The application of hemp (Cannabissativa L.) for a green economy: a review
TURKISH JOURNAL OF BOTANY, 2019
The concern for the issues related to the growing needs of human civilization like resource depletion, pollution, climate changes, and health risk has led to a search for eco-friendly alternatives to environmental problems. Recently, hemp started gaining popularity for its medicinal, nontoxic, greenhouse negative, and biodegradable properties. Originating from the steppes of Central Asia, Cannabis sativa L. (hemp) is one of the oldest domesticated plants known to humans. Since 5000-4000 BC, different parts of the plant were used for spinning, weaving, papermaking, the seed for human feed, animal feeds, medicinal, and health purposes. Reports also suggest the use of hemp as an organic additive in the historic earthen plasters of Ellora Caves, India (6th Century). Due to its psychoactive and recreational properties, this environmentally friendly plant lost its importance eventually in the 19th century and its cultivation was made illegal. People, in general, changed their outlook towards the plant and considered it a sign of moral indignation. Recently, food, pharmaceutical, textile, paper, building, energy, and other industries found hemp to be a promising solution for synthetic-based economies. Since then, the cultivation of hemp has been reintroduced, legalized in some countries, and now in recent times, there has been a good reimplementation of the plant in creating a green economy. This review will highlight the application of hemp and display its outstanding qualities in minimizing environmental and health issues. Based on the knowledge gained from various scientific resources; the commercial, industrial, and agricultural potential of the plant will be unveiled to give more push towards the hemp cultivation.
Introduction to emerging industrial applications of cannabis (Cannabis sativa L.)
Rendiconti Lincei. Scienze Fisiche e Naturali, 2021
The Italian Law of 22 November 2016 has legalized the cultivation of hemp, which drives the development of sustainable agriculture by generating new products with high added value in the new context of circular economy. Hemp cultivation is known for its low environmental impact, as hemp grows fast, suppresses weeds and does not need pesticides. It has no specialized parasites, favors pollination and improves the physical and chemical soil fertility. Recently, many countries have increased their interest in hemp (Cannabis Sativa L.), considering it as a climate-friendly crop that can mitigate climate change and desertification. For these reasons, hemp can be a new protagonist of Italian agriculture already oriented towards the objectives of EU 2030 which predicts 40% decrease in greenhouse gas emissions compared to 1990. The hemp cultivation can activate a new supply chain by allowing using different parts of the plant, benefiting farmers, environment, and human health. Indeed, altho...
Industrial Hemp (Cannabis sativa L.) Agronomy and Utilization: A Review
Agronomy
Currently, there are increased interests in growing grain and fiber hemp (Cannabis sativa L.) as well as in large-scale hemp products. Cannabis has been grown/utilized for thousands of years as a fiber, grain, and drug/medicinal plant. However, the strict control of cannabis cultivation to combat illegal use, the spread of new yarns and oilseeds, and the advent of cheap synthetic fibers caused a decreased/eliminated hemp production. Hemp has been banned in most of the world for more than seven decades; it missed out on the Green Revolution and the adoption of new technologies and varieties, creating a knowledge gap. After the 2014 and 2018 Farm Bill in the USA, hemp became legal and the land grand universities launched research programs. The ability to utilize the entire plant for multiple purposes creates opportunity for the market to value hemp products. Hemp production technology varies depending on the type of hemp cultivated (grain, fiber, or cannabinoids), soil characteristics...
Industrial hemp and its potential
2020
Hemp (Cannabis sativa L.) is an emerging high-value specialty crop that can be cultivated foreither fiber, seed, or cannabidiol (CBD). The demand for hemp and its products has been consistently onthe rise in the 21st century. The United States of America has reintroduced hemp and legalizedits production as an agricultural commodity through the 2018 Federal Farm Bill. Although thereis a renewed interest in the adoption of hemp due to the emerging market, its production in theUnited States remains limited partly because of unclear agronomic guidance and fertilizationrecommendations. This review article provides information on the current agronomic managementpractices that are available in the literature and identifies the future research needs for cultivating thismultipurpose crop to address the growing market demands. Hemp production could be beneficialif managed properly. Hemp fertilizer requirements vary in accordance with the type of hempgrown (seed, fiber, or CBD), soil, environm...
Cannabis sativa: Industrial Hemp (fiber-type)-An emerging opportunity for India
Cannabis sativa: Industrial Hemp (fiber type) An emerging opportunity for India, 2023
This literature review paper is presented as a part of the educational awareness about the Cannabis sativa, particularly the Industrial Hemp (fiber-type). Cannabis sativa was originally a native of India growing as a wild medicinal plant in the Himalayan region. The cultivation and use of Industrial hemp (fiber type) is historically rooted in the Indian subcontinent and this rich heritage of cannabis use dates back to at least two thousand years. Industrial hemp (fiber type) is a versatile commercial crop that has been used for fiber, food, medicinal purposes and building construction material, Hempcrete. Many studies have demonstrated that the nutrient and bioactive composition of hemp contributes to the prevention and treatment of several ailments suggesting its potential as a valuable functional food ingredient. Industrial hemp (fiber type) and medical Cannabis (marijuana type) have primarily been differentiated by their levels of Δ9-tetrahydrocannabinol (THC) production. Industrial hemp (fiber type) can be refined into a variety of commercial items, including paper, artificial hair, rope, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed. This review sought to highlight these advances in understanding the medical, nutritional, and nutraceutical benefits of industrial hemp (fiber type).
Processes
Hemp is a high-value crop that originated in Central Asia and is a historic but emerging cultivated plant. It may be grown for fiber, food, paper making, textiles, and therapeutic reasons. In the 21st century, market interest in hemp and its products has notably increased because seed portions can be utilized in the agri-food business, the woody component of the stem can be used in green buildings, the outer layer of the stems can be used in the textile industry, and the extraction of bioactive components from roots can play a vital role in the pharmacological industries. Hemp has recently been demonstrated to be a viable alternative for economies built on synthetic materials by the food, pharmaceutical, textiles, paper, building, and energy industries, among others. As a result, the goal of this study is to assemble the significant advancements in hemp, as well as to identify research gaps and research direction opportunities. The hemp plant will be provided more encouragement to b...

The last climate change forecasting and the water scarcity scenarios in many semi-arid agricultural areas worldwide, such as the southern Spain, are promoting changes in the crop pattern of irrigated agriculture, being introduced new species characterized by its water-stress tolerance. In the last few years, there is an increasing interest in the cultivation of industrial hemp (Cannabis sativa L.) to manufacture therapeutic products derived from non-psychotropic cannabinoids and other secondary metabolites. This work evaluates the agronomical response of two industrial hemp cultivars (Carma and Ermes) subjected to different management practices. The trial was conducted during two seasons (2012-2013), from April to October. During this monitoring period, different plant densities (PD), sowing times (ST), irrigation doses (ID) and cropping systems (CS) were evaluated. At the end of each season, yield parameters (fresh and dry weight, dry weight of flowers and leaves, and the ratio between this late and total dry weight) were obtained. Moreover, the content of the most relevant cannabinoids (CBG, CBD, Δ9-THC, and CBC) were measured in both cultivars, and for the different growth conditions considered. According to our findings, both cultivars evidenced similar responses with significant improvements for the earliest ST (at the end of April) and the highest PD (33,333 and 16,667 plants ha −1). In relation to the ID, not clear responses were observed in terms of active biomass production, being the effects depending on the interactions between PD and ST. Finally, it was noticeable the improvements related to the active biomass production and cannabinoids content when plants were grown under plastic macro-tunnels (among 1.3 and 2 times higher, depending on the cultivar) in comparison to the obtained results under open field conditions.
