| description | Today cultivation of cereal in Sweden has high costs for establishment in relation to the rest of the world, and if this cultivation will be able to continue, the farmers have to control their costs. It is important to see all costs, not the maximum harvest achieved, but the net result. All farmers have different conditions with respect to soil, direction of the farm and were the farm is located geographically. With the right knowledge and ambitions, we think most farmers could change to reduced tillage.
In this paper we have tried to find out if reduced tillage is an alternative for farmers. We have done an experimental work of establishment with winter wheat on a fallow field with different machine concepts, from traditional tillage to reduced tillage. We have studied different concepts, not different manufacture. The experiment work was done in the southwest of Östergötland with some mould content middle clay soil.
The machines we have used are Väderstads Carrier, Direct Drilling, John Deere Mulch tiller, Kverneland Ecomat and Överum plow with and without ridge packer. The results in our experimental work show no significant differences in number of plants in the spring but big differences in establishment costs and some differences in occurrence of weed.
Our results show:
• The lowest soil preparation had Direct Drilling, 285 SEK/ha + the cost of sow drilling added.
• The highest soil preparation had Överum conventional, 1310 SEK/ha + the cost of sow drilling added.
• The lowest plant population had Överum conventional with 220 plants/m2.
• The highest plant population had Carrier with 244 plants/m2.
• The highest number of weeds had Direct Drilling.
• The lowest number of weeds had Överum conventional. |

Spannmålsodlingen i Sverige har idag i förhållande till omvärlden höga etableringskostnader och om denna odling ska kunna fortgå så måste lantbrukarna se över sina kostnader. Det är viktigt att se helheten med sina kostnader, inte högst skörd utan nettoresultatet. Alla lantbrukare har olika förutsättningar vad det gäller jordarter, inriktning på gården och var man befinner sig geografiskt. Med rätt kunskaper och vilja tror vi att de flesta kan övergå till reducerad jordbearbetning. Vi har i detta examensarbete försökt ta reda på om reducerad jordbearbetning är ett alternativ. För att få reda på detta har vi anlagt ett försök av etablering med höstvete på träda med olika maskinkoncept, allt ifrån traditionell bearbetning till grund bearbetning och direktsådd. Vi valde att undersöka olika maskinkoncept, inte olika fabrikat. Försöket utfördes i sydvästra Östergötland på en jordart som betecknas som något mullhaltig mellanlera. De maskinkoncept vi använde oss av var Direktsådd, Väderstads Carrier, John Deeres Mulch Tiller, Kverneland Ecomat samt Överum plog med och utan tiltpackare. Vad det gäller vårt undersökningsresultat så har vi inte kommit fram till några signifikanta skillnader i plantantal på våren, men stora skillnader i etableringskostnader och till viss del skillnad i ogräsförekomst. Våra kalkyler/beräkningsresultat visar att: • Lägst jordbearbetningskostnad hade Direktsådd, 285 kr/ha + såkostnad tillkommer. • Högst jordbearbetningskostnad hade Överum konventionellt, 1310 kr/ha + såkostnad tillkommer. • Lägst plantantal hade Överum konventionellt med 220 plantor/m2. • Högst plantantal hade Carrier med 244 plantor/m2. • Högst andel ogräs hade Direktsådd. • Lägst andel ogräs hade Överum konventionellt.
