Genetic parameters for test day milk yields of first lactation Holstein cows by random regression models. Author(s): MELO, C. M. R. de; PACKER, I. U.; COSTA, C. N.; MACHADO, P. F. Covariance components for test day milk yield using 263 390 first lactation records of 32 448 Holstein cows were estimated using random regression animal models by restricted maximum likelihood. Three... ... Repository: BDPA Publication year: 2007
Computational models in precision fruit growing: reviewing the impact of temporal variability on perennial crop yield assessment. Author(s): MAGRO, R. B.; ALVES, S. A. M.; GEBLER, L. Early yield information of perennial crops is crucial for growers and the industry as it enables cost reduction and facilitates rop planning. However, assessing the yield of perennial crops using comp... ... Repository: BDPA Publication year: 2023
Peak yield and peak time in Girolando cattle using nonlinear models. Author(s): DALTRO, D. S.; MACHADO, J. D.; HAIDUCK, A. P.; KERN, E. L.; SILVA, M. V. G. B.; PANETTO, J. C. do C.; NETO, J. B.; COBUCI, J. A. Repository: BDPA Publication year: 2017
Sediment yield modeling using an alternative environmental scenario in northwestern Rio de Janeiro - Brazil. Author(s): MARCHIORO, E.; FERNANDES, N.; MACEDO, J.; BHERING, S.; GONCALVES, A.; PRADO, R. The northwestern Rio de Janeiro (RJ-Brazil) area has been going through deep transformations in its soil use and occupation, which has contributed to increased sediment yield and changes in the soil-w... ...

Implications of water management on methane emissions and grain yield in paddy rice: a case study under subtropical conditions in Brazil using the CSM-CERES-Rice model. Author(s): SILVA, E. H. F. M. da; HOOGENBOOM, G.; BOOTE, K. J.; CUADRA, S. V.; PORTER, C. H.; SCIVITTARO, W. B.; STEINMETZ, S.; CERRI, C. E. P. Rice (Oryza sativa L.) is a staple food and plays a crucial role in the food security of many countries. However, rice cultivation is associated with significant methane (CH4) emissions, contributing... ... Repository: BDPA Publication year: 2025
Sensitivity of the sorghum yield to individual changes in climate parameters: modelling based approach. Author(s): GROSSI, M. C.; JUSTINO, F.; RODRIGUES, R. de A.; ANDRADE, C. L. T. Based on sensitivity analyses the effect of changing in climate on sorghum has been investigated. This has been achieved by conducting crop modeling experiments carried out with weather observations a... ... Repository: BDPA Publication year: 2015
Early prediction models for cassava root yield in different water regimes. Author(s): VITOR, A. B.; DINIZ, R. P.; MORGANTE, C. V.; ANTONIO, R. P.; OLIVEIRA, E. J. de The development of cassava (Manihot esculenta Crantz) varieties with greater tolerance of water deficit depends on optimized phenotyping tools. The objective of this work was to develop early predicti... ... Repository: BDPA Publication year: 2019
