A study was done to see how a special nano fertilizer affected the growth and early yield of eggplants in a greenhouse. They used different amounts of the nano fertilizer and compared it to regular fertilizer recommendations. The results showed that the higher amount of nano fertilizer led to taller plants, more leaves, bigger leaf area, more branches, and higher early yield. Also, using the full fertilizer recommendation resulted in taller plants and more leaves. When the high amount of nano fertilizer was combined with half of the regular recommendation, it led to more branches and higher early yield.
