【 摘 要 】

Abstract. This paper tries to illustrate how intercropping increases the overall output of a cropping system and achieving much larger yields than sole crops by using environmental resources more fully over time or more efficiently in space. The research was conducted to establish the opportunity for optimal use of the growing area in perennial vegetables crops (Asparagus officinalis L., Rheum rhabarbarum L., Cynara cardunculus var. Scolymus, Levisticum officinale) by an intercropping system with annual vegetables (Brassica rapa subsp. Chinensis, Eruca sativa) in open field. The experiment was carried out in 2018 year in Vegetable Crops Research Institute (VCRI) Maritsa, Plovdiv, Bulgaria. Crops were grown under schemes: asparagus – 200+60/50 cm; artichoke – 200+60/90 cm; rhubarb – 200+60/90 cm; lovage – 200+60/50 cm; pak choi – 55+45+45+55/20 cm and 55+30+30+30+55/20 cm; rocket – 55+45+45+55/15 cm and 55+30+30+30+55/15 cm. As a result it was determined that the use of annual crops increases efficiency of the areas in perennial vegetables during the first year of growing. Annual vegetables pak choi and rocket grown under scheme 55 + 30 + 30 + 30 + 55/20cm and 55 + 30 + 30 + 30 + 55/15cm, respectively, are suitable for an intercropping system.
