As discussed above, the following inference
could be drawn. Among the different
genotypes taken for study in the experiment
and zero tillage impact, BRW 3708 recorded
the highest value of growth attributes viz.

Plant height, number of tillers, LAI and dry
matter accumulation which follows the order
BRW 3708 > CBW 38 > DBW 39 > HD 2967
> HD 2733 > K 0307.
