Comparing the treatment means it can be
concluded that manure 2 is the best
among the manures and irrigation sched-
ule 3 is the best irrigation schedule. Simi-
larly by using appropriate critical
difference values as mentioned above,
one can find out the best manure at a
particular irrigation level and vice versa
(Table
10.25
).
