Sowing density effect on common bean leaf area development

Autor: Ricaurte Oyola, José Jaumer Clavijo Michelangeli, Jose A. Sinclair, Thomas R. Rao, Idupulapati M. Beebe, Stephen E.

Sowing density is a major management factor that affects growth and development of grain crops by modifying the canopy light environment and interplant competition for water and nutrients. While the effects of sowing density and plant architecture on static vegetative and reproductive growth trai...

Effective use of water and increased dry matter partitioned to grain contribute to yield of common bean improved for drought resistance

Autor: Polanía Perdomo, José A. Poschenrieder, Charlotte Beebe, Stephen E. Rao, Idupulapati M.

Common bean (Phaseolus vulgaris L.) is the most important food legume in the diet of poor people in the tropics. Drought causes severe yield loss in this crop. Identification of traits associated with drought resistance contributes to improving the process of generating bean genotypes adapted to ...

Cassava leaf harvesting as vegetables: a cause of vulnerability of cassava plants to cassava mosaic disease and eventual yield reduction

Autor: Ariyo, O.A. Dixon, Alfred G.O. Atiri, G.I.

The consequence of harvesting young leaves of cassava as vegetable on the vulnerability of the crop to cassava mosaic disease (CMD) and on storage root yield was investigated using 30 cassava genotypes planted in IITA fields located in the humid forest (Port Harcourt : Onne), forest-savannah tran...

Comparative effects of explant source and genotype on in vitro tuberization in Dioscorea alata and D. rotundata

Autor: Balogun, M.O. Ng, S.Y. Shiwachi, H. Ng, N.Q. Fawole, I.

Single node cuttings of two genotypes each of Dioscorea alata and D. rotundata from both plants grown in screen houses and in vitro plantlets were cultured in a tuberization medium. The screen house explants had significantly higher plantlet tuberization and primary nodal complex formation, and m...

Improving adaptation to drought stress in white pea bean (Phaseolus vulgaris L.): Genotypic effects on grain yield, yield components and pod harvest index

Autor: Assefa, Teshale Rao, Idupulapati M. Cannon, Steven B. Wu, Jixiang Gutema, Zenbaba Blair, Matthew W. Otyama, Paul Alemayehu, Fitsume Dagne, Belete

Common bean (Phaseolus vulgaris L.) is the most important food legume crop in Africa and Latin America where rainfall pattern is unpredictable. The objectives were to identify better yielding common bean lines with good canning quality under drought, and to identify traits that could be used as s...

Management of African root and tuber scale using improved cassava genotypes and mineral fertilizers

Autor: Lema, K.M. Tata-Hangy, K. Bidiaka, M.

The African root and tuber scale (ARTS), Stictococcus vayssierei Richard, is an insect species indigenous to Africa, which has recently become an economic pest of cassava (Manihot esculenta Crantz) in many parts of the Democratic Republic of the Congo (D R C). This scale infests underground parts...

Genotype x environment interaction effects on native cassava starch quality and potential for starch use in the commercial sector

Autor: Benesi, I.R.M. Labuschagne, M.T. Dixon, A. Mahungu, N.M.

Cassava (Manihot esculenta Crantz) is the second most important staple food crop in sub-Saharan Africa, providing up to 285 calories per person per day. Cassava starch is a potentially important industrial material in Malawi. Industries hesitate to use cassava starch because the powder sold by so...
