Effect of cropping system on yield of some sweetpotato and okra cultivars in an intercropping system

SC Njoku, AO Ano, LEF Amangbo

Abstract


A field trial was conducted for 2 years to determine cropping system effect on yield of some sweetpotato and okra cultivars in an intercropping system. Sweetpotato variety TIS 87/0087 produced significantly (P<0.05) higher number of tubers per plant than Tis 8164 and Tis 2532.op.1.13 varieties. Tuber yield was also significant in 2000, but was not in 2001. Intercropping generally increased okra plant height while interaction of okra with  sweetpotato and cropping system showed significant differences in pod length and pod width. The land equivalent ratio of sweetpotato and okra cultivar were all above 1.0 indicating that higher productivity per unit area was achieved by growing the two crops together than growing them separately.
