Effect of irrigation with mixed water intervals and nitrogen fertilization rates on technological characters of Egyptian cotton (variety giza 83) [electronic resource].

Includes reference.

Two field experiments were carried out at Kom Oshem, EJ-fayom govemOl"ale during 2001 and 2002 seasons ,to study the effect of lITigation intervals with mixed water (Nile water +drainage water by 50%)and nitrogen fertilization rates on technological characters of egyption cotton variety Giza 83 irrigation intervals were 8.10,12,14 and 16 days. Nitrogen fertilization rates were 25,50,75,and 90kg N/feddan. The obtained results showed that average fiber fttteness(micronair reading ), fiber length at 25% span length, unifonn1ty ratio%, fiber strength and fiber elongation% were significantty affected by irrigatron intervals and nitrogen fertilization rates was achieved in both, seasons, The highest tiber .Iength at 2.5% span length with irrigated every 10 days and fertilization with 75kg N/feddan.
