“…The public requirement for harmless production of tea calls for greater rigour because tea is processed from buds and leaves, which are sensitive areas for the access of chemicals to the plant. The effects of HpaG Xooc and its functional fragments on green tea provide an alternative to the organic planting system that integrates multiple measures in watering, fertilizing, and control of diseases and insects into a procedure of management applied throughout the farming season (Geldermann and Kogel 2002;Sauerborn 2002). Moreover, using proteins as the active ingredients of spraying mixtures (Fontanilla et al 2005a, b) is simpler, and more acceptable by the public in contrast to the recalcitrance regarding some other approaches, such as genetic engineering (Stuiver and Custers 2001;Jang et al 2006).…”

Harpin proteins from plant pathogenic bacteria can stimulate hypersensitive cell death (HCD), drought tolerance, defence responses against pathogens and insects in plants, as well as enhance plant growth. Recently, we identified nine functional fragments of HpaG;Xooc, a harpin protein from Xanthomonas oryzae pv.oryzicola, the pathogen that causes bacterial leaf streak in rice. Fragments HpaG;1-94'HpaG;10-42, and HpaG;62-138, which contain the HpaG;Xooc regions of the amino acid sequence as indicated by the number spans, exceed the parent protein in promoting growth, pathogen defence and HCD in plants. Here we report improved productivity and biochemical properties of green tea (Camellia sinensis) in response to the fragments tested in comparison with HpaG;Xooc and an inactive protein control. Field tests suggested that the four proteins markedly increased the growth and yield of green tea, and increased the leaf content of tea catechols, a group of compounds that have relevance in the prevention and treatment of human diseases. In particular, HpaG;1-94 was more active than HpaG;Xooc in expediting the growth of juvenile buds and leaves used as green tea material and increased the catechol content of processed teas. When tea shrubs were treated with HpaH;Xooc and HpaG;1-94 compared with a control, green tea yields were over 55% and 39% greater, and leaf catechols were increased by more than 64% and 72%, respectively. The expression of three homologues of the expansin genes, which regulate plant cell growth, and the CsCHS gene encoding a tea chalcone synthase, which critically regulates the biosynthesis of catechols, were induced in germinal leaves of tea plants following treatment with HpaG;1-94 or HpaG;Xooc. Higher levels of gene expression were induced by the application of HpaG;1-94 than HpaG;Xooc. Our results suggest that the harpin protein, especially the functional fragment HpaG;1-94, can be used to effectively increase the yield and improve the biochemical properties of green tea, a drink with medicinal properties.

“…Environmental aspects of farming are mainly related to the intensity of production (Geldermann and Kogel 2002). Sugar beet differs from other crops in that it is mainly characterized by production costs, labour hours, and use of production factors (varieties, pesticides and fertilizers) and natural resources (water and soil).…”

The environmental situation and current yield performance of sugar beet production in Germany are described and compared to those in other European regions. A continuous increase in yield performance and enhanced technical quality have been achieved through progress in breeding and improvements in crop management systems. This rise in yield potential has been brought about not by increased production intensity, but by better use of natural resources and production factors. In Germany, legislation rules many environmental aspects of agricultural plant production, and special laws are in force concerning fertilizer use, soil protection, and pesticide use. In sugar beet, nitrogen fertilizer use has decreased greatly and may be reduced further in some regions. A further reduction of potassium and phosphorus fertilizer use does not seem to be appropriate. Conservation tillage contributes to soil protection and is already performed on > 100 000 ha of land growing sugar beet. Strategies of integrated production aim to reduce pesticide use to the bare minimum. Integrated pest management is effective to control insects, nematodes and leaf spot diseases. Pesticide use in sugar beet is dominated by herbicide application. The most promising strategy to reduce the amount of active ingredient seems to be the growing of genetically modified herbicide‐tolerant varieties. Possible directions for future research are discussed, and the prospects for sustainable development, in terms of economic, ecological and social factors, are considered.

“…This concept is based on a new understanding of the economy as a subsystem of society and nature, a tool for achieving a socially just and environmentally stable future, because the planet does not have time to renew itself and the state increases the volume of production, wasting resources and causing many problems with risks, crises, instability, uncertainty and volatility of development (Buhaychuk, Nikitenko Voronkova, Andriukaitiene, & Malysh, 2022). Geldermann and Kogel states that considerations of global agricultural production in the future must take into account the certainty that the world population will increase (Geldermann and Kogel, 2002). Figure 1 shows the growth in the number of people to a projected 9.5 billion in 2050.…”

The relevance of the problem under study is that the concept of the development of the "blue economy" represents the most modern development of ecopolises based on the ingenuity of ecosystems and the provision of numerous products and services on which human life and humanity depend. The aim of the article is to create conditions for the development of a "blue economy" as the basis of an ecologically sustainable ecopolis, in which a new culture of agro-ecology is revived as a new type of agricultural product. This study identifies the problems of today's agricultural production model, which generates a lot of waste and leads to genetic manipulation. The "blue economy" as a new direction of production cultivates the effective development of waste potential, demonstrating the evolutionary path of nature, which restores its balance and evolves from scarcity to abundance. The main approach of the study is the systemic method, which makes it possible to show the development of the "blue economy" as a system consisting of interconnected components that function as a whole, as well as methods for modelling the processes of a regenerative economy, of which the "blue economy" is a variety. People live in a complex system of the natural environment, in which they face the problems of environmental pollution, the overcoming of which leads to the need for new types of circular economy, of which the blue economy is a variant. The article analyses the conditions for the emergence of a "blue economy" based on the ingenuity of ecosystems to continue to provide humanity with the best products on which the quality of sustainable human life and the capacity of society to renew itself depend. Today's agricultural production is a model that produces a lot of waste, which can be used to process weeds, to make animal feed and to develop "coffee chemistry" by growing mushrooms on coffee biomass. The "blue economy" as a new direction of agricultural production can be a response to the innovative development of the food industry – from food to the production of animal feed and ingredients for cosmetics – which represents the formation of new values of the "blue economy" as a sustainable provision of new products. The combination of sustainable agriculture, new agricultural production and human health requires innovation and the development of the blue economy as a new culture of agroecology – environmentally friendly products and food.
