EFFECT OF SOME HERBICIDES AND THEIR MIXTURES WITH GROWTH REGULATOR AND FOLIAR FERTILIZER ON PROTEIN CONTENT IN COTTON (Gossypium hirsutum L.) SEEDS

For the first time in the world we established that the highest protein content in seeds of cultivar Helius was obtained with vegetative treatment with herbicides Goal 2 E, Linuron 45 SC, Wing P and Merlin 750 WG. The highest protein content in seeds of cultivar Darmy was obtained with vegetative treatment with herbicides Goal 2 E, Wing P and Basagran 480 SL. The highest phytotoxicity on protein content in seeds of cultivar Helius was shown by the herbicide Basagran 480 SL and all herbicide combinations with the growth regulator Amalgerol and the foliar fertilizer Lactofol O. The strongest phytotoxic effects on seeds of cultivar Darmy was produced by the herbicides Linuron 45 SC and Merlin 750 WG and herbicide mixture Wing P + Lactofol O. For the first time, we established that, from the point of view of the technology for cotton growing of cultivar Helius, the most valuable are tank mixtures Goal 2 E + Amalgerol, Linuron 45 SC + Amalgerol, Goal 2 E + Lactofol O, as well as the single use of herbicides Goal 2 E, Linuron 45 SC, Wing P and Merlin 750 WG. Technologically the most valuable in cotton cultivar Darmy were herbicide combinations Goal 2 E + Amalgerol, Wing P + Amalgerol, Merlin 750 WG + Amalgerol, Basagran 480 SL + Amalgerol, Goal 2 E + Lactofol O, Linuron 45 SC + Lactofol O, Merlin 750 WG + Lactofol O and Basagrain 480 SL + Lactofol O, and the herbicides Goal 2 E, Wing P and Basagran 480 SL.
