This study was conducted to investigate the effect of different tillage methods, different levels of previous crop residues and different cultivars of soybean on yield and yield components of this plant. This experiment was conducted in the form of a factorial design with a completely randomized block base with three replications and during the growing season of 1399-1400 in one of the farms of Moghan Agriculture and Industry and Livestock Company located in the northeast of Ardabil province. In this study, two types of tillage systems (conventional and non-tillage) and two levels of wheat crop residues (complete and no residues) on the yield of two types of soybeans (Williams cultivar and L17 cultivar) were evaluated. The results of the effect of the mentioned systems on plant height, number of plants, 1000-seed weight, crop yield, percentage of protein and fat of soybean showed that the type of tillage had the most effect and the amount of residues had the least effect on the mentioned parameters. According to the results of the study of the effect of different tillage systems, the amount of residues and the type of plant planted on the agronomic characteristics of soybean at different levels can be expressed that by planting cultivar L17 cultivar soybean The highest crop yield can be achieved with conventional tillage method and complete amount of previous crop residues.

This study، in order to provide a suitable tillage method, more accurately estimate the water consumption of this crop per hectare, provide methods of water use efficiency with two types of ordinary water and magnetic. A split factorial experiment was conducted in a randomized complete block design with three replications in Jiroft city. The main treatment consisted of tillage method (Cyclotiller, Rotivator) and sub-treatments including two types of irrigation water (normal and magnetic) and two irrigation methods (Leakage, Linear drips) were selected. An innovative solar magnetic water device was used to irrigate the design. The effect of magnetic water on the type of irrigation showed very good and significant results at the level of 5%. The results showed that irrigation with magnetic water had a stimulating effect on the initial growth parameters of the plant, the coefficient of germination rate and germination percentage increased by 10 and 21%, respectively, compared to the control treatment. The highest 1000-seed weight with an average of 329.833 g was related to drip irrigation and the lowest value was related to leak irrigation treatment with an average of 327 g. Also, the use of cyclotiller and magnetic water in drip irrigation had a 22% increase in yield compared to the control treatment, so that the highest yield with 8800 kg/ha was related to tillage with cyclotiller and irrigation with magnetic water in drip irrigation system, Compared to other treatments.

In this experiment effect of wheat residuals management, Tillage and Nitrogen fertilizer on agronomic treat of soybean. This experimentwas done in three reptition in form of strip plot and in shap of statistical project of completely random blocks. Experimenting factors includes: Residuals as main factor, Tillage and Nitrogen fertilizer as secondary factors. Results from variance analysis on measured properties of soybean showed that residuals treatment had displayed meaningful difference in harvest index property. Harvest index was highest in the treatment of remains. Nitrogen fertilizer treatment had displayed meaningful difference in seed oil, seed yield and harvest index properties. Starter fertilizer treatment had the highest seed oil content, seed yield and harvest index. Also residuals management interaction and Tillage had displayed meaningful difference in seed yield property. The highest yield obtained in the treatment Residually with tillage, Residually without tillage, no-tillage remains. Also residuals management interaction and Nitrogen fertilizer had displayed meaningful difference in shell number in stem property. Most pods were obtained from the residue treated with starter fertilizer. Also Tillage interaction and Nitrogen fertilizer had displayed meaningful difference in seed oil, shell number in stem and seed yield properties. The highest percentage of oil obtained in the no-tillage treatments with starter fertilizer, tillage and starter fertilizer + NF, tillage and starter fertilizer and Most pods were obtained in treatments with tillage and starter fertilizer and The highest yield was obtained in treatments with tillage and starter fertilizer + NF, starter fertilizer with tillage, no-tillage and starter fertilizer.
