Plant tissue testing is another tool for use in achieving a high degree of precision in fertilizer management. Timely tissue testing can help diagnose suspected nutrient problems or can simply assist in learning more about fertilizer management efficiency.
Cotton production in India has stagnated at a level far below its potential - the main reason being unbalanced and low rates of fertilizers. A review of key research on improved potassium (K) management practices provides a clear picture of the potential yield and economic benefits available to farmers.
Proper plant nutrition is essential for successful greenhouse production of floricultural crops. As growers move towards substrates that do not contain mineral soil, micronutrient status of substrates and plants becomes more important.
The soybean aphid has become the most important insect pest of soybeans in the North- east and Midwest regions of North America. It often damages soybean plants that are K-deficient more than those that are not.
Knowledge of potassium (K) requirements for cotton growth and development is needed for efficient production. Fertilization of cotton with K is a complex issue, because soils vary widely in terms of K-supplying capacity and K fertilizer adsorption.
Potassium is important in optimizing both crop yield and economic quality. Root activity and K uptake are generally reduced during the reproductive phase of crop development.
