The time of application for Protein Hydrolysate 1.5% (Plant Source) (Granules) depends on the crop type and growth stage. Generally, it should be applied during the active growth stages of the crop to maximize nutrient absorption and plant response. For most field and vegetable crops, the first application is recommended 15–20 days after sowing or transplanting, when plants begin active root and shoot growth. The second application should be made before flowering or at the early reproductive stage to promote better flower initiation and fruit or pod setting. A third application is beneficial during fruit or pod development, helping to improve yield, size, and quality. In fruit crops, applications can also be made at new leaf flush, pre-flowering, and fruit enlargement stages. For best results, the product should be applied either early in the morning or late in the evening, avoiding hot and windy periods or rainfall, to ensure effective absorption and minimize evaporation losses.
