The adsorption of chromium (VI) ions from aqueous solution was studied using pure and carbonized fluted pumpkin waste biomass (FPWB). The kinetic data shows a pseudo-first-order mechanism with rate constants of 1.26 × 10-2 and 1.933 × 10-2 mg g-1 min-1 for the pure and carbonized FPWB, respectively. While the pseudo-second-order mechanism has rate constants of 0.93 × 10-1 and 1.33 × 10-1 mg g-1 min-1 for the pure and carbonized waste biomass respectively. The pseudo-second order kinetic model was found to be more suitable for describing the experimental data based on the correlation coefficient values (R2) of 0.9975 and 0.9994 obtained for pure waste biomass (PWB) and carbonized waste biomass (CWB), respectively. The results obtained from this study show that PWB and CWB have very high removal capacity for chromium (VI) from aqueous solution over a range of reaction conditions. Thus, fluted pumpkin waste biomass (Telfairia occidentalis Hook F) is a potential sorbent for the treatment of industrial effluents containing chromium (VI) contaminant.DOI: http://dx.doi.org/10.3126/jncs.v27i1.6436 J.

Osmotic Agents

Purpose Leafy vegetables are known to be highly perishable because of high moisture content, which had resulted in applications of different preservative methods. However, these methods were not without certain limitations during storage. Osmotic pre-dehydration had been proved to be a better alternative because of high retention and improvement in nutritional qualities and stability during storage. This study aims to investigate the osmotic pre-dehydration of fluted pumpkin (Telfairia occidentalis) leaves. Design/methodology/approach Fluted pumpkin (T. occidentalis) leaves were pre-dried using sucrose, corn syrup and sodium chloride solutions as osmotic agents, while unosmo-predried leaves were used as the control. Both osmo-predehydrated and unosmo-predried leaves were dried in a hot air oven, whereas the effect of the osmotic agents on the nutritional qualities was investigated using standard protocols. Findings There were significant differences (p-values ranged from 0.001 to 0.030) in the proximate compositions of samples. Osmo-predried leaves recorded higher mineral contents in Ca, Cu, Fe, K, Mg, Mn and Na. Osmotic pre-dehydration by NaCl had a significant effect (p = 0.02) on ascorbic acid. The amino acid profile of the oven-dried leaves (unosmo-predried) showed that histidine and cysteine recorded high amino acid scores of 120.42% and 135%, respectively. Threonine (43.73%) recorded the highest essential amino acid score (without histidine). The economic evaluation indicated the percentage cost index difference of leaves treated with NaCl as 2.08%, sucrose (11.19%) and corn syrup (16.43%). Originality/value The high proportion of beneficial elements such as calcium, magnesium, phosphorus, potassium and appreciable chemical compositions of the osmo-predried leaves compared to unpre-dried leaves proved osmotic pre-dehydration as a value-added technique for preservation of leafy vegetables. The best osmotic agent was sodium chloride. This process could be applied on a small scale for the development of self-entrepreneurs and home-scale industries.

Leaf Yield

An experiment to ascertain the influence of fruit size on the yield of fluted pumpkin (Telfairia occidentalis Hook F.) was conducted in 2011 and 2012 at Nsukka. The mature fruits of T. occidentalis were graded into three length groups: large (more than 50 cm), medium (34-50 cm) and small (less than 34 cm). The experiment was laid out in randomized complete block design with six replications. The following data were collected: length of the longest vine, number of leaves/plant, vine diameter, marketable leaf and fruit yield. Data collected were subjected to analysis of variance while Genotype by Genotype x Environment interaction biplot was used to show which-won-where among the groups. Significant means were separated using Fisher’s least significant differences. Medium sized fruits gave the highest marketable leaf yield that was significantly higher than the small sized fruits in both years. Small sized fruits were significantly (p<0.05) lower in total leaf yield, fruit weight/hectare, fruit circumference (33.9 cm) and length (22 cm). The biplot explained 100% of the variation in the fruit sizes. Large sized fruits were the best performer in fruit length, while medium sized fruits performed better in total marketable leaf yield, average fruit weight, number of fruits/hectare and total fruit weight/hectare. The highest Benefit Cost Ratio of 1.2 and 2.6 in 2011 and 2012, respectively were obtained from medium sized fruits Medium sized fruit are recommended in favour of small sized fruit for leaf and fruit production, having higher economic returns.
