Abstract

The author of this paper recongnised the modification of both quantity and quality of grape and peach by changing the order of givingtime of nutrients N, P, K. Liebig's law is adaptable only within a limit, and out of the limit it is not usable when the order of giving time ofthe same nutrients and of the same quantity is changed. A ratio of nutrients therefore is sometimes favourable and sometimes harmful, it gives good result only when it fitted itself to the nutrioper iodism that the authorhas found lately. The vegetative organ demands much N, the generative organ requires much P and for the maturation only K is favourable. N given at the time of maturation causes the reaction of the development and the yield of fruits is smaller and their quality is poorer.
