Allelopathic effects of Androstachys johnsonii Prain on germination and growth of Zea mays L. and Vigna subterranea (L.) Verdc.

Allelopathic effects of the donor plants are mostly regarded as harmful to target plants such as traditional crops. Traditional crops play pivotal role as staple food for rural communities and hence ensuring food security. Study of the allelopathic effects of Androstachys johnsonii Prain on the germination and growth of Zea mays L. and Vigna subterranea (L.) Verdc was conducted. Different plant leachates concentrations of 0.675%, 1.25%, 2.5% and 5% were prepared through serial dilutions. Germination bioassays were arranged in a complete randomized setup of three replicates for each treatment for seven days. Germination rates were calculated, radicle and hypocotyl lengths were also measured. Germination rates of Z. mays L. and V. subterranea (L.) Verdc. ranged from 50 - 100% and 18 - 76%, respectively. Significant differences of P< 0.005 were noticed from the germination rates of V. subterranea (L.) Verdc subjected to high concentrations of different extracts used. Statistically there was no significant differences between germination rates of Z. mays L. treated with all concentrations of leaf leachates against germination rates of the seeds treated with distilled water. Outstandingly, the germination rate and early growth of Z. mays L. were promoted by less concentrated extracts of leaf, root, stem bark and soil which then suggest future use of allelochemicals from Androstachys johnsonii Prain for promotion of maize plant productions. Based on the beneficial attributes of allelochemicals from Androstachys johnsonii on the germination and growth of Z. mays L., planting of Androstachys johnsonii Prain in maize fields is highly recommended.

Marketing: Farmers Promulgates Cash Crops, Itinerary to Support Their Livelihood and Enhance Their Living Standard

This paper is a briefing on the marketing and emergence of cash crops in the Indo-Bangladesh border, South West Khasi Hills District Meghalaya. It is solely aimed at understanding the inborn entrepreneurship skills of the particular sub-tribe of the Khasis called "War". They live in steep and sloppy mountains with moderate temperatures and receive sufficient precipitation throughout the year, which enables them to sustain their farming. Marketing is the heart core of every individual, regardless of any background and professionals. Marketing plays a very important role to the farmers, and everyone could enhance their standard of living due to the technique of commercialization. The Non-farmers can buy the food crops from the farmers through the role of business administration. It is pointless to have money without having a food supply. Thus, the commercialization of agricultural produce is highly required. Cash crops cultivation promotes economic growth and social growth; economically, people can generate income, put savings, and purchase physical capital. Socially they bridged with each other, helping one another, exchanging work, advising the younger ones, and imparting knowledge to one another, providing seeds and saplings to the have not. There is an evolution from practicing traditional crops, which can be consumed directly, to Cash crops, which need to be exported outside of the State through a marketing system with the intention to manufacture further for finished products.

The Importance of Technical Support in the Return of Traditional Crops in the Alps: The Case of Rye in Camonica Valley

Multifunctional agriculture could be strategic for the recovery of some mountain areas of the Alps, and traditional crops like cereals generated study cases that triggered processes of development, such as rye in Camonica Valley (Northern Italy). However, farmers are often newcomers, and the specificities of low input agriculture make the training in agriculture fundamental. The impact of public workshops/seminars (organized by the Ge.S.Di.Mont. Research Centre of the University of Milan in Camonica Valley) on cereal cultivation between 2016 and 2021 was investigated. Moreover, rye produced in Camonica Valley was analyzed. The results show an increase in participation and a wider use of the streaming service. The percentage of participants not from an agricultural background had always remained about 50%, but decreased to 15.17% ± 5.07 in 2021, in contrast to the increase of professionals in agriculture and forestry. This is probably due to the accreditation of training activities for agronomists and foresters, and to the start of specific training projects regarding cereals. Samples of rye produced in Camonica Valley following the period of training activities were phytochemically/nutritionally characterized and compared to commercial rye. Locally produced rye proved to be comparable to the commercial one; however it showed a remarkable unevenness in secondary metabolite content and productivity, due to environmental differences and diverse agro-techniques.

Leaves of non-traditional crops in the production of food for a healthy diet

In the course of the study, it was determined that the chemical composition and nutritional value of the Viburnum vulgaris is explained by a group of substances of different nature. Their qualitative and quantitative component depends, first of all, on the growing region. The national economic value of viburnum is great—from culinary delights to medicines. The article presents the biochemical composition of the leaves of the viburnum of various varieties, which indicates the possibility of using viburnum leaves in the production of food, including a functional orientation.

Comparison of the antioxidant potential of some herbal teas produced from ecological and traditional crops

The growing public awareness of the dangers regarding chemicals used in traditional agriculture has led to consumers seeking valuable and contaminant-free products. Ecological agriculture has become synonymous with high health value and product safety. The aim of this study was to evaluate the antioxidant activity and the total polyphenolic content of infusions of herbal tea bags and loose teas from traditional crops, as well as infusions of loose teas from ecological crops. Raw material comprised dried flowers of Matricaria chamomilla and Tilia cordata, as well as dried leaves of Urtica dioica, Melissa officinalis and Mentha piperita. Herbal infusions were prepared using three brewing times: 5, 10 and 20 min. The analysis of antioxidant potential was performed using in vitro methods such as DPPH, ABTS and FRAP. The polyphenolic content was determined using the Folin-Ciocalteu method. The antioxidant activity of the studied tea infusion depended on the method by which the plants were cultivated and the brewing time. The ecological agriculture conditions seem not to stimulate the synthesis of antioxidants. However, the possibility to obtain other beneficial properties of the studied plants is an indication to carry out ecological cultivation.

Hunger by Choice? Rethinking Food Security Strategies

Food insecurity is a global threat with devastating effects, particularly in ‘developing’ countries. This threat is worsened by a parochial perspective in most of southern Africa that associates food security with the major staple crop maize. This bias is witnessed in the amount of land, investments, research, and marketing allocated to maize, in comparison to traditional crops such as millet, rapoko and sorghum. However, increased investments in agriculture, particularly maize production has failed to translate to increased production of the crop, particularly in Zimbabwe. The vagaries of climate-change manifested through droughts, coupled with man-made policy disasters are evidence enough to factor diversified production systems to include traditional crops into the food security basket. Since independence in 1980, Zimbabwe has experienced more than a dozen drought periods, which translates into multi-million dollar food imports. To feed the growing number of food insecure people, the solution could be in the shunned small grains, whose resilience in harsh conditions compared to maize, calls for urgent transformation and orchestration of the food security basket. Through renewed focus on traditional crops, Zimbabwe and other countries in east and southern African could attain food secure status and ensure that food as a human right is available to all.
