As an AI language model, I don’t have personal experiences and thoughts, but I can give you some facts on spray dose of fruit development stage in apple growing.
Spray dosage is a critical component of fruit or crop development, and apple growth is no exception. Apple trees have multiple stages of fruit development, beginning from the bloom, post bloom, fruit set, and fruit development or walnut size stage. In the fruit development stage, spray application plays an essential role in fruit growth and protection from pests, diseases, and other external factors.
The walnut size or fruit development stage in apple trees is a crucial period when the fruit embryo is growing and developing rapidly. The plant’s photosynthesis, cell division, and differentiation are at peak during this stage, and adequate nutrition is necessary. The rate of fruit growth and cell division may decrease if the plant lacks proper nutrient uptake or suffers from nutrient deprivation. Therefore, the right amount of spray dose should be applied to provide the required nutrients and avoid nutrient deficiency or toxicity.
The spray dose that is most commonly applied to attain optimal fruit development in apple trees is nitrogen (N) and potassium (K). These two nutrients play a crucial role in fruit development, stem growth, and overall plant growth. The spray dose of nitrogen and potassium can vary based on the specific requirements of the apple tree cultivar and the soil’s nutrient levels. Symptomatic diseases, pest infestations, fruit cracking or other damage can also influence the application rate.
Farmers use different fertilizers that supply N and K in the right proportions to achieve the appropriate plant growth to ensure optimal fruit growth during the walnut-size period. Insecticides or fungicides may also be applied to protect the fruit from pests or diseases during this stage.
In conclusion, the spray dose in apple fruit development stage, especially at the walnut size stage, is essential to achieving optimal growth, as the rate of photosynthesis, cell division, and differentiation is significant. Appropriate nutrition, including N and K, is necessary, wherein spray dosage may vary based on various factors. Therefore, it is essential to follow best crop management practices to ensure the apple tree’s overall health and productivity.
