Arugula cultivation under saline water irrigation
Moreira Neto, Antonio; Gonçalves dos Santos, César; Santos, Alex Béu; Silva, José Carlos Santos; Reis, Lígia SampaioThe use of saline water in the production of vegetables is one of the main challenges for producers, since salt stress causes a decrease in crop production and yield. In this context, this study aimed to evaluate the growth of arugula plants under irrigation water salinity levels. The experiment was carried out in a greenhouse, with treatments being five levels of electrical conductivity of the irrigation water...
WEED CONTROL BY SOLARIZATION AND MULCHING IN COWPEA DEVELOPMENT
Maia Júnior, Sebastião de Oliveira; Andrade, Jailma Ribeiro de; Reis, Lígia Sampaio; Santos, Claudiana Moura dos; Silva, Lennon Kledson dos SantosWeeds are a serious threat to agriculture because they compete with crops, thereby interfering in production. As such, this study aimed to assess weed control using soil solarization and mulching on the growth and yield of cowpea. A completely randomized design was used, with eight treatments and four repetitions. The treatments consisted of a combination of two management practices, namely soil solarization (w...
