METHOD OF DETERMINING PRODUCTIVITY OF PHOTOSYNTHETIC POTENTIAL OF SOYBEAN VARIETIES Russian patent published in 2015 - IPC A01G7/00 A01H1/04 

FIELD: agriculture.

SUBSTANCE: method comprises sampling, determining of leaf area, biometric indices by determining the number and weight of individual organs of the plant on phases of growth and development, recording of accumulation of vegetative mass of the whole plant and seeds during the period of development, the photosynthetic potential. The photosynthetic potential productivity index is calculated by the expression $$PPP=\frac{BP}{PP},$$ where BP is biological seed yield from 1 hectare; PP is photosynthetic potential generated for the whole growing season per 1 hectare of crops.

EFFECT: method enables to determine the amount of accumulation of organic matter in vegetative and reproductive organs.
