last final thesis of umer

Leaf Area: (LA = maximum leaf width (cm) x Leaf length (cm)), so five leaves from the middle
part of five sample plants were measured in each rows.
Number of branches per plant: Number of branches per plants were counted taking five
sample plants randomly.
3.6.3. Yield and yield components
For maize
Number of ears per plant: The number of ears were taken from five random plants per plot at
harvest and the mean value was calculated.
Ear length (cm): This was recorded from the measure of five randomly sample plants ear length
at harvest.
Thousand kernel weight (g): weight of 1000 kernels taken randomly from samples used for
grain yield analysis.
Grain yield (kg ha -1 ): This refers to the weight of grain harvested from the central three rows of
the net plot. Grain yield was then converted in to adjust yield for the analysis by using this
formula. Adjusted yield=AGY-(AGY*0.1)
Aboveground biomass (kg ha -1 ): This was measured based on central three rows of the net plot
plants at harvest time after sun drying, and was changed to per hectare using respective plant
weight for each treatment.
Harvest index (HI): This was the ratio of grain yield to aboveground biomass multiplied by
100.
HI =
Grain yield
