Grain yield, anthesis-silking interval and drought tolerance indices of tropical maize hybrids. Author(s): SANTOS, A. de O.; VON PINHO, R. G.; SOUZA, V. F. de; GUIMARAES, L. J. M.; BALESTRE, M.; PIRES, L. P. M.; SILVA, C. P. da Water deficit stress is the abiotic factor with the highest impact on crop yield. The objective of this study was to evaluate grain yield (GY), the anthesis-silking interval (ASI) and drought toleranc... ... Repository: BDPA Publication year: 2020
The Evaporative Stress Index as an indicator of agricultural drought in Brazil: An assessment based on crop yield impacts. Author(s): ANDERSON, M. C.; ZOLIN, C. A.; SENTELHAS, P. C.; HAIN, C. R.; SEMMENS, K.; YILMAZ, M. T.; FENG GAO; OTKIN, J. A.; TETRAULT, R.

Microbial indicators of soil quality and soybean yield in agricultural production system using cover crops under no-tillage. Author(s): SOUSA, D. C. de; ROSA, J. D.; MEDEIROS, J. C.; BOECHAT, C. L.; NÓBREGA, R. S. A.; SOUZA, H. A. de; SAGRILO, E. Cover crops improve the physical, chemical and biological quality of the soil and boost crop yield. However, the magnitude of the effects on the microbial activity in tropical soils of Cerrado is stil... ... Repository: BDPA Publication year: 2023
Yield and morphophysiological indices of irrigated rice genotypes in contrasting ecosystems. Author(s): SANTOS, M. P. dos; ZANON, A. J.; CUADRA, S. V.; STEINMETZ, S.; CASTRO, J. R. de; HEINEMANN, A. B. Rice phenology and development are events controlled by environmental and genetic factors, and the yield potential of the crop is defined by their interaction. This study aimed at analyzing the perfor... ... Repository: BDPA Publication year: 2017
Relative yield of wheat in coexistence with concurrent plants as indicator of competitiveness. Author(s): REINEHR, M.; LAMEGO, F. P.; CARATTI, F. C.; PERUZZO, S. T.; FABIANI, M. F.; MAZZON, M. One of the factors that limit the yield of wheat is the weed competition, being the competitive potential of plants affected by their morphophysiological characteristics. The objective of this study w... ... Repository: BDPA Publication year: 2018
