“…practices (Griffith et al, 1988;Lund et al, 1993;AdvientoBorbe et al, 2007). Most previous studies on rotation effect were conducted on research stations or on-farm field trials conducted for a limited number of site-years, where crops were managed following "recommended" or "best" farm management practices.…”

“…The SPC1 and SPC2 are biophysical indicators of field-to-field variability and WPC1 and WPC2 are indicators of years' weather variability; hence, we decided to use these factors in the model instead of field and year as individual factors and, similarly, their interactions with crop sequence were included. For example, rotation effect on yield can be amplified in no-tilled maize fields, with heavy residue from prior high-yield maize crop, due to sowing and emergence delays, especially in years with earlyseason low temperature and high precipitation (Lund et al, 1993). Likewise, applied N fertilizer was also included in the model because maize grown in rotation with soybean typically receives less amount of N fertilizer compared with applied N fertilizer to maize grown after maize (Gentry et al, 2001).…”

Cereal yields tend to be higher in cereal–legume rotations relative to cereal monoculture yields. We investigated the influence of crop rotation on yield and input‐use efficiency in high‐yield irrigated maize (Zea mays L.)‐based cropping systems using producer‐reported data from western U.S. Corn Belt (about 11,000 observations). Across regions, average yield of maize grown after soybean [Glycine max (L.) Merr.] (S–M) was 0.2 to 0.6 Mg ha−1 (2–5%) higher, relative to yield of maize grown after maize (M–M). Soybean yield was 5% greater after two consecutive maize crops (M–M–S) than after only 1 yr of maize (S–M–S). Nitrogen fertilizer rate in maize fields was 13 kg N ha−1 (6%) lower in S–M than M–M fields, which, together with higher maize yields in S–M fields, resulted in 11% higher nitrogen partial factor productivity (PFPN). Difference in PFPN was unrelated with residual soil N–NO3− from prior crop. Analysis of rotation data indicated that rotation effect persists across a wide range of maize yields, from 6 to 15 Mg ha−1, though magnitude of rotation effect decreases with increasing yield level. Trends toward greater proportion of total maize area in S–M, rather than M–M, accounts for 8% of maize yield gain in U.S. Corn Belt since 1970. Similarity between our findings and previous research highlights the opportunity to quantify impact of management on yield and efficiencies by using producer data as a complement to high‐cost multi‐year, multi‐site field experiments.Core Ideas We assessed rotation effect on on‐farm yield and input‐use efficiency. Analysis was based on a large producer‐reported database collected from high‐yield irrigated maize–soybean systems. There was a consistent positive rotation effect on yield and partial factor productivity for N fertilizer. Number of previous maize crops did not affect maize yield in monoculture but soybean yields were higher following multiple maize crops. Increasing maize area in rotation relative to monoculture accounts for 8% of the maize yield gain in the U.S. Corn Belt since 1970.

“…While the positive impacts of NT for environmental health through C sequestration, improving soil biological activity, soil structure, and soil water conservation were frequently reported (Hobbs et al, 2008;Six et al, 2002, FAO, 2011, Busari et al, 2015, the short-and long-term yield benefi ts from NT and CT have been mixed, that is, both, better yield from NT compared with CT (Endale et al, 2008;Toliver et al, 2012;Farooq et al, 2011) and better yield from CT compared with NT were reported (Davidson and Santelmann, 1973;Lund, 1993;MacHado et al, 2007). Perhaps that has contributed to slower adoption of NT technologies.…”

Core Ideas Average sorghum yield advantage was 120% for no tillage over conventional tillage and 55% for reduced tillage over conventional tillage.Average wheat yield advantage was 31% for no tillage over conventional tillage and 12% for reduced tillage over conventional tillage.Available soil water at planting in soil profile was less for conventional tillage than both no tillage and reduced tillage for both crops.There was a decline in wheat yield over time due to increased seasonal temperature. Tillage is among crop management factors that affect yield, profitability, and environmental quality. The objective of our study was to evaluate the effect of three long‐term tillage intensities; conventional tillage (CT), reduced tillage (RT), and no‐till (NT), on winter wheat (Triticum aestivum L.) and grain sorghum (Sorghum bicolor L.) yield, available soil water (ASW), and water productivity. The study was conducted near Tribune, KS, from 1991 through 2015 in a wheat–sorghum–fallow (WSF) rotation. The CT plots were tilled (primarily with a sweep plow), on average, four to five times per fallow season; NT plots used herbicides for weed control during fallow. The RT plots used a combination of herbicides and tillage for weed control during fallow prior to both crops for years 1991 to 2000; and, for the years 2001 to 2015, the RT system was NT before sorghum planting (short‐term NT) and CT before wheat planting. On average, there was a 31% wheat yield advantage for NT over CT, 16% NT over RT, and 12% RT over CT. On average, there was a 120% sorghum yield advantage for NT over CT, 41% NT over RT, and 55% RT over CT. Sorghum yields were 80% greater for continuous NT compared with short‐term NT (2001–2015 RT). The average of profile ASW at planting was less for CT compared with NT and RT. There was a significant yield and water productivity benefit in the order NT > RT > CT for both crops, but greater for sorghum than wheat.

“…Previous studies have shown that, for various reasons, continuous soybean cultivation involves significant yield decrease in the long-term (Crookston et al, 1991;Kelley et al, 2003;Meese et al, 1991), has negative effects on soil water balance (SaladoNavarro and Sinclair, 2009), influences soil chemical properties, and increases disease pathogens. However, the benefits of crop rotation depend on which crops are included in the rotation, and in which sequence (Lund et al, 1993). Unfortunately, it has been impossible to obtain detailed information about the precise number of rotation sequences and schemes which have been used over years.…”

Avertissement :Les commentaires et analyses développés n'engagent que leurs auteurs qui restent seuls responsables des erreurs et insuffisances. AbstractIn the context of the rapid development of the cultivation of genetically modified soybeans in Argentina, we conduct a hedonic analysis of agricultural land values. The main objective is to evaluate the impact of land tenure systems and agricultural practices on these values. Data on 338 parcels, located in the Pampas region, are analyzed. The tenure appears to be a particularly important variable. We find that plots rented either by physical persons or by companies are negatively valued in relation to plots owned. Results also highlight the importance, though not to a large degree, of a diversified cropping pattern compared to soybean monoculture. Soil quality, location of the plots, distance to markets, as well as to the nearest city, were also found to affect land values.
