Nitrogen Acquisition of Pea-Oat and Pea-Canola Intercrops and Their Impact on Subsequent Wheat Crops
… percentage of N derived from the atmosphere (%Ndfa), %N transfer, N fertilizer recovery, and residue recovery in the succeeding wheat crop. The %Ndfa measured the percentage of N in pea that was derived from the atmosphere. In contrast, biological N fixation (BNF) determined the amount of N …

Impact of free-living diazotrophs, Azospirillum lipoferum and Gluconacetobacter azotocaptans, on growth and nitrogen utilization by wheat (Triticum aestivum cv. Lillian)
… amount of fertilizer N increased, so did the %Ndfa and N uptake. In the growth chamber study, inoculated wheat, and fertilized with 12.2 and 24.5 µg N g-1 had the highest %Ndfa of 25.5%, and wheat fertilized with 24 µg N g-1 had the highest N uptake (1.3 g pot-1) at maturity. In the field …

N₂ fixation, plant mineral nutrition and C metabolites in cowpea/maize cropping systems
… than in maize. The %N derived from fixation (Ndfa) was similar for sole, intra and intercropped cowpea. However the amount of N fixed was significantly greater in sole cowpea compared to intra- and intercropped cowpea. When nutrient uptake and assimilation was assessed in the cropping system, …

Mungbean [Vigna radiata (L.) Wilczek]: Protein-rich Legume for Improving Soil Fertility and Diversifying Cropping Systems
… millet alone. The N2 fixation study showed that %Ndfa of mungbean was higher when grown in the loamy sand soil (27% increase). However, soil N uptake (235 mg plant⁻¹) and amount of N fixed (67 mg plant⁻¹) were greater in the silt loam soil. Among genotypes, IC 8972-1 significantly (p≤ 0.05) …
