The common guava (Psidium guajava L.) is the most important member of the Myrtaceae family. It is reported to have originated in Central America but now has thoroughly naturalized throughout the tropics and subtropics. By virtue of its commercial and nutritional values, guava is considered a common man’s fruit and can be rightly termed as the “apple of the tropics.” Guava is of commercial importance in about 58 countries. Pakistan is ranked third among guava producing countries
Guava being a hardly plant, required less irrigation water and is not affected by extremes of hot or cold temperatures, but cannot tolerate frost.
