field stationary experiment was carried out during 2001– 2005 at the Experimental base of the SPU in Dolná Malanta. The long-term average annual temper­ature of the site is 9.7°C and 16.6°C during the vegetation period. The average rainfall is 561 mm, including 323 mm during the vegetation period. The aim of the study was to evaluate yield and the energy balance of common pea growing under different soil tillage and fertilization treatments. The tillage treatments were as follows: conventional tillage (to the depth of 0.25 m), reduced tillage (to the depth of 0.18 m), and minimized tillage (to the depth of 0.10 m). (EZ), additional energy input (VE), and energy of yield (EHÚ). Rational utilization of energy input (VR) and additional energy input (VE) were also significantly influenced by evaluated fertilization treatments. The lowest yield of common pea was reached by minimized technology of soil cultivation. The highest energy gain was reached by the tillage to the depth 0.18 m and the lowest by the minimized tillage.
