Efficiency of N uptake by wheat, as affected by time and rate of application, using N15-labelled ammonium sulphate and sodium nitrate
The efficiency of N uptake by wheat was studied in field experiment, using N15-labelled (NH4)2SO4 and NaNO3. The N rate used was 120 kg N/Ha. It was applied in three split doses (at seeding, tillering and boot st...
