EVALUATION OF METEOROLOGICAL ELEMENTS AND LETTUCE (Lactuca sativa, L.) YIELD RELATED TO GEOGRAPHIC ORIENTATION OF POLYETHYLENE GREENHOUSES   Cláudio Márcio Pereira de SouzaAntonio Evaldo Klar*Department of Agricultural Engineering, College of Agricultural Sciences, State University of São Paulo, P.O. 237, CEP 18603-970, Botucatu – SP. E-mail: [email protected]* Scientific Researcher of CNPqLuiza Helena DuenhasEMBRAPA Semi Árido, P.O. 23, CEP 56300–970, Petrolina – PE.   1 ABSTRACT  This experiment was carried out at the Agricultural Engineering Department, FCA/UNESP, Botucatu–SP aiming to study  the geographic orientation influence of two plastic tunnels (East/West and North/South based on the magnetic North) on lettuce plant (Lactuca sativa L, cv. Elisa) behavior and on the evaporation distribution uniformity inside the tunnels. The plants were sowed on 05/05/1999, transplanted on 05/29/1999 and harvested on 06/31/1999. Tensiometers were used to monitore soil water potentials. A drip irrigation system was used. Both tunnels received A Class pan and thermohygrographes in the center and 3 m apart small evaporimeters set at 3 heights (0.50 m, 1.00 m and 1.50 m). Through geostatistical analysis, there was not neither spatial dependency nor spatial variability of evaporation in both tunnels. However, the height of evaporimeters showed statistical differences: the 1.50 m height evaporimeter had slower evaporation than those from other heights. The air temperature, relative humidity and vapor pressure deficit averages were not statistically significant in both greenhouses when they were compared to those from the outside. A Class pan evaporation values were higher outside the tunnels than inside them, but there were no differences between both tunnels for this variable. The lettuce plant yield was not influenced by tunnel orientation, but there were significant differences on plant yield among beds inside each tunnel.  Keywords: evaporation, irrigation, greenhouse.   SOUZA, C. M. P., KLAR, A. E., DUENHAS, L. H. AVALIAÇÃO DE ELEMENTOS METEOROLÓGICOS E PRODUÇÃO DE ALFACE (Lactuca sativa L.) AFETADOS PELA ORIENTAÇÃO GEOGRÁFICA DE ESTUFAS DE POLIETILENO.   2 RESUMO  O experimento foi realizado na área experimental do Departamento de Engenharia Rural da Faculdade de Ciências Agronômicas – Unesp/Botucatu, Estado de São Paulo, em duas estufas dispostas em diferentes orientações geográficas, Leste/Oeste e Norte/Sul. A alface (Lactuva sativa L.) cv. Elisa foi cultivada em ambas estufas, sendo semeada em 05/05/99, transplantada em 29/05/99 e colhida em 31/06/99. Utilizou-se tensiômetros para monitorar o potencial de água no solo para realizar o manejo do sistema de irrigação por gotejamento. Microevaporímetros eqüidistantes de 3 m e colocados em 3 alturas, 0.50, 1.00 e 1.50 m, termohigrógrafos e tanques Classe “A” foram instalados nas duas estufas. Através de análise geoestatística, não se observou dependência espacial nem variabilidade espacial da evaporação nas duas estufas. Entretanto, a altura dos evaporímetros apresentou diferenças significativas: a evaporação à altura de 1.50 foi menor que nas outras duas.As médias de temperatura, umidade relativa e déficit de pressão de vapor do arnão diferiram estatisticamente entre as estufas e o ambiente externo. Os valores médios de evaporação de água no tanque Classe “A” instalado fora das estufas diferiram estatisticamente quando comparados com os instalados no interior das estufas, porém, entre as orientações não se constatou diferença significativa. Pôde-se verificar que não houve diferença significativa das características agronômicas da alface em ambas orientações estudadas. No entanto, houve diferença significativa para essas características entre os canteiros no interior das mesmas, havendo variância espacial para os dados de matéria fresca apenas na estufa N/S.  UNITERMOS: evaporação, irrigação, estufa.

The objective of this study was to evaluate the effect of different air velocities and temperature at the feeder on mean surface temperature of Japanese quail during the initial stage of laying. The experiment was carried out at the Center for Research in Environment and Agroindustry Systems Engineering (AMBIAGRO), Department of Agricultural Engineering, Federal University of Viçosa, Viçosa/MG, Brazil. A total of 216 Japanese quail in the initial laying phase were placed in four environmental chambers with different temperatures and air velocity, where they were housed and distributed randomly in 2 galvanized wire cages, with 3 partitions each and 27 birds/cage, and a density of approximately 155.6 cm²/bird. The experimental design consisted of randomized blocks with replications of two treatments (air velocity at the feeder: 0, 1, 2, and 3 m/s and air temperature: 17, 23, 29 and 35°C). The mean surface temperature was analyzed by Two-Way ANOVA, with treatment means separated by the Tukey test (P < 0.05). There was a significant positive correlation between air temperature and mean surface temperature (MST). Air velocity is important in removing heat from the surface of birds.

Abstract The International Conference on Environmental and Sustainability Context (ICoESCo) 2021 is the first international conference hosted by Environmental Sustainability Research Group (EnSi-RG) and co-hosted by Environmental Research Center, Lembaga Penelitian Universitas Trisakti, Environmental Engineering Department, Faculty of Engineering, Universitas Diponegoro, and Kitakyushu Indonesian Students’ Union. This conference was successfully held on August 24, 2021 which brings the theme of “Emerging Challenges and Opportunities for Achieving Environmental Sustainability” since the theme of “sustainability” has become the most crucial issue of the world by now. This conference was attended by 81 participants that came from 34 universities across the world which include as follows. List of ICOESCO 2021 Committees are available in this pdf.
