Mapping of summer agricultural crops in the Alto Paraguai basin through EVI/MODIS time series. Author(s): CECHIM JÚNIOR, C.; ANTUNES, J. F. G.; JOHANN, J. A.; ESQUERDO, J. C. D. M. The main land use and land cover (LULC) changes that a given area passes over the time can be evaluated by using spatial-temporal analysis of satellites images. Then, it is possible to identify the LU... ... Repository: BDPA Publication year: 2017
Zonal application of plant growth regulator in cotton to reduce variability and increase yield in a highly variable field. Author(s): VAZ, C. M. P.; FRANCHINI, J. C.; SPERANZA, E. A.; INAMASU, R. Y.; JORGE, L. A. de C.; RABELLO, L. M.; LOPES, I. de O. N.; CHAGAS, S. das; SOUZA, J. L. R. de; SOUZA, M. de; PIRES, A.; SCHEPERS, J. Variable-rate application has great potential to reduce variability and increase yield by spatially optimizing agricultural inputs. In cotton, plant growth regulators (PGRs) control excessive growth a... ... Repository: BDPA Publication year: 2023
