Conventional tillage cause to break soil aggregates especially in loamy soils consequently increase soil sensitivity to water and winderosion. On the other hand, soil aggregate size distribution and aggregate stability are the two important physical properties of the soil with profound effects on soil health. Thus, soil sensitivity to destruction might be a criterion for evaluating soil agronomic capacity that may be defined by its stability i.e. physical structure. In an experiment carried out in 2011-12 crop season at agricultural education and research farm of Tehran University, Karaj. Iran (35048'N, 510'E, and 1321m above sea level) using randomized complete block design in split-plot arrangement with three replications physical soil parameters of aggregates size distribution and sta...

The experiment was conducted during 2013–15 at farm of the College of Agriculture and Natural Resources Faculty, Tehran University. The experiment was set up as a split plot, randomized complete block design with four replications. Three tillage methods (conventional tillage, minimum tillage and no-tillage) and three chickpea cultivars (ILC 482, Hashem and Arman) were allocated to the main and sub-plots, respectively. Land on the test site had 60% coverage of maize residue on the soil surface. Results from comparisons of averages showed that the no-tillage treatment had higher bulk density and lower soil porosity than the other tillage treatments. The highest evaluations for germination percentage, seed yield and harvest index were observed in chickpea cultivars in the conventional tillage treatment. Higher evaluations for chickpea seed yield in the first year were observed in cultivars ILC 482 (2594.9 kg/ha) and Hashem (2434.8 kg/ha) and in the second year in cultivar ILC 482 (2496.2 kg) under conventional tillage. Traits of germination percentage, seed yield and harvest index were higher in the second year of the experiment compared to the first year in minimum tillage and no-tillage treatments. This indicated a long-term positive effect of conservation tillage on plant growth and yield.
