Sažetak
Four different soil tillage systems were tested in pumpkin seed production. Pumpkin variety was Gleissdorf, Austrian origin. The tested systems were: 1. Conventional (plough, disc harrow, combined seed-bed implement), 2. Conservation (plough, rotary harrow), 3. No-till (no-till planter), 4. Reduced (plough, combined seed-bed implement). The greatest yield of fresh pumpkin seeds of 1345 kg/ha was achieved by the conventional system. The reduced system achieved 1316 kg/ha, conservation system 927 kg/ha and no-till system achieved only 848 kg/ha. The greatest energy requirement of 1998 MJ/ha had the reduced system. The conventional system required 1919 MJ/ha, while conservation system required 1550 MJ/ha. The lowest energy requirement of 453 MJ/ha was achieved by no-till system.
