J.OkeleyeK. A.OloweV. I.O.AjayiE. O.5200725A field trial was conducted at the Teaching and Research Farm
of the University of Agriculture, Abeokuta (latitude 7°15 N and longitude
3°25 E) located in the forest-savanna transition zone of south west
Nigeria in 2002 and 2003 to assess the yield and economic potentials of intercropping
two cassava morphotypes (TMS 30572, branching and TME 1, non-branching) and
rice varieties (WAB 189-B-B-B-6-HB, ITA 150 and ITA 321). Significant differences
was observed among the rice varieties as ITA 321 produced the highest grain
yield (3.50 and 3.56 t ha-1) under sole in 2002 and 2003, respectively.
Similarly under intercropping with both cassava cultivars it recorded the highest
grain yield in 2002 and 2003. On the average intercropping significantly reduced
the grain yield of rice intercropped with TMS 30572 and TME 1 in 2002 and 2003.
In 2002, tuber yields of the two cassava cultivars in mixtures were similar
to the yields of their corresponding sole. However, in 2003, sole cassava TMS
30572 and TME 1 produced significantly higher tuber yield than their corresponding
intercrops. Rice/cassava intercrop on the average resulted in land equivalent
ratio (LER) of 1.88 and 1.79 in 2002 and 2003, respectively indicating an advantage
of intercropping rice with cassava. Also a high level of compatibility was observed
as the land equivalent co-efficient in 2002 and 2003 was high especially in
2002 (0.52 and 0.88). The intercropping of rice with cassava gave a higher total
net income of intercropping than sole crop as TMS 30572 intercropped with ITA
321 gave a higher total net income (
377,100.00) than TME 1 intercropped with ITA 321 (
355,800.00).]]>Adetiloye, P.O., F.O.C. Ezedinma and B.N. Okigbo,19831912739Aggarwal, P. and D.
