PHOTOSYNTHETIC APPARATUS AND PRODUCTIVITY OF AMARANTH C4 OF GROUP OF PLANTS
The experiments for establishing of influencing on the main elements of mineral or organomineral feeding on the productivity of amaranth on changing of different parameters of photosynthetic apparatus: the area of leaves the content of chlorophyll «a» и «b» in the leaves, the amount of chloroplasts in the cells of leaves, the intensity of photosynthesis and pure productivity of photosynthesis are set. It is stated that when we add into the soil nitrogen, phosphorus and potassium 90 kg of acting matter (substance) per hectare of seeding, the amount of green biomasses is increaser while adding into the soil of mineral (N45P65K30) fertilizers with organic 20t/hectare the harvest of biomasses is increasing more higher and reaches 1673 centner /hectare, seeds – up to 22,4 centner /hectare. This is reached by improving the activity of work of aboved inumerated sample of amaranth.
