For centuries, the vast majority of tropical countries have planted (Hayes, 1970, etc.). In India, especially in the southern states, fruit has become a commodity fruit. Its fruit needs 10 to 10 and a half months from flowering to maturity. The fruit growth curve belongs to the “double S” type with obvious three phases before stagnation, stagnation and stagnation (Sulladmath et al., 1979). In 1979, Rao reported that the highest K content was found in ripening kernels, and the Mg content was higher than that of Ca
