Economic assessment of some pre-emergence herbicides in the production of millet-cowpea intercrop in the Sudan Savanna Zone of Nigeria
Field trials were conducted in 1997 and 1998 cropping seasons at the University of Maiduguri Teaching and Research Farm located in Maduguri (11° 50’N; 13° 10’E). The aim was to carry out an economic analysis of the use of some pre-emergence herbicides for the production of millet-cowpea intercrop. The experiment consisted of 14 treatments which included four different herbicides at three rates each,...

Anti–diabetic studies of aqueous extract of Triplochiton scleroxylon on platelets and associated parameters in alloxan-induced diabetic rabbits
The effects of aqueous extract of Triplochiton scleroxylon (TS) on platelet and associated parameters, namely, platelet counts, volume and distribution width in alloxan-induced diabetic rabbits (New Zealand strain) were carried out. Plasma glucose concentration was also monitored as the test rabbits were treated with at least 100 ml of the aqueous extract daily through clean drinking troughs for a period of 28...

Establishing the basis for drought tolerance in maize (zea mays L.) using some secondary traits in the field
A field experiment was carried out from October 2009 to February 2010, to determine the drought tolerance levels of ten maize (Zea mays L.) genotypes and to establish a basis for the development of drought tolerant hybrids. The soil used belongs to theAsuansi series (Ferric Acrisol). Six inbred lines and four varieties with different genetic backgrounds were used. A total of 80 plots were prepared in the...

Drought response of some tropical rice genotypes: Rooting, vegetative traits and grain production
Sixteen upland rice varieties, comprising of some interspecific New rice for Africa (NERICA) hybrids, established varieties and some breeding lines, were raised in the greenhouse and used to expound drought response under varying moisture conditions, as a guide for breeding genotypes with appreciable drought tolerance and grain yield. Varieties were subjected to different levels of drought stress through different...

Effect of plant spacing on seed yield and yield components in kenaf (Hibiscus cannabinus) variety, Ifeken 400
Plant spacing required for optimum crop productivity depends on morpho-physiological traits between varieties, and the interaction between genotype and the environment. Studies were conducted in Ibadan (7°38’N 3°84’E) Nigeria, at the Institute of Agricultural Research and Training (IAR and T) during 2006 and 2007 to determine the influence of row spacing on seed yield in kenaf ...

Effects of organic and inorganic fertilizers on early growth characteristics of Khaya ivorensis Chev (African mahogany) in nursery
The effects of two inorganic fertilizers (urea and super phosphate simple) and organic manure (fowl droppings) on the early growth of seedlings of Khaya ivorensis in nursery were investigated using ten nutrient treatments, nine of which were nutrient combinations and one, a negative control. Urea was added at 0.75 and 112.50 mg while super phosphate simple (SPS) was added at 0.30 and 60 mg. Changes in plant...

Quantities and values of selected forest medicines harvested by eight villages adjacent to natural woodlands in the four ecological zones of rural Swaziland
Harvesting patterns of non-timber forest products (NTFPs) normally vary within and between communities and villages adjacent to natural woodlands. The objective of this study was to undertake user surveys to determine the actual quantities of harvested and utilized medicinal NTFPs, and to do an economic valuation of their direct use values. Methods used included literature research, community consultations, household...

Morpho-anatomical variation in some accessions of Moringa oleifera Lam. from Northern Nigeria
Variations in the leaf morphological and anatomical features of Moringa oleifera Lam. accessions from Northern Nigeria have been reported. The wide range of uses of this naturalised crop in Nigeria has in recent time witnessed increasing demand of its foliar product in nutritional, medical and ecological applications. The upsurge demand for this product needs to be balanced with new lines...

Evaluation of cumin (Cuminum cyminum L.) landraces under drought stress based on some agronomic traits
Cumin (Cuminum cyminum L.) is a herbaceous and medicinal crop which is one of the most important export crops for countries such as Iran. This study was conducted to study the effects of drought stress on agronomic traits in cumin landraces of Iran. This experiment was conducted in simple lattice design, with two replications in drought stress and non-stress conditions. Nine land races (49 sub landraces) from...
