Program for Jerusalem Artichoke (Helianthus tuberosus) Yield Predicting According to Nitrogen Dose and Rainfall



A mathematical model of yield predicting has been developed for Jerusalem artichoke. It takes in to consideration nitrogen dose and rainfall during the vegetation period. Two different mathematical equations describe relations between yield, nitrogen dose, and rainfall in the model. They are based on data from literature. A program in LabVIEW has been written which is based on the model. The program work results are appropriate and relevant to the data from literature. The program can be used to simulate the size of the yield depending on the amount of rainfall and the nitrogen dose used. It should help in forecasting the applied nitrogen doses and yielding the plantations. These results are necessary for the subsequent calculation of the economic viability of running the plantations due to the costs of the nitrogen fertilizer used and the yields obtained. They are intended to prevent the over-fertilization of plantations by nitrogen fertilizers and limits costs of implemented fertilizers.
