Analysis of Phytomass Yield in Wheat
Agronomy Journal, 1992AbstractGrain yield (GRY) increases in wheat (Triticum aestivum L.) have been achieved through increases in harvest index (HI). Further improvements in HI appear difficult so further increases in GRY may have to come through increases in phytomass yield (PMY). Increases in PMY also should increase yield of nongrain plant parts (NGRY) which is important

Comparing nondestructive measures of forage structure and phytomass
Canadian Journal of Plant Science, 2000Nondestructive radiative transfer and canopy volume methods were compared with the destructive hand-clipping method to determine forage structure and phytomass. On a native range site, fifteen 1-m2 circular plots were located at each of five microsites. On a crested wheatgrass site, thirty 1-m2 plots were located in grazed and in ungrazed areas.

Phytomass, Seasonal Phenology and Photosynthetic Studies
1982The ultimate objective of the projects concerned with plant growth is the measurement of net primary production (NPP), ie that part of the total or gross primary productivity (GPP) of the photosynthetic plants remaining after the photosynthate has been utilized in respiration of these plants.

Seasonal Dynamics of Phytomass and Nutrients in Chalk Grassland
Oikos, 1989Effects of extra N input on above- and below-ground phytomass and on the concentration of N and P in chalk grassland during one growing season were studied, with special attention to the effects on the grass Brachypodium pinnatum compared with other species. N fertilization in spring resulted in a significantly increased peak standing crop. This higher

Trophic Exploitation and Arctic Phytomass Patterns
The American Naturalist, 1983Aboveground phytomasses of tundra communities and changes in moss phytomass after a lemming peak were reviewed to test the prediction of the hypothesis of exploitation ecosystems that herbivory limits the aboveground phytomasses of moderately unproductive plant communities.

The heat exchanger of small pellet boiler for phytomass
AIP Conference Proceedings, 2014Combustion of pellets from plant biomass (phytomass) causes various troubles. Main problem is slagging ash because of low melting temperature of ash from phytomass. This problem is possible to solve either improving energetic properties of phytomass by additives or modification of boiler construction.

Benefits of additives application during combustion of phytomass
AIP Conference Proceedings, 2016Phytomass, particularly wheat straw as a source of energy has countless benefits, but it has many problems in its direct burn too. The worst problem is the ash flow temperature. The aim of study was to analyze and reduce the problems of the wheat straw combustion. The experiment was conducted under realistic conditions.

Management effect on phytomass and litter in seminatural grasslands
2007Nowadays, not only in Italy but also in Central and Eastern Europe, the reduced level of pastoral activity is a remarkable problem in maintaining the landscape biodiversity. The abandonment of the pastures causes deep modifications in natural herbaceous vegetation and the consequent formation of vegetal association characterized by oligotrophic species.
