1. CALIBRATION AND TESTING OF CS-CROPGRO MODEL FOR COMMON BEANS
ABSTRACT: Simulation models of crop growth enable estimating crop yield and water balance components with low cost and high precision. This study aimed to calibrate and evaluate the performance of the CS-CROPGRO model for common beans under the conditions of Jaboticabal city (SP), Brazil. The model was calibrated and tested with data previously collected fro

2. A non-invasive plant-based probe for continuous monitoring of water stress in real time: a new tool for irrigation scheduling and deeper insight into drought and salinity stress physiology
The non-invasive, magnetic leaf patch clamp pressure probe (also termed ZIM-probe) allows for the first time to measure continuously turgor pressure changes of plant leaves over long periods of time with high precision and in real time. The probe has become an important tool in plant physiology, molecular biology and ecology, but also in agriculture because

3. Desenvolvimento de um controlador de irrigação para áreas experimentais / Development of an irrigation controller for experimental areas
Irrigation scheduling at experimental areas is determined by several factors, which are mainly related to features of each unit (container or bed) and criteria set by researchers. Many times the experimental areas are greenhouses and depending on the research may be necessary provide mechanisms for monitoring sensors and controlling actuators on each unit in

4. Método do tanque Classe A para irrigação da soja, cultivar Sambaíba, no Cerrado.
ABSTRACT: Efficient use of water resources is the key to guarantee suply for future human consumption and irrigation. In the irrigated areas of the Cerrado region pressurized irrigation systems allow high efficiency in water conduction. However, lack of knowledge in crop water requirement determine inadequated crop water management. Negative effect on crop d

7. Irrigação do cafeeiro no cerrado: estratégia de manejo de água para uniformização de florada.
ABSTRACT: The objective of this research was to define irrigation scheduling for coffee trees in the brazilian Cerrado region to optimize yield and coffee grain quality. The experimental treatments were: a) irrigation all over the year (RH1), suplemental water application after blossoming induced by rain (RH4), stop water application, at the harvesting time

8. Infrared thermometry to schedule irrigation of common bean.
The objective of this work was to determine the critical irrigation time for common bean (Phaseolus vulgaris L. cv. Carioca) using infrared thermometry. Five treatments were analyzed. Canopy temperature differences between plants and a well-watered control about 1, 2, 3, 4, and 5±0.5ºC were tested. Physiological variables and plant growth were analyzed to

11. Resposta da cultura de melão a diferentes intensidades e frequências de irrigação em Porto Nacional - TO
O Estado do Tocantins vem a cada dia recebendo mais investimentos públicos e privados para desenvolvimento da agricultura irrigada. Esse crescimento não está sendo acompanhado com o desenvolvimento suficiente de pesquisas e difusão de técnicas aplicáveis para irrigação nessa região. Esse trabalho é um experimento no município de Porto Nacional, re

12. Avaliação do sensor de umidade TOPDEA no manejo da irrigação. / Evoluation of the moisture sensor topdea for irrigation scheduling.
The scientific community, in recent years, has intensified studies to measure the impacts to the environment caused by pollution, mainly the adverse effects to air and water. The fact that less than 1% of the global water resources is comprised of drinking water and available at the surface of the earth makes it a commodity of conflict. According to the FAO
