Food insecurity and HIV/AIDS as it affects women in Nigeria

HIV/AIDS, poverty and agriculture all have effects on the women in the African culture, based on the fact that the activity of the women in agriculture and the yield cannot translate to food sufficiency and provide a means of lively hood for her and her children thus leading to the incidence of poverty. It is believed that the men folks, the low level of agricultural productivity, family dependence and poor...

Effect of urban wastewater usage and problems of accumulation of heavy metals in agricultural lands (south of Tehran)

Cultivation of plants as sources of human food and livestock around the big cities like Tehran is common. In some of these areas, untreated raw sewage and urban wastewaters are used for irrigation of these plants. In Southern Tehran, the long-term irrigation of plants with waste water is produced by urbanactivities, regardless of the increase of soil fertility and the provision of macro and micro nutrients, such...

Modelling the effect of supplementing elephant grass with lablab and desmodium on weight gain of dairy heifers under stall-feeding system

This study reports on a simulation growth model developed to predict daily gain (DG) of dairy cattle heifers. The model input parameters are gross energy (GE), ash, crude protein (CP), organic matter digestibility (OMD), dry matter (DM), protein degradation variables and heifer initial body weight. Results from the simulation model show that at low levels of CP in elephant grass (Pennisetum purpureum) there is improved...

Effect of sowing date on Striga infestation and yield of sorghum (Sorghum bicolor [L.] Moench) cultivars in the Sudan savanna of northeast Nigeria

Striga hermonthica is a serious biotic constraint to sorghum production in the dry savannas of sub-Saharan Africa but the use of improved cultivars and appropriate planting dates may help to control the weed. A two year trial was conducted to evaluate the effect of sowing dates on four sorghum cultivars (improved: ICSV111, ICSV400, KSV8, and landrace: HANUNGIWA) under natural infestation with S....

Yield response and stability among cowpea genotypes at three planting dates and test environments

Cowpea (Vigna unguiculata (L.) Walp.) is one of the important food legumes and a valuable component of the traditional cropping systems in the semiarid tropics. Its productivity is generally low since farmers still grow unimproved landraces as a result of unavailability of improved and locally adapted cultivars. The objective of this study was to determine the relative yield response and stability among selected...

Chemical control of invasive Psidium guajava in Swaziland: A preliminary assessment of costs and efficacy

Psidium guajava (guava) is recognised as the third most important inva­sive alien plant species in the moist savanna biome of South Africa, Lesotho and Swaziland. The cost of initial clearing of alien plants reaches up to R3 000-00 per ha, therefore the application of correct control methods is essential for cost-effective reduction of the spread. The aim of this study was to test the cost...

Application of kriging and cokriging in spatial estimation of groundwater quality parameters

    Excessive use of groundwater aquifers may result in low quality groundwater. The chloride content and the sodium adsorption ratio (SAR) are among the most important water quality parameters, that is, the estimation of these two parameters and, consequently, Na+, Ca2+ and Mg2+ concentration are much more time-consuming and expensive than water salinity measurement. Thus, it seems...
