Evaluation of the Effect of Reduced and Conventional Tillage Methods on Machine Performance Parameters, Soil Properties and Quantitative and Qualitative Efficiency of Sugarcane

This research was carried out in Hakim Farabi Agro-Industry Company located in 35 km of Ahvaz-Abadan road in the years 2016 to 2018 by the method of random complete blocks design and was performed in three replications. The comparative treatments included 1- using the subsoil twice D8 bulldozer (conventional operation), 2- Alpego composite tillage, 3- Nardi composite tillage and 4- subsoil using D8 bulldozer + Khorasan forging tractor subsoil.  The results of this study showed that there was no significant difference between different treatments in terms of yield components (quantitative and qualitative indices of sugarcane). Also, different treatments had a significant effect on soil physical properties and performance parameters. In stem height, yield, syrup brix and purity, the highest values related to the second treatment, with 236 cm, 102 t ha-1, 19.95% and 93.85%, respectively, and in the weight average of the diameter of the lumps, specific mass apparent, at depths of 30 to 60, soil resistance at depths of 0-30 cm, fuel consumption and operating time, the lowest values, respectively, related to the third treatment with 38.33 mm, the second treatment with 1.15 g (cm3)-1 The second treatment was 104.96 pascal, the second treatment was 48.33 liters per hectare, and the second treatment was 2.21 hours.
