Chloroplast pigments and photochemical efficiency of West Indian cherry under s...
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...
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...
Saline water and potassium fertilization in cultivation of grafted west indian ...
Pinheiro, Francisco Wesley Alves; Lima, Geovani Soares de; Gheyi, Hans Raj; Dias, Adaan Sudário; Moreira, Rômulo Carantino LucenaAgricultural exploitation in the semi-arid region of Northeast Brazil depends on the use of irrigation to guarantee safe production of crops. Nevertheless, the waters commonly used in this region have high levels of salts and require management strategies that make their use possible in agriculture. In this context, the present study aimed to evaluate water relations, photosynthetic pigments and growth of graft...
Water salinity and nitrogen fertilization in the production and quality of guav...
Bezerra, Idelfonso Leandro; Gheyi, Hans Raj; Nobre, Reginaldo Gomes; Lima, Geovani Soares de; Lacerda, Claudivan Feitosa deUsing nitrogen (N) to increase plant tolerance to salinity has been tested in many species. However, in addition to controversial results, most studies are conducted with annual species and/or in the initial growth stage and there are almost no studies with perennial fruit crops in the production stage. Thus, this study aimed to evaluate the production components and post-harvest quality of ‘Paluma’ guava irrig...
Gas exchanges and production of West Indian cherry cultivated under saline wate...
Lima, Geovani Soares de; Pinheiro, Francisco Wesley Alves; Dias, Adaan Sudário; Gheyi, Hans Raj; Nobre, Reginaldo GomesWest Indian cherry is of great socioeconomic importance to Brazil because of its potential to keep local workers in rural areas and generate income. It is mainly cultivated in the Northeast region, where high salt concentrations are common in water. This study was conducted to evaluate gas exchanges and production of West Indian cherry cultivar (cv.) ‘BRS 366 Jaburu’, as a function of irrigation with water of d...
Formation of soursop seedlings irrigated using waters with different salinity l...
Veloso, Luana Lucas de Sá Almeida; Nobre, Reginaldo Gomes; Souza, Leandro de Pádua; Gheyi, Hans Raj; Saldanha Cavalcante, Ilana TaynanUsing saline waters in agriculture has become common in many regions worldwide, but some techniques have been developed to enable the use of these waters in order not to harm the crop. Thus, this study aimed to evaluate the growth of soursop seedlings, cv. 'Morada Nova', under interaction between salt stress and nitrogen (N) fertilization. The experiment was conducted in a greenhouse in randomized block design,...
NPK and sodium content in sesame under salt stress and nitrate/ammonium fertili...
Dias, Adaan Sudário; Lima, Geovani Soares de; Gheyi, Hans Raj; Nobre, Reginaldo Gomes; Souza, Leandro de Pádua; Anjos Soares, Lauriane Almeida dosThis study aimed to evaluate the effects of saline water irrigation and fertilization with different nitrate/ammonium proportions on the contents of nitrogen (N), phosphorus (P), potassium (K+) and sodium (Na+) and Na+/K+ ratio in the sesame cv. CNPA G3, through an experiment conducted in drainage lysimeters under greenhouse conditions, in eutrophic Regolithic Neosol with sandy loam texture, in the municipality...
CRESCIMENTO DE PORTA-ENXERTO DE GOIABEIRA cv. PALUMA IRRIGADA COM ÁGUAS SALINAS...
Sena, Guilherme Sá Abrantes de; Nobre, Reginaldo Gomes; Souza, Leandro de Pádua; Araújo, Sarah Carolina Alves; Silva, Israel Almeida daA escassez de água de boa qualidade e a ocorrência de solos com baixa fertilidade são fatores limitantes para a agricultura irrigada, principalmente em regiões áridas e semiáridas, o que induz a utilização de águas salinas e adubação nitrogenada como alternativas para a produção agrícola nessas regiões. Desta forma, objetivou-se avaliar a in?uência de doses de nitrogênio no crescimento de mudas de goiabeira cv....
