The highest length of hollowness i.e. 8.57 cm was found at Control and the lowest length of hollowness i.e. 0.16 cm was found at 0.075% Boron (3- times spray). The mean value was found to be 2.67 cm. The highest diameter of hollowness i.e. 1.83 cm was found in control and the lowest diameter of hollowness i.e. 0.16 cm was found at 0.025% Boron (3- times spray). The mean value was found to be 0.83 cm (Table 6).
