Dietary zinc (Zn) deficiency is widespread globally, and is particularly prevalent in low- and middle-income countries (LMICs). Cowpea (Vigna unguiculata (L.) Walp) is consumed widely in LMICs due to its high protein content, and has potential for use in agronomic biofortification strategies using Zn. This study aimed to evaluate the effect of Zn biofortification on grain nutritional quality of 29 cowpea genotypes. Zn application did not increase cowpea yield. In 11 genotypes sucrose concentration, in 12 genotypes total sugar concentration, and in 27 genotypes storage protein concentration increased in response to Zn supply. Fifteen genotypes had lower concentrations of amino acids under Zn application, which are likely to have been converted into storage proteins, mostly comprised of albumin. Phytic acid (PA) concentration and PA/Zn molar ratio were decreased under Zn application. Six genotypes increased shoot ureides concentration in response to Zn fertilization, indicating potential improvements to biological nitrogen fixation. This study provides valuable information on the potential for Zn application to increase cowpea grain nutritional quality by increasing Zn and soluble storage protein and decreasing PA concentration. These results might be useful for future breeding programs aiming to increase cowpea grain Zn concentrations through biofortification. |

Brazil is the first world producer of sugar cane. Despite the economic and social importance of agribusiness to Brazil, it is still difficult to estimate the harvest of the its main agricultural crops with the precision and anticipation needed, justifying the study and development of new methods based on the use of remote sensing data, for example. Even considering the increasing availability of high spatial resolution images in recent years, AVHRR/NOAA satellites have some characteristics suitable for application in operational methods of agricultural monitoring specially for a crop like sugar cane. Thus, this paper had the main objective to identify sugar cane areas in the state of Sao Paulo using harmonic analysis applied to a time series of AVHRR/NOAA-17 available at CEPAGRI/UNICAMP. A decision tree was calculated to search patterns that could represent the sugar cane along the crop season 2006/2007. Application of these two methods (harmonic analysis and decision tree) on the time series used was able to identify sugar cane areas in the state of Sao Paulo (Brazil) with 92% confidence when compared to ground truth based on LANDSAT/TM images and available at CANASAT?s webpage (http://www.dsr.inpe.br/canasat). This methodology can be applied in an operational way to support the official systems of harvest forecasting. |
