Effect of Different Fertilizer Doses with Different Combinations on Cotton Growth and Yield

Fertilizers are used to provide the nutrient supply that is necessary to improve crop yield. This study was conducted to observe the effects of different doses and combinations of fertilizers on cotton growth and yield. A field was divided into six areas, each treated with different combinations of four different types of fertilizers: urea, nitrogen phosphorus (NP), diammonium phosphate (DAP), and calcium ammonium nitrate (CAN). Our results showed that if all the nutrients are balanced, a moderate dose and timely application of fertilizers can increase plant growth and improve crop yield.
