INFLUENCE OF COMTRAST AGRO CLIMATIC GROW CONDITIONS OVER GRAIN YIELD OF SOME LATE BULGARIAN FORAGE CORN HYBRIDS

摘要

Results from contrast agro climatic grow conditions - dry-up and thermal stress, and water excess- influence investigation over grain yield in late forage corn hybrids Kneja 613 and Kneja M 625 - ones of the basic Bulgarian late corn hybrids with goodgrain yield abilities were presented in this paper. It is established that the Kneja 613 and Kneja M 625 have' got very good grain yield productive abilities and they are suitable for grow in different agro climatic conditions in order with its specificspecialty. The late forage corn hybrid - Kneja M 625 manifest good stability for dry up and allow to be made good and stable grain yields in dry up and thermal stress grow conditions. The late forage hybrid corn - Kneja 613 manifest best itself height grain yield productive abilities in water excess agro climatic grow conditions.
