Geostatistical analysis of crop yield maps in a long term no tillage system. Author(s): GUEDES FILHO, O.; VIEIRA, S. R.; CHIBA, M. K.; GREGO, C. R. It is known, for a long time, that crop yields are not uniform at the field. In some places, it is possible to distinguish sites with both low and high yields even within the same area. This work aime... ... Repository: BDPA Publication year: 2010
Spatial Relationships Between Soil Water Content and Hydraulic Conductivity in a Highly Structured Clay Soils. Author(s): VIEIRA, S. R.; GREGO, C. R.; TOPP, G. C.; REYNOLDS, W. D. The water, element essential for life, is present as a large reservoir in the soil. Soil water content varies in space as a consequence of the variability of other related properties and its study is... ... Repository: BDPA Publication year: 2014
Jack knifing for semivariogram validation. Author(s): VIEIRA, S. R.; CARVALHO, J. R. P. de; PAZ GONZÁLEZ, A. The semivariogram function fitting is the most important aspect of geostatistics and because of this the model chosen must be validated. Jack knifing may be one the most efficient ways for this valida... ... Repository: BDPA Publication year: 2010
Crossbreeding applied to systems of beef cattle production to improve performance traits and carcass quality. Author(s): FAVERO, R.; MENEZES, G. R. de O.; TORRES JUNIOR, R. A. de A.; SILVA, L. O. C. da; BONIN, M. N.; FEIJO, G. L. D.; ALTRAK, G.; NIWA, M. V. G.; KAZAMA, R.; MIZUBUTI, I. Y.; GOMES, R. da C. Crossbreeding represents an important technique to improve growth, beef quality and adaptability in beef production systems in tropical countries. The aim of this study was to evaluate sire and dam br... ... Repository: BDPA Publication year: 2019
Variability and spatial correlation of aggregates and organic carbon in Indian Dark Earth in Apuí region, AM. Author(s): GOMES, R. P.; CAMPOS, M. C. C.; BRITO, W. B. M.; CUNHA, J. M. da; MUNIZ, A. W.; SILVA, L. S.; SOUZA, E. D. de; OLIVEIRA, I. A.; FREITAS, L. de Variabilidade e correlação espacial de agregados e carbono orgânico em Terra Preta de Índio na região do Apuí, AM. The study of variability associated to the soil attributes spatial correlation, as OC... ... Repository: BDPA Publication year: 2018
Chlorogenic acid concentration in Brazilian carrots cultivars. Author(s): MALDONADE, I. R.; CARVALHO, A. D. F. de; COELHO, L. F. S.; RIBEIRO, R. L. V. Repository: BDPA Publication year: 2015
Oocyte quality in post-partum of 3/4 and 7/8 Holstein x Zebu primiparous crossbred cows. Author(s): CARVALHO, B. C. de; BRANDÃO, F. Z.; SANTOS, G. B.; VARAGO, F. C.; OTTO, P. I.; VARGAS, M. W.; GRÁZIA, J. G. V.; CAMARGO, L. S. de A. Repository: BDPA Publication year: 2013
Análise espacial da precipitação pluviométrica no Estado de São Paulo: comparação de métodos de interpolação. Author(s): CARVALHO, J. R. P. de; ASSAD, E. D. O objetivo deste trabalho é comparar três interpoladores univariados: inverso do quadrado da distância, curvatura mínima e krigagem ordinária usando observações de precipitação pluvial média anual de... ...

Detrending non stationary data for geostatistical applications. Author(s): VIEIRA, S. R.; CARVALHO, J. R. P. de; CEDDIA, M. C.; PAZ GONZÁLEZ The use of geostatistics requires at least that the intrinsic hypothesis be satisfied. The presence of a trend in the data invalidates this hypothesis. One of the ways of solving this problem is by su... ... Repository: BDPA Publication year: 2010
Hyperthermotherapy in the Rice Emasculation Process. Author(s): AGUIAR, G. A.; STRECK, E. A.; FACCHINELLO, P. H. K.; GOULART, C.; MAGALHAES JUNIOR, A. M. de; MAIA, L. C. da Repository: BDPA Publication year: 2017
