摘要
A method and an apparatus for determining an amount of fertilizer to be applied to grain crops are disclosed. A fertilizer application related formula for obtaining the necessary amount of fertilizer to be applied is established by analyzing growth information including leaf blade information, fertilizer application information and quality information, all the above information being obtained in advance from a number of grains or grain crops. The formula thus established is stored in the memory. The necessary amount of fertilizer to be applied for each specific period for grain crops which are presently under growth is calculated by applying to the above formula, growth information of the grain crops presently under growth and target quality information. The growth information includes leaf blade information in relation to a specific period. The results of the calculation are displayed or printed out. A method and an apparatus for estimating a quality or yield of grains prior to the harvesting is also disclosed. In this case, a quality or yield related formula is established in advance and stored in the memory.
