Kolanut production, processing and marketing in the South-eastern states of Nigeria
Kolanut is an important economic crop in the South Eastern region of Nigeria. However, there were no contiguous kola plantations in the South East, rather each homestead has about 2 to 15 kola trees scattered around the backyard. The land tenure system was observed to be the major constraint to kola production in large scale in the South East. Other limiting factors were poor nutrient status of the South Eastern soils,...

Importance of knowledge of chemical composition of stem bark of Triplochiton scleroxylon K. Schum. in traditional treatment of diabetes mellitus in Nigeria
Triplochiton scleroxylon is a tropical forest-tree species that is valued for its timber and also stem barks, whose aqueous extract is commonly used as an anti-diabetic preparation. Stem bark extracts (aqueous and 50% ethanol) and powder of T. scleroxylon were investigated for elemental and proximate compositions. Atomic absorption spectroscopy (Buck Scientific VGP 210) was used for elemental analysis....

Micro-mineral contents in eight forage shrubs at three phenological stages in a Pakistan’s rangeland
Livestock rearing is a common practice in Gadoon Hills by the locals to earn their livelihood. Low productivity due to poor health of livestock is major consideration in the study area. In order to know whether this low productivity and poor health might be due to poor quality of forage, eight shrubs, namely, Berberis lycium, Debregeasia salicifolia, Dodonea viscosa, Gymnosporia royleana, Indigofera heterantha,...

Assessment of soil quality under various land use practices in a humid agro-ecological zone of Nigeria
In this study, soil samples were collected from 0 to 15 cm and 15 to 45 cm of secondary forest, mixed plantation, natural fallow and sole plantation. Soil samples were chemically analyzed using standard methods for organic matter, nitrate-nitrogen, pH, bulk density and available phosphorus. The results were statistically analyzed and index of deterioration was also calculated for the soil properties. Mixed plantation...

Evaluation of cowpea cultivars under maize and maize-cassava based intercropping systems
A field experiment in a randomized complete block design with three replications was conducted at the research farm of the Institute of Agricultural Research and Training, Moor Plantation Ibadan, Southwest Nigeria in 2003 and 2004 cropping seasons. The aim of the experiment was to evaluate five cowpea cultivars; IT89KD-288, IT96D-610, IT99K 1060, IT95K-1072-57 and Ife Brown under sole, maize-based and maize-cassava...

Effects of foliar application of salicylic acid on vegetative growth of maize under saline conditions
The study was carried out to evaluate the effects of foliar application of salicylic acid (SA) on vegetative growth of maize under saline conditions at Rafsanjan, Iran in 2009. A factorial experiment based on a completely randomized design with three replicates was used. Treatments consisted four salinity levels (0, 4, 8 and 12 dS/m) and three salicylic acid concentrations (0, 100 and 200 ppm)....

Split crown technique for mass propagation of smooth Cayenne pineapple in South-South Nigeria
A study was conducted to investigate the effect of apical meristem destruction on axillary bud growth of smooth cayenne pineapple in South-South Nigeria. Split crown technique (SCT) was used for the study in a randomized complete block design with four replicates and four treatments. The number of days to sucker emergence from the axillary buds were significantly different among the treatments ranging from 36.6 days to...

Effects of gibberellic acid on sugarcane plants exposed to salinity under a hydroponic system
A hydroponical experiment was conducted to evaluate the possible interaction of salinity (EC 0 and 9 dSm-1) and occurrence of exogenous gibberellic acid (GA3) (100 ppm) on imbalance and partitioning of nutrients in a popular sugarcane genotype (var. CP48-103) and its somaclonal tolerant variant. The results revealed that the uptake and partitioning of N, K+, Na+ and Cl- content were affected as a result of...

Survey of plant parasitic nematodes associated with rice (Oryza sativa L.) in South Eastern Nigeria
The presence and population of plant parasitic nematodes associated with rice cultivation was determined at the rice cultivation zone of Ini Local Government Area of Akwa Ibom State, through a survey. Samples of plant roots and soil were randomly collected for the presence of nematodes while extraction was conducted using Pie Pan Modification of the Baerman funnel method. The results showed the presence of three genera...

Effect of seed soaking treatment with growth regulators on phytohormone level and sex modification in cucumber (Cucumis sativus L.)
Field experiments were undertaken at national agricultural research centre Islamabad, Pakistan during 2004 and 2005 to study the seed soaking effects of 2-chloroethylphosphonic acid (ethrel), gibberellic acid and maleic hydrazide (MH) on sex modification in cucumber and to find out the critical phytohormones level of endogenous hormones for lowest sex ratio. Seeds were soaked in different concentrations of growth...

Investigation of genetic relationship among yellow mosaic virus resistant cowpea lines by using microsatellite markers
Microsatellite markers were used to investigate the genetic basis of cowpea yellow mosaic virus (CYMV) resistance in 40 cowpea lines. A total of 60 simple sequence repeat (SSR) primers were used to screen polymorphism between stable resistance (GC-3) and susceptible (Chrodi) genotypes of cowpea. Among these, only 4 primers were polymorphic and these 4 SSR primer pairs were used to detect CYMV resistant genes among 40...
