Abstract

Background and Aim: The lack of Organic matter in various kinds of soil in Iran caused unstable Soil structure, crop decreases, and land degradation. One of the methods of improving soil quality is the application of a cheap organic conditioner such as sawdust. Sawdust represents a soil conditioner that can change the physical and chemical properties of soil. Sawdust can be one of the options to improve the physical properties and quality of soil due to its low electrical conductivity, low heavy metal content, ability to create pores and better aeration, and high water holding capacity. Therefore, the aim of this research is to investigate the effect of sawdust and nitrogen on soil quality indices in bean cultivation. Method: This experiment was conducted in the form split-plot with RCBD with three replications. Sawdust was considered in four levels 0, 5, 10 and 15 ton/ha as the main factor and nitrogen fertilizer in three levels 75, 150, and 225 kg/ha. Sawdust and half of nitrogen fertilizer with preparing of plots were used and residual of nitrogen fertilizer applied in full established and flowering stage. According to oil testing, potassium and phosphorus fertilizers are not used. In this experiment, the number of bush, grain Yield, harvest index, and protein were measured. After crop harvesting, the physicochemical properties of soil such as OC, SP, FC, PWP, pb, and MWDwet were measured. Results: The results showed the use of sawdust and nitrogen fertilizer had a meaningful effect on the traits in bean and soil characteristics, with the increase of two factors, all traits increased. In the use of nitrogen, the maximum grain Yield was 1302 kg/ha which was obtained of 225 kg/ha of urea application compared with the level of 150 and 75 kg/ha, 9 and 44% increased respectively. In the use of sawdust, the maximum Yield of grain was 1269. 2 kg//ha obtained the use of 15 ton/ha of sawdust in comparing with no use of sawdust increased 21. 2%. In traits of Soil properties, sawdust in all traits and nitrogen fertilizer on OC, pb, and MWDwet are meaningful effects. Conclusion: sawdust as an organic material improved the quality of the soil. Thus, the use of these treatments increased soil porosity, organic carbon, and water-holding capacity in FC and PWP points. Therefore, sawdust can as a suitable organic fertilizer for improving the Organic matter of soil and the unsuitable condition of the soil.
