PROCESS FOR PRODUCING COMPOSITIONS INCREASING THE GRAIN CROP AND OECOLOGICAL RESISTANCE OF MAIZE BY THE CONTROL OF ENZYMATIC PROCESSES AND TREATING THE PLANTS

摘要

Yield and environmental resistance of maize crops is increased by spraying with chemicals influencing the hormone and enzyme activities of the plants belonging to different varieties planted in alternating rows for cross fertilisation, the two varieties differing both in gestation period and in height.
