In de plantenveredeling vindt op dit moment zeer snelle innovatie plaats. Een deel van deze innovatie is onderdeel van een maatschappelijk debat. Dit dossier bevat lesmateriaal om nieuwe wetenschappelijke kennis en inzichten door te laten stromen naar verschillende niveaus in het Groene onderwijs. Ultiem doel is jongeren zodanig van kennis te voorzien dat zij zelf een goed onderbouwde mening kunnen formuleren over kansen en risico’s van gebruik van nieuwe technieken in de veredeling, en daarmee ook een bijdrage kunnen leveren aan genoemd maatschappelijk debat.
Strokenteelt klaar voor de praktijk : aardappel drie tot tien dagen later branden

Na de eerste verkenningen met het telen in stroken zijn onderzoeken naar de effecten ervan verder uitgebreid. Inmiddels zijn er meerdere strokenproeven verdeeld over vier locaties – Droevendaal, ERF, De Graanrepubliek en NZ27 – en zijn de verwachte voordelen van dit teeltsysteem bevestigd. Afhankelijk van de inrichting van het bedrijf en aansluitende mechanisatie lijkt strokenteelt klaar voor de praktijk.
Duurzame beheersing van phytophthora : Resistentiemanagement blijft noodzakelijk
Pacilly, F.C.A. - \ 2017

De Wageningse promovenda Francine Pacilly doet onderzoek naar phytophthorabeheersing. Ze ontwikkelt een computermodel waarmee je kan onderzoeken wat het effect is van bepaalde maatregelen. Afgelopen winter is het model getest met hulp van biologische en gangbare aardappeltelers. In dit artikel meer achtergronden over het model en de ervaringen uit de workshops met de telers.

Jatropha curcas L. is a biofuel crop that has not lived up to expectations due to a combination of hype and disappointment and biophysical factors. This PhD thesis is based on the plant production component of the JARAK programme which aimed to bridge the gap between truth and fiction. This study reviewed the jatropha hype and disappointment and further investigated the hypothesis that jatropha growth and yield are limited by biophysical factors of plant characteristics, cropping systems, and management. My review of the hype and disappointment shows that despite the high expectations fuelled by market pull and technology push, and numerous actors, the commercial potential for jatropha is limited by policy and governance, economics, social, technology, logistical, and environmental. A study of the biophysical components confirms that no current varieties suited to different cropping systems and locations are available. Jatropha aboveground biomass is partitioned predominantly into a structure of stem, branches, and twigs. The below to aboveground biomass ratio was 0.5 and fruit which was found only on productive twigs accounted for the smallest portion of biomass measured. Seed yields were disappointingly small (109 kg ha-1) and were largest in monoculture, followed by intercropping and hedgerows in that order, although yields were influenced by age and management of pruning and fertiliser. Seed yield across the three cropping systems can be predicted using plant height and the number of productive twig/branch, although the number of inflorescence clusters per productive twig may be important. Intercropping between jatropha and maize (Zea mays L.) resulted in competition for resources both belowground and aboveground that reduced maize yields. Shoot pruning was effective in managing aboveground competition, while root pruning and root barriers effectively managed competition belowground. Leaf prunings provided a limited, but positive fertility effect on maize yield comparable to 21 kg N ha-1. Jatropha - maize intercropping has potential for long-term productivity provided management practices such as fertiliser, pruning, and planting density can be developed to minimise competition and enhance complementarity. Based on my review of the jatropha hype and disappointment and my biophysical research results, the planting of jatropha by smallholders, or as a plantation crop cannot be recommended. Once the issues I highlight have been resolved and market confidence restored, jatropha may finally become a commercial source of biodiesel able to provide improved socio-economic and environmental benefits.
