The Behavior Of Red Clover And Italian Ryegrass Mixture, Fertilized With Gulle And Manure

It is well known that red clover (Trifolium pratense L.) has a good agricultural value when is cultivated in wet and cold areas, with annual rainfall of 600 mm. Italian ryegrass (Lolium multiflorum Lam.) requires special climatic conditions, but is complementary with red clover. This mixture is often used by farmers due to the high productivity and quality of the feed. The objective of this study is to track the performance of mixture Trifolium pratense L. + Lolium multiflorum Lam. in both gulle and farmyard manure fertilization management, according to the specific conditions of Subcarpathian Basin Cobatesti-Simonesti, Harghita, Romania. In the experiment were used four graduations of fertilization both with gulle (0 t gulle/ha, 5 t gulle/ha, 10 t gulle/ha and 20 t gulle/ha) and manure (0 t manure/ha, 10 t manure/ha, 30 t manure/haand 50 t manure/ha). Floristic composition was determined by gravimetric method and the results were interpreted by appropriate statistical methods. After two experimental years it was noticed that mixture's production suffered significantly influenced by both types of fertilizers. When larger quantities of fertilizer are applied, Italian ryegrass becomes very aggressive, being dominant in the mixture.
