The main objective of this study was to determine the level of participation of rural women in Community and Social Development Project (CSDP), a Community Driven Development Project in Kogi State, Nigeria. Purposive sampling technique was used to select eight communities from four Local Government Areas of the State, while simple random sampling t... Continue Reading
The relationship between topography, soil and vegetation in the Northern Guinea ecosystem of Nigeria has been investigated. The results of the investigations revealed a strong inter, action between topography, soil development and both the species distribution and the general vegetation growth performance- Soil depth increased down the slope. Soil... Continue Reading
Productivityof groundnut has been generally low in Nigeria owing to soil fertility problems arising from low soil pH and low organic matter content of the soils leading to deficiency of major nutrients, especially, N and P. Current fertilizer recommendations are based on single nutrient trials and do not take into consideration the use of lime, man... Continue Reading
Laboratory studies were conducted in the Entomology Laboratory of Crop Protection Department, Institute for Agricultural Research, Ahmadu Bello University, Samaru-Zaria, to evaluate the efficacies of four silica-based dust namely; Diatomaceous earth (DE), Periwinkle shell dust (PSD), Rice husk ash (RHAC), and Prawn shellash (PSA) with Pirimiphos m...

Soil quality protection under intensive land use and fast growing economic development has become a major challenge for sustainable resource use in developing countries such as Nigeria. Continue Reading
The effectiveness of various herbicide treatments for season-long control of weeds in three cultivars of rice (Oryza sativa L) was investigated in 1983 wet and 1983-84 dry seasons at Badeggi (09ÂÂ� 45'N and 06ÂÂ� 30'E,, 70.5m above mean sea level) in the Southern Guinea Savanna ecological zone of Nigeria.

The study was set out to estimate heterosis, combining ability, heritability, gene action and correlation of grain yield and other agronomic traits under water stress and non-water stress conditions. Seven maize varieties were crossed to six inbred lines resulting in 42 top cross hybrids. The 13 parents, 42 hybrids and a check were evaluated for dr... Continue Reading

Field surveys were conducted during the 2016 dry season in three Local Government Areas in Sokoto and Zamfara States of Nigeria to determine the occurrence, distribution and alternative hosts of viruses of tomato [Solanum lycopersicum (L.)]. A total of 18 tomato farms were surveyed in the two States, 9 in each of the States. Sampling was done in f... Continue Reading
Two feeding trials were conducted to evaluate the nutritional value of Roselle seed fermented at varying durations in the diet of broiler chickens on growth performance, carcass chararacteristics, haematological parameters and nutrient digestibility. Experiment one involved Roselle seed fermented at varying durations, while in experiment two Rosel... Continue Reading
Sorghum [Sorghum bicolor (L.) Moench] is a cereal belonging to the family Poaceae.Sorghum is an important staple food crop in northern Nigeria. Most Sorghum, varieties especially white endosperm colouredvarietieshave low pro-vitamin A (PVA) content compared to some yellow endosperm varieties leading to PVAmalnutrition on populations who depend on t...

The present study illustrates the effect of topography on soil formation and distribution on basement complex rocks of Northern Guinea Savanna of Nigeria. Six landforms were identified through the processing of satellite images namely; Tableland with very high relief, irregular plains with some moderate relief, smooth plains with some moderate rel...
