Evaluation of cotton cultivars based on the compensatory increase of cotton squares after simulating damage by the cotton boll weevil. Author(s): ALVES, B. L. N.; SILVA, C. A. D. da; SERRÃO, J. E.; ZANUNCIO, J. C. The objective of this study was to evaluate cotton cultivars based on the compensatory increase of cotton squares in response to the simulation of the boll weevil damage. The first experiment aimed to... ... Repository: BDPA Publication year: 2021
Hemispherical photography to estimate biophysical variables of cotton. Author(s): BRANDAO, Z. N.; ZONTA, J. H. The Leaf Area Index (LAI) is a key parameter to evaluate the vegetation spectral response, estimating plant nutrition and water requirements. However, in large fields is difficult to obtain accurate d... ... Repository: BDPA Publication year: 2016
Diallel analysis for technological traits in upland cotton. Author(s): QUEIROZ, D. R.; FARIAS, F. J. C.; CAVALCANTI, J. J. V.; CARVALHO, L. P. de; NEDER, D. G.; SOUZA, L. S. S.; FARIAS, F. C.; TEODORO, P. E. Final cotton quality is of great importance, and it depends on intrinsic and extrinsic fiber characteristics. The objective of this study was to estimate general (GCA) and specific (SCA) combining abi... ... Repository: BDPA Publication year: 2017
Cotton response to water deficits at different growth stages. Author(s): ZONTA, J. H.; BRANDAO, Z. N.; RODRIGUES, J. I. da S.; SOFIATTI, V. Water deficit at certain cotton growth stages can cause severe damage to crop development, affecting physiological processes and reducing reproductive structures, with consequent yield losses. The obj... ... Repository: BDPA Publication year: 2017
Spectral reflectance for growth and yield assessment of irrigated cotton. Author(s): BRANDAO, Z. N.; SOFIATTI, V.; BEZERRA, J. R. C.; FERREIRA, G. B.; MEDEIROS, J. C. The canopy reflectance using ground-based sensors has the potential to provide information on crop nitrogen content. The objective of this study was to determine relationships between canopy spectral... ... Repository: BDPA Publication year: 2015
Compensation to pest injuries by replacing floral structures by cotton plants. Author(s): MIRANDA, J. E. Cotton crop have a relatively long cycle, with fruiting time starting from 45 days after emergence, and the abscission and spare floral structures is common and varies with the phenological stage. Thi... ... Repository: BDPA Publication year: 2016
Correlations and path analysis among agronomic and technological traits of upland cotton. Author(s): FARIAS, F. J. C.; CARVALHO, L. P. de; SILVA FILHO, J. L. da; TEODORO, P. E. To date, path analysis has been used with the aim of breeding different cultures. However, for cotton, there have been few studies using this analysis, and all of these have used fiber productivity as... ... Repository: BDPA Publication year: 2016
Biplot analysis of phenotypic stability in upland cotton genotypes in Mato Grosso. Author(s): FARIAS, F. J. C.; CARVALHO, L. P. de; SILVA FILHO, J. L. da; TEODORO, P. E. Seed cotton yield is a trait governed by multiple genes that cause changes in the performance of genotypes depending on the cultivation environment. Breeding programs examine the genotype x environmen... ... Repository: BDPA Publication year: 2016
Behavioral aspects of Helicoverpa armigera in the cotton vegetative phase. Author(s): RODRIGUES, S. M. M.; SANTOS, N. do C.; PITTA, R. M.; CORASSA, J. de N. US-EN: Helicoverpa armigera (Hübner) is part of an important complex of insects-pests that attack the cotton crop. This study aimed to identify the preferential plant parts for the oviposition of moth... ... Repository: BDPA Publication year: 2019
Diallel analysis for agronomic traits in upland cotton in semi-arid zones in Brazil. Author(s): QUEIROZ, R. R.; FARIAS, F. J. C.; CARVALHO, L. P. de; NEDER, D. G.; SOUZA, L. S. S.; FARIAS, F. C.; TEODORO, P. E. This study aimed to estimate the general- (GCA) and specific-combining ability (SCA) and obtain information on the genetic control of agronomic traits among six upland cotton genotypes and their hybri... ...
