Effect of different crop systems on fuel and energy consumption, and winter wheat yield

Due to the importance of the use of reduced tillage systems to reduce energy crops, an experiment was conducted as completely randomized block design with 6 treatment and 3 replications in 2011-2012 growing season in the khuzestan province. Treatments includeing conventional tillage using moldboard plow, conventional tillage without using moldboard plow, reduced tillage, no-tillage with 100% crop residue retained, no-tillage with 60% crop residue retained, no-tillage without crop residue retained. In this research, fuel consumption, time of any operation and total time of tillage and planting wheat, tillage and planting energy, emergence of wheat, weed density, the number of ears per square meter, operation of biological and wheat grain yield, harvest index, the weight of one thousand seeds, inpout energy, outpout energy, net energy, productivity energy, specific energy and effeciency energy are measured. The results show that the maximum and the minimum amounts of fuel were obtained in traditional culture treatment (93.67 L/ha) and in no-tillage treatment (14.57 L/ha), respectively. The maximum and minimum of efficiency energy is in reduced tillage (2.53%) and conventional tillage using moldboard plow (2.27%) treatments, respectively, and also the maximum and minimum of energy intensity is in conventional tillage using moldboard plow and reduced tillage treatments, respectively.Totally, the most expensive (12 million Rial/ha) and highest revenue generating (27.4 million Rial/ha) is obtained in conventional tillage using moldboard plow treatment than other treatments.Totally, the most expensive (12 million Rial/ha) and highest revenue generating (27.4 million Rial/ha) is obtained in conventional tillage using moldboard plow treatment than other treatments.Totally, the most expensive (12 million Rial/ha) and highest revenue generating (27.4 million Rial/ha) is obtained in conventional tillage using moldboard plow treatment than other treatments.Totally, the most expensive (12 million Rial/ha) and highest revenue generating (27.4 million Rial/ha) is obtained in conventional tillage using moldboard plow treatment than other treatments.Totally, the most expensive (12 million Rial/ha) and highest revenue generating (27.4 million Rial/ha) is obtained in conventional tillage using moldboard plow treatment than other treatments.
