Apart from abiotic stress, yield and yield components are
also infl uenced by the level of fertilizer, i.e., by management
practices. According to Fageria et al. (2011) the yield and yield
components increased along with the application of nitrogen
level upto a certain point and declined gradually thereafter.
Therefore, on the basis of yield and yield component data,
the optimal level of nitrogenous fertilizer application can be
ascertained. Higher level of nitrogen increases the grain sterility
percentage appreciably (Tables 25 & 26).
In the same situation the relationship between filled
grain percentage showed a negative relationship with the
concentration of nitrogen in the leaf as percentage. Therefore,
