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
Standardized sampling plan for Aphis gossypii based on the cotton cultivar, plant phenology and crop size. Author(s): ARAÚJO, T. A.; ARAUJO, L. H. A.; SILVA, N. R.; LUZ, C. E. A.; SILVA, E. M. da; MOREIRA, M. D.; SUINAGA, F. A.; PICANÇO, M. C.; BASTOS, C. S. A standardized sampling plan is the starting point for developing a decision‐making system for pest control. Aphis gossypii (Hemiptera: Aphididae) is a destructive sapfeeding pest on cotton worl... ... Repository: BDPA Publication year: 2019
Expression of NCED gene in colored cotton genotypes subjected to water stress. Author(s): SOUZA, A. M. S. de; BATISTA, V. G. L.; PINHEIRO, M. P. N.; SUASSUNA, J. F.; LIMA, L. M. de; FERNANDES, P. D.
