“…It should be noted that the N-utilization coefficient for winter wheat for the white lupin residues was 59.0% in the control and 61.9% in the N-fertilized subplots (Table 4). These results are similar to other studies, e.g., according to Rutkowska and Pikuła [26], the percentage of N derived from fertilizers was significantly greater in wheat (56%) compared to field pea (15-17%).…”

A field experiment was carried out in 2016–2018 in a white lupin (Lupinus albus L.)-winter wheat (Triticum aestivum cv. ‘Bogatka’) crop rotation. The aim of this study was to determine the amount of nitrogen (N) that was biologically fixed by the white lupin crop in the first year of the rotation and to estimate how much of this N was then taken up from the lupin residues by winter wheat in the second and third years of the rotation. Biologically fixed N was determined by the isotope-dilution method (ID15N) by applying 30 kg N ha−1 of 15N-labeled fertilizer (15NH4)2SO4 (containing 20.1 at.% 15N) to the white lupin and the reference plant spring wheat. The yields of white lupin seeds and crop residues were 3.92 t ha−1 and 4.30 t ha−1, respectively. The total amount of N in the white lupin biomass was 243.2 kg ha−1, which included 209.3 kg ha−1 in the seeds and 33.9 kg ha−1 in the residues. The 15N-labeled residue of white lupin was cut and ploughed into soil. Our results indicate that 111.2 kg N ha−1 was fixed from the atmosphere by the lupin plants, with 93.7 kg ha−1 found in the seeds and 17.5 kg ha−1 in the residues. In the second and third years of the rotation when winter wheat was cultivated, the plots were divided into two groups of subplots (1) without N-fertilization (control) and (2) with an application of 100 kg N ha−1. In the first year of winter wheat cultivation, 20.0% and 21.0% of N from the crop residues was taken up by the control and N-fertilization plots, respectively, while in the second year, uptake was lower at 7.12% and 9.27% in the control and N-fertilized plots, respectively.

“…The influence of the fertilizer N timing can also be understood from the higher NDFS contribution in the early N application groups. The NDFS commonly overcame the NDFF contribution in cultivated crops [ 44 , 52 ]. However, increased contribution of NDFS has often accompanied by more N asynchrony [ 13 , 42 , 53 ], as well as in the N-OATS and N-PLANT groups.…”

Early fertilizer nitrogen (N) application on cover crops or their residues during the off-season is a practice adopted in Brazil subtropical conditions under no-tillage corn (Zea mays L.) systems. However, the effect of early N application on yield, plant N content, and N recovery efficiency (NRE) for corn is not yet well documented. Five fertilizer N timings in an oat-corn system were evaluated in two studies utilizing an isotopic-labeled N determination, 15N isotope. The N fertilization timings were: (i) oat tillering, (ii) 15 days before corn planting time, over the oat residues, (iii) at corn planting time, (iv) in-season at the three-leaf growth stage (V3), and (v) in-season split application at V3 and six-leaf (V6) growth stages. Based on the statistical analysis, the N fertilization timings were separated into three groups: 1) N-OATS, designated to N applied at oat; 2) N-PLANT, referred to pre-plant and planting N applications; and 3) N-CORN, designated to in-season corn N applications. Corn yield was not affected by the N fertilization timing. However, the N-CORN N fertilization timings enhanced NRE by 17% and 35% and final N recovery system (plant plus soil) by 16% and 24% all relative to N-OATS and N-PLANT groups, respectively. Overall, N-OATS resulted in the largest N derived from fertilizer (NDFF) amount in the deeper soil layer, in overall a delta of 10 kg N ha-1 relative to the rest of the groups. Notwithstanding corn yield was not affected, early N fertilization under subtropical conditions is not a viable option since NRE was diminished and the non-recovery N increased relative to the in-season N applications.

“…The yield was higher for mixtures harvested at the stage of flat green pod of field pea. Also studies by Staniak et al (2012), Bojarczuk et al (2014) and Rutkowska and Pikuła (2016) revealed that legume/cereal mixtures harvested at a later growth stage produced more biomass.…”

The paper presents results of a research conducted between 2010 and 2012 to determine the effect of the proportion of components in a mixture and harvest date on yield and chemical composition of field pea/oat (Pisum sativum L., Avena sativa L.) mixtures. Two factors were examined in the study: factor I − proportion of components in a mixture: field pea 100%, oat 100%, field pea 75% + oat 25%, field pea 50% + oat 50%, field pea 25% + oat 75%; factor II − harvest date: the stage of field pea flowering and the stage of flat green pod of field pea. The following characteristics were examined: green matter yield of field pea/oat mixtures, nutrient content, NDF and ADF content. The results were statistically analysed. The highest fresh matter yield was produced by the 50% + 50% mixture of field pea and oat. Field pea/oat mixtures harvested at the stage of field pea flowering contained more total protein, crude ash and digestible nitrogen-free extracts. The mixtures harvested at the stage of flat green pod of field pea were higher in crude fibre, fibre fractions (NDF, ADF) and crude fat.
