“…NUE is a complex agronomic traits depending on soil N availability, resulting from the efficiency of N uptake by the roots and N utilization and N remobilization by the plant [ 75 ]. Among the various traits representative of NUE, NHI was higher under NT conditions compared to CT, irrespective of the level of N fertilization.…”

A two-year experiment was conducted in the field to measure the combined impact of tilling and N fertilization on various agronomic traits related to nitrogen (N) use efficiency and to grain yield in maize cultivated in the presence of a cover crop. Four years after conversion to no-till, a significant increase in N use efficiency N harvest index, N remobilization and N remobilization efficiency was observed both under no and high N fertilization conditions. Moreover, we observed that grain yield and grain N content were higher under no-till conditions only when N fertilizers were applied. Thus, agronomic practices based on continuous no-till appear to be a promising for increasing N use efficiency in maize.

Six treat ments, i.e., 80 mM and 160 mM NaCl, 5 mM and 10 mM CaCl 2 and 80 mM + 10 mM and 160 mM + 10 mM of NaCl + CaCl 2 were given to the grow ing plants sep a rately at three de vel op men tal stages, viz., the pre-flow er ing (30 DAS), flow er ing (120 DAS) and post-flow er ing (150 DAS) stages. Each NaCl treat ment caused a sig nif i cant re duc tion in to tal plant bio mass, photosynthetic rate, stomatal con duc tance, to tal chlo ro phyll con tent, sol u ble pro tein con tent, NR ac tiv ity and ni tro gen con tent, al though nitrate con tent in creased. On the con trary CaCl 2 treat ment gave a fa vor able ef fect, com pared to the con trol. The ef fect of combined treat ments was sim i lar to that of NaCl but less in mag nitude.
