1. Water availability and substrate in the emergency and initial development of Bauhinia scandens L.
ABSTRACT Bauhinia scandens is an ornamental plant and it has anti-tumor properties. The demand for seedlings of this species makes it necessary to know about the germinative behavior of seeds and the initial growth of seedlings. The objective of the present work was to determine the type of substrate and moistening conditions that are more favorable to the e

2. Response of bell pepper to water replacement levels and irrigation times
RESUMO Diferentes horários de irrigação resultam em diferentes taxas de transpiração, devido à disponibilidade de água e sua interação com a demanda evapotranspirativa. O déficit de pressão de vapor é um indicador preciso da capacidade evaporativa da atmosfera e pode afetar as plantas, devido ao movimento da água no sistema contínuo solo-planta

3. Yield and water use efficiency of cowpea under water deficit
RESUMO O estado do Pará é o maior produtor regional de feijão caupi, mas a produtividade alcançada ainda fica abaixo de outros estados da região Norte como Amazonas e Tocantins, devido ao manejo adotado e ao regime hídrico durante a safra, uma vez que seu cultivo é realizado em regime de sequeiro. Objetivou-se neste trabalho avaliar como a deficiênci

4. CLIMATOLOGICAL WATER BALANCE WITH DATA ESTIMATED BY TROPICAL RAINFALL MEASURING MISSION FOR THE DOCE RIVER BASIN
ABSTRACT The Climatic Water Balance (CLIMWB) is very used in the climatic characterization and can also offer important contribution in the identification of the water demand for irrigation of a region. For this, reliable precipitation data with good spatial coverage is required. The Tropical Rainfall Measuring Mission satellite -TRMM-3B43-v7 is a partnershi

5. SOIL SOLUTION DISTRIBUTION IN SUBSURFACE DRIP IRRIGATION IN SUGARCANE
Abstract Given the lack of studies on subsurface drip irrigation in sugarcane plantations, there has been a growing demand for such information, mainly regarding soil solution profile and availability to plants. Thus, this study aimed to evaluate the effects of soil-water solution distribution on qualitative and quantitative traits of sugarcane irrigated by

6. CHANGES IN SOIL CHEMICAL PROPERTIES PROMOTED BY FERTIGATION WITH TREATED SANITARY WASTEWATER
ABSTRACT We evaluate the application of treated sanitary wastewater (TSW) to provide potassium for crops and reduce demand for fresh water and mineral nutrients. The field experiment was arranged in randomized block design with four replications and five treatments: 50, 100, 150 and 200% of potassium requirements and a control with conventional fertilizer. T

7. Tissue culture of ornamental cacti
Cacti species are plants that are well adapted to growing in arid and semiarid regions where the main problem is water availability. Cacti have developed a series of adaptations to cope with water scarcity, such as reduced leaf surface via morphological modifications including spines, cereous cuticles, extended root systems and stem tissue modifications to i

8. Efficiency of water application of irrigation systems based on microsprinkling in banana plantations
Further food production may be limited by the reduced availability of water resources. Since irrigated agriculture is the productive sector that presents a higher demand of water, this sector has been under intense pressure in order to ensure food production with improved efficiency of water use. This study aimed to use the Time Domain Reflectometry (TDR) te

9. Química Sem Fronteiras: o desafio da energia
Coal, natural gas and petroleum-based liquid fuels are still the most widely used energy sources in modern society. The current scenario contrasts with the foreseen shortage of petroleum that was spread out in the beginning of the XXI century, when the concept of "energy security" emerged as an urgent agenda to ensure a good balance between energy supply and

11. Aproveitamento de água de chuva no meio urbano e seu efeito na drenagem pluvial
There is an increasing interest from the society in rainwater harvesting and use in urban areas, due to the benefits that this practice provides, such as: economic, environmental and urban flooding control. This interest may be perceived by the emergence of government regulations and increased availability of specific products in the domestic market for the

12. Cobertura morta de milho na umidade do solo e produtividade do feijoeiro irrigado em sistema plantio direto na região de Campinas-SP / Maize mulching in the soil moisture and productivity of irrigated dry bean under no-tillage system in Campinas-SP
Due to the potential of the no-tillage system (SPD) in the water and soil conservation combined with the need for research with irrigated crops in this system, mainly in the State of São Paulo, has been increasing the demand for information to minimize the degradation of hydrical resources, inappropriately used in the search for higher productivities.
