Contribution of action researching to institutional innovation: a case study of access and benefit sharing (ABS) mechanisms in the participatory plant breeding (PPB) in Southwest China
This article investigates the contribution of action research to systemic institutional innovation, through a case study of access and benefit sharing (ABS) mechanisms developed in the context of a participatory plant breeding programme in Southwest China. The processes of purposeful change are examined as critical events, in eight episodes. Evidence is presented in these episodes of the role of ...

Seed systems for African food security: linking molecular genetic analysis and cultivator knowledge in West Africa
A challenge for African countries is how to integrate new sources of knowledge on plant genetics with knowledge from farmer practice to help improve food security. This paper considers the knowledge content of farmer seed systems in the light of a distinction drawn in artificial intelligence research between supervised and unsupervised learning. Supervised learning applied to seed systems ...

Seed Treaters - Case study
The Problem Having control over your operation is fundamental to running an efficient and profitable farm. This is true in all critical applications like planting, combining and marketing. And this is especially true when it comes to your seed treatment process – the growing season’s first opportunity to unlock maximum yield or suffer irreversible loss. We ...

Response of cultivars of race durango to continual dry bean versus rotational production systems
Continual dry bean (CB, Phaseolus vulgaris L.) production in the same field for 2 or more consecutive years is common worldwide. However, the effects on and performance of dry bean cultivars in the CB production system is not known. The objectives of this research were to (i) determine effects of the CB production system on seed yield, seed weight, and days to maturity of race Durango cultivars; ...

Why three Seed Treaters?
As farmers ourselves, we know each farming operation is unique. One size doesn’t fit all. So we set out address the needs of each and every farmer. We built all of our seed treaters from the ground up for fast, easy and accurate seed treatment on the farm. Each seed treater delivers the same great quality in terms of accuracy, seed coverage and gentleness. But there are some key ...

A Conceptual model for describing processes of crop improvement in database structures
Rising research costs, broadening goals, intellectual property rights, and other concerns increase the need for robust management of crop improvement data. The data model of the International Crop Information System (ICIS) allows breeding processes to be recorded unambiguously in a relational database. This paper describes this model, which underlies the Genealogical Management System (GMS) of ...

Safe seed-placed fertilizer practices and equipment limits
When it comes to applying seed-placed fertilizer, it is important to find the suitable application rate for each specific soil type and composition. But it is also important to understand that seeding equipment and technology is a factor, and may impact growers’ fertilizer rates. The seed-safe rate for fertilizers relies on numerous factors. Crop choice, soil composition, pH levels, ...

Organic and conventional production systems in the Wisconsin integrated cropping systems trial: ii. economic and risk analysis 1993–2006
This article, the second in a series looking at the Wisconsin Integrated Cropping Systems Trial (WICST), reports on the profitability of six conventional and organic systems, with a focus on net returns and associated risk exposure. Several pricing scenarios were compared to evaluate the impact of government programs and organic price premiums. When net return estimates are made using only ...

How `open source` seed producers from the U.S. to India are changing global food production
Around the world, plant breeders are resisting what they see as corporate control of the food supply by making seeds available for other breeders to use. Frank Morton has been breeding lettuce since the 1980s. His company offers 114 varieties, among them Outredgeous, which last year became the first plant that NASA astronauts grew and ate in space. For nearly 20 years, Morton’s work was ...

Evaluating exposure and potential effects on honeybee brood (Apis mellifera) development using glyphosate as an example
This study aimed to develop an approach to evaluate potential effects of plant protection products on honeybee brood with colonies at realistic worst‐case exposure rates. The approach comprised two stages. In the first stage, honeybee colonies were exposed to a commercial formulation of glyphosate applied to flowering Phacelia tanacetifolia with glyphosate residues quantified in relevant ...

Establishment and growth of self-seeded winter cereal cover crops in a soybean–corn rotation
Perpetuating cereal cover crops through self-seeding may increase adoption by reducing risk and cost. Winter rye (Secale cereale L.), wheat (Triticum aestivum L.), and triticale (x Triticosecale Wittmack) were used to develop self-seeding cover crop systems in a soybean [Glycine max (L.) Merr.]–corn (Zea mays L.) rotation. Cereals were planted and managed chemically and mechanically in varying ...

Getting seed to smallholders needs a business approach
A locally owned, alternative model of supplying affordable seed is working for Africa’s framers, says Joe DeVries. Smallholder farmers in Africa — mostly women — wage silent battles against the elements and other forces beyond their control to feed their families, their villages, their countries. They have historically taken the lead in feeding Africa and are destined to ...

Self-seeded cereal cover crop effects on interspecific competition with corn
Perpetuating cereal cover crops through self-seeding may increase adoption by reducing risk and cost. Winter rye (Secale cereale L.), wheat (Triticum aestivum L.), and triticale (x Triticosecale Wittmack) were used to develop self-seeding cover crop systems in a soybean [Glycine max (L.) Merr.]–corn (Zea mays L.) rotation. Cereal cover crops were planted in varying row spacing configurations and ...

Yield differences so large you can see them from outer space
When evaluating products, growers trust the results they see with their own eyes. The benefit of a different seed variety, irrigation system, fertilizing practice, new product, or method is suspect until the crop looks healthier and yields are higher. Growers remain skeptical until these technologies succeed in the climate and conditions of their region and in their own hands – because the ...

Seed Drying and Storage
SEED DRYING AND STORAGE The seed storage is usually in cold storage. The effectiveness of drying is the key to prolong storage life. Most seed-bearing plants will consider the room design with humidity control system which can make seeds tolerate the temperature; reduce the likelihood of germination, attacks by pathogens, insect infestation, discolouring and loss of freshness. 15 percent ...

Cover crop and nitrogen effects on maize productivity in no-Tillage Systems of the Brazilian cerrados
Cover crops in direct seeding mulch-based cropping (DMC) systems can be an effective tool to optimize N management for crop production in the Brazilian cerrados. The objective of this study was to determine the effect of four cover crops on maize (Zea mays L.) grain yields in two fields that had been under DMC for 3 and 14 yr. We hypothesized that cover crops would optimize N supply to the maize ...
