Biomass Production and Hydrological/Water Quality Impacts of Perennial Crop Production on Marginal Land

Qingyu Feng Purdue e-Pubs (Purdue University System) 2013

Other claims from this paper (13)

Observation The watershed contains 641 km2 of marginal land, 23% of its area.
Observation Converting all marginal land to switchgrass could produce 45 million gallons of bioethanol.
Observation Converting all marginal land to Miscanthus could produce 57 million gallons of bioethanol.
Observation Switchgrass production would not support the assumed 50 million gallon biorefinery.
Observation Miscanthus production could support the assumed 50 million gallon biorefinery.
Intervention effect Conversion to the two crops significantly affected hydrology and water quality at marginal land scale.
Observation At watershed scale, the hydrologic and water quality impact could be insignificant.
Association Switchgrass has greater total ET loss than Miscanthus because of non-growing-season evaporation.
Intervention effect Soil erosion would fall under switchgrass and Miscanthus conversion.
Intervention effect Mineral and organic nitrogen and phosphorus would fall with reduced fertilization for biomass production.
Intervention effect Early-season nitrogen in surface and subsurface flow tended to rise following conversion of grass and forest land.
Association Miscanthus reduced soil erosion more than switchgrass.
Association Miscanthus reduced nutrient loss more than switchgrass.

Physiological Causes of Differences in Grain Yield between Varieties of Barley

D. J. WATSON; GILLIAN N. THORNE; S. A. W. FRENCH Annals of Botany 1958. doi:10.1093/oxfordjournals.aob.a083616

Other claims from this paper (19)

Association Proctor and Herta yielded 10—15 per cent more grain than Plumage-Archer without nitrogen fertilizer.
Intervention effect Nitrogen increased the varietal grain yield difference to about 30 per cent.
Intervention effect Higher nitrogen caused Plumage-Archer lodging without increasing its yield.
Observation Proctor and Herta remained standing under higher nitrogen.
Observation The three varieties had similar leaf-area index, net assimilation rate and total dry weight before ear emergence.
Association After ear emergence Herta had a smaller leaf-area index than Proctor and Plumage-Archer.
Observation Shaded-ear pot experiment found nearly equal dry matter contribution per leaf area across varieties.
Mechanism The authors attributed higher yield to photosynthesis by the ears.
Association In pots, Proctor and Herta yielded only about 6 per cent more than Plumage-Archer.
Association Field ear sizes were greater for Proctor and Herta than Plumage-Archer.
Association Ear dry weight at emergence was greater in the higher yielding varieties.
Observation Herta ears may have higher photosynthetic efficiency.
Association Plumage-Archer absorbed more potassium.
Association Herta absorbed less phosphorus than the other varieties.
Observation About a quarter of final nitrogen was absorbed after ear emergence.
Observation A third of phosphorus was absorbed after ear emergence.
Observation Potassium content was nearly maximal at ear emergence and later decreased.
Observation Ear photosynthesis contributed 26 per cent of grain dry matter, including 10 per cent from awns.
Observation Flag-leaf lamina, sheath and peduncle supplied 59 per cent of grain dry matter, and lower shoots supplied 15 per cent.

Other claims from this paper (4)

Intervention effect Permanent salinity greatly reduced biomass production and differentiation of reproductive organs in soybean, regardless of salinity level.
Intervention effect Soybean at 0.8S never reached the reproductive phase.
Intervention effect Soybean at 0.4P showed only small differences in growth data from the control.
Recommendation A leaf chloride concentration of 1 mg g-1 of Cl- in dry matter should be considered a maximum threshold for soybean yield.

Intervention effect Simazine applied at flowering decreased grain yield.
