COMPARISONS OF PLANT PRODUCTIVITY
Biological Reviews, 1963Summary1. This article discusses the principles of comparative productivity and the net primary productivity of different types of plant community.2. Primary production is denned as the weight of new organic matter created by photosynthesis over a period; expressed as a rate it becomes productivity.

Selective adsorption of plant products
Biotechnology and Bioengineering, 1988AbstractThe results from this study demonstrate that neutral resins can selectively concentrate specific indole alkaloids from dilute aqueous mixtures. Adsorption was observed to provide a one to two order of magnitude improvement in concentrating these alkaloids, as compared to an equivalent single‐staged extraction. Since the sorption correlates with

The Theoretical Limit to Plant Productivity
Environmental Science & Technology, 2014Human population and economic growth are accelerating the demand for plant biomass to provide food, fuel, and fiber. The annual increment of biomass to meet these needs is quantified as net primary production (NPP). Here we show that an underlying assumption in some current models may lead to underestimates of the potential production from managed ...

Human excreta for plant production
Bioresource Technology, 2005Human excreta are a natural resource which is always available in all societies. Unfortunately, their value is highly underestimated in present agriculture and horticulture including in many tropical developing countries. Especially human urine is rich in nitrogen. This "free" fertiliser should be used as much as possible and needed.

PHOtOsyntHESiS and PLant ProDuctivity
Chemical & Engineering News Archive, 1979The increasing food demands of the world's growing population will require increases in agricultural yields averaging about 2.5% a year over the next 25 years, to double primary food production, ac...

Journal of Theoretical Biology, 1985
Of the factors limiting plant growth some are more fundamental than others in the sense that they are not easily or not at all available for manipulations either by the plant itself or by man. Among these are physical limitations like incoming solar radiation and evolutionary ones like basic biochemical functions, whereas e.g.

The UK currently produces and imports a great variety of pot plants and cut flowers, so that the consumer can be offered a non-stop supply. Many of these plants are seasonal, for example, Cyclamen (pot plant) is primarily grown for the Christmas market, while others are produced All Year Round (AYR), for example, chrysanthemums (cut flower or pot plant)

Inhibition of Herbicide Photodegradation by Plant Products
Journal of Agricultural and Food Chemistry, 2011Pesticide reactivity toward light is rarely considered at the leaf surface after crop treatment; regardless, these degradation reactions directly impact the pesticide effectiveness. The use of sunscreen adjuvants to overcome photodegradation has presented some limitations so far.

Ornamental Plant Production in Croatia
Acta horticulturae et regiotecturae, 2008It is obvious that the ornamental plant production in Croatia is insufficient to meet the domestic demand, not to mention the exports. What is the reason for this situation, why is a country with such exceptionally suitable climate (especially significant for production in open field) and laws harmonised with EU regulative so backward in this branch of
