Study on the Effect of Primary Tillage Practices, Planting Machines and Different Seed Densities on the Yield of Rain-Fed Wheat

Hossein Ali Shamsabadi

Abstract:
To study the effects of four types of primary tillage implements separately and seed densities on the yield of rain fed wheat using deep drill planting with press wheel and drill planting with end wheels, an experiment was conducted in research farm of Gonbad Agricultural faculty during 3 years (1997-2000), split block factorial design with three replications was used as experimental design. The primary tillage implements included: Moldboard Plow (MP), Disc Plow (DP), Chisel Plow (CP) and Offset Disc (OD). TAJEN wheat cultivar was planted at the rates of 140, 150 and 160 kg ha-1. Crop yields for different treatments were measured at the end of the study. The results showed that grain yield was not affected by seed density and types of tillage machines. But year, replicationxyear, planting machine and interaction effect of yearxplanting machine had significant effects on the grain yield (p<1%). As a result, considering the priority of soil physical properties, reduced tillage could be recommended as a promising strategy to improve soil physical quality, preventing soil erosion and to ensure moisture control, less energy consumption and fast preparation of soil as well as reducing costs of production, using of Chisel Plow with 140 or 150 kg ha-1 seed density with deep drill planting machine is suggested to increase wheat yield.
