 12 dS·m−1) significantly increased in sugar content by 15% compared to the control. Regarding the P fertilization effect, it was found that a P rate of 120 kg P2O5·ha−1 was enough to improve the yield and sugar content of sugar beet under the tested salinity levels. Thus, P fertilization could be one of the best practices to enhance sugar beets’ tolerance of salinity. To obtain a maximum root and sugar yield under saline water, it is recommended to apply a phosphorus dose of 120 kg P2O5·ha−1.
