INFLUENCE OF PHOTOSYNTHESIS ON PRODUCTIVITY OF THE CASTOR-BEAN TREE

The greatest crop can be received at the rapid growth of optimal leaves area, increase of their activity time, maximum photosynthesis and large daily gains of the organic substance. Studying features of photosynthesis of different plants will certainly promote the increase of person opportunities in managing their photosynthesis, productivity and crop. In the conditions of the southeast of Kazakhstan the castor-bean tree wasn't cultivated earlier, these researches are conducted for the first time. Therefore studying the main methods of cultivation of castor-bean tree and the photosynthesis influence on productivity of castor - bean tree in terms of a desert zone are of practical importance [3].
