[Remote assay for chlorophyll photosynthetic potential of crops on the example of wheat].
An optical remote assay for biological production of crops in the field during the vegetation period is proposed. Our calculations demonstrate a good correlation between the S(t) value and crop yield (in the range from 0.85 to 0.90); the higher is S(t) for the vegetation period, the higher is the crop yield. S(t) value can be used to calculate the increase in dry and wet biomass for various crops during the whole vegetation period with an error of less than 10-12%. The absolute error of crop yield for 110 cultivars of wheat, oats, and barley during the experimental period was +/-3-3.5 quintal/ha with the mean crop yield of 14-38 quintal/ha.
