Croplands are highly variable both temporally and spatially. The feed intensity weighted livestock production (referred to as Livestock Production, L.P.), calculated as 0.3 (beef + mutton production) + 0.1 (milk production) + 1.0 (pork + poultry + egg production) was used for individual countries by Alexandratos (1995). The highest cropping intensity has been recorded in samba (212.63%) whereas lowest It may be measured by the formula-gross cropped area/net sown area x 100. Cropping intensity is defined as a ratio be­tween net sown area (NSA) and gross cropped area (GCA). Cropping intensity ( # of crops per year) Crop calendar (planting & harvesting dates) Inundation and paddy rice Temporal profile analysis of individual pixels . Yearly Cropping intensity = 75+ 50=120%. The map shows cropping intensity, which is the number of crop harvests per cell per year. 3. Total Cropped Area divided by Net Sown Area multiplied by 100%. The co-efficient of co-relation formulae according to Karl Pearson (1896) has been used to obtain the relationship Cropping intensity is defined as the number of crops a farmer grows in a given agricultural year on the same field (Raut et al., 2011), and is another means for intensification of production from the same plot of land.
