Response of cotton to NP fertilizers and cropping sequences on
irrigated vertisols of the Rahad Scheme
Elfadil A. Babiker , Azhari Hamada1 and Salah B. Ahmed
Abstract:
Field experiments were conducted at Rahad Research Station in seasons
1986-87, 1987-88, 1991-92, 1992-93 and 1993-94 to investigate the
response of cotton (G. hirsutum) to NP fertilizers in varying cropping
sequences. Results revealed that yield differences due to 3N were not
significant as compared to 1N and 2N. Response to phosphorus application
at 1P and 2P were also not significant as compared to the control.
Accordingly, N-fertilizers in the range of 43-86 kg N/ha (1N-2N) are
recommended for G. hirsutum to cater for both the low input approach at
1N and the aging recommendation of 2N for the anticipated yield
maximization. Neither phosphorus nor the high rate of N (3N) application
are recommended for cotton (G. hirsutum) based on the evidence presented
in this paper.
