Effect of foliar urea spraying and nitrogen application at sowing upon dry matter and nitrogen distribution in wheat (<i>Triticum aestivum</i> L)

The effects of foliar urea spraying at field level at 3 different developmental wheat stages upon grain yield, its components, and N accumulation and distribution within the plant were studied on Buck Pucará, a cultivar with Mexican germplasm and high grain yielding potential. Plants were grown at 2...

description The effects of foliar urea spraying at field level at 3 different developmental wheat stages upon grain yield, its components, and N accumulation and distribution within the plant were studied on Buck Pucará, a cultivar with Mexican germplasm and high grain yielding potential. Plants were grown at 2 N levels: no N and 100 kg N ha applied at sowing as granular urea, without (control) and with foliar urea spraying (20 kg N/ha) at the end of tillering (T₁), at anthesis (T₂), or 14 days after anthesis (T₃). Spraying at T1 increased ear number/m², biological yield, grain yield, harvest index, total N uptake and nitrogen harvest index. It also increased grain set, without affecting fertile spikelet/spike. Spraying at T₂ or afterwards, increased grain %N and plant %N at maturity but did not improve N allocation in the grain, grain yield and its components. Spraying at T₁ only increased grain %N, total %N and %N of the vegetative organs when N availability at sowing was high.
