Method of using/applying a keratin hydrolysis peptide solution upon coffee plants to increase fruiting yield and weight

A method of using a keratin hydrolysis peptide (KHP) solution to coffee plants for the enhancement of the fruiting weight and yield, comprising the steps of:

• a. Preparing the KHP solution by preparing and putting 70 kg of feathers whose content is 46% water in a sealed container;
• b. hydrolyzing the mixture in the container with a temperature and pressure setting of 180° C. and 13 kg/cm2 for a duration of 40 minutes;
• c. using a mass spectrometer to confirm the combination of peptides in the solution to contain at least 253 peptides as listed in the specification where their molecular masses are between 500 and 4,000 Daltons, and the concentration is in the range of 2.0×105˜4.5×105 ppm;
• and
• d. applying the solution to the leaf surface of the coffee plant.
