The first part of the experiment was carried out
using two cassava varieties , viz., Nanzhil99 and SC8 ,
in randomized block design of 36 plots, each measuring
1.0 mx16.0 m. Twenty plants of cassava were planted
in each plot at 0.8 m x1.0 m at the line spacing and
plant spacing of cassava , with 20 plants per plot. The
plants were treated three times with CPPU ( 1%o
solution ) , first at the expansion stage ( August 20 ,
2009) and then at the interval of 10 days. Treatments
were as follows: (i ) both sides of leaves were sprayed
with CPPU; (ii) ) the plants root were irrigated with
CPPU solution; (iii) foliar spray + irrigation of CPPU;
(iv) Control (spray and irrigation with water ). Each
treatment was replicated thrice.
