A split root and pod solution culture technique was used to examine the effects of Ca concentration on fruiting of one Virginia cv. 'Virginia Bunch 1' and one Spanish peanut cv. 'TMV-2'. Plants were grown in comp ...

Peanut production in drought prone areas should be enhanced by the development of cultivars that can fix more nitrogen (N) under drought conditions. The aims of this study were to estimate heritability for NF and to estimate phenotypic and genotypic correlations among traits related to ...

A major limitation of the application of a crop simulation model is the determination of cultivar coefficients, as the recommended procedure requires extensive data sampling throughout the growing season which is very impractical when a large number of lines are involved or when critical resources are limited. Our previous study has shown that a reduced set of experimental data can be used to accu ...
