The leaf area of both crops
were determined by using core borer/punch method
according to Adelana, (1980) and was estimated as
leaf dry weight multiplied by disk area divided by
disk dry weight. That is, leaf area = (leaf dry wt. x
disk area)/disk dry wt. The leaf areas of the crops
were then converted to their leaf area indices. Data
on yield components of each crops were taken
from 16m2
(4m x 4m of inter and intra- row) from
the inner rows. The data were analysed according
to the procedure of a randomized complete block
design and the treatment means were compared
using standard error of the difference between two
treatment means as outlined by Steele and Torrie
(1980). Genstat Release 4.23 Discovery Edition
statistical software package was used for the
statistical analysis of the data.
