1. 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

5. Leaf area index and radiation extinction coefficient of a coffee canopy under variable drip irrigation levels
ABSTRACT. The leaf area index (LAI) is relevant in studies of phenomena at different scales, such as for the leaf to canopy scale and the calculation of the extinction coefficient of photosynthetically active radiation (kPAR), providing input for the parameterization of physiological basis models. The objective of this work was to verify the variation of the

7. Influence of organic mulching on drip irrigation management of cabbage cultivation
Resumo A irrigação tem sido apontada nas últimas décadas como o maior consumidor de água. Considerando a necessidade de um uso racional dos recursos hídricos e a importância da cobertura morta para o plantio, o objetivo deste estudo foi avaliar o efeito da cobertura morta orgânica (palha de cana-de-açúcar) sob o armazenamento de água no solo para

8. Modeling and hydraulic performance evaluation of a dripper device coupled to a branched water distribution network
Resumo A irrigação é responsável por aproximadamente 70% do consumo de água doce do mundo e é um dos principais fatores por trás da crescente escassez de água global. As técnicas e sistemas de irrigação são extremamente diferenciadas e complexas. Neste contexto, as ferramentas de dinâmica de fluidos computacional (CFD) ganham relevância, permit

10. MODELING SOIL WATER REDISTRIBUTION UNDER SURFACE DRIP IRRIGATION
ABSTRACT The main objective of this study was to develop a numerical model to simulate water distribution, and the shape of the wetted soil volume, resulting from a point source irrigation at the ground surface (dripper), given soil hydraulic properties and irrigation system parameters. The mathematical model was developed in Fortran 90 at the Department of

11. Winery distillery waste compost effect on the performance of melon crop under field conditions
ABSTRACT: The substantial generation of organic waste together with increasing interest in developing sustainable agriculture heralds an opportunity for mobilizing the recycling of these materials as a source of organic matter and nutrients into a viable management strategy option. A field experiment was conducted to evaluate the use of compost derived from

12. STATISTICAL PROCESS CONTROL IN THE ASSESSMENT OF DRIP IRRIGATION USING WASTEWATER
ABSTRACT The aim of this study was to evaluate drip irrigation as a process, by monitoring the average flow applied by the emitter using tools of statistical quality control. Four kinds of drippers were selected, two inline labyrinth type and two online where one of the inline emitters was not self-compensating and the other, self-compensating emitter. The s
