Growth and biomass production of prickly pear in the second cycle irrigated wit...
Azevedo Junior, Manoel Simões de; Ferreira Neto, Miguel; Medeiros, José Francismar de; Sá, Francisco Vanies da Silva; Lima, Yuri Bezerra deThis study aimed to evaluate, in the second cycle, the growth and production of ‘Orelha-de-elefante Mexicana’ prickly pear (Opuntia sp.) under complementary irrigation with treated domestic sewage. The experiment was carried out in the Milagre Settlement, municipality of Apodi-RN, Brazil, from June 2016 to February 2017. Five treatments were evaluated, corresponding to four irrigation frequencies (2.3, 7.0, 14....
Ethnopedology in production units at Canto da Ilha de Cima, São Miguel do Gosto...
Cunha, Marialdo Santana da; Ferreira Neto, Miguel; Portela, Jeane Cruz; Ernesto Sobrinho, Francisco; Silva, Jucirema Ferreira da; Dias, Nildo da SilvaEthnopedological studies in family units tend to contribute to the academy with respect to the importance of knowledge exchange, allowing the understanding on the local reality of a community. The objective of this study was to conduct an ethnopedological study in production units at the Settlement Project Canto da Ilha de Cima – RN, Brazil, and to infer on their interrelationships of knowledge. Participatory w...
Physiology and yield of piel de sapo melon (Cucumis melo L.) under water defici...
Melo, Alberto Soares de; Dias, Vandeir Gouveia; Dutra, Wellison Filgueiras; Dutra, Alexson Filgueiras; Sá, Francisco Vanies da SilvaMelon (Cucumis melo L.) is a crop of great socioeconomic importance in regions with semiarid climate, as found in Northeast Brazil. In this region water deficit is a usual condition as well as the main reduction factor of plant productivity. Due to this phenomenon, irrigation techniques are used to make available the amount of water needed for plant production. Therefore, this research evaluated the physiology ...
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...
Nutrient support via fertigation with domestic effluent and growth of cotton
Gonçalo Filho, Francisco; Ferreira Neto, Miguel; Fernandes, Cleyton dos Santos; Sá, Francisco Vanies da Silva; Dias, Nildo da SilvaBecause of climatic problems in the Brazilian semi-arid region, it is of fundamental importance to seek a culture that considers water scarcity and available natural resources. Thus, a randomized block design, with subdivided plots and six replications, was carried out in the experimental area of the treatment and wastewater reuse station of the Milagres Settlement, Apodi, Brazil, with the objective of evaluati...
Tolerance of seedlings traditional varieties of cowpea (Vigna unguiculata) to s...
Praxedes, Saulo Samuel Carneiro; Sá, Francisco Vanies da Silva; Ferreira Neto, Miguel; Loiola, Aline Torquato; Reges, Layla Bruna LopesCowpea is an important source of protein, being the main subsistence crop in the northeast region of Brazil, where water restriction and salinity are limiting factors. Identification of saline stress tolerant varieties can aid crop expansion and improve crop yields. The objective was to study the tolerance of traditional varieties of cowpea to the salinity of irrigation water in the emergency and initial growth...
Ecophysiology of west indian cherry irrigated with saline water under phosphoru...
Sá, Francisco Vanies da Silva; Gheyi, Hans Raj; Lima, Geovani Soares de; Paiva, Emanoela Pereira de; Silva, Luderlândio de AndradeThe quantitative and qualitative scarcity of water resources is a frequent problem in the semi-arid region of the Brazilian Northeast. The availability of water for irrigation with high salts contents is common, affecting the growth and development of the crops. Thus, it is necessary to adopt strategies that allow the establishment of irrigated cultivation in this region. The objective of this work was to evalu...
Germination and osmotic adjustment in Salvia hispanica L. (Lamiaceae) seedlings...
Paiva, Emanoela Pereira de; Torres, Salvador Barros; Oliveira, Renata Ramayane Torquato; Sá, Francisco Vanies da Silva; Leite, Moadir de SousaSalvia hispanica seedlings have stood out for their potentialities in nutrients for agri-food industries. Nevertheless, studies related to this species are still scarce, especially with respect to agronomic factors that enable its propagation and development. Hence, this study aimed to evaluate germination, vigor and osmotic adjustment of S. hispanica seeds and seedlings subjected to water and thermal stress. T...
Growth and physiology of Annona squamosa L. under different irrigation depths a...
Moreira, Rômulo Carantino Lucena; Brito, Marcos Eric Barbosa; Fernandes, Pedro Dantas; Sá, Francisco Vanies da Silva; Silva, Luderlândio de AndradeThis study aimed to evaluate the growth and physiology of Annona squamosa seedlings under increasing irrigation depths and phosphorus doses. The experiment was conducted in protected environment, evaluating five irrigation depths and four P2O5- doses, arranged in 5 x 4 factorial scheme, in randomized blocks, with four replicates and one plant per plot. Treatments were irrigation depths of 60, 80, 100, 120 and 1...
Yield and quality of cherry tomato fruits in hydroponic cultivation
Dias, Nildo da Silva; Diniz, Adriana Araújo; Morais, Patrícia Ligia Dantas de; Pereira, Gledyson Dos Santos; Sá, Francisco Vanies da SilvaBecause of the food and industrial importance of tomato, it holds great significance, and is one of the most produced species using the hydroponic cultivation systems. The objective of this study was to evaluate the effects of different concentrations of nutrient solution on the production and quality of cherry tomatoes (Lycopersicon esculentum ‘Samambaia’) grown in a hydroponic system in protected conditions. ...
