Influence High Temperature, Drought and Long Vegetation Period on Phenology and Seed Productivity European Hemp Cultivars in Moinkum Desert

Wild hemp is one of the most valuable technical plant caused by sexual dimorphism: the differences in rate floras of Kazakhstan.Generally, it is accepted that the of growth and development between male and female most economically advantageous became fromthe plants are large [9]. The male plants tend to flower and cultivation of cultural fibre hemp varieties. The fibre hemp senesce earlier. Also within the same sex, large plants (Cannabis sativa L.) is grown for a multitude of end are suppressing smaller ones and thus plant-to-plant products derived from the cannabinoids, seed, fibre variation can become considerable and may even and wooden core. As a fibre crop, it is one of the oldest result in self-thinning [10]. Particularly in dense non-food crops world-wide [1]. Moreover, it is very high stands intraspecific competition generates a size yielding compared with many other crops [2]. According hierarchy and thus increases variability [8]. In the world to Struik [3] fibre hemp may yield up to 25 t above ground about 10 places where are hemp grows high in dry matter per hectare (20 t stem dry matter ha ), which cannabinoids, particularly THC. One of them is the 1
