Abstract

Application of N @ 600 g/plant/year significantly enhanced the fruit yield of guava and N and Mn content of leaves, while it reduced the P, K and Zn content of leaves. Foliar spray of Zn @ 4 g/plant/year significantly increased the yield and Zn content of guava leaves. However, it reduced significantly the Mn content of leaves. Similarly, foliar spray of Mn @ 4 g/plant/year significantly increased the fruit yield, N and Zn content of leaves, while it decreased Zn content of guava leaves.
