A study was done to see how adding different amounts of phosphorus and micronutrients to rice plants affects their growth and yield. They tested 10 different combinations and found that using 70 kg/ha of phosphorus and 10 kg/ha of zinc resulted in the best outcomes, with taller plants, more tillers, heavier plant weight, more panicles, more grains per panicle, higher test weight, grain yield, straw yield, and harvest index.
