Reduction of marginal yield in cereal crops production and possibilities to increase their yield

This paper analyses and evaluates production of cereal crops indicating the importance of agricultural and economic development, but it also elaborates on causes and consequences of decreasing production and use of cereals. In the Republic of Croatia cereal crops make up for more than two thirds of the total sowed area. Maize is the dominant cereal crop ; it covers 56% of total sowed area. Wheat has a share of 33% of total sowed area and is produced mostly on family farms. Analysis of marginal cereal crop yield in the Republic of Croatia throughout a longer period of time confirms that changes in the yield are not uniform, but they fluctuate around the average yield and development trend. The direction and intensity of changes in shorter intervals do not have these identical characteristics. This, as well as the fact that cereal yields in the Republic of Croatia are not always satisfying when compared with the results achieved in the European Union, indicates insufficient exploitation of the genetic potential of cereal crops. This paper focuses especially on the analysis of achieved level and dynamics of yield increase and determination of those factors that limit the dynamic development of cereal crops production.
