Abstract

The trial was carried out during 2013-2015, with twelve cotton cultivars (Gossypium hirsutum L.). Influence of herbicides Bazagran 480 SL (bentazone), Pulsar 40 (imazamox) and Express 50 VG (tribenuron-methyl) was studied. These herbicides were used during the budding stage of cotton. The herbicide Bazagran 480 SL has the highest phytotoxicity on the primary germ length of seeds of cotton cultivars Chirpan-539 and Trakia and the lowest on cultivar Natalia. The herbicide Pulsar 40 has the highest phytotoxicity on the primary germ length of seeds of cotton cultivar Dorina and the lowest on the cultivars IPK-Veno and Viki. The herbicide Express 50 VG has the highest phytotoxicity on the primary germ length of seeds of the cotton cultivar Chirpan-539 and the lowest on the cultivars Helius and Trakia. From the viewpoint of cotton growing technology, technologically the most valuable are all cultivars, by foliar treatment with herbicide Bazagran 480 SL. Technologically the most valuable are cultivars Viki, IPK-Veno, Boyana and Natalia by foliar treatment with herbicide Pulsar 40. Technologically the most valuable are cultivars Helius, Trakia, Viki, Avangard and Nelina by foliar treatment with herbicide Express 50 VG. These variants combine high primary germ lengths and high stability of this index during the different years.
