At a time when the introduction of any novelty in production or agriculture is being considered in the light of the damage to nature, and society is finally beginning to measure its technological progress with the degree of conservation, alternative crops are turning out to be a small fortune. The pursuit of sustainable development, declining agro-biodiversity and the health benefits associated with unique nutritional qualities are the main reasons for exploring and growing new alternative crops. The purpose of this study is to develop efficient agricultural production and the application of alternative agriculture in the area. The reasons for the need of the study are the fragmented and low-fertile land and the orientation of the Rhodopes agriculture towards ecological production and the requirements of the European market. The study included fiber, energy, oil and protein crops as alternative tobacco crops in the geographical territories of the Eastern Rhodopes - the districts of Kardjali and Haskovo. It was found that the fields with annual crops in the lands of the town of Ivaylovgrad in the Haskovo district realized higher yields than the respective studied crops. Of all the thirteen crops, the highest development and high yields were found in spelled, triticale, safflower, miscanthus, olives and almonds during the study period, and yields of hemp, flax, rapeseed, soybean, sorghum and buckwheat were unsatisfactory.
