Water retention curve of coconut fiber substrate for cultivation in pots in gre...
Nascimento, Erlen Kaline Ávila do; Rego, Lunara Gleika da Silva; Miranda, Neyton de Oliveira; Figueirêdo, Vladimir Batista; Silva, Nathalia GomesA substrate with adequate porosity and water retention capacity makes it possible to maximize the yield and quality of crops produced in containers in greenhouses. A great alternative is coconut fiber, which needs careful irrigation management, which can be based on monitoring the water content in the root zone using tensiometers. In this sense, this work aimed to determine the water retention curve of coconut ...

Costa, Maria Eugênia da; Miranda, Neyton de Oliveira; Pimenta, Alexandre Santos; Nascimento, Erlen Kaline ÁvilaMaize is grown throughout Brazil and used for feeding humans and animals and as a raw material for biofuels and industry. Its yield is impaired by of soil and water degradation, such as salinization, which is more serious in semi-arid regions. Three experiments were carried out in different soils (Acrisol, Cambisol, and Fluvisol) of the state of Rio Grande do Norte with the objective of evaluating biochar effec...
Spatial variability of sunn hemp under residual effect of nitrogen and water sa...
Sampaio, Pedro Ramualyson Fernandes; Miranda, Neyton de Oliveira; Medeiros, José Francismar de; José, Jefferson Vieira; Lira, José Flaviano Barbosa deThis work had as objectives to use the Sunn Hemp (Crotalaria juncea L.) to evaluate the residual effect in the soil of levels of water salinity and nitrogen doses, and the occurrence of spatial dependence within the experimental area. In previous years, the experimental area received six consecutive trials, which tested different levels of nitrogen and water salinity on different crops. The same experimental de...
DOSES DE ESTERCO DE OVINOS E DE POLÍMERO HIDROABSORVENTE NO CULTIVO DE ARROZ EM...
Lima, Anna Carolina Carvalho de; Silva, Allisson Rafael Ferreira da; Maia, Francisco Emanuel Nogueira; Melo, Isabel Giovanna Costa eRESUMO - O objetivo do presente trabalho foi avaliar a produtividade do arroz e o consumo de água pela cultura após aplicação ao solo de doses de esterco de ovinos e de polímero hidroabsorvente. Os tratamentos foram aplicados em vasos, seguindo delineamento experimental inteiramente casualizado em esquema fatorial 4x3, com quatro repetições. Os fatores estudados foram doses de esterco de ovinos (0, 100 e 200 g ...
