Research ArticleOpen accessIn the abstractNodulation and Biomass Yield Response of Cowpea to Row Spacing and Phosphorus Fertilizer Application in the Guinea Savanna Agro-Ecological Zone of GhanaAlhassan Bawa, Lukman YussifPhosphorus fertilizer application and planting distance play a major role in the production of shoot, root and nodule dry biomass of cowpea. However, phosphorus is a major limiting nutrient in soils in Ghana. Selection of cowpea varieties that produce good biomass yield under low soil phosphorus or those with high phosphorus response efficiency can be a low input approach in … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 4 · 23 Jan 2018 · 8,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Protection of Tomato Crops against Tuta absoluta in Open Ground Conditions in the South-East Part of KazakhstanA. Adilkhankyzy, K. A. Alpysbayeva, B. Nurmanov et al.There is a need to develop strategies for the protection of tomato crops that would provide high-quality produce safe for the consumer without environmental pollution. The objective of the study is to deploy an integrated system for the protection of open-field tomato crops from Tuta absoluta using biological agents (Bracon hebetor Say., Trichogramma, biopreparations, pheromone traps) and devices in the … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 16 Dec 2022 · 5,375 accessesView PDFCite
Research ArticleOpen accessIn the abstractParticipation of Dermacentor Reticulatus Imago in the Reservation of Bovine Leukemia VirusY. Glazunov, Ya. Kabitskaya, L. Glazunova et al.Strict implementation of measures for the prevention and elimination of bovine leukemia does not allow completely getting rid of this disease. In all likelihood, the leukemia virus has additional transmission routes that have not been taken into account until today. In the Tyumen region, blood-sucking insects and ticks are widespread and take part in the transmission of some infectious and … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 2 Nov 2022 · 5,074 accessesView PDFCite
