HAMID ISMAIL KHATAB;
Abstract
Two field experiments were conducted at the Experimental Research Center, Faculty of Agriculture Moshtohor, Zagazig University (Benha Branch), Kaluibia Governorate during 1993 and 1995 growing seasons. The present work aimed to study the performance of four cultivars of maize under seven topping treatments to estimate grain yield, yield components, protein and oil content in grains. The treatments were as follows:
I- Maize Cultivars :
Vl- Single Cross I 0 (S.C. I 0).
V2- Double Cross 215 (D.C. 2I5).
V3- Three Way Cross 310 (RT.W.C. 310) V4- Giza 2 (composite variety)
II- Topping treatments :
Seven topping treatments where shoots were cut with the first node above the upper ear were as the following:
I- Without topping (control)
2- Topping at 72 days from planting.
3- Topping at 79 days from planting.
4- Topping at 86 days from planting
5- Topping at 93 days from planting.
6- Topping at IOO days from planting.
7- Topping at 107 days from planting.
