The hybrid genotypes of genotypes of corn H3 and H5 were superior than cultivars Tuxpeño and Centapasaquina . Grain yield was 4 t / ha for the control , which surpassed significantly ( P < 0.05 ) the production obtained for corn grain ...

Panicum maximum P. maximum is one of the highest quality grasses and the main deficiency of current cultivars is lack of ... tolerance among the hybrid P. maximum populations were the same as for the Centrosema and Leucaena programs .

The species M. artemisiana and the Leucaena hybrid reached lower height than the other three species . ... differ significantly , but were higher ( P < 0.05 ) in combination " a " than in combination " b " in all periods of evaluation .

These hybrids were interesting inasmuch as they grew much more rapidly in their youth than pure L. pulverulenta seedlings . ... another advantage over Leucaena glauca by their far higher production of firewood ( see Schweizer 1940 , p .
