urea plays a vital role in flower and fruit thinning of peach trees and nectarines. Although the floral organs of these trees responded relatively slowly to urea, a higher concentration of 7.4% was required for optimal results. the optimum concentration for thinning flowers and fruits is in the range of 8% to 12%. By spraying this concentration within 1-2 weeks, farmers can successfully achieve their desired thinning results.

The multifunctionality of urea is not limited to flower thinning and fruit thinning, and its application in hybrid rice seed production technology has also been demonstrated. To maximize the number of hybrid rice seeds or to perform sterile line breeding, red blood cells are traditionally used. has prompted researchers to explore alternatives. In recent experiments, urea has shown promising results as a cost-effective alternative to gibberellins.

During the critical booting and early heading stages (20% heading stage), farmers replace gibberellin with urea at a concentration of 1.5% to 2%. This substitution effectively regulates the growth of the mother and parent plants, ensuring that their flowering periods are synchronized. By adopting urea as an alternative, farmers can reduce production costs associated with seed production while achieving comparable results.
