Abstract
Two field experiments were carried out at each of
1999 and 2000 seasons at Sakha Research Station, Kafr El
Shiekh governorate, Egypt, to study the effect of soil injection with anhydrous ammonia at two levels of soil moisture contents (11% and 26% by weight) and two soil depths (10 em and 20 em) on growth, productivity, lint quality, nitrogen uptake and seed oil percentage of the Egyptian cotton cultivar Giza 89.
Anhydrous ammonia (82 % N) was applied at a rate of
62 kg N/fed at 10 em and 20 em depth preplanting, Anhydrous ammonia at a rate of 31 kg nlfed at 10 em and 20 em depth preplanting with 31 kg N/fed as urea (46.5 % N) on the surface of the soil at thinning time, and urea (46.5% N) as a control at a rate of 62 kg N/fed on the surface of the soil divided into two equal parts, one at thinning time and the second with the following watering
Anhydrous ammonia was injected into the soil when soil moisture content was about 26% at one-foot depth in the first experiment, and 11% at one-foot depth in the second experiment. Each experiment was laid out in a randomized complete block design with four replications.
