Effects of Terralyt - Plus® on soil pH, nutrient uptake and dry matter yield of maize
Acid soils are common in the tropics and managing them for sustainable cropping usually demands soil amendments. A greenhouse experiment was conducted at the Institute of Agricultural Research and Training, Ibadan, Nigeria to evaluate the effects of a soil amendment substance - organic biostimulator - Terralyt-Plus® on the growth, soil pH, nutrient uptake and dry matter production of maize. The soils...

Antimicrobial and antioxidant activities of essential oil and methanol extract of Jasminum sambac from Djibouti
The essential oil was subjected to screening for their possible antioxidant activity by two complementary test systems, namely DPPH free radical scavenging and β-carotene-linoleic acid assays. Butylated hydroxytoluene (BHT) was used as positive control in both test systems. In the DPPH test system, the IC50 value of essential oil and methanol extract were respectively 7.43 and 2.30...

Morphometric study of the genus Senna Mill. in South-western Nigeria
Thirteen quantitative characters of the leaves, fruits, seeds and flowers were used in the study of eight Senna Mill. species. The characters include leaflet length, leaflet width, leaflet length/width, Number of leaflets, lamina length, petiole length, pedicel length, petal length, fruit length, fruit width, fruit length/width, seed length and seed width. These characters were measured with the aid...

How fertilization affects yam (Dioscorea alata L.) growth and tuber yield across the years
This study deals with the response of Dioscorea alata to NPK-Ca fertilization as affected by differences in weather conditions in two growing seasons. Experiments were conducted in the central Côte d’Ivoire in 2006 and 2007. The experimental design was a randomised complete block design with 4 replications. The dose of 160-10-180-110 kg ha-1 of NPK-Ca, respectively was compared to...

Degradation of fungal cell walls of phytopathogenic fungi by lytic enzyme of Streptomyces griseus
In vitro tests of interactions between Streptomyces griseus strains and some soil-borne plant pathogens (Fusarium oxysporum, Alternaria alternate, Rhizoctonia solani and Fusarium solani) and 2 isolates of Aspergillus flavus were studied on PDA medium. Strains tested produced a metabolite that inhibited growth of plant pathogenic fungi on PDA medium (dual culture...

S1 selection of local maize landraces for low soil nitrogen tolerance in Zambia
Low soil nitrogen (N) limits maize production in Zambia. S1 selection was used to select for tolerance to low N among ninety-six maize landraces during 2004 - 2007 in Zambia. The landraces were evaluated under low N, drought and optimal conditions; and selfed in a nursery, under optimal conditions. Data on grain yield (GY), number of ears per plant, leaf senescence and anthesis-silking interval were used...
