“…In the typical Polish soil conditions, rye ( Secale cereale L.) is the cereal species with the most efficient root system. The value of the rye genome (R) has been confirmed in hexaploid triticale ( xTriticosecale Wittmack, genome formula AABBRR), the species showing a remarkable improvement, in relation to wheat ( Triticum aestivum L. – AABBDD), in the uptake of mineral nutrients (Paponov et al. 1999, Ciepły and Oracka 2001).…”

Two sets of disomic substitution lines, derived from the cultivars ÔPrestoÕ and ÔRhinoÕ of triticale, with rye chromosome pairs replaced by their wheat D-genome homoeologues, were tested in hydroponic culture for nitrogen and phosphorus uptake and utilization efficiency. The effect of a substitution on the amount of absorbed nutrients was predominantly negative and proportional to the effect on plant dry matter. Significant decreases were found for the substitutions 5D(5R), 6D(6R) of both cultivars, 2D(2R), 4D(4R) of ÔPrestoÕ and 3D(3R) of ÔRhinoÕ. On the other hand, the nitrogen utilization efficiency was significantly increased in all substitution lines, with the exception of the 1D(1R) ones. The differences in phosphorus utilization were generally positive, but less pronounced, and significant only in the lines 2D(2R) and 6D(6R). The data suggest that presence of both rye and D-genome chromosomes is conducive for the best effect of the applied N and P fertilizers.

“…Here, mean RLD values of the 3 minirhizotron replicates of each soil type and an assumed average SRL value of 100 m g -1 were used. This SRL value was estimated from a range of values reported in the literature for wheat, such as: 17-24 m g -1 (Meena et al, 2013), 15-150 m g -1 (Wang et al, 2014), 90-120 m g -1 (Paponov et al, 1999), 150 m g -1 (Wilhelm et al, 1982), and 173-93 m g -1 (Løes and Gahoonia, 2004).…”

Agricultural soil landscapes of hummocky ground moraines are characterized by 3D spatial patterns of soil types that result from profile modifications due to the combined effect of water and tillage erosion. We hypothesize that crops reflect such soil landscape patterns by increased or reduced plant and root growth. Root development may depend on the thickness and vertical sequence of soil horizons as well as on the structural development state of these horizons at different landscape positions. The hypotheses were tested using field data of the root density (RD) and the root lengths (RL) of winter wheat using the minirhizotron technique. We compared data from plots at the CarboZALF‐D site (NE Germany) that are representing a non‐eroded reference soil profile (Albic Luvisol) at a plateau position, a strongly eroded profile at steep slope (Calcaric Regosol), and a depositional profile at the footslope (Anocolluvic Regosol). At each of these plots, three Plexiglas access tubes were installed down to approx. 1.5 m soil depth. Root measurements were carried out during the growing season of winter wheat (September 2014–August 2015) on six dates. The root length density (RLD) and the root biomass density were derived from RD values assuming a mean specific root length of 100 m g−1. Values of RD and RLD were highest for the Anocolluvic Regosol and lowest for the Calcaric Regosol. The maximum root penetration depth was lower in the Anocolluvic Regosol because of a relatively high and fluctuating water table at this landscape position. Results revealed positive relations between below‐ground (root) and above‐ground crop parameters (i.e., leaf area index, plant height, biomass, and yield) for the three soil types. Observed root densities and root lengths in soils at the three landscape positions corroborated the hypothesis that the root system was reflecting erosion‐induced soil profile modifications. Soil landscape position dependent root growth should be considered when attempting to quantify landscape scale water and element balances as well as agricultural productivity.

“…Studies on N supply have consistently shown positive correlations between S:R and shoot N % which were independent of nutrient effects on overall growth (e.g. Caloin et al, 1980;Andrews, 1993;Paponov et al, 1999). Andrews et al (1999Andrews et al ( , 2001 proposed that shoot protein concentration may have a key role in determining S:R under a wide range of environmental conditions and could provide the basis of a mechanism for the effect of a range of different nutrient deficiencies.…”

Annals of Applied Biology, Association of Applied Biologists, 143, (2), 215-229. Sponsorship: Government of PakistanThree experiments examined effects on growth, dry matter partitioning and nutrient uptake in potato plants grown in large pots under different combinations of adequate and deficient levels of nitrogen, phosphorus and potassium. N supply affected the growth of all leaves, with low N reducing both the size of individual leaves and the extent of branch growth. P and K availability affected the growth of later formed leaves and only when both were deficient was branch growth substantially reduced. At later stages of growth, total green leaf area was significantly reduced by deficiency of each of the nutrients. Partitioning of dry matter to tubers was markedly reduced by K deficiency and increased in one experiment by P deficiency. When both P and K were deficient, partitioning approximated that under non-limiting conditions. Leaf weight ratio (LWR) was higher under K deficiency, but not when P was also deficient, and was consistently higher when the ratio of K : P in dry matter was less than approximately five. In these experiments, LWR was not consistently related to shoot N% and N supply had relatively little effect on partitioning. There were large treatment effects on tuber dry matter percentage, characterised by significant interactions especially between N and K. Deficiency of one nutrient increased the concentration of others but uptake was highly regulated as crop content of all three nutrients was reduced when the supply of any one was deficient. The results show that the response of potatoes to single deficiencies may be influenced greatly by the levels of other nutrients.Peer reviewe
