Název v původním jazyce

Determination of lucerne first cut term by growing degree day method

Popis výsledku v původním jazyce

Growing degree-days (GDD) are a temperature-derived index which is related to lucerne quality and used for prediction of harvest term in the first cut. It is necessary to access these equations for different environments, thus the goal of this study is an assessment of preliminary equations in the conditions of Czech Republic. In 2004, the samples were taken over the first cut period in 10-days interval from 12 May to 22 June in the experimental field of Czech University of Agriculture Prague. There were two replications by three lucerne germplasm in this experiment. The neutrodetergent (NDF), acidodetergent (ADF), and crude fiber (CF) content was assessed by each sample. In this experiment, the correlations between GDD and fiber content were highly significant (P<0.0000) and provided R2 around 80% with residual standard deviation from 2 to 3 percentage units. According to preliminary data set, we can calculate harvest term with allowable NDF and ADF content as approximately 430 GDD in
