This study includes (9) treatments which are resulted form three levels of humic acid ( 0 , 30 , 40 )g/m2 with 3 dates of added at (15 , 30, 45 days ) from transplanting and their effect on vegetative and fruit growth .

The experiment adopts the Split Plot Design (SPD) within RCBD with three replicates and the means are compared to Duncan's Multiple Range Test at the probability level of 0.05.

Results show superiority of all concentrations of humic acid treatments significantly as compared with control treatment in all vegetative growth and fruiting properties and the interaction of is C×T significantly affected the above parameters to control treatment for the four pickings ( 2 , 4 , 6 , 8 ) , for recipes studied .

The treatment dates added have more than the first date on the other two date for prescription rate of plant height (cm) of the four pickings and the results are ( 115.3 , 120.4 , 130.7 , 145.4 ) cm , respectively .While the number of leaves / plant and the area cm2 / plant the second and the third date is superior on the first date , while the number of fruits / plant for the third date has significant above the picking (4, 6 , 8) and the results are ( 20.37 , 19.84 , 13.70 ), fruit / plant , respectively .

Whereas fruit weight in first and second dates are superior.

Either recipe yield plant kg / plant outweigh the second date of the another dates and for the four pickings ( 2, 4, 6, 8 ) are ( 0.719 , 2.058 , 2.842 , 3.490 ) kg / plant , respectively
