Effects of Irrigation on Yield and Composition of Principal Elements of Nutrients in Maize-Growing Soil
Extensive organic production under irrigation conditions requires greater amounts of NPK fertilisers. Furthermore, the mobility of fertilisers, especially of nitrogen, is greater under the increased soil moisture content, ... -
Factor Analysis of Milk Production on Selected Farms in Zlatibor District
This paper analyzes the main factors of milk production in dairy farms of Zlatibor region. Along with the analysis of breeds composition and genetic potential for milk production, proposal for improvements are presented. ... -
Results of the Investigation Effects of Soil Compaction on Yield of Winter Wheat
Moving of tractors and mobile systems can be divided in two groups: moving trough the inner parts of fields, and through the headlands. On headlands, soil compressing is more intensive due to lower moving speeds while ... -
Visual Parameters of Soybean (Glycine Max L.) as Influences by Mole Drain Spacing and Depth in Vertisols of Madhya Pradesh
Field experiments were conducted at farmer’s fields in Hoshangabad district of Madhya Pradesh during 2010 to 2011 to assess visual parameters and profitability of soybean as influences by mole drain spacing and depth in ... -
Impact of Alternative Ways of Acquiring Equipment on Farmers′ Competitiveness
To keep pace with competing farmers in terms of technological equipment, and thus the amount of yield and quality of those products, traditional farmers are forced to carry out the modernization of its technical and ... -
3D Discrete Element Model to Describe the Draft Force and the Influences of the Tool Geometry
Virtual DEM models were developed in correspondence with the real tests. In this article we will introduce the methods of how DEM approach was used in developing a model for the prediction of draught force on cultivator ... -
