![]() ![]() The BBCH (Biologische Bundesantalt, Bundessortenamt and CHemische Industrie, Germany) scale is a system for the uniform coding of phenologically similar stages (stages of growth and development in ontogeny) in different species ofĭicotyledonous and monocotyledonous plants (Meier, 2001). ![]() Furthermore, it has been shown to be suitable for crop rotation due to its phytoremediation characteristics (Linger et al., 2002). Besides, hemp has been suggested by various researchers for the production of briquettes (Mankowski, Kolodziej, 2008), bioethanol (Tutt, Olt, 2011), biogas (Prade et al., 2011) and biodiesel (Rehman et al., 2013). Its fibre can be used for manufacturing of clothes, insulating material, or as a composite material (Karus, Vogt, 2004). INTRODUCTION Hemp (Cannabis sativa L.) has been grown for over 5,000 years for multiple purposes. Keywords: BBCH-scale, Cannabis sativa L., dioecious hemp, monoecious hemp, phenological growth stages Using the uniform coding system of the phenological stages of hemp is a valuable tool to ensure a more efficient planning and implementation of crop and soil management practices and techniques. The classification system of hemp growth stages presented in the paper is designed for hemp growers and researchers, including plant breeders, physiologists, entomologists and other agricultural producers. ![]() The principal growth stages are subdivided into secondary stages based on their main distinctive features. The growing season of hemp is divided into nine principal growth stages: germination and sprouting (0), leaf development (1), formation of lateral shoots (2), stem elongation (3), inflorescence emergence (5), flowering (6), development of fruit (7), ripening of fruit (8) and senescence (9). The current paper discusses the characteristics of principal growth stages of hemp (Canabis sativa), provides a brief description of these stages and of the coding system according to the BBCH scale. 11, LT-53361 Akademija, Kaunas Distr., Lithuania E-mail: 2 Phenological growth stages of hemp (Cannabis sativa L.): codification and description according to the BBCH scale Sergey Mishchenko1, Jurij Mokher1, Iryna Laiko1, Natalija Burbulis2, Hanna Kyrychenko1, Svetlana Dudukova1 Institute of Bast Crops of NAAS of Ukraine, Tereshchenko 45, Hlukhiv, Sumy Region, 41400, Ukraine 1Īleksandras Stulginskis University, Studentų St. ![]()
