“…Many authors have also observed that evapotranspiration inside a greenhouse is around 60 to 80% of that verified outside (Rosenberg et al, 1989). Farias et al, (1994) observed that the reference evapotranspiration (Et 0 ) inside greenhouses was always lower, ranging on 45 to 77% of that verified outside.…”

“…Portanto, para as condições deste experimento, recomenda-se a instalação do tanque "Classe A" dentro da casa de vegetação. Sugere-se, ainda, a utilização de Kp = 1,0, pois, nessas condições, os valores da ETo estimados foram semelhantes aos encontrados por outros autores (MONTERO et al, 1985;ROSENBERG et al, 1989e FARIAS et al, 1994.…”

“…Em geral, a evapotranspiração no interior da casa de vegetação fica em torno de 60 a 80% daquela verificada no exterior (MONTERO et al, 1985;ROSENBERG et al, 1989). FARIAS et al (1994) verificaram que a evapotranspiração de referência (ETo) no interior da casa de vegetação foi sempre menor, ficando entre 45 e 77% da verificada na parte externa.…”

RESUMO:O trabalho teve como objetivos estimar a evapotranspiração de referência (ETo) dentro e fora de casa de vegetação, pelo método do tanque "Classe A", utilizando-se de dois valores de Kp e estabelecer correlações entre a ETo, dentro e fora da casa de vegetação, buscando evitar a instalação do tanque "Classe A" dentro da mesma. O experimento foi conduzido na Faculdade de Ciências Agrárias e Veterinárias, Câmpus de Jaboticabal -SP. Instalaram-se dois tanques "Classe A", um dentro e outro fora da casa de vegetação. Para o tanque instalado dentro da casa de vegetação, utilizaram-se dois coeficientes de tanque: Kp = 0,7 e Kp = 1,0. Para o tanque instalado fora da casa de vegetação utilizou-se Kp = 0,85. Constatou-se que a ETo dentro da casa de vegetação foi menor que a estimada fora da mesma. Recomenda-se a instalação do tanque "Classe A" dentro da casa de vegetação para a estimativa da ETo, utilizando-se de Kp = 1,0. PALAVRAS-CHAVE: evapotranspiração de referência, coeficiente de tanque. THE CLASS A PAN METHOD TO ESTIMATE THE REFERENCE EVAPOTRANSPIRATION INSIDE A GREENHOUSE SUMMARY:The objective of this work was to compare the reference evapotranspiration (ETo) estimated by the class A pan installed inside and outside the greenhouse, using two Kp values. The experiment was conducted at the Faculdade de Ciências Agrárias e Veterinárias, Campus de Jaboticabal, Brazil. Two class A pans were installed, one inside and other outside the greenhouse. For the class A pan installed inside the greenhouse were used two Kp values, Kp = 0.7 and Kp = 1.0. For the class A pan installed outside the greenhouse was used Kp = 0.85. The value of the ETo inside the greenhouse was lower when compared to the one outside the greenhouse. The results of this work showed the need of using the class A pan inside the greenhouse, using Kp = 1.0.

“…Similarly, the strawberry grower (site 3) produced strawberries in an open field (zone 4) as well as under plastic high tunnels (zone 5), and both management practices were monitored. Crop water requirements are recognized to be approximately 30% lower in production systems under a high tunnel (Monterro et al, 1985;Rosenberg et al, 1989;Fernandes et al, 2003;Harmanto et al, 2005). It was therefore relevant to compare how water requirements were met by the participant producer in these different production systems.…”

For high-value horticultural crop production in southern Ontario, irrigation is an essential ingredient in overcoming insufficient rainfall and achieving stabilized crop production. In a context where competition for limited water resources intensifies due to the expansion of the agricultural sector, increasing urban development and tourism, and potential climate change impacts, conserving water through efficient irrigation has become a key solution in addressing this growing challenge. The implementation of advanced soil water monitoring technologies and water budgeting methods for improved irrigation scheduling is examined with regard to water conservation and thus as a means to cope with competing demands for limited water supplies. During the 2007 growing season, soil moisture was measured using two sensors at four field sites (comprising a total of six irrigated zones as two sites include two different irrigation/production systems) in southern Ontario. Irrigation water consumption was measured by flow meters at three sites. In addition, a survey was administered to collect information on growers' current irrigation scheduling practices. On-farm irrigation performance was assessed by comparing calculated tomato, green bell pepper, strawberry and peach water requirements (using the water budget method) with growers' estimates of irrigation water use and with soil moisture measurements taken during the growing season. Four out of the six irrigated zones were excessively irrigated, while in one zone, water was insufficiently applied. The crop water requirements were met efficiently exclusively in one zone where tomatoes were grown. Overall, the results of this research show that by implementing advanced soil moisture monitoring technologies, growers can increase precision in water application and reduce the uncertainty in their current irrigation scheduling practices.Résumé : Dans le sud de l'Ontario, l'irrigation est essentielle à la production de cultures horticoles à haute valeur ajoutée afin de compenser l'insuffisance de précipitations et stabiliser la production des cultures. Dans un contexte où la compétition pour les ressources limitées en eau s'intensifie en réponse à l'expansion du secteur agricole, à la croissance du développement urbain et du tourisme, ainsi qu'aux impacts potentiels des changements climatiques, conserver l'eau grâce à des techniques d'irrigation économes est devenue une solution incontournable pour affronter ce défi grandissant.
