Restoration of wet prairie in the central midwestern United States should include Prairie cordgrass (Spartina pectinata), but historic densities of this once dominant species are not easily achieved. Spartina pectinata was transplanted into a former agricultural field in three planting strategies: 20 small plugs, 4 medium-sized plugs, and a single large plug, with each treatment area totaling 0...
Pre-planting factors have been associated with the late-season severity of Stagonospora nodorum blotch (SNB), caused by the fungal pathogen Parastagonospora nodorum, in winter wheat (Triticum aestivum). The relative importance of these factors in the risk of SNB has not been determined and this knowledge can facilitate disease management decisions prior to planting of the wheat crop. In this st...
Modelling crop evapotranspiration (ET) response to different planting scenarios in an irrigation district plays a significant role in optimizing crop planting patterns, resolving agricultural water scarcity and facilitating the sustainable use of water resources. In this study, the SWAT model was improved by transforming the evapotranspiration module. Then, the improved model was applied in Qin...
This research was conducted in 2007 and 2008 cropping seasons in the experimental field of Shahid Salemi, Ahvaz, south west of Iran. In each year, the study consisted of a split split-plot experiment, using Randomized Complete Block Design (RCBD) with three replications. Four irrigation levels including irrigationoff at the 8 leaf, the 12 leaf and the tasseling stages and optimum irrigation wer...
Plants have an important impact on soil microbial communities and their functions. However, how plants determine the microbial composition and network interactions is still poorly understood. During a four-year field experiment, we investigated the functional gene composition of three types of soils (Phaeozem, Cambisols and Acrisol) under maize planting and bare fallow regimes located in cold t...
The rice water weevil, Lissorhoptrus oryzophilus, is the most destructive insect pest of rice in the United States. Early planting of rice to avoid damaging infestations of the rice water weevil has long been suggested as a management tactic. A five-year study was conducted to characterize the influence of rice planting date on rice water weevil management in light of recent trends toward earli...
Camelina is one of the plants that it seed yield is highly dependent on planting date. This experiment was conducted using randomized complete blocks design with three replications in research farm of Fasa Branch, Islamic Azad University, Fasa, Iran in 2018 and 2019 cropping seasons. Planting dates at six levels; November 1, 11, 21 (autumn sowing) and February 20, March 1 and 11 (winter sowing)...
Agroforestry interventions may act as catalysts for ecosystem service development and changes in supply therefore rehabilitate degraded land. This study investigates the trajectories of services coffee systems with a different time since transition to agroforestry Colombia, interactions among services, biotic abiotic factors that explain them. Therefore, we chronosequence farms, 1–40 years plan...
