Figure 4 Individual growth of yam for seed wt. 800 gm
Note 4: Downward trend of curves are further arrested with seed weight 800 g in Figure 4 compared to that for seed weights 500 g
and 650 g, after a favourable stimuli of plant intervention is made, as seen from growth curves with seed weight 800 g. This
indicates a positive association of seed weight with yield in nominal plant care environment
Figure 5 Growth curve of yam (seed wt. 500 g, cut at 1
st
interim)
Note: Growth curve of yam with seed weight 500 g and yam detachment at the time of first interim reading shows an upward trend
after intervention
Figure 6 Growth curve of yam (seed wt. 500 g, cut at 2
nd
interim)
Note: Growth curve of yam with seed weight 500 g, when yam detachment is made at the time of second interim reading, are shown.
An upward trend after intervention is seen. Mean response curve calculated as the mean of y computed for each fixed value of x
over grid spacing of a day shows an increasing trend. Similar observation holds for median response curve computed as median of y
values at fixed x. Points are marked on the individual growth curves, as interim readings lie in a straight line, for a number of the
times growth slopes are maintained, showing no kink
