A study was done on greengram plants to see how boron and zinc levels affect growth and yield. They sprayed boron on the leaves and added zinc to the soil at different levels. The best results came from spraying boron twice and using a higher level of zinc. This led to taller plants, more branches, nodules, and pods, as well as higher grain and straw yields. So, spraying boron and adding zinc can help greengram plants grow better and produce more.
