“…This supply deficit should serve as motivation for cassava farmers to produce more. According Nwokoro et al. (2002) and Kormawa and Akoroda (2003) , close to 84% of domestic cassava production is available for consumption while the remaining 16% is available for industrial use in Nigeria with a caveat that more proportion could go into the industrial sector in future.…”

This study analyzed the compound growth rate (CGR) and the contributions of yield and area to cassava production output in Nigeria. During the period, TE1970 – TE2018, production followed an upward trajectory from 9.3 million tonnes (1970) to 59.5 million tonnes (2018) while yield oscillated between 7.9tonnes/ha (TE2014) and 11.9tonnes/ha (TE2010). At this period, the CGR per year for yield declined (-0.2%), harvested area increased (10.9%) and production increased (10.6%). The decomposition analysis for the period revealed that, increase in output was largely due to expansion of harvested area (152%) while the interaction between area and yield effect declined production output by 45.8%. Regrettably, during the period, cassava yield also declined production output by 5.8%. The study also found that harvested area has the highest instability index (11.8). In order to further increase and sustain cassava production in Nigeria, intense planting of high yield cassava stems instead of solely expanding cropped area is recommended.

“…The plant is propagated mostly from stem cuttings. More than two-thirds of the total production of cassava is used as food for humans, with lesser amount being used for animal feed [11] and industrial purposes. The primary goal of this trial is to identify genotypes of high beta-carotene content of adaptive capacity with resistance to major diseases and pests for possible release to Nigeria farmers and clones for the introgression of other desirable traits through genetic modification.…”

Thirteen cassava genotypes were evaluated from advanced field trial for total carotene content (TCC), % dry matter content (DMC), fresh root yield (FRY) and biotic stresses alongside two widely cultivated cassava varieties (UMUCASS 36 and TMS 30572) as checks in 2013/2014 cropping season at research station of National Root Crops Research Institute (NRCRI) Umudike in Nigeria. The objective of the experiment was to select promising clones for possible release to Nigeria farmers. The results of the TCC analysis ranged from 1.68-10.16 µg/g. Genotypes NR11/0063, NR11/0123 and NR11/0140 had TCC ranged from 10.47-8.72 (µg/g) which are above the national checks (UMUCASS 36 and TMS 30572) of 8.34 and 1.68(µg/g) respectively. The DMC of the genotypes ranged from 33.0-15.0 %. TMS 30572 gave the highest DMC (33.0%) while genotype NR11/0064 had the least (15.0%) DMC. Severity of cassava mosaic disease (CMD), cassava bacterial blight (CBB), cassava green mite (CGM) and cassava anthracnose disease (CAD) evaluated for 12 months varied among the genotypes. Symptom expressions of CMD, CBB and CAD were relatively higher (3.0) for genotype NR11/0123 and this resulted to low fresh root yield (FRY) of 18 t/ha whereas TMS 30572 with moderate severity (1.8) had a higher FRY of 32.6 t/ha. The severity of CGM was moderate across the genotypes with no significant difference (P<0.05) observed. Further analysis showed that CMD, CBB and CAD were significantly correlated (r=0.618, 0.699 and 0.621, p<0.05) with harvest index (HI) among the genotypes evaluated. Three genotypes were selected for further evaluation and possible release to Nigeria farmers.

“…In South America, Africa and Asia, its cultivation is considered as the most important for the production of food [9] and economic, because they provide 40%, as carbohydrates as rice, needed to generate the calories required for the daily human and animal diet. Of the total yucca production in Nigeria, one third is used for animal feed and industrial purposes [10].…”

The purpose of this investigation was to evaluate the coagulant power of 5 natural combinations to clarify the water of a wetland. The clarification process was simulated with the jar test and a rapid agitation at 120 rpm was established for this test for 1 minute, slow agitation at 30 rpm for 20 minutes and sedimentation for 15 minutes. For the natural combinations, a ratio of 90-10, 80-20, 70-30, 60-40, and 50-50yucca -seeds of Moringa oleifera was determined. After the process, the turbidity of the water was compared with a control sample. It was determined that the best results were obtained with treatment 2, 4 and 5 that removed the turbidity of the water from the wetland in 89.7%,93.0 and 93.4% and 93.4% respectively.
