Abstract

Field experiments were conducted at the Teaching and Research Farm of Faculty of Agriculture, Bayero University, Kano (Latitude 120 03'N and Longitude 80 32'E) and Jigawa State Research Institute Farm, Kazaure (Latitude 120 06'N and Longitude 8047 E) in 2015 rainy season. The study was aimed to evaluate the effects of Parkia biglobosa fruit powder in the control of Striga (Striga gesnerioides (Walp) Vatke), growth and yield of cowpea (Vigna unguiculata (L.) Walp) under field condition. The treatments consisted of three methods of Parkia fruit powder application (seed coating, basal and the control) and seven cowpea varieties (IT90K-277-2, IT97K-205-8, IT97K-390-2, IT97K-461-4, IT97K-568-11, IT98D-288, IT98K-131-2 and IT03K-378-4). These were laid in a split plot design and replicated three times. Methods of application of Parkia fruit powder were assigned to the main plot, while cowpea varieties were in the subplot. Results of the study showed that the control plots had the highest Striga count m-2 in both locations. The variety IT90K-390-2 recorded the highest number of Striga m-2 (5.11) while 1T97K-205-8 had none. Among the varieties tested, IT90K-277-2 recorded the highest grain yield (1841.3 kg ha-1) while IT03K-378-4 had t...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
