Nitrogen Uptake by Two Plants in Response to Plant Competition as Regulated by Neighbor Density

NITROGEN UPTAKE by AQUATIC PLANTS

Ammonium Preference: Agrostis canina (velvet bentgrass) Amphibolis antarctica (a seagrass) Callitriche hamulata (a water starwort) Ceratophyllum demersum (hornwort) Cymodocea rotundata (a seagrass) Drepanocladus fluitans (an aquatic moss) Eichhornia crassipes (water hyacinth) Elodea densa (Anacharis) Elodea nuttallii (Western waterweed) Fontinalis antipyretica (willow moss) Halodule uninervis (...

Uptake of organic nitrogen by plants.

Languishing for many years in the shadow of plant inorganic nitrogen (N) nutrition research, studies of organic N uptake have attracted increased attention during the last decade. The capacity of plants to acquire organic N, demonstrated in laboratory and field settings, has thereby been well established. Even so, the ecological significance of organic N uptake for plant N nutrition is still a ...

Legume Growth and Nitrogen Fixation as Affected by Plant Competition for Light and for Soil Nitrogen'

395 ABSTRACT Since the legume responses to environmental factors may be different in grass mixtures than in pure stands, a pot experiment was conducted to evaluate the effects of plant top and root competition on the growth and N fixation of Desmodium intortum, cv. ‘Greenleaf’ grown in association with Setaria anceps, cv. 'Nandi' The plants were grown in deep, narrow pots which provided for ± t...

Yield and nitrogen uptake of soybeans and safflower plants grown on alkaline soil as affected by iron chelate, CCC and nitrogen

N uptake and yield of wheat as influenced by integrated use of organic and mineral nitrogen

The effect of integrated use of mineral and organic N sources (farmyard manure, poultry manure, and Filter Cake) on yield and N uptake of wheat were assessed in biennial field experiment carried out on silty clay loam soil in Nuclear Institute for Food and Agriculture, Tarnab, Peshawar Pakistan during 2005-07. Combined dose of N provided from all sources was applied @120 kg ha-1. There were 17 ...
