The effect of subsoiling on the yield and physiological characteristics has been studied in sugar beet in the years 1986-1988. The trials have been established in the fields of the State Farm of Seed Production, Trnava, in arid maize growing region on medium heavy-textured loamy chernozem soils. The results indicated that a year was the strongest reason for variance during the whole experimental period. Subsoiling led to no significant differences neither in the yield, nor in the quality of sugar beet under the given soil and climatic conditions on an average for three years. A tendency to achieve higher qualitative factors. Leaf area exhibited higher values in the period of its most intensive growth (July). The influence of subsoiling was more considerable under the conditions of irrigation. Changes were recorded in nitrogen and potassium contents in the dry matter of leaf. The most significant effect of subsoiling was observed in the year with highest precipitation out of the growing season under the given soil and climatic conditions. Refined sugar yield amounted to 6.34 t per ha for the period of 1986-1988 under study, towards to the end of the growing season under the conditions of deep tillage, under the conditions of subsoiling this amounted to 6.36 t per ha. This amounted to 7.63 t per ha under the conditions of irrigation and deep tillage, under the conditions of subsoiling - 7.95 t per ha.
