The need to develop and implement innovative forms of reforestation to obtain highly productive tree stands actualize the topic of the article. The purpose of the work is to study and analyze foreign experience and research on the production of softwood containerized planting stock for reforestation and compare it with the practice of greenhouse complexes in the Arkhangelsk region. We used the international bibliographic and abstract database «Scopus», which indexes scientific journals, materials from conferences and publications to search for information. A review of publications has been completed over more than a 20-year period (1999-2019). The world experience study and the results of studies on the cultivation of forest containerized seedlings, in particular, Finland, Sweden, Norway, countries similar in terms of the growth of woody vegetation and the range of tree species to the conditions of the European north of Russia made it possible to highlight current research directions. The treatment of seedlings with a short or long light day; frost resistance of the seedlings; influence of drought, excessive moisture; issues of seedling storage; diseases, pests of seedlings and control of them, as well as problems of selection and seed production; seed quality and their impact on plant growth; influence of cultivation technology and types of planting stock on the effectiveness of planting refers to them. The use of foreign plants for growing ball-rooted planting stock implies a similar technology for the production of forest seedlings in our region. However, climatic features and the availability of various consumables, such as peat, fertilizers, pesticides, etc., necessitate the adaptation of Scandinavian technologies to local conditions and the development of additional techniques. One of the main production tasks is the achievement of standard indicators by seedlings. It is not always possible to achieve the desired results in harsh taiga conditions, therefore it is necessary to use foreign experience in growing ball-rooted planting stock, which allows to increase the production of standard seedlings without compromising their quality. This is a whole range of measures, including work on breeding and seed production, the formation of a plant substrate, lighting, moisture, observing the temperature regime, storage of seedlings, combating diseases and pests, etc., which ultimately are the components of the success of artificial reforestation

Meadow fescue (Festuca pratensis Huds.) is grown widely in the Nordic countries in forage grass mixtures. Locally adapted cultivars are preferred for establishment of mixed swards. Meadow fescue seed yield is determined by seed weight, the number of panicle bearing tillers, size of panicles and the number of fertile florets. We aimed to determine the differences in components of seed yield in two different meadow fescue cultivars differing in forage quality; Kalevi, released in 1979, and Fure, released in 1999. Biomass accumulation was monitored, numbers of fertile and sterile florets, and seeds were counted, and the forage quality was analysed. Seed quality was also analysed. Fure was leafier and accumulated more vegetative biomass than Kalevi. Kalevi had significantly more panicles than Fure, although Fure compensated for the lower number of panicles with increased panicle size. There were no differences in number of sterile and aborted florets between cultivars. Based on the results it seems that these two meadow fescue cultivars have a completely different strategy in seed production even though the final seed yield was not markedly different. It is apparent that meadow fescues have good ability to compensate among the components of seed yield. Long-term field experiments should be conducted to investigate the interactions between plant stand ecology, seed production and cultivation technology.;

Six trials were conducted on commercial seed fields of creeping red fescue (Festuca rubra L. var. rubra) in the Peace region to evaluate the sensitivity of seed production to the method and time of application of N fertiliser. In each trial, 68 kg ha−1 N was applied using three methods (surface-broadcast, granular, ammonium nitrate 34-0-0; foliar/soil spray of 28-0-0 solution N; soil-injected 28-0-0 solution N) at each of three times (fall, early spring, late spring). No statistically significant (P = 0.05) interaction, or main effect, of method and time of N were revealed for seed yield, fertile tiller density or for several seed quality characteristics. Seed yield varied greatly among trials (142 to 1240 kg ha−1) and averaged 566 kg ha−1. The results indicate that there is considerable flexibility in the method and time of application of N fertiliser for seed production of creeping red fescue in the Peace region, provided it is applied before the commencement of vigorous plant growth in the spring.

Seed Yields

Preharvest applications of glyphosate have been shown to be effective in controlling Canada thistle in annual crops, but may reduce alfalfa seed yield depending on time and rate of application. The objective of this study was to determine the effect of preharvest applications of glyphosate on subsequent alfalfa seed yield and quality. The effects of timing, 1, 26, 51 and 76% alfalfa seed pod maturity, and rate, 0, 440, 880, 1320, and 1760 g a.i. ha-1, of a preharvest application of glyphosate on alfalfa seed yield and quality in the year of application, and regrowth and seed yield in the following year were determined. The rate of glyphosate applied did not affect seed yield in the application year; however, in the following year, growth and seed yield were reduced as rates increased. Delaying the application of glyphosate increased seed yields in the application year, but decreased alfalfa regrowth and flowering the following year. Germination and seedling emergence were not affected by the rate or timing of the glyphosate. A preharvest application of glyphosate at 1760 g a.i. ha-1 at 76% pod maturity is a viable option in the last year of seed production.

SUMMARYA review of the outcomes of past attempts at establishing sustainable seed producer groups in Nepal showed that after donor support was withdrawn a lack of marketing skills resulted in the groups no longer producing seed. Learning from this review, when we initiated new attempts at establishing sustainable seed producer groups in Chitwan district, Nepal, we emphasized the strengthening of their marketing and managerial capabilities rather than training in technical issues such as seed quality control. We imparted marketing skills to committee members of farmer groups at an initial training course in Chitwan in 2001. This inspired at least three existing farmer groups in Chitwan, already established for other agricultural activities, to enter into cereal and legume seed production and its marketing. Following their establishment in 2002 we supported them initially by purchasing some of their seed production. This was progressively withdrawn and, after three years, the groups independently marketed all of their substantial seed production. They built up capital reserves mainly from subsidies and by attracting funds from new shareholders with only a small contribution from retained profits that were only about 5% of total turnover. The capital reserves reduced or eliminated the need for loans thus increasing the chances that the enterprises would be sustainable. In contrast, other government-supported groups had practically no cash reserves despite substantial seed sales. By 2010, two of the three groups were still operating and had substantially increased turnover. Shareholders who were also seed producers benefited from being members of the group and from an increased income of 10% by producing seed instead of grain. Our intention in supporting these groups was to promote the scaling out of new rice varieties produced by client-oriented breeding (COB) or identified by participatory varietal selection but most of the seed that was produced was of obsolete varieties. Policies are needed to preferentially promote new varieties by supplying more information about them and increasing the subsidy on their seeds compared with older varieties. Continuing promotion by the organizations that bred them is also desirable but constrained by limited funding for COB.

The quality of seed needs to be considered in carrot seed production to maintain its productivity. The research aims to find out the response of stecklings age and plant spacing on carrot seed quality and production. This research was held on July 2018 – April 2019 in Berastagi field trial (1340 m MSL). The experiment used Randomized Complete Block Design (RCBD) with two factors, i.e., stecklings age (2 and 3 months) and plant spacing (25, 50, 75, and 100 cm), replicated four times (32 experiment units), 10 plants from each experiment units were taken as samples. The result showed that stecklings age and plant spacing were affected to plant vegetative and generative stages. The combination of 2-month stecklings and 50 cm plant spacing increased the number of secondary umble, if compared to cultivation, which was generally used by the farmer (3-month stecklings and 25 cm plant spacing). The best quality of carrot seed was obtained from the combination of 3-month stecklings and 50 cm plant spacing.

The method of allocation of zones of seed production of agricultural plants depending on soil and climatic factors is developed on the basis of the established four types of seed yield: type I - high yield, high seed quality; type II - high yield, low seed quality; type III - low yield, high seed quality; IV - low yield, low seed quality. Data on crop types were plotted on a contour map of the studied administrative subject (region, territory, republic) with the designated boundaries of districts and soil-climatic zones, as a result, 4 possible zones of seed production were identified: 1- the zone of optimal seed production, in which the seed farms form the I type of crop; 2 - the zone of risky seed production (II type of crop); 3 - the zone of permissible seed production (III type of crop); 4 - the zone of unacceptable seed production (IV type of crop). The network of seed farms should be organized primarily in the areas of optimal seed production. When organizing the production of seed material in the zones of permissible seed production, it is necessary to increase the yield by improving agricultural technologies. In the zones of risky (II type of crop) and unacceptable (IV type of crop) seed production, it is not advisable to produce seed material.

The Higher Education Community Empowerment Program (PPMUPT) activity aimed to disseminate research results on design engineering and construction materials for verticultural cultivation of seaweed; Seed quality from seaweed cultivation centers in North Sulawesi; and Co-cultivation of seaweed and sea tilapia. The implementation partnered with the Nain Princess and Mekar Laut Groups, and was supported by the Nain Village Government. The three partners expressed their willingness and ability to work together in formulating and finding solutions to problems, as well as planning the implementation stages and all of these activities. In addition, partners continue to contribute throughout the activity. Formulation of problems with partners, are: Is there a technology that can minimize disease attacks on seaweed. The solution is in the form of: a. Engineering design and construction material for cultivation containers, b. Verticultural cultivation of engineering methods. The method applied was the classical and individual approach in the form of class lectures, demonstrations, and practices about the innovation of seaweed cultivation technology. The outputs of the PPMUPT activities were productive economic partners that have increased knowledge, skills, quality, quantity, and types of products. Participants were principally satisfied with this PPMUPT activity, and even 92.86% stated that they were very satisfied in participating in PPMUPT activities regarding the use of strings as ris ropes with seaweed verticulture methods.
