The forage biomass productions in the continuous cultivation system of the agricultural land. II. Forage structures based on the silage corn culture
Keywords:
continuous cultivation, forage system, silage corn, cumulated productionsAbstract
The forage system proposed by the continuous land cultivation has taken under research 5 structures of forage plants, grown one after the other over a period of 2 agricultural years (2009/2010, 2010/2011). In every type of structure the silage corn culture was introduced. Each structure has been studied both under conditions of non fertilization with nitrogen (N0) and with fertilization (N+). As compared to the cultivation structure of the silage corn in monoculture, for 2 years, in other structures, in which were introduced legumes sowed in association, the cumulated quantities of forage biomass have been 30-50% bigger, and the soil has been covered with vegetation in a proportion of over 80% during the entire period of the forage system.
