Abstract:
Salinity and / or sodicity soil is a limiting factor for agriculturas production. especially
in arid and semi-arid regions of the world. Varying these sons recovery methods such
as washing the salts, applying chemical and organic correctives, as well as the use of
species tolerant to salta has been used. aimed to to research, evaluate the growth
and yield of cv colored fiber coüon. BRS Topaz, the second post pruning cycle in
sons with different percentages of exchangeable sodium (PST) and bovine manure.
The experiment was conducted in a greenhouse of CCTA / UFCG. It used the
randomized block design in a factorial 5 x 4, whose treatments consisted of ave
leveis of PST(13.61 22.41 30.11 39.0 and 48.0%) and four leveis of manure Bovine(0,
5,. 10 and 15% in soil volume basis, with 3 repetitions The exchangeable sodium
percentage ranging from 13.3 to 48.0% did not interfere with NF variables, AF after
31 DAP, EBF, NFP , CCP, and MPluma. was obtained most FSR PST with 20%. The
use of manure is effective in hp cotton cultivation. BRS Topaz in saline-sodic sons.
