  2. Ethanol fuel energy balance - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fuel_energy_balance

    In Brazil where sugar cane is used, the yield is higher, and conversion to ethanol is more energy efficient than corn. Recent developments with cellulosic ethanol production may improve yields even further. [12] In 2006 a study from the University of Minnesota found that corn-grain ethanol produced 1.25 units of energy per unit put in. [13]

  3. Available water capacity - Wikipedia

    en.wikipedia.org/wiki/Available_water_capacity

    It is also known as available water content (AWC), profile available water (PAW) [2] or total available water (TAW). The concept, put forward by Frank Veihmeyer and Arthur Hendrickson, [ 3 ] assumed that the water readily available to plants is the difference between the soil water content at field capacity ( θ fc ) and permanent wilting point ...

  4. Saccharum sinense - Wikipedia

    en.wikipedia.org/wiki/Saccharum_sinense

    The second domestication center of sugarcane is India, Indo China , southern China and Taiwan where S. sinense was a primary cultigen of the Austronesian peoples. Words for sugarcane exist in the Proto-Austronesian languages in Taiwan, reconstructed as *təbuS or **CebuS, which became *tebuh in Proto-Malayo-Polynesian.

  5. Plant growth analysis - Wikipedia

    en.wikipedia.org/wiki/Plant_growth_analysis

    Agronomic studies often focus on the above-ground part of plant biomass, and consider crop growth rates rather than individual plant growth rates. Nonetheless there is a strong corollary between the two approaches. More specifically, the ULR as discussed above shows up in crop growth analysis as well, as: = . = .

  6. Saccharum officinarum - Wikipedia

    en.wikipedia.org/wiki/Saccharum_officinarum

    Saccharum officinarum, a perennial plant, grows in clumps consisting of a number of strong unbranched stems. A network of rhizomes forms under the soil which sends up secondary shoots near the parent plant. The stems vary in colour, being green, pinkish, or purple and can reach 5 metres (16 feet) in height.

  7. Growing degree-day - Wikipedia

    en.wikipedia.org/wiki/Growing_degree-day

    Growing degrees (GDs) is defined as the number of temperature degrees above a certain threshold base temperature, which varies among crop species. The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.

  8. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    The simpler C3 cycle which operates in most plants is adapted to wetter darker environments, such as many northern latitudes. [citation needed] Maize, sugar cane, and sorghum are C4 plants. These plants are economically important in part because of their relatively high photosynthetic efficiencies compared to many other crops. Pineapple is a ...

  9. Sugarcane - Wikipedia

    en.wikipedia.org/wiki/Sugarcane

    Sugarcane or sugar cane is a species of tall, perennial grass (in the genus Saccharum, tribe Andropogoneae) that is used for sugar production. The plants are 2–6 m (6–20 ft) tall with stout, jointed, fibrous stalks that are rich in sucrose , [ 1 ] which accumulates in the stalk internodes .
