The influence of environmental factors and technological means on photosynthesis
best of all is reflected by plant net photosynthesis productivity, which is expressed by
the ratio of dry weight increase during certain time and leaf assimilation area during
the same period. Plant photosynthesis productivity in the early carrot growth period
(from sowing up to 6–10 leaves) on the average was 0.37 mg cm-2 in 24 h, crop
photosynthesis productivity – 30.0 mg m-2 in 24 h (Fig. 2). The biggest carrot plant
photosynthesis productivity was fertilizing with monomial fertilizers, but essential
differences among plants fertilized with different fertilizers weren’t found. The biggest
crop net photosynthesis productivity was applying fertilizer with nitrification inhibitor
(Fig. 2).
