Relevance. Chicory root (Cichorium intybus) is a very valuable technical, vegetable and medicinal crop. The development and improvement of a scientifically based fertilizer system is one of the most important issues in agricultural production, since it determines not only the level of crop yield, but also the direction of changing, increasing and preserving soil fertility in general.Material and Methods. The aim of the research was to identify the most effective doses of mineral fertilizers and methods of their application (basic and top dressing) to ensure maximum yields of root chicory root crops. The research was carried out in 2021-2022 in the field of the Rostov Vegetable experimental station on chicory – Branсh of the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Center. Chicory seeds of the Petrovsky root variety were used for sowing. Mineral fertilizers were applied in the form of azophosphate and potassium sulfate.Results. On sod-podzolic soils, the use of mineral fertilizers had a positive effect on the yield of chicory root crops. The more developed the leaf rosette of plants, the higher the yield of root chicory.Conclusion. In the soil and climatic conditions of the Non-Chernozem zone of the Russian Federation, the greatest effect from the use of mineral fertilizers on root chicory is observed with a mineral nutrition system that includes the main application at a dose of N60P60K60 and top dressing at a dose of N60P60K60.

Relevance. The climatic conditions of the Primorsky Territory, the determining factors of which are its geographical location at the junction of the continent of Eurasia and the Pacific Ocean, are unique, which determines the main directions of breeding vegetable crops at the Primorskaya Vegetable Experimental Station – branch of the Federal State Budgetary Scientific Institution «Federal Scientific Vegetable Center» (PVES – branch of the FSBSI FSVC). The article provides an overview of the main achievements of the station's scientists' long-term work on tomato breeding for open ground and identifies the main tasks for further development of this area in the conditions of the south of the Russian Far East.Results. Based on the results of many years of research, the model of tomato variety of universal type for open ground was specified taking into account the requirements of the modern market of Primorsky Krai: ripeness group – medium-early or medium-ripening, short sprouting-flowering period; determinant plant, compact with medium or high foliage and medium-sized leaves (important for mechanized cultivation); brush – simple or intermediate; stalk – without articulation or with thickening (easy fruit detachment); fruit – of different shape, weight 60-100 g dry matter content not less than 5%, with uniform coloring without a spot at the stalk in milk ripeness and different coloring in biological ripeness, resistant to cracking, vertex rot, with high storability and transportability; resistance – to sudden temperature changes, soil overwatering, high temperatures and air humidity during the fruiting period, to diseases of various etiologies, primarily to Alternaria and Phytophthora. Since a significant factor in reducing the productivity of varieties are diseases (as a result of increasing aggressiveness and expansion of the species composition of pathogens), the priority at present is breeding for immunity. Within this framework, intensive search for valuable sources and creation of new source material based on hybridization, individual and family selection from the best varietal and hybrid populations is carried out. Among the achievements of breeding of PVES promising are varieties Fitilek and Echo (tolerant to Alternaria), varieties Odyssey, Patrokl and Summit (tolerant to Phytophthora), on the basis of which parental lines are created. The breeding process also involves the most adaptive open field varieties of FSVC selection and the source of group resistance to Alternaria and Phytophthora - variety Ottava 30.Conclusion. Creation of targeted breeding achievements will allow to expand the variety range and saturate the vegetable market of this economically important region of the south of the Far East Primorye with domestic varieties within the framework of the import substitution program.

Relevance. In the harsh climate of the Arctic, where the warm season with a maximum average daily temperature above 10 °C lasts only three months, scientists in the crop industry are conducting tests and creating unique varieties of crops that will be able to provide the northern regions with fresh and vitamin-rich vegetable products.Materials and Methods. In the Nenets Autonomous Okrug, at the Naryan-Mar Experimental Agricultural Station, an innovative technology for priming seeds of vegetable legumes with electromagnetic exposure developed by JSC «Concern GRANIT» with the «TOR» device was tested on domestic varieties of Pisum sativum L. и Vicia Faba L. selected by the Federal Scientific Vegetable Center (FSBSI FSVС).Results. The tested varieties of vegetable legumes beyond the Arctic Circle were able to fully realize their productive potential, and the results of observations of the growth and development of crops confirmed the presence of favorable conditions for the selected crops. The quality of vegetable products and the obtained seeds of vegetable legumes in the Arctic in 2024 turned out to be higher than in the Moscow region due to a lower phytopathogenic load. Electromagnetic priming with the «TOR» device made it possible to obtain, in the conditions of the Far North, the productivity of green peas in responsive varieties and seed productivity in beans – by 3-16% and 12-35%, respectively, more than in control. Thanks to the use of the «TOR» device, acceleration of ripening, an increase in yield and product quality are noted, which is especially important in the conditions of a short growing season. Thus, favorable conditions and competitive opportunities for agriculture in the geographical location of the Russian North provide good opportunities to produce organic products in ecologically clean areas, which will be competitive not only in the regional, but also in the national and international food markets.

Relevance. Ethiopians have a long history of planting trees, and they have embraced the idea of keeping natural trees with many uses as a distinctive feature of their agricultural landscapes. Farmers use agroforestry practices to maintain a number of species of multipurpose trees. The selection of tree species, their intended benefits, and ecological services are inconsistent due to variability in agroecological conditions. The main problems with Ethiopia's multifunctional agroforestry tree species were also related to management approaches.Therefore, the purpose of this article is to examine the multipurpose agroforestry tree species in Ethiopia, their management methods, and their ecological benefits. In southern Ethiopia, Cordia africana, Millettia ferruginea, Erythrina brucei, and Olea capensis are the main multifunctional tree species used. The northern part of Ethiopia hosts Croton macrostachus, Vernonia amygdalina, Faidherbia albida, Acacia nilotica, Acacia seyal, and Grewia bicolor. The central highlands of Ethiopia are also home to Albizia gummifera, Cordia africana, Croton macrostachus, Ficus vasta, and Vernonia amygdalina. Farmers use coppicing, pollarding, and pruning tree management techniques to balance their survival with integrated crops because trees regenerate naturally. Multipurpose trees offer a range of agro-ecological services, such as improving soil fertility, mitigating erosion, mitigating the impacts of climate change, and maintaining biological diversity.

Tomato is one of the most important and widely grown vegetables in the world. The aim is to review the key challenges on tomato production and marketing in Ethiopia. In Ethiopia, tomato production is concentrated in river, valleys and lakes, especially in Awash Valley and around Lake Ziway for favorable growing conditions, good access to market outlets and better infrastructure. Tomato production is commercially important for fresh fruit market and processing. Some of tomato varieties that have been in use by farmers are used for processing and for fresh marketing. However, several constraints caused inconsistent of tomato production and low yielding’s are; the shortages of improved varieties, inadequate transport, poor marketing system, poor cultural practices, unreliable rainfall, price fluctuation, product nature (perishability), post-harvest losses, pest and diseases. Lack of market linkages, post-harvest losses, low institutional support, lack inputs and transportation are the key challenges. Small-scale producers are struggling to gain market access, but due to listed challenges the farmers are not selling their produce in an organized system and not getting the right shares. Therefore, critical attentions in harvesting and postharvest operations are very important to reduce losses, to keep quality and market standards. Moreover, addressing both production and market-related challenges are essential to minimize the losses, to access quality goods and to ensure the right shares for producers, distributors, processors and traders.
