What Fertilizer to Apply to Tobacco to Increase Yield? A Detailed Guide to Scientific Fertilization Methods
How to fertilize tobacco scientifically? The various nutrients needed by flue-cured tobacco throughout its entire field growth period are mainly absorbed from the soil. Judging from the soil nutrient conditions in tobacco-growing areas under various ecological conditions in China, whether in terms of nutrient quantity or the dynamic supply process, they often cannot satisfy flue-cured tobacco's requirements for yield and quality...
What Fertilizer to Apply to Tobacco to Increase Yield?Tobacco is a potassium-loving crop. Through our trials applying biological potassium fertilizer to tobacco, we achieved obvious results. Applying 0.5-1.0 kg of biological potassium fertilizer per mu, the average flue-cured tobacco yield per mu was 194.1 kg, an increase of 13.3% over the control, and the average proportion of medium-to-upper-grade tobacco increased by 8.8% over the control. Its yield-increasing effect was equivalent to applying 15 kg of potassium sulfate per mu, yet its value-increasing effect was superior to 15 kg of potassium sulfate, while the cost was only 1/5 that of potassium sulfate.
The biological potassium fertilizer is simple to use: first mix the biological potassium fertilizer evenly with organic fertilizer, and apply it in holes at the base of the tobacco seedlings when transplanting and establishing the seedlings. If seedling cultivation in nutritional pots is used, the biological potassium fertilizer can be mixed into the nutritional soil.
