“…Conversely, several researchers described that the yield was not improved, or even reduced by no-tillage practice (Lal et al, 1989;Oyanagi et al, 1998;Jug et al, 2006). Similarly, in our field no positive effect of no-tillage on soybean yield was found during the first three years of wheat-soybean rotation, and correlation between root traits and yield was not found (Izumi et al, 2004). However, in the present study soybean under the no-tillage condition, which developed greater roots both in length and weight, and thicker and shallower root system as compared with that under the tilled condition (Table 1), had significantly larger shoot biomass and yield (Table 4).…”

“…Frederick and Bauer (1996) reported that the deep tillage with no-surface tillage was more effective than that with disc tillage on the yield of winter wheat, although such trend was not recognized in this study. The positive effect of notillage had been already observed from the third year of wheat-soybean rotation in the same field (Izumi et al, 2004). In this study, conducted at the sixth year, while the amount of root itself did not significantly differ (Table 2), distribution ratio of roots in the 5−20 cm layer was higher in no-tillage than in the tillage treatment (Table 3).…”

“…1), and the plants did not show severe drought symptom. In fact, root traits such as RLD and SRL were quite comparable to those in the second year when there was plenty rainfall in summer (Izumi et al, 2004). Therefore, depletion of soil moisture was probably not a critical limiting factor on yield, though no-tillage soybean roots tended to distribute near the surface as was prospected.…”

“…rotation, both of which are expected as alternative crops for paddy rice field in Japan, aiming to elucidate how the different tillage practice affect root system development, shoot growth, water uptake, and yield (Izumi et al, 2004;Iijima et al, 2007). We found that the continuous no-tillage practice improved the soil condition for root development and resulted in an enhancement of the shoot growth and yield in wheat, and comparable yield was acquired in soybean for three years, i.e., first to sixth cropping season (Izumi et al, 2004). However, through the next two years (the seventh to tenth cropping season) yield of wheat gradually decreased and that of soybean tended to stagnate (not published), and the water uptake from deep soil layer was limited under the no-tillage (Iijima et al, 2007).…”

Roots play a major role in plant development. Their study in field conditions is important to identify suitable soil management practices for sustainable crop productions. Soil coring, which is a common method in root production measurement, is limited in sampling frequency due to the hand-sorting step. This step, needed to sort roots from other elements extracted from soil cores like crop residues, is time consuming, tedious, and vulnerable to operator ability and subjectivity. To get rid of the cumbersome hand-sorting step, avoid confusion between these elements, and reduce the time needed to quantify roots, a new procedure, based on near-infrared hyperspectral imaging spectroscopy and chemometrics, has been proposed. It was tested to discriminate roots of winter wheat (Triticum aestivum L.) from crop residues and soil particles.Two algorithms (support vector machine and partial least squares discriminant analysis) have been compared for discrimination analysis. Models constructed with both algorithms allowed the discrimination of roots from other elements, but the best results were reached with models based on support vector machine. The ways to validate models, with selected spectra or with hyperspectral images, provided different kinds of information but were complementary. This new procedure of root discrimination is a first step before root quantification in soil samples with near-infrared hyperspectral imaging. The results indicate that the methodology could be an interesting tool to improve the understanding of the effect of tillage or fertilization, for example, on root system development. conditions. The potential of plants to obtain water and mineral nutrients from the soil is primarily attributed to their capacity to develop extensive root systems.2 Studies on root development are important for a better understanding of the interaction between crop root systems and the growing environment to identify suitable soil management practices for sustainable crop productions. 4 The time taken by roots to colonize the deep soil profile and the root system biomass production during the whole crop development cycle are therefore good indicators to interpret crop behavior in various management modes and in a given soilclimate context. Nevertheless, roots are rarely directly evaluated in field experiments because soil limits accessibility for their observation. 1,5 Therefore, they need to be extracted from soil before any measurement can be made.Soil coring is a commonly used method to sample roots in field experiments and measure their production. 6 This technique is not expensive and allows repeated measurements during crop growth at several soil depths. After soil coring, cores need to be washed to extract roots from soil. Others elements, mainly crop residues buried in crop soils, are also extracted during the washing step and need to be separated from roots, commonly by hand-sorting, before any analysis or quantification of roots. 1,4,5,[7][8][9][10] This sorting step is time-consuming, tedious, an...

Root length density of cereal and grain legume crops grown in diverse rotations

The development of crop rotations to support sustainable agriculture depends on understanding how crop rotations affect above‐ and belowground crop characteristics. Our objectives were to investigate crop rotation effects on shoot dry weight and root characteristics of cereal and grain legume crops at anthesis, as well as on grain yield. Rotations were corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] (CS), corn–soybean–spring wheat (Triticum aestivum L.)–field pea (Pisum sativum L.) (CSSwP), corn–soybean–spring wheat–sunflower (Helianthus annuus L.) (CSSwSf), corn–field pea–winter wheat–soybean (CPWwS), and corn–oat (Avena sativa L.)–winter wheat‐soybean (COWwS). Crop biomass and root samples were collected at crop anthesis for each crop within the crop rotation. Two soil cores were taken within each of the crops grown in rotation, and the two soil cores were cut into segments of 0–15, 15–30, 30–45, 45–60, 60–90, and 90–120 cm and combined for measuring root length density. Rotations were established in 2000 with plants measured in 2015 and 2016. Rotations had no significant effects on shoot dry weight at anthesis. Small grains had greater root length density than grain legumes between 0‐ and 60‐cm soil depths. Rotation treatments had significant effects only on soybean root length density at 0‐ to 90‐cm soil depths. Soybean following winter wheat (CPWwS and COWwS) had significantly less root length density than soybean following corn. Soybean grain yield was significantly greater following winter wheat (CPWwS and COWwS) than in other rotations. Thus, smaller root systems at anthesis in soybean following winter wheat were associated with higher grain yield at maturity.
