The Influence of Sowing Time, Sowing Distance and Fertilization on Green Fodder Yield of Red Clover (Trifolium pratense L.)

In the area of Northeast Bosnia, the agro-technology of cultivation of the red clover is based on sowing in the spring (April), fertilization of NPK 15:15:15 and sowing manually according to the milk producer's survey on the cultivation of fodder crops and the applied agro-technology. Red clover could be classified in the second place after the quality of the fodder, behind the alfalfa. The goal of the research was to determine the extent to which the change in the red clover cultivation system (sowing time, intermediate sowing distance and the application of different quantities and combinations of NPK fertilizers) influences on the yield of red clover feed. The results of the research can provide a significant scientific and practical contribution to the improvement of the red clover cultivation in the agro-ecological conditions of northeastern Bosnia, as a very important component in ensuring quality of livestock feed. This research will provide an answer to the question of choosing agro-technics and fertilization systems in order to produce higher yields per unit area and better quality of red clover.
