Comparison of Different Methods to Reduce Tillage Operation in Wheat Planting After Potato

Document Type : Research Paper

Abstract

In order to study the possibility of reduced tillage methods in Wheat planting after Potato, a field experiment was conducted on a sandy clay loam soil in the Tajarak Agricultural Research Station located in 70km Northeast of Hamedan. A randomized complete block design experiment with 8 tillage treatments (consisted of 1. Moldboard plowing + Twice disking + Leveler  2. Chisel plowing + Once disking + Leveler  3. Six bottoms plow + Once disking + Leveler  4. Once disking + Leveler  5. Sweeping + Leveler  6. Six bottoms plow + Leveler  7. Chisel plowing + Leveler  8. Leveler) was performed in 3 replication during 2 years (2001-2 and 2002-3). In this study, the machine parameters of forward speed, tractor drive wheel slip, working depth, field efficiency and theoretical and effective field capacity, as well as crop parameters of grain, straw yield and harvesting index, were measured or calculated.  It was noted the method of disking + leveler after potato harvesting was for wheat planting. However if sweep used after harvesting potato, only leveler can be suggested as the most suitable method.
