Managing grasslands for forage and ground-nesting bird habitat requires appropriate defoliation strategies. Subsequent early-summer species composition in mixed stands of native warm-season grasses (Indiangrass (IG, Sorghastrum nutans), big bluestem (BB, Andropogon gerardii) and little bluestem (LB, Schizachyrium scoparium)) responding to harvest intervals (treatments, 30, 40, 60, 90 or 120 d) ...

The valid confirmation of a positive change (improvement) in a patient's health status due to intervention has been at the core of medicine and rehabilitation since their very inception as clinicians always aspired to ensure that treating their patients had led to successful outcomes both in acute and chronic conditions. However what is change: either improvement or worsening (aggravation), is ...

The pathogenicity of two populations of the northern root-knot nematode, Meloidogyne hapla Chitwood, population 1 (P1) from alfalfa and population 2 (P2) from sainfoin, was studied on both alfalfa and sainfoin for 25 weeks. Alfalfa and sainfoin plants inoculated with P2 had significantly (P </= 0.05) higher mortality than plants inoculated with P1. Plant stands over all weeks for the uninoculat...

Pink-pigmented facultative methylotrophic bacteria (PPFMs) are associated with the roots, leaves and seeds of most terrestrial plants and utilize volatile C(1) compounds such as methanol generated by growing plants during cell division. PPFMs have been well studied in agricultural systems due to their importance in crop seed germination, yield, pathogen resistance and drought stress tolerance. ...

The community managed conservation area forest (AKKM) of Kampung Sawesuma is part the lowland landscape Northern Papua. Lowland forests have a very high diversity plant species and act as carbon sinks stored in tree stands. To determine amount stands, an estimation density stands was carried out AKKM Sawesuma, Jayapura. Estimation by non-destructive method using sample plots (measurement transe...

[1] The Leaf Area Index (LAI) and its spatial distribution are key features to describe the forest ecophysiological processes. A stable and reproducible relationship is obtained between the LAI and the standard deviation sNDVI of the pixel-based satellite-derived normalized difference vegetation indices (NDVI) of forest stands. In situ measurements of LAI have been performed with the LAI-2000 P...

in order to investigation of nitrogen fertilizer split application effect on quantity yield and grain quality of rice varieties, an experiment was carried out based on rcbd design as split plot experiment in three replications in langroud in 2006. mainand sub factor were variety (hashemi and bahar 1) and five nitrogen fertilizer split application (split of 150 kg.ha-1 n at transplanting, stemmi...
