In-situ rice residue retention along with weed biomass recycling (MT) for 4-years improved soil quality, reduced cost of production and stabilized productivity in a low-input marginal (marginal soil and small scale farmers) hill agriculture.
This provided an important means of reducing labor input and marginal labor costs through movements from overtime to short-time schedules.
Despite of that this plants are adapted to suboptimal environments that allows its production not compete with food production because it requires less energy input, bringing marginal lands into production with its all social-benefit consequences.
Additionally, an input's marginal product is the extra output that can be produced by using one more unit of the input, assuming that the quantities of no other inputs to production change.
Perennial grasses, such as miscanthus and switchgrass, have been proposed as key bioenergy crops in Europe and the US, based on their low input and marginal land requirements.
To test Nodal signaling maintenance after input removal, marginal cells of gfp-smad2/h2b-rfp or wild-type donor embryos at 30% epiboly were transplanted into the animal pole of stage-matched wild-type host embryos.
CAVIAR-Gene takes as input the marginal statistics for each variant at a locus, an LD matrix consisting of pairwise Pearson correlations computed between the genotypes of a pair of genetic variants, a partitioning of the set of variants in a locus into genes, and the kinship matrix which indicates the genetic similarity between each pair of individuals.
Beyond the expectation of high biomass yield with few inputs on marginal land, conversion quality standards for energy crops have yet to be defined by the biofuels industry.
The application of the biproportional adjustment algorithm here is similar to its application in the construction of an economic input-output matrix, as noted above: marginal input and output (row and column) totals are known precisely, but interindustry product flows the elements of the matrix are not.
Jorgenson and Kevin Stiroh (2000) constructed constant-quality indexes of capital and labor inputs, including investments in information technology equipment and software and college-educated workers by weighting the components of each input by their marginal products.
However, the annual green manure supply supported yields mostly at marginal input levels and was overridden by mineral fertilizers independent of the inclination.
