Abstract
Two field experiments were carried out at EI-Se/W Agricultural Experim?nt
Stalion during 2001 and 2002 seasons to evaluate the effect of three differ,nt
nitrogen sources; namery ammonium sulpha te, urea and ammonium nllrat'! at two
rates (60 and 90 kg rmed.) and three splitting N doses and their interaction on yield
and Quality ot EgypUan cotton (Giza 86). A split sp'it-plot dMign wi\h 4 replicates as
used. The results obtained could be summarized as follows:
Nitrogen sources had a significant effect on planl height. number ot fruitln9
branches, number of open boUa(plant, boll weight, seed index. lint percentage,
earliness %. seed cotton yieldlfed, protein percentage, oil percentage, tbtal
chlorophyll and nitrogen content in cotton leaves. Increasing N-rafes up to 190
ItglNJfed. significantly increased plant height, number 01 lruiling branches. number ot
open bOils per plant. seed index. lint percentage, earliness percentage. Splitting N
sources three times markedly inC/eased plant height, number of open bolls per plant,
bOll weight. earliness percentage and seed cotton yield kentsr per Ieddan. The
Inleraction between N sources and N rates had slgnificanl effecl on number of open
bOlls/plent, earliness %. prolein %, 011 % and total chlorophyll in ecucn leaves. while
the interaction between N sources and number of N additions had a significant effect
on earliness percentage and total chlorophyll in cotton leaves in 2001 season only.
The interaction between N sources l( N rates x number of N additions had significant
effect on earliness %.
