What is the best time to apply boll fertilizer to cotton?
When is the best time to apply boll fertilizer to cotton? Here is an introduction. With boll fertilizer applied to cotton, there is no need to fear excessive vegetative growth. Some farmers worry that after applying boll fertilizer, cotton will undergo "secondary growth," staying green and late-maturing. In fact, this concern is unnecessary. First, because after cotton sets bolls in concentrated fashion, the direction of nutrient transport shifts from the main stem growing point to the fruiting branches that have set bolls; the bolls have the capacity to receive nutrients and will not cause "secondary growth." Second, the flowering and boll-setting stage is the second peak of carbon content in the cotton plant, while nitrogen content declines, soluble sugars increase, the carbon-to-nitrogen ratio is at its highest, and nutrient demand is greatest. The only fear is starving the plants, not excessive growth. Third, the middle and upper parts of the cotton plant have good ventilation and light penetration, and the boll-setting rate there can reach over 50%, more than 10 percentage points higher than the boll-setting rate in the lower part. With sufficient fertilizer, cotton can remain steady without decline.

Cotton Cultivation Techniques: How to Apply Topdressing During the Flowering and Boll-setting Stage of Cotton?
How to apply topdressing during the flowering and boll-setting stage of cotton? Please provide guidance. During the flowering and boll-setting stage of cotton, the following methods can be referenced for topdressing: 1. For plots lacking fertilizer, increase the topdressing amount. In areas with a relatively large per capita cotton planting area, some villages still maintain a low-input, low-output state, and the cotton planting benefit is very low. Some even apply only 10-15 kg of urea or diammonium phosphate per mu (with an annual seed cotton yield of more than 150 kg per mu). Now the cotton plants have shown severe fertilizer deficiency, especially in Nanpi County, where heavy rainstorms have occurred, cotton fields have accumulated water, and the limited available nutrients in the soil have been leached and lost. Topdressing is urgently needed now.
