Ekonomi i vallfrödominerad växtföljd :

This is a project about how you grow timothy Seed and red clover Seed successfully. The main part is about economic analyse to see if it is any economy by growing leySeed. There are lots of things to be aware of to get all the costs in your economic analyze. Timothy Timothy Seed is planted on 4400 hectares in Sweden. It is possible to grow timothy Seed in the south part of Sweden. Timothy is very sensitive for dry weather in spring and in the beginning to summer. Timothy gives acceptable harvest of Seed for about three years. Red clover Red clover is also sensitive for dry weather and is suitable to grow in the south part of Sweden.

Interdependence between seed age and aerated steam treatment intensities

Aerated steam treatment is a modern and environmental friendly method for Seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of Seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between Seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of Seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a Seed lot, by testing the treatment tolerance of Seeds aged prior to the treatment.

Torkning av vallfrö :

In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the fields, this is primarily used as feed for livestock. To get a good Seed, you need to handle the crop carefully from planting to delivery. The part that I have been interested in, is how to dry the harvested Seed with out destroying the growth in the small Seed. This is very easily done if you aren?t careful during the drying period.

Sha Jun

The agriculture in Sweden today uses chemical substances to control vermin, weed and diseases. This usage shows through polluted subsoil water and trace elements in the food we eat. There?s a risk that additional symptoms will arise in the future. Our product Sha Jun, developed in 2006-2007, is an attempt to try and minimize the need of chemicals in the agriculture. The idea started with the attempt to minimize the usage of pesticides on the cropland.

Ekonomi i odling av ekologiskt potatisutsäde :

According to the EEG-councils regulation nr 2092/91, all Seed used in organic production must have organic origin. All Seed which is offered for sale must be controlled by KRAV, and also comply with the rules of the Seedlegislation. The Seedlegislation contains demands respecting origin, quality, growingconditions and freedom from deseases. In this piece of work I will investigate the profitability of organic potatoSeedproduction, and also what it takes to produce potatoSeed. The workmethod has been to, with help from counsellors and growers, make some compareable calculations for foodpotatoes and Seedpotatoes, and also with help from a literaturestudy investigate which requires an organic Seedcultivation must fulfil. In this piece of work I found out that the organic potatoSeedproduction still is to insecure to be profitable. The attack of potatoleafmould, which is out of control, cause unequal yields and this will bring that the new EU-rules, concerning organic Seed, not seems defendable yet..

Ny teknik för kombisådd :

The use of combi-drilling during spring tillage has become very common in southern Sweden in recent years. Combi-drilling leads to fewer passes on the field and better plant nutrient utilisation. An example of a combi-drill is the Väderstad Rapid, which is very widely used in spring tillage in southern Sweden. The Rapid has separate fertiliser and Seed coulters, which means that the draught requirement is relatively high. It thus requires large, heavy tractors, which compact the soil and are comparatively expensive to buy and run. A few years ago the Finnish combi-drill Tume Nova Combi came onto the Swedish market.

Småskalig utsädesproduktion : ekonomiska och organisatoriska aspekter

The economic situation in the Swedish agricultural industry is currently experiencing a development towards larger units. This progress occurs simultaneously as farmers in cooperation more frequently make investments to decrease risk exposure and to improve the financial result. The purpose with this thesis is to study which advantages and problems a group of farmers experience after a common investment in a small-scale Seed production. The aim with this investment is to increase the level of vertical integration in their respective agricultural firms and the results will be analyzed from an economic point of view. At present, the farmers are all Seed producers with considerable cultivation areas.

Fröskörd av hampa : metoder och tekniker för fröskörd av industrihampa

Hemp is an ancient cultivated plant that came to Sweden in the 1st to 2nd Century and was particularly interesting for use for food, clothing and building materials. Over time, other applications have been developed for hemp, e.g. in energy and health products. Interesting new uses for hemp continue to be identified and this fascinating plant has incredibly versatile applications.In this project, Seed production of industrial hemp in Sweden was studied and evaluated. Five different methods are described, four of which are proven under Swedish conditions.

Från frö till planta : En studie om hur elever i årskurs ett och fyra tänker om fröet och dess utveckling till planta

Abstract The aim of this study was to explore and describe the pupils' thoughts on Seed and its development into Seedling. Twenty nine Swedish pupils at the age of 7 and 10 years old were interviewed about their knowledge of Seeds.It turned out that pupils often have so-called everyday belief to describe the natural science phenomenon by connecting their explanations to phenomena in everyday life to which they are familiar. To describe the process of Seed developing into Seedling is something that most of the pupils believe to be difficult and this resulted mostly in the answer ?it is growing.? Children have some knowledge about what Seeds need in order to germinate but they do not mention the importance of oxygen as a component of Seed to be able to germinate and grow. They mean instead that it is sufficient with soil, water and sun.The older pupils, however, are more often than the younger pupils able to connect their reflections to a more scientifically correct description based on terms belonging to the phenomena, though these terms sometimes are wrongly used.

The effect of cold stratification on germination in 28 cultural relict plant species : with the purpose of establishing germination protocols

Cultural relict plant species from the Nordic countries have been collected by the Nordic Genetic Resource Center (NordGen) for the purpose of conservation. To ensure high Seed vitality in store, regular germination tests need to be conducted. It is important to get a correct viability status, but the knowledge of Seed dormancy in the cultural relict plants is often poor. The objective of this study was to investigate how Seed dormancy is affected by cold stratification. The study includes 31 accessions from 28 species with the purpose of establishing germination protocols.

Smart seed : fördröjd groning hos raps : försök med frö-coating samt litteraturgenomgång om frögroning, coating och praktisk tillämpning i reläodling

OilSeed rape constitutes a good break crop within a cereal dominated cropping system. The normal sowing time for winter rape in Sweden is August. It's a time in the cropping year characterized by a heavy work load, such as harvest and soil management. In addition, it is often a period with large precipitation. Thus, it is sometimes problematic for the farmer to do the sowing of winter rape at the optimal time.

Faderskapsanalys av tallfrö från Västerhus fröplantage : Skillnaden i pollenkontaminering mellan öppen pollinering och pollinering inom ett avgränsat system

In this study, pollen contamination (measured by the number of Seeds pollinated by pollen not belonging to any of the clones on the Seed orchard) is compared between open pollination and isolated pollination environments in a Scots pine (Pinus sylvestris) Seed orchard called Västerhus, located outside Önsköldsvik. In this Seed orchard a tent experiment is taking place. Skogforsk has built six large tents covering 12-14 trees with each tent. Fertilization patterns were compared between one tree in a tent with a supplementation of pollen from five clones not represented in the tent and another tree of the same clone subject to open pollination outside the tents. By using DNA markers the paternity was determined for 48 Seeds from each tree.

Skogssådd med tall och gran : effekter av fröegenskaper och skärm/hygge på plantbildning, överlevnad och tillväxt de två första åren efter sådd

Over the past few years the Swedish forestry industry has become increasing interested in direct Seeding. Although, in practice, this interest has been restricted to pine Seed, the knowledge and techniques that have been developed for pine Seeding can readily be transferred to spruce. Direct Seeding is a method that is of interest to the forestry industry since it can lead to lower regeneration costs, denser stands and better root development than the more conventional planting method. This study evaluated experiments that focused on direct Seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003.
