Agronomic efficiency of liming on the yielding capacity of pea (Pisum), chemical composition of crop samples (seeds and straw), and nutritive elements removal was studied in the conditions of sod-podzolic loamy soils (with pH 5,51-6.00) of the Republic of Belarus. Efficiency of application of potash and potassium fertilizers in pea cultivation on content of the nutritive elements at the main stages of pea development (early flowering; early bean growth; late flowering; bean ripeness) was studied. Doses of mineral fertilizers exercised the highest influence on the content and intake of the nutritive elements by pea in its developmental stages. Application of N16P60R150 + dolomite powder and N36P60K15O + dolomite powder made it possible to obtain the maximum pea seeds yield. Lime application as well promoted the intake of calcium and magnesium by pea crops. Liming with the dolomite powder made it possible to increase pea yielding capacity on 1,7 c/ha. Application of potash fertilizer promoted the obtaining of extra yield of 3,1 c/ha. The maximum yield of pea seeds (58,7c/ha) was obtained after application of N16P60R150 + dolomite powder. Dolomite powder liming promoted the increasing of nitrogen and phosphorus content in pea seeds. Liming with chalk and sapropel carbonate promoted the growth of phosphorus content in seed in the variant of N16P60K90 + chalk, as well as the lowering of phosphorus level in pea chaff. Sapropel carbonate liming did not promote the increasing of total removal of the nutritive elements. The increasing of potash fertilizer doses caused the increasing of nitrogen, phosphorus and potash removal. In the variant with chalk application (76,6 kg/ha) there was stated the maximum calcium removal. Research results showed that liming exercised less influence on the chemical content of plants
