N sources affect growth, nutrient content, and net photosynthesis in maté (Ilex paraguariensis St. Hil.). Author(s): GAIAD, S.; RAKOCEVIC, M.; REISSMANN, C. B. Repository: BDPA Publication year: 2006
Photosynthetic activity and grape yield of 'Alicante Bouschet' (Vitis vinifera L.) grapevines submitted to nitrogen supply methods and doses. Author(s): STEFANELLO, L. O.; SCHWALBERT, R.; MARQUES, A. C. R.; TAROUCO, C. P.; VITTO, B. B.; KRUG, A. V.; SANTOS, J. P. J. dos; GALARZA, B. P.; ZALAMENA, J.; SANTOS, H. P. dos; MELO, G. W. B. de; BRUNETTO, G. The great majority of sandy soils present low nitrogen availability, generally below vines physiological demand, and therefore nitrogen fertilizer application, such as urea, is necessary. However, whe... ... Repository: BDPA Publication year: 2020
High copper content in vineyard soils promotes modifications in photosynthetic parameters and morphological changes in the root system of "Red Niagara" plantlets. Author(s): AMBROSINI, V. G.; ROSA, D. J.; MELO, G. W. B. de; ZALAMENA, J.; CELLA, C.; SIMÃO, D. G.; SILVA, L. S. da; SANTOS, H. P. dos; TOSELLI, M.; TIECHER, T. L.; BRUNETTO, G. High copper (Cu) soil contents, due to the continuous vineyard application of Cu fungicides throughout the years, may impair the growth of the shoot and modify the structure of the root system. The cu... ... Repository: BDPA Publication year: 2018
Gas exchange rates, plant height, yield components, and productivity of upland rice as affected by plant regulators. Author(s): ALVAREZ, R. de C. F.; CRUSCIOL, C. A. C.; NASCENTE, A. S.; RODRIGUES, J. D.; HABERMANN, G. The objective of this work was to evaluate gas exchange rates, plant height, yield components, and productivity of upland rice, as affected by type and application time of plant growth regulators. A r... ... Repository: BDPA Publication year: 2012
Large-scale water productivity assessments with MODIS images in a changing semi-arid environment: a Brazilian case study. Author(s): TEIXEIRA, A. H. de C.; SCHERER-WARREN, M.; HERNANDEZ, F. B. T.; ANDRADE, R. G.; LEIVAS, J. F. In the Brazilian semi-arid region, the intensification of agriculture results in a change of natural vegetation by irrigated crops. To quantify the contrast between these two ecosystems, the large-sca... ... Repository: BDPA Publication year: 2013
Silvopastoral system with Eucalyptus as a strategy for mitigating the effects of climate change on Brazilian pasturelands. Author(s): BOSI, C.; PEZZOPANE, J. R. M.; SENTELHAS, P. C. The aim of the present study was to assess the effect of Eucalyptus trees in a silvopastoral system on the microclimate and the capacity of that to mitigate the effects of climate change on pasturelan... ...

Energy partitioning and methane emission by sheep fed sorghum silages at different maturation stages. Author(s): MACHADO, F. S.; RODRÍGUEZ, N. M.; GONÇALVES, L. C.; RODRIGUES, J. A. S.; RIBAS, M. N.; PÔSSAS, F. P.; JAYME, D. G.; PEREIRA, L. G. R.; CHAVES, A. V.; TOMICH, T. R. ABSTRACT - Energy partitioning and methane production by sheep fed silages of three commercially available sorghum hybrids (BRS 610, BR 700 and BRS 655) harvested at three maturation stages (milk, sof... ... Repository: BDPA Publication year: 2015
Reflectância de macieiras a pleno sol e sob dois tipos de antigranizo: considerações para o sensoriamento remoto proximal. Author(s): RUFATO, A. de R.; AMARAL, L. DE P.; GEBLER, L. O risco de chuvas de granizo levou à adoção massiva de cobertura dos pomares de macieira com tela antigranizo, criando um novo microclima em termos de radiação solar e temperatura do ar. Na agricultur... ... Repository: BDPA Publication year: 2024
Monitoring anomalies on large?scale energy and water balance components by coupling remote sensing parameters and gridded weather data. Author(s): TEIXEIRA, A. H. DE C.; LEIVAS, J. F.; TAKEMURA, C. M.; GARCON, E. A. M.; SOUSA, I. F. DE; AZEVEDO, A. Abstract The SAFER (Simple Algorithm for Evapotranspiration Retrieving) algorithm was applied with MODIS images and gridded weather data from 2007 to 2021, to monitor the energy balance components and... ... Repository: BDPA Publication year: 2024
Performance and uncertainty of the all-wave net radiation space-time integrators by treetops. Author(s): ANGELOCCI, L. R.; PILAU, F. G.; SIMON, J.; MARIN, F. R.
