The gray water footprint (GWF) is defined as the volume of fresh water needed to dilute contaminants incorporated into the surface and subsurface layers of the soil, through the emission of agrochemicals in agricultural production. Therefore, the objective of this research was to evaluate the gray water footprint in tomato cultivation in Brazilian semiarid regions. The study was developed in the municipalities ...
Agricultural 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...
West 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...
This 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...
A ocorrência de longos períodos de estiagem e a irregularidade anual das precipitações no Semiárido do Nordeste brasileiro torna a prática da irrigação imprescindível para garantir a produção agrícola com segurança, no entanto, as fontes hídricas disponíveis nem sempre são de boa qualidade. Desta forma, objetivou-se avaliar os efeitos da irrigação com águas de distintos níveis salinos associado a doses de nitro...
The prevailing climate of the semiarid region in the northeastern region of Brazil along with inadequate irrigation management, have caused the formation of halomorphic soils, which have hampered agricultural production and environmental sustainability of this region. Therefore, this study aimed to evaluate the emergence and initial growth of the cotton cultivar ‘BRS Topázio’ cultivated in soil with different l...
A salinidade da água de irrigação pode afetar a exploração de cultivos principalmente nas regiões áridas e semiáridas, entretanto, algumas alternativas podem favorecer a exploração agrícola nestas condições. Desse modo, objetivou-se com este trabalho, avaliar a interação entre adubação nitrogenada e a salinidade da água de irrigação sob o crescimento de porta-enxerto de goiabeira ‘Crioula’ em condição de semiár...
