Striga hermonthica (L) Moench, a parasitic weed species, is a major constraint to sorghum production in the savanna zones of north-eastern Nigeria. The aim of this study was to assess the influence of farmer practices on Striga infestation of sorghum fields in the region. Random sampling techniqu...
Striga gesnerioides is considered a major constraint to improving cowpea productivity in the semi arid region of Africa. A field survey was conducted in a farmer participatory process in 100 cowpea fields to determine farmers’ crop production practices that influence infestation by the parasitic ...

Striga hermonthica parasitism is a major constraint limiting Sorghum productivity in the Nigerian savanna. Field experiments were conducted in 2005 and 2006 rainy seasons to evaluate the response of sorghum varieties to striga infestation. A randomised complete block design was used to screen 12 ...

The cultivation of soybean is increasing in the savannas of Nigeria due to its widespread use in the food and feed industry. Production is, however, constrained by low soil phosphorus (P) levels in northeast Nigeria. This study evaluated four soybean varieties for their response to three rates of...

The goal of this research was to evaluate diverse cowpea genotypes developed over the past 4 decades in the Nigerian
Sudan Savannas for their agronomic performance and to identify groups of cultivars with similar quantitative characters.
Characterization would facilitate the efficient synthesis o...

Soybean can contribute to soil N, which may partly be used to improve maize production in northeast
Nigeria. However, the efficiency of soybean to fix N can be limited by soil P deficiency. This study
evaluated the effect of P application and soybean cultivars on dry matter and grain yield of sub...

Groundnut production in northeast Nigeria is constrained by low level of soil phosphorus. This study evaluated four groundnut varieties for their response to P fertilization in two Nigerian agro-ecological zones (Sudan and Northern Guinea savanna) during 2005 and 2006. The experimental design was...

The aim of this study was to assess the influence of farmers` crop management practices on Striga infestation and maize grain yield. Sixty farmers` fields were randomly selected in nine communities across three savanna zones. About 35% of the farmers had cultivated their fields for over 10 years,...
