The allelopathic effect of different species of grapevine berries aqueous extracts on some germination parameters of lettuce (Lactuca sativa L.) seeds
Allelopathic potential of twelve local varieties of grapevine Vitis vinifera fruits: taefi; zareg-dohuok; Baetmuni; Black-manga; Sarqala-bakrajo; Awelka; Rash-merii; Mala-Hassan; Ashgar-basraha; Kamalii; Toli-mawelian and Shekh-nuraddin on some germination and growth parameters of lettuce seeds Lactuca sativa has been investigated . The aqueous extracts caused significant inhibitory effects on germination rate; germination speed; radical length; plumule length; […]
Effect of aqueous extracts of Chrozophora obliqua (Del.) Juss. on germination and seedling growth of Zea mays
The allelopathic influence of aqueous extracts of Chrozophora obliqua (Del.) Juss. on the germination and seedling growth of Zea mays have been determined. It was noted that 10g aqueous extracts of leaves and 48hr treatment present significant inhibitory effect on germination, radical length and number of seminal roots and the effect was found significantly higher […]
Deterioration of maize seeds (Zea mays L.) during storage: Evaluating quality components of grains under conservation
In tropical Africa, several vulnerable communities are facing seed insecurity, impairing food security. The conservation, good management, and maintenance of seed quality are thus major issues in seed security, especially since the quality of the latter is altered over time. It therefore becomes interesting to conduct research on the evolution of seed deterioration during storage. […]
Phenotypic evaluation of six cassava families (Manihot esculenta Crantz) from seed in Burkina Faso
Phenotypic markers are important in plant genetic characterisation studies. They are used in the present study to assess the phenotypic structuring of cassava genotypes obtained by biparental crossing. The plant material studied consists of 56 cassava genotypes from the third generation of vegetative reproduction following germination of seeds from six families resulting from crosses. To […]
Effect of sowing dates on the growth and seed production of okra [Abelmoschus esculentus (L.) Moench] during the off-season in Burkina Faso
Okra is a widely cultivated traditional vegetable in Burkina Faso. Its fruits are rich in micronutrients, vitamins, fiber, and mucilage, making it an essential dietary supplement. Despite its potential, okra cultivation faces challenges due to the limited availability of quality seeds. This study aimed to identify optimal sowing dates for producing high-quality okra seeds in […]
Influence of amendment type and re-cutting on biomass production and germination capacity of Artemisia annua L. in Burkina Faso
Artemisia annua L. is a plant containing artemisinin in its leaves, recommended by the world health organization (WHO) for the treatment of malaria through Artemisinin-based Combination Therapy (ACT). This study was carried out to develop an efficient technique for producing aerial biomass and seeds with high germination capacity of the species. A factorial block design […]
Genetic variation in physiological seed quality of some selected cowpea genotypes
The study was conducted using fifteen cowpea genotypes evaluated for their physiological seed quality attributes using viability and vigour tests. The laboratory experiments were set-up in a complete randomized design with three replicates at the seed quality control unit of the Institute of Agricultural Research and Training, Ibadan, Oyo State. Data collected were subjected to […]
Propagation of Pterocarpus erinaceus Poir. seeds from four vegetation zones of Nigeria, using different pre-sowing treatments and sowing media
Pterocarpus erinaceus Poir. is a tree species of the family Leguminonaseae distributed across West and Central Africa. The surging demand for its wood has hampered its natural regeneration in Nigeria. Effects of pre-sowing treatments and soil media on the germination of its seeds were examined using stratified random sampling. Seeds were sourced from Guineo-Sudanian savanna, […]
Interaction Effect of Blended (NPSB) Fertilizer Rates and Seed Sources on Yield Components and Seed Quality of Bread Wheat (Triticum aestivum L) Varieties in Southern Ethiopia
Low soil fertility and poor quality seed sources are the major yields and seed quality limiting constraints of bread wheat in Ethiopia. Therefore, a field experiment was conducted in Doyogana district during the 2020 cropping season to determine the interaction effect of blended fertilizer rates and seed sources on the yield and seed quality of […]
Effect of Blended NPSZn fertilizer and Variety on quality of Carrot (Daucus Carota L.) Seed at Hossana, Southern Ethiopia
Carrot is an important vegetable crop in Ethiopia. However, the quality of the crop is low mainly due to low soil fertility and a lack of improved varieties resulting in low yield and low quality of carrot seed. Therefore, this study was conducted in 2019 to assess the effect of blended NPSZn fertilizer and to […]
