PRODUCTIVITY OF BLUE LUPINE ON SOD-PODZOLIC LOAMY SAND SOIL

Abstract

Cultivation of blue lupine on sod-podzolic loamy sand soil, medium supplied by mobile forms of phosphorus and potassium has ensured in the average 33,1 ts/hectares of grain. Influence of fertilizers on productivity of grain was uncertain. Average specific removal with 1 т of grain and corresponding quantity of straw was: N - 59,7 kg/t; Р2О5 - 16,8; К2О - 29,9; СаО - 8,6; MgO - 6,4 kg/t. For self-supporting of balance of mobile forms of phosphorus and potassium in soil at cultivation of blue lupine for grain production it is necessary to apply 50-60 P2O5 kg/hectares of phosphoric fertilizers and 100-110 K2O kg/hectares of potassium fertilizers; under a condition of lupine straw tillage the demanded rate of phosphorus is 40 kg/hectares, potassium - 20 kg/hectares.
