| Abstract | ||||
| Two field experiments were conducted at Sakha Agricultural Research Station at Kafr El-Sheikh Governorate, Egypt, during the growing seasons of 2011 and 2012 the objective of this investigation was aimed to determine the suitable agricultural managements such as planting date, planting patterns (row width + hill spacing) and nitrogen fertilizer level) for evaluation new promising hybrid cotton [Giza 84 (Giza 70 x 51B)] Pima 62. Experiment design was conducted in split-split plots design with four replications. The main plots involved the two planting dates (early on 15 April and late on 15May planting), The sub plots involved four planting patterns (65 cm row width +25 cm hill space, 60 cm row width + 35 cm hill space, 90 cm row width + 35 cm hill space planted in two sides and 90 cm row width + 40 cm hill space planted in two sides) and the sub-sub plots included three nitrogen fertilizer levels (30, 45 and 60 kg N /fed.) Results indicated that early planting date on 15th April significantly increased seed cotton yield/fed due to the increase number of open bolls /plant and boll weight. The planting pattern (65 cm row width + 35 cm hill space) gave the good values of number of opining bolls and seed cotton yield per fed.. 45 kg N fertilizer levels significantly increased number of bolls per plant and gave good values of number of fruiting branches, boll weight, seed index and seed cotton yield. Early planting with planting pattern (65 cm row width + 35 hill space) gave the highest values for all growth and yield and yield components. The early planting and 45 kg N fertilizer interaction gave the highest values for boll weight, no. of bolls /plant and seed cotton yield/fed. The planting pattern 65 cm row width + 35 cm hill space and 45 kg N fertilizer gave the highest values for no. of bolls/ plant and seed cotton yield/fed. Early planting, planting pattern (65 cm row width + 35 cm hill space) and 45 kg N fertilizer interaction gave the highest values for boll weight, no. of bolls/plant and seed cotton yield/fed. The studied treatments did not exhibit significant effect on all fiber properties. It could be concluded that for maximizing seed cotton yield/fed produced from sown new promising hybrid cotton [Giza 84 (Giza 70 x 51B)] Pima 62 early on 15th April, at planting pattern (65 row width + 35 cm hill space) and fertilizing with 45 kg N/fed under Kafr El-Sheikh condition. | ||||
