The gap between current average global wheat yields and that achievable through best agronomic management and crop genetics is large. This is notable in intensive wheat rotations which are widely used. Expectations are that this gap can be reduced by manipulating soil processes, especially those that involve microbial ecology. Cross-year analysis of the soil microbiome in an intensive wheat cro...

Soil microorganisms have important influences on plant growth and health. In this study, four black pepper fields consecutively monocultured for 12, 18, 28 and 38 years were selected for investigating the effect of planting age on rhizosphere and non-rhizosphere soil microbial communities and soil physicochemical properties. The results revealed that the relative abundance of the dominant bacte...

Reconstructing prairie habitat is one of the most promising techniques for conserving the imperiled prairie ecosystem and its associated organisms. However, the degree to which reconstructed prairies function like remnant prairies has not been fully examined. We evaluated the eVect of restoration planting prescriptions, as well as vegetative quality on butterXy communities inhabiting prairie re...

in order to investigate the possibility of reducing herbicide usage in combination with plant density and planting pattern, a field experiment was designed in chenaran, khorasan razavi, on 2010. the experiment was split plot treatments based on rcbd with three replications in factorial arragement. the treatments included of 3 level of plant density (100000, 120000 and 140000 plants ha-1) and 2 ...

One of the main environmental threats in the tropics is selective logging, which has degraded large areas of forest. In southeast Asia, enrichment planting with seedlings of the dominant group of dipterocarp tree species aims to accelerate restoration of forest structure and functioning. The role of tree diversity in forest restoration is still unclear, but the 'insurance hypothesis' predicts t...

Rapid establishment of closed canopy cover is a key goal in land reclamation. While re-establishment understory vegetation likely to positively contribute this goal, native herbaceous species are not typically planted on reclaimed sites though it an alternative reliance natural regeneration. The objective the present study was test principle hitchhiker production tree with recently industrial a...

Ricinus communis displays a broad range of phenotypic diversity in size, with dwarf, common, and large-sized varieties. To better understand the differences in plant productivity between a high-stalk variety and a dwarf variety under normal growth conditions, we carried out a comparative proteomic study between Zhebi 100 (a high stalk variety) and Zhebi 26 (a dwarf variety) combined with agrono...

The phyllosphere is colonized by a wide variety of bacteria and fungi; it harbors epiphytes, as well as plant-pathogenic bacteria and even human pathogens. However, little is known about how the bacterial community composition on leafy greens develops over time. The bacterial community of the leafy-green phyllosphere obtained from two plantings of rocket salad (Diplotaxis tenuifolia) and three ...

Long-term, multi-decade research on planted tree survival in urban settings is sparse. One understudied environment highway rights-of-way (ROW), lands adjacent to high-speed, unsignalized roadways. We conducted a re-inventory of planting cohorts northern Illinois, U.S. 48 km-long near Chicago which were 10-, 21-, and 30-years old evaluate long-term patterns diversity. Using each randomly select...
