MSc-thesis presentation Stefanie Pflug

On 29 May 2013, Stefanie Pflug presented the results of her research conducted at Wageningen University, the Netherlands. In her experiments she studied the interaction between the parasitic weed Rhamphicarpa fistulosa and its host rice (Oryza sativa). The research focussed on two aspects of the host-parasite interaction: 1) The influence of host plant size, developmental stage and parasite size on growth of both

Willingness of farmers to adopt rice intercrops in Uganda

Stella Kabiri has co-authored a publication that analyses the willingness of farmers to adopt rice intercrops in the Lake Victoria Crescent Agro-ecological Zone of Uganda. Paper summary In Uganda we found that upland rice farmers spent more time cultivating rice, an income crop that is labour intensive, at the expense of other food security crops. The problem was that when rice failed

Jonne Rodenburg on “Uprooting underground killers”

Parasitic weeds of the genus Striga—also known as witchweeds—are a major threat to upland rice production in several parts of Africa. The roots of Striga seedlings penetrate the root cells of host plants, among them, rice, and leave them weak and unproductive. AfricaRice and its partners are making significant headway in the struggle to control Striga in rice fields across

Lunch seminar CSA Marc Schut

Postdoc Marc Schut gave a CSA lunch seminar entitled: "Analysis of agricultural innovation in crop protection and extension systems in Tanzania: The case of parasitic weeds in rainfed rice production systems." In the seminar he discussed how he operationalised the Agricultural Innovation Systems approach to study the institutional and political dynamics of parasitic weeds in rainfed, smallholder rice production systems

MSc-research and colloquium Djoeke Langeloo

In January 2012 I started my MSc thesis research within the Parasite Programme. My research focussed on the reproductive success of the parasitic weeds Striga asiatica and Rhamphicarpa fistulosa. In particular, I explored how the reproductive success was affected by different rice sowing dates, rice varieties and parasitic weed seed densities. The first two aspects were studied in two field

Innovation Systems paper Klerkx and Schut published in IDS-bulletin

A paper authored by Parasite project members Laurens Klerkx and Marc Schut has been published in IDS bulletin. Abstract The process of knowledge brokering in the agricultural sector, where it is generally called agricultural extension, has been studied since the 1950s. While agricultural extension initially employed research push models, it gradually moved towards research pull and collaborative research models. The

Rhamphicarpa, a growing problem

Please check out this article in Plant Life, news letter on plant sciences of Wageningen UR in which Lammert Bastiaans sheds his light on the growing problems of Rhamphicarpa in different parts of Africa. A major parasitic plant that is thriving in relatively humid low-lying countries in Africa is Rhamphicarpa fistulosa. Rhamphicarpa fistulosa is at home in boggy fields where it finds
