2. Performance of cover crops under two irrigation regimes in the Coastal Tablelands region of Brazil
ABSTRACT There is currently a lack of information regarding the performance of cover crops grown in the Coastal Tablelands region in the North of the Brazilian state of Espírito Santo, where zero tillage is increasingly being adopted. The objective of this study was to evaluate the agronomic performance of six cover crops (ruzi grass, jack bean, and the mil

3. FUZZY MODELING OF THE EFFECTS OF DIFFERENT IRRIGATION DEPTHS ON THE RADISH CROP. PART I: PRODUCTIVITY ANALYSIS
ABSTRACT The productivity of a crop is related to the water demand inserted in its development. The measurement of water and its optimization directly influences the final costs of crop production for agricultural producers. In this sense, the objective of this study is evaluating the fuzzy modeling in estimating the productivity of the radish crop (fresh ph

4. TECHNICAL AND ECONOMIC FEASIBILITY OF USING A VARIABLE-FREQUENCY DRIVE IN MICRO-IRRIGATION SYSTEMS
ABSTRACT Irrigation is essential for the development of crops in regions with scarcity or irregular rainfall distribution, enabling high productivity. However, the use of water resources and electrical energy leads to a concern with irrigation efficiency. Pressure demand varies during the operations of irrigation systems and the appropriate pressure can be r

5. ACHPA: A sensor based system for automatic environmental control in hydroponics
Abstract The trend towards tunnel farming and hydroponic systems is increasing owing to the climatic changes as well as the need to increase crop yield. Hydroponic is a technique of growing plants without soil. Tunnel farming and hydroponic system requires controlled environmental parameters like temperature, humidity and soil moisture for better production

6. ASYMMETRIC WETTED SECTOR ANGLE IN WATER DISTRIBUTION OF TRAVELING GUN IRRIGATION SYSTEMS
ABSTRACT This work aimed to simulate the water distribution of traveler gun irrigation, working with asymmetrical wetted angles and in windy conditions. In the simulations of a sprinkler with uniform radial profile, the following were considered: i) wetted angles between 180 and 330°; ii) wetted angle asymmetries from 0 to 90°; iii) wind speeds from 0 to 4

7. Comparison of automated irrigation systems using an in vitro ureteroscopy model
ABSTRACT Introduction: Two automated irrigation systems have been released for use during endoscopic procedures such as ureteroscopy: the Cogentix RocaFlow® (CRF) and Thermedx FluidSmart® (TFS). Accurate pressure control using automated systems may help providers maintain irrigation pressures within a safe range while also providing clear visualization. O

8. Editorial Comment: Comparison of automated irrigation systems using an in vitro ureteroscopy model
ABSTRACT Introduction: Minimally invasive treatments such as extracorporeal shock wave lithotripsy and percutaneous nephrolithotripsy are standard procedures for the management of renal stones (1). However, renal position and rotation defects may significantly interfere in the results of these treatments (2). Open surgery has always been an option for these

10. Bioactive compounds in edible flowers of garden pansy in response to irrigation and mycorrhizal inoculation
ABSTRACT Edible flowers have been increasingly used in the Brazilian gastronomy because they are considered functional foods with high antioxidant potential. Studies on the management of cultivation of edible flowers to increase the production of bioactive compounds have been developed aiming at the improvement of production systems. The objective of this wo

12. Potencialidade de uso não potável de água de lagoa de detenção
RESUMO As águas de lagoas de detenção geralmente não são utilizadas produtivamente e o seu potencial é desperdiçado. Por estarem disseminadas nas cidades, a utilização dessas águas pode reduzir os custos com transporte de água, além de permitir a preservação de águas de melhor qualidade para fins mais nobres. Algumas das possíveis utilizaçõ
