Sažetak
An annual investigation of energy consumption and machinery work with three various soil tillage practices at soybean production, vriety Tisa, was conducted in east Croatia. Conventional, conservation and no till were tillage practices applied. Energy comparison indicates a markedly energy consumption at the conventional soil tillage (ploughing, disking and seeding)with 56, 86 kg/ha or 18, 85 kg/t of the diesel (D-2) fuel. More convinient variant is conservation soil tillage (shovel loosening, disking seeding)demanding 45, 51 kg/ha or 16, 88 kg/t being 20 % i.e. 10, 5 % less compared to the conventional practice. The most favourable variant, in terms of energy, is no till with only 5, 71 kg/ha or 1, 86 kg/t of diesel D-2, being 90 % less compared to the conventional practice. Comparison of the investigated variants productivity indicates that conventional practice requires 1, 97 h/ha or 0, 65 h/t, conservation 1, 40 h/ha or 0, 52 h/t being 29 % i.3. 20 % whereas no till demands only 0, 29 h/ha or 0, 09 h/t being 85, 3 % i.e. 86, 2 % less compared to the conventional one. Direct soybean seeding resulted in reducing production costs of 130, 74 euro/ha, primarily due to reduction of soil tillage and chemical protection. The lowest yield of 2, 70 t/ha was accomplished with a conservation tillage and the highest one of 3.07 t/ha by no till application.
