With almost eight billion people on earth, the demand for aquatic food is increasing. Aquaculture production is projected to rise from 40 million Metric Tons by 2008 to 82 million Metric Tons in 2050. Moreover, the expansion of aquaculture is also restricted due to land costs and by its strong dependence on fishmeal and fish oil. Additionally, environmental degradation and pollution have been ...
With around 50-80 dry tonnes of biomass yield per hectare every year, Arundo donax (giant reed) is way ahead of its competitors. Of course, this yield depends on climate and applied agricultural technology. In this article below, the studies carried out concerning the biomass yield and economics of Arundo donax ...
Res. 12(3), 46-51, March 2018. To investigate the maize yield and nutrient concentration in its leaves as affected by biochar from different organic materials (wheat straw and sugarcane bagasse), a field experiment was conducted on maize crop during 2013 at koont research farm chakwal. ...
On average Hibrix increased the pasture biomass yield by 34% across the farm. The protein content and metabolisable Energy (Mj/kg Dm) were significantly higher in the Hibrix ...
Still, millions of small-scale farmers, especially in Latin America and Africa, are turning to it because it’s low-cost and low-tech, and it produces far greater yields than conventional agriculture while using far less land and water. ...

Department of Energy (DOE), announced $15 million in funding for three projects that will work to improve algal biomass yields to reduce production costs of algae-based biofuels and bioproducts. ...
On January 15, 2016, the U.S. Department of Energy (DOE) announced up to $15 million in funding for the development of algal biofuel intermediate technologies. Technology applicants should be likely to produce 3,700 gallons of algal biofuel intermediate per acre per year on an annualized average basis in an outdoor test environment by 2020. Applicants should also address a topic area within the ...
Carbonate and phosphate precipitation in the sea-water media was prevented by maintaining a low concentration of phosphate and by controlling the pH in the range of 8.0–8.3. The mean annual yield of biomass on sea-water plus urea as nitrogen source was 7.35 g (dry weight) m-2· day-1, a value slightly lower than that obtained on the standard ...
The investigation revealed that the yield of biomass in de-calcified inland saline water was comparable to the yield obtained in synthetic chemical-based prescribed growth medium. Further, the quality of biomass in terms of protein, chlorophyll a, carotenoids and phycocyanin contents was also comparable to the prescribed medium. ...
Multi-year field experimental data from 2004 and 2011 were used to calibrate and validate the model for simulating biomass, canopy cover (CC), soil water content, and grain yield under rainfed conditions. ...
FA application increased the number of leaves, plant height, biomass and yield of three crop plants (palak, mung bean and chilli) and recorded maximum in F25 treatment (25% FA–amended soil). Application of more than 25% results in decline in growth and yields of plants.Keywords: fly ash, amendment, plant growth, crop yield, ...
The removal of cadmium and chromium, at comparable initial molar concentration (1, 2, 4 mM) has been studied employing progressively increasing concentrations of S. platensis dry biomass. The highest yield of Cd removal (≥98%) was obtained with 2 g l−1 of this biosorbent, whereas no more than 77.5% of Cr was removed with 4 g l−1 biomass. ...
As corn planting dates were delayed, greater amounts of vetch mulch and lower weed density helped reduce weed biomass. Corn yields in the organic no-till system with a hairy vetch cover crop ranged from 1.1 Mg ha–1 to 9.6 Mg ha–1. Low yields were attributed to incomplete control of hairy vetch, weed competition, reduced corn plant populations, ...
This 2-yr field study in Mississippi evaluated the effect of N (0, 80, and 160 kg/ha), growth stage (bud formation and flowering), and harvest time or cut (first cut in mid-July, second cut beginning of October) on peppermint yields, oil content, and composition. Biomass and oil yields were higher from the first cut than from the second. Overall, ...
Crop water use was greatest with the most frequent irrigation treatment (35% depletion all season) (1067 mm), while the 50 and 65% depletion treatments (all season) were not different (882 and 844 mm, respectively). Despite increased biomass at the V-17 and anthesis stages, no differences due to irrigation frequency were found at harvest for yield of ...
The use of maize (Zea mays L.) stover as a feedstock for cellulosic biofuels production will create demand for maize hybrids with greater stover yield. It is expected that grain yield will remain the most critical trait and continue to drive hybrid sales, requiring that any increases in stover yield be made without sacrificing grain ...
Ferulate cross-linking of lignin to arabinoxylan contributes to poor cell wall degradability of grass forages. We hypothesized that reduced ferulate ester deposition will result in formation of fewer ferulate cross links and improved degradability. Objectives were to determine if the putative seedling ferulate ester (sfe) maize (Zea mays L.) mutant, selected for reduced ferulate esters in ...
For bermudagrass, flaccidgrass, and lovegrass, the greatest biomass yield year–1 was produced from plots harvested twice year–1. Switchgrass produced significantly more biomass than the other three species. Biomass yield to N response functions were estimated for switchgrass. For most biomass ...
The OPT and traditional farming practice (TRA) treatments both gave higher average grain yields than zero-N controls (CK). Rice yields were considerably smaller in Rw than Ro under CK. Compared with TRA, OPT led to significantly higher aboveground N uptake, biomass accumulation, and grain yield in Rw. Over the 2 yr of the study, ...
Increased biomass productivity could be achieved through double-cropping if extended growth duration could be realized with minimal reductions in growth efficiency relative to sole-cropping. To test this hypothesis, functional growth analysis was used to assess the relative importance of photosynthetic duration and efficiency in determining biomass production by ...
