In many traditionally managed agroecosystems, populations of domesticated plants maintain high levels of genetic diversity. The threat of erosion of this diversity is a current conservation concern, motivating studies of how diversity can be maintained by in situ conservation measures. Precisely ...

One low cost and two premium type sorghum stover purchased from fodder market in Hyderabad, India were investigated for Organic matter intake (OMI), organic matter digestibility (OMD) and organic matter intake and digestible organic matter intake (DOMI) with feeding trials on sheep. The average p...

This project is designed to develop in a farmer-participatory manner pearl millet [Pennisetumglaucum (L.) R. Br.] and sorghum [Sorghum bicolor (L.) Moench] populations or cultivars with specific adaptation to different production environments in Niger, Mali and Burkina Faso. It consists of two su...

Striga is a major constraint to crop productivity in the savanna zones of northeast Nigeria. In a community livelihood survey, farmers in the region ranked Striga infestation as the topmost priority constraint. A field survey was, therefore, conducted to assess the level of field infestation by S...

Infestation of cereals and cowpeas by Striga species constitute a major constraint to increased crop pro-ductivity in the savannas of northern Nigeria. Field surveys were undertaken in Jigawa State, Nigeria in2012 to assess (i) the level and extent of Strgia infestation of cereal and cowpea field...

Traditional and improved varieties of maize, pearl millet and sorghum were planted by small-scale farmers under the direction of the International Institute for Tropical Agriculture in two Nigerian agro-ecological zones: the Sudan Savanna and the Northern Guinea Savanna. Samples were collected fo...

Basing dual-purpose sorghum genetic improvement work on untested laboratory traits could clearly present uncertain results for the breeding objective. In that context, this study compares a wide range of chemical (nitrogen, fiber constituents neutral detergent fiber (NDF), acid detergent fiber (A...

Nine isolates of Peronosclerospora sorghi from maize, sorghum and wild sorghum were sampled from Zimbabwe, Zambia, Rwanda, Mozambique and Kenya. They were compared for variation in conidium and conidiophore morphology, temperature requirements for sporulation, germination and germ-tube growth and...

Sorghum ergot in India is caused by Claviceps africana and C. sorghi. The distributions of these two species in India is not known. Eighty-nine sorghum ergot isolates were cultured from young sphacelia obtained from male sterile sorghum plants artificially inoculated using inoculum collected in t...
