Yield Formation in the Spring Barley in Organic Farming
Original language description
In a fifteen-year experiment with 21 European varieties of spring barley in organic farming system in a fertile area, the stability of the yield, specialties of yield formation and its structure were evaluated. The current varieties of spring barley formtheir yields by the number of ears per unit area and thus, they are dependent on productive tillering. A great variability in the yield has been determined ? the coefficient of variation was 28 %, average yield 4.47 t/ha, and standard deviation s= 1.27t.ha-1. This variability was caused by the great dependence of the tillers formation on weather conditions and on the quantity of nitrogen available for their establishment and growth. Tillering period is very long and open to a direct influence of changeable weather.
