THE EVOLUTION OF SEED PRODUCTION IN DIOECIOUS HEMP IN THE PERIOD 2016-2018, IN CLIMATE CONDITIONS FROM S.C.D.A. LOVRIN

Abstract

Hemp is a multi-purpose crop, being used mainly for the production of stems and fiber, seed, but also for food and medicine. In the western part of the country and not only, dioecious hemp finds favorable conditions for cultivation. One of the research centers in Romania, with a rich tradition in hemp breeding and cultivation is at S.C.D.A. Lovrin. Hemp is a plant with special requirements for temperature, humidity and fertilization. The optimum temperature at which the highest seed and stem productions are obtained is 20-22⁰C together with a good supply of pressing nutrients. During the analyzed period, 2016-2018 the climatic conditions had an atypical evolution, considerably influencing the harvest. The aim of the paper is to evaluate the production of a number of ten varieties, Romanian and foreign, from the S.C.D.A. Lovrin. Climatic conditions had a significant influence on production, the minimum production being recorded in 2017 (240 kg / ha - average experience) and the maximum in 2018 (786 kg / ha seed average experience).
