In the conditions of the Republic of Belarus in course of the research there was studied the influence of various doses of phosphoric and potash fertilizers on productivity and fodder value of meadow clover (Trifolium pratense L.) of Vitebchanin variety in case of its additional sowing under winter triticale (Triticosecale). The research was realized in course of a long-term stationary field experiment at an agricultural production co-operative 'Shchemyslitsa' (Minsk region) on sod-podzolic light loamy soil developed on thick loess loam. Agrochemical characteristics of arable horizon: pH KCl - 5.8-6.0, P2O5 content - 400-420, K2O - 300-320 mg/kg of soil, humus - 1.8-2.0%, agrochemical cultivation index -0.92. Meadow clover of the first year of using was cultivated in 3 fields during 2008-2010 in a grain-grass crop rotation with the following rotation: field pea (Pisum arvense L.) and oat (Avena sativa) mixture on green mass - winter triticale with undersowing of clover - the first year's clover meadow - spring wheat (Triticum aestivum) - spring rape (Brassica napus). As a result of realized research it was revealed that application of phosphoric and potash fertilizers (P60K120) in the autumn under preseeding cultivation against after effect 40 t/ha of manure under winter triticale and spring top dressing of clover P60K140 was the most effective fertilizer system of clover meadow, the ensured 11.53 t/ha of green mass with the content of crude fiber of 17.7% and its gathering of 0.259 t/ha.
