Abstract

This study was carried out in the form of a split-plot complete randomized block design with 16 treatment combinations and in 4 replications for three crop years 2018-2020 in the Gachsaran agricultural research. The experimental factors include tillage method (A) with two levels A1=conventional (moldboard plow + disk harrow) and A2= conservation (No-Till) which were placed in the main plots and rotation (B) with eight levels consisting of 1) wheat - wheat (control), 2) barley-barley (control), 3) Forage (Tolo variety) - wheat, 4) Forage - barley, 5) canola - wheat, 6) canola - barley, 7) chickpea - wheat and 8) Chickpea-Barley were placed in sub-plots. The results showed that the increase in yield in wheat rotation was 19.3, 18.2 and 20.7%, respectively, The highest amount of plant biomass in wheat treatments was obtained by 9352 kg ha-1 from the forage rotation option . The conventional cultivation method in the canola rotation option increased the amount of moisture in the soil and reduced the specific gravity of the soil. There was the lowest amount of phosphorus and the highest amount of potassium and soil organic carbon percentage in this periodic option. Due to the higher productivity, to alternate wheat and barley crops with canola in conservation tillage conditions, and at the same time, chickpea and forage crops should be used in the middle of their rotation period. Therefore, the acceptance of this system by farmers requires the implementation of this study in the conditions of rainfed agriculture,
