Each experimental unit of 15 m 2 ascending to a total of 45 m2 in which one carries out manua: deshierbo, fertilization and it harvests, in the soca cultivation intermittent waterings and periodic floods were used, you fertilizes to reason of 100-50-80 complementary dose in 2 times to the equivalent 1 O days at 60% of urea and the second to the cotton point to the equivalent 50 days to 40% of the rest of urea. The obtained results indicate that among the studied e treatments highly significant difference existed for the grain yield standing out the stubble cut to the same day, 3 and 6 days after the crop in plant with 4446,67; 4000,00; 3900,00 kg/ha followed by the other treatments with 3380,00; 3260,00; 3020,00; 2833,33; 2733,33; 2706,67; 2633,33; 2360,00 and 2320,00 kg/ha to 14% of humidity approximately.
