In many parts of India intensive cultivation of safflower on Vertisols appears to have aggravated the problem of Fusarium wilt in safflower due to the soil borne fungus, Fusarium oxysporum Schlecht f. sp. carthami Klisiwiez and Houstan (FOC). In a long-term field experiment at Patancheru, India, ...

This paper reports the occurrence of bacterial leaf streak (Xanthomonas campestris pv. holcicola [Xanthomonas vasicola pv. holcicola]) on sorghum (Sorghum bicolor) at the ICRISAT research farm, Andhra Pradesh, India and in several farmers fields in Karnataka in 1999-2001. Disease symptoms were sm...

Infestation of cereals and cowpeas by Striga species constitute a major constraint to increased crop productivity in the savannas of northern Nigeria. Field surveys were undertaken in Jigawa State, Nigeria in 2012 to assess (i) the level and extent of Strgia infestation of cereal and cowpea field...

Aflatoxins are a common contaminant of cereals that can cause cancer, liver disease, immune suppression, retarded growth and development, and death, depending on the level and duration of exposure. Maize is an introduced crop to Africa and there have been efforts over the last 20 years or so to r...

A series of trials was conducted to quantify response of dry season transplanted sorghum to water and fertilizer application in order to test the hypothesis that soil moisture limits production more than nutrient supply. The trials were conducted at two field sites representative of a large land ...

The residual effects of winter-sown forage mixtures grown in the northern rainfed parts of Punjab province and south-eastern North West Frontier Province in Pakistan were examined. Studies were carried out during 1994–97 primarily at the National Agricultural Research Centre (NARC), Islamabad, wh...

West Africa (WA) is among the most food insecure regions. Rapid human population growth and stagnating crop yields greatly contribute to this fact. Poor soil fertility, especially low plant available phosphorus (P) is constraining food production in the region. P-fertilizer use in WA is among the...

The effect of the environment on the germination, survival and infection of sorghum by conidia of Peronosclerospora sorghi is unknown in Africa. Dew point temperature, and the effect of conidium age was characterized for an isolate of P. sorghi from Zimbabwe. Germination and germ tube growth took...
