Dias, Adaan Sudario; Lima, Geovani Soares de; Gheyi, Hans Raj; Furtado, Guilherme de Freitas; Soares, Lauriane Almeida dos Anjos; Nobre, Reginaldo GomesThe objective of this study was to evaluate chloroplast pigments and photochemical efficiency of West Indian cherry cv. BRS 366 Jaburu as a function of irrigation water salinity and potassium-phosphorus fertilization combinations in the second year of cultivation. The experiment was carried out in a protected environment in Campina Grande, Brazil. Treatments were distributed in randomized blocks, in a 5 × 4 fac...
Gas exchange, growth, and quality of passion fruit seedlings cultivated with sa...
Lima, Geovani Soares de; Andrade, José Nathanael Ferreira de; Medeiros, Mizael Nabor Vaz de; Soares, Lauriane Almeida dos Anjos; Gheyi, Hans RajThis study was conducted to evaluate the gas exchange, growth, and quality of passion fruit cultivars under irrigation with waters of different salinity levels. The experiment was conducted in a greenhouse, in Pombal-PB, Brazil, using a randomized block design in a 5 ? 2 factorial arrangement, with five levels of electrical conductivity of irrigation water (0.3, 1.1, 1.9, 2.7, and 3.5 dS m-1) and two passion fr...

Paiva, Francisco Jean da Silva; Lima, Geovani Soares de; Lima, Vera Lúcia Antunes de; Ramos, Jailton Garcia; Gheyi, Hans RajThe 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), Camp...
Growth and production of ornamental sunflower irrigated with dilutions of treat...
Gonçalves, Karoline Santos; Bispo, Gustavo Araújo; Bandeira, Samir de Sousa; Gheyi, Hans Raj; Paz, Vital Pedro da SilvaThe water and nutritional potential of wastewater has been frequently exploited as an alternative water source for the irrigation of crops, especially in regions affected by the scarcity of water resources. Thus, this study aimed to evaluate growth and production of ornamental sunflower (Helianthus annuus L.) cv. Anão de Jardim irrigated with different dilutions of treated domestic sewage in public-supply water...
Salt stress on physiology, biometry and fruit quality of grafted Passiflora edulis
dos Santos Moura, Regiana; Gheyi, Hans Raj; da Silva, Everaldo Moreira; Dias, Elisson de Araújo; da Cruz, Caliane Silva; Coelho Filho, Mauricio AntônioThe production of grafted passion fruit is an alternative for plant adaptation to saline environments. The objective of this study was to evaluate the effect of salt stress on physiology, biometry and fruit quality of P. edulis grafted on Passiflora spp. The experiment was conducted in completely randomized design, in a 3 x 2 factorial scheme, corresponding to three species of Passiflora (P. edulis, P. gibertii...
Fruit quality of west indian cherry irrigated with saline waters under combinat...
Silva, Evandro Manoel da; Gheyi, Hans Raj; Nobre, Reginaldo Gomes; Barbosa, Joicy Lima; Santos, Bárbara Genilze Figueiredo LimaWest Indian cherry stands out among the fruits cultivated for the pharmacological and alimentary importance, but its quality can be affected by irrigation water salinity and fertilization management. In this context, this research aimed to study the effect of irrigation water of different salinities and combinations of nitrogen and potassium fertilization on the physical and physico-chemical quality of bioactiv...
Saline stress and exogenous application of proline in cashew rootstck
Souza, Leandro de Pádua; Nobre, Reginaldo Gomes; Gheyi, Hans Raj; Fatima, Reynaldo Teodoro de; Barbosa, Joicy LimaThe scarcity of good quality water and the occurrence of long dry periods are limiting factors for irrigated agriculture, especially in semiarid regions, which induces the use of saline water and technologies that enable its use in agriculture. In this context, the objective of the present study was to evaluate the influence of exogenous application of proline on growth and phytomass of BRS 226 Planalto precoci...
Cultivation of West Indian cherry irrigated with saline water under phosphorus ...
Sá, Francisco Vanies da Silva; Gheyi, Hans Raj; Lima, Geovani Soares de; Ferreira Neto, Miguel; Paiva, Emanoela Pereira deThe objective of this work was to evaluate the effect of water salinity and phosphorus:nitrogen ratios on growth, leaf macronutrients and sodium and the West Indian cherry production. The research was carried out in a protected environment, in lysimeters filled with a Regolithic Neosol of loamy clay texture and low initial phosphorus content. The experiment was carried out in a protected environment, in a rando...
Production and quality of watermelon fruits under salinity management strategie...
Silva, Saulo Soares da; Lima, Geovani Soares de; Lima, Vera Lúcia Antunes de; Gheyi, Hans Raj; Soares, Lauriane Almeida dos AnjosThe objective of this study was to evaluate the production and quality of ‘Sugar Baby’ watermelon fruits under different strategies of irrigation with saline water and nitrogen (N) fertilization in an experiment conducted in a protected environment in Campina Grande, Paraíba, Brazil. The experimental design adopted was in blocks with a 6 × 2 factorial scheme, corresponding to six strategies of irrigation with s...
Gas exchange, growth, and production of mini-watermelon under saline water irri...
Lima, Geovani Soares de; Félix, Charles Macedo; Silva, Saulo Soares da; Soares, Lauriane Almeida dos Anjos; Gheyi, Hans RajIn the semi-arid region of northeastern Brazil, due to the occurrence of excess salts, both in the water and soil, plants are constantly exposed to various conditions of abiotic stress. Thus, it is extremely important to identify methods capable of minimizing the effects of salt stress on plants as a way to ensure the expansion of irrigated areas. In this context, the objective of this study was to evaluate the...
