A significant positive correlation was observed between pest population and maximum and minimum temperature, whereas, it was non-significant positive with average relative humidity. A non-...
Under N limitation, there was a genetic negative correlation between grain yield and grain protein concentration. Deviation from this negative relationship (grain protein deviation or GPD) was related to genotypic differences in post-anthesis N uptake. It is concluded that N uptake at anthesis was ...
