To calculate total water volume (m3) required per metric ton of crop production (TWV), the following equation was used: {text{TWV = [CY}} times ({text{metric ton/1,000 kg}}) ]^{ - 1} (4)Using this equation, the units of crop yield were converted from kg/1,000 m3 to m3/metric ton.
Continuous RR is per one unit change of crop density.
Prior to deploying INGARD®, it was established that some crops produced more Helicoverpa moths per unit area of crop than others (Baker et al. 2008).
"Full irrigation" treatments achieved the highest yield, quality, and profitability per unit of the cropped area, while ORDI increased the water productivity and reached the highest profitability per unit of volume of irrigation water supplied to the crop (average up to 12.26 €m−33 for the "0.6 ORDI" treatment vs. 8.38 €m−33 for the "full irrigation").
These results were derived by taking the direct energy requirements (per unit of the different crop and animal enterprises), multiplying these by the observed crop production areas and livestock numbers and aggregating to the national level [50].
An independent crop-raiding incident was used as the basic unit of measurement, whereby crop-raiding by an individual orangutan on the same farm, on the same day, was classified as a single event, irrespective of whether it raided more than once.
While in absolute terms, higher per capita agricultural income levels are found in frontiers where largeholders predominate, the corresponding incomes are higher in smallholder frontiers when prorated by unit of land under crops and pasture.
The addition of extra P in the soil led to consume more resources for the crop production, and hence, the costs of production of crop plants per unit area increase (Aziz et al. 2006).
Most importantly, we found differences between East and West Germany in terms of input/output efficiency, particularly the amount of crop harvest per unit of nitrogen inputs (i.e., nitrogen productivity, Fig. 6g) or the amount of harvest per agricultural worker (agricultural labor efficiency, Fig. 6h).
