Research ArticleOpen accessPhrase in the titleEvaluation of Inbred Lines and Hybrid Maize (Zea mays L.) for Tolerance to Striga hermonthica (Del.) Benth in the Guinea Savanna Agro-Ecological Zone of GhanaA. Bawa, M. S. Abdulai, I. K. AddaiThe study was conducted at the experimental field of the Savanna Agricultural Research Institute (SARI) to screen maize inbred and hybrid lines for Striga tolerance. Maize seeds of hybrid and inbred lines were collected from the West and Central African Maize Collaborative Network (WECAMAN), Boake, La Cote d’Ivoire, for the experiment. The experimental design used was the Randomized Complete Block … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 3 · 22 Sep 2015 · 7,788 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleNodulation 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 PDF Cite

Research ArticleOpen accessPhrase in the titleDiallel Analysis and Evaluation of Parents and F1 Progenies of Maize (Zea mays L.) for Tolerance to Drought and Striga hermonthica (Del.) Benth in the Guinea Savanna Agro-Ecological Zone of GhanaAlhassan Bawa, Isaac Kwahene Addai, Mashark Seidu Abdulai, Al-Hassan IssahakuField studies were conducted to evaluate 6 parents and 30 F1 hybrids of maize for tolerance to drought and Striga hermonthica in Nyankpala, Ghana during the 2014 and 2015 cropping seasons. These genotypes were evaluated for two years on single-row plots of three replicates, in a randomized complete block design. The control plants were planted in July each year which … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 1 · 25 Mar 2017 · 8,084 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Drought Stress on Growth and Yield of Soybean (Glycine max L.) Genotypes in Northern GhanaIsaac Kwahene Addai, Alhassan Bawa, Maganoba CharlesStudies on induced mutation were conducted and the results indicated that stable, but desirable soybean mutant genotypes with improved agronomic traits have been produced. A series of evaluations of these mutant genotypes had earlier on been carried out and high-yielding ones such as 150, 200, 250, and 300 Gy have been identified. In the present study, the above genotypes were … …American Journal of Agricultural and Biological Sciences, Vol. 18, Issue 1 · 1 Jun 2023 · 6,777 accessesView PDF Cite
