Abstract

Red clover ranks second only to alfalfa in terms of prevalence and significance in the production of bulky livestock fodder. Although alfalfa is considered more productive and of higher quality, large areas of land in Bosnia and Herzegovina are unsuitable for alfalfa cultivation (heavy, acidic soils). As a result, clover generally occupies larger areas than alfalfa. This crop thrives well in cool, moist, moderately heavy to heavy soils with slightly acidic to neutral reactions. Given that the quality of biomass and productivity of red clover largely depend on soil fertility, variety, environmental conditions and growth stage at harvest, this study aimed to determine the effect of fertilization (N0, N20, N40 and N60) of red clover cultivars (Global and Una), in the agro-ecological conditions of Butmir, on the yield of dry matter, crude protein and the abundance and activity of nodule bacteria. The research results indicated that both the cultivar and the application of nitrogen fertilizer had a significant impact on the productivity and quality properties of red clover (dry matter yield, crude protein yield). The highest annual dry matter yield was achieved with the N60 variant for the Global cultivar (8.48 t/ha) and the N40 variant for the Una cultivar (8.50 t/ha). Similarly, the highest protein yield was recorded with the N60 variant for the Global cultivar (1,262.1 kg/ha) and with the N40 variant for the Una cultivar (1,073.9 kg/ha).
