Replication data for: Impact of organic soil amendments on physical characteristic and yield components of Solanum tuberosum
No full textA field experiment was conducted in the western Highlands of Cameroon to study the effect of Calliandra calothyrsus, compost manure and mineral fertilizer. A two factorial treatment combination made up of fertilization schemes and sanitary measures were laid out in randomised complete block design with four replication resulting to 10 treatments. data collected on physical characteristics, yield component and potatoes late blight severity were subjected to multivariate ANOVA and means seperated with the dunnet (t-test) with Calliandra calothyrsus considered as the focus amendments. Result obtained revealed significant effect of fertilization schemes on the growth charateristics and yield component of potato. For stem diameter, plants under Calliandra calothyrsus surpassed significantly all the other fertilization schemes by at least except treated with mineral fertilizatiion and the same tendency was observed for plant's height
Replication data for: Influence of fertilization scheme and sanitation measures on Irish Potatoe perfomance in Cameroon highland zone
No full textA field experiment was conducted in the Western Highlands of Cameroon to study the effects of Calliandra calothyrsus, sterilized compost, non-sterilized compost and mineral fertilizers (NPK 11:11:22) on physical characteristics, yield components and late blight disease severity of potato (Solanum tuberosum). A two factorial treatment combination made up of fertilization schemes and sanitary measures were laid out in a randomized complete block design (RCBD) with four replicates and 10 treatments. Data collected were subjected to a multivariate ANOVA and means separated with the Dunnett t-test with Calliandra calothyrsus considered as the main treatment. Mineral fertilizers and Calliandra calothyrsus significantly augmented stem diameter, plant height and plant vigor, total and marketable yields, despite the fact that late blight severity was high in the two treatments. The correlation matrix showed that total yield had significant and positive correlation with stem diameter (r = 0.74), plant height (r = 0.61), plant vigor (r = 0.61) and marketable yield (r = 0.99) and negative correlation (r = -37) with late blight severity. The increase observed is attributed to the nutrient contents of the treatments applied. Leafy prunings of C. calothyrsus increase soil organic matter which probably improves moisture retention and biological activity. The highest late blight severity recorded between the 45 and 60 coincides with active development of plant canopy which influences disease severity and create a canopy microclimate conducive to disease development. This study suggests that Calliandra calothyrsus has the potential of improving potato production provided appropriate fungicide is used
