Influence of fertilizers upon photosynthetic potential and productivity of winter rye

Abstract

Purpose. To study the influence of species, norms and terms of fertilization on the formation of photosynthetic potential and yield of winter rye. Methods. Field, mathematical and statistical. Results The largest photosynthetic potential was for the retail supply of nitrogen fertilizers - 4.54 - 5.10 million m2 / ha / day, or 46-64% higher than control (3.11 million m2 / ha / day). Conclusions It has been established that winter rye forms a high area of the leaf surface, which increases significantly for improving the mineral nutrition of plants.
