this study was conducted to investigate the effect of soil moisture content in primary tillage and travel speed during disking operation on the performance of an offset disk harrow in a silty clay loam soil. at first, the effect of three soil moisture content ranges of (12-14), (14-16) and (16-18) percent (dry basis) on soil clod size (left from moldboard plowing) was investigated. then, the pe...
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
The discrepancy between the plow width and tractor leads to asymmetry of plowing units. geometry plowshare surface moldboard contributes generation lateral forces on working tool. All this imbalance tool deviation from straight-line movement during plowing. To maintain movement, driver has adjust machine every 5-10 meters, which is highly tiresome. study causes slips unit, we constructed a math...

some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
The analysis of soil cultivation technologies for sowing melon crops was carried out. design a combined tillage tool capable plowing, pre-sowing treatment and formation irrigation furrows in one pass substantiated. main is recommended to be done by front plow tools smooth plowing. Plow bodies two bottom plows should mounted along the symmetry axis implement according lister scheme, which allows...
At present, the role of agricultural practices on dynamic GHGs is being investigated worldwide. In this study, effects soil tillage (conventional vs. conservation techniques) and fertilization sources (inorganic organic) CO2 emissions in durum wheat (Triticum Desf.)–potato (Solanum tuberosum L.) rotation Mediterranean area were evaluated. This study aimed to understand changes carbon content un...
