Productivity of red clover (Trifolium pratense L.) on acidic soil

Red clover is an important forage plant species for the production of fodder, primarily in mountain areas and soils of poorer quality. Low pH reaction of the soil and poor supply of phosphorus are limiting factors for the cultivation of most plant species on soils with such chemical characteristics. The aim of these investigations was to determine the productivity and variation in the height of the plant, the yield of green mass and the yield of hay of red clover grown on acidic soil, in order to find out which varieties give the highest yields of green mass and hay, and for the purpose of their greater use in production. The research was carried out by analyzing five varieties of red clover in two cuts in each of the two years in the BDS area of the city of Banja Luka. A large part of the soil of Republic of Srpska has an acidic reaction and also mostly has a low level of phosphorus. The selection of the best varieties of red clover for production on such soils will enable obtaining satisfactory forage yields. For the examined parameters, statistically significant differences were obtained between swaths and varieties. The highest average values of plant height, yield of green mass and hay were obtained in the first cutting of the second year. The lowest average yields were achieved by the variety Viola. The highest average height was of the variety Una, the highest yield of green mass was of the variety K-39, and the hay of variety Kolubara. Based on the obtained results, varieties K-39, Kolubara and Una can be recommended for growing on acidic soil.
