Effects of fungicide application and different nitrogen fertilizer levels on yield components of three varieties of common bean Phaseolus vulgaris L.
In Cameroon, common bean is produced and highly consumed as a source of protein and means of generating income by small farm holders. However, diseases like angular leaf spot caused by Phaeoisariopsis griseola (Sacc), poor agronomic practices and low soil fertility are negatively impacting the production of the crop. A field experiment was conducted under natural conditions in the University of Dschang during the 2017...
Exploring the induction of doubled haploids in cassava through gynogenesis
Production and use of double haploids is important for attainment of systematic genetic gains, and indeed several plant breeding programmes have benefited from it. Gynogenesis, the in vitro culture of unfertilized ovules and/or embryos has specifically been exploited in several economically important crops but not cassava. In this study, we examined possibilities of generating doubled haploids (DH) in cassava...
Gas exchange in upland cotton cultivars under water deficit strategies
Aiming to evaluate the gas exchange of upland cotton cultivars cultivated in the Brazilian semiarid, subject to water deficit periods on the phenological stages, an experiment was carried out at the Campina Grande Federal University, Pombal county campus, Paraíba State, Brazil, between June and December 2015. Treatments were formed from a split-plot arrangement, in which the plots were 6 water deficit periods (P)...
Fiber quality in upland cotton cultivars under water deficit strategies
An evaluation was made of upland cotton cultivar fiber quality, when subjected to water deficit periods, on the phenological stages. The experiment was carried out at the Campina Grande Federal University, Pombal county Campus, Paraíba State, Brazil, between June and December 2015. Treatments were formed using a split-plot arrangement, in which the plots were 6 water deficit periods (P) (P1 = No deficit; P2 =...
