STUDY OF DEFOLIATION INTENSITY AND NITROGEN RATE EFFECTS ON YIELD, YIELD COMPONENTS AND GERMINATION TRAITS OF PRODUCED SEED IN WHEAT (Triticum aestivum)

Agricultura, 2013
A field experiment and a laboratory experiment were conducted in 2011-2012 to determine the effect of defoliation intensity and nitrogen rate on yield, yield components and seed germination of wheat (Triticum aestivum).

Intermediate coupling between aboveground and belowground biomass maximises the persistence of grasslands [PDF]

, 2012
Aboveground and belowground biomass compartments of vegetation fulfil different functions and they are coupled by complex interactions. These compartments exchange water, carbon and nutrients and the belowground biomass compartment has the capacity to ...

Leaf tissue flows and defoliation patterns of Alexandergrass grazed by heifers receiving energy supplement

Acta Scientiarum: Animal Sciences, 2019
The study was carried out to evaluate defoliation patterns and to quantify leaf tissue flows in Alexandergrass (Urochloa plantaginea (Link.) Hitch) grazed by beef heifers receiving whole rice bran in three levels of supplementation (0, 0.5 and 1 % of ...

Interactive effect of herbivory and competition on the invasive plant Mikania micrantha. [PDF]

PLoS ONE, 2013
A considerable number of host-specific biological control agents fail to control invasive plants in the field, and exploring the mechanism underlying this phenomenon is important and helpful for the management of invasive plants.

Quantifying the interactions between defoliation interval, defoliation intensity and nitrogen fertiliser application on the nutritive value of rainfed and irrigated perennial ryegrass

, 2017
A key goal of temperate pasture management is to optimise nutritive value and production. The influence of individual components such as irrigation, nitrogen (N) fertiliser, and grazing interval and intensity has been well researched, yet conjecture ...

Bromus-Poa response to defoliation intensity and frequency under three soil moisture levels

, 2002
Smooth brome (Bromus inermis Leyss.) and Kentucky bluegrass (Poa pratensis L.) are important herbage for livestock and wildlife in Aspen-Boreal ecosystems in central Alberta, but there is paucity of information on the relationship between soil moisture ...

Effects of Defoliation at Different Fertility Stages on Material Accumulation, Physiological Indices and Yield of Cotton

Agriculture
In recent years, severe hailstorms have caused damage to cotton leaves and stalks. In order to identify the effects of cotton leaf damage on its dry matter accumulation, protective enzyme activity and yield in different periods, in this experiment ...

Effect of Post-grazing Sward Height on Ingestive Behavior, Dry Matter Intake, and Milk Production of Holstein Dairy Cows

Frontiers in Animal Science, 2021
Sward height is strongly related to the daily dry matter intake of grazing dairy cows, which consequently determines animal performance. Despite that, few studies have explored the potential to increase milk production by managing post-grazing sward ...

Synergistic effects of maize defoliation and common bean relay cropping in Western Ethiopia

JSFA reports, EarlyView.
Abstract Background Maize defoliation is practiced to enhance crop management by improving light penetration, nutrient allocation, controlling weeds, and providing supplementary feeds for livestock. A rapid decline in soil fertility and low crop yields associated with maize‐based monocropping has prompted the recent introduction of maize common bean ...
