“…However, when unsaturated, 1% manure BC also increased Na. Taffouo et al [ 43 ] reported that root, stem, and leaf dry weight yields decreased in several V. unguiculata cultivars with increasing NaCl concentration. This negative effect was also observed in our study, where Na soil content was negatively correlated with V. unguiculata herbage (r = −0.64; Table 10 ) and root dry weight (r = −0.48; Table 10 ) yields.…”

We compared the effects of wood-, manure-, and blend-derived biochar (BC) saturated/unsaturated with dairy effluents on Vigna unguiculata and Cynodon dactylon performance and soil characteristics in a greenhouse pot study. Plant samples were assayed for herbage and root dry weight and N and C percentages. Soil samples were assayed for nutrients, pH, and conductivity. Variance analysis, Tukey’s tests, Pearson’s correlations, and multiple regression analysis were performed. The performance of C. dactylon was not affected. V. unguiculata’s herbage and root production responded negatively to manure BC and 2% of any BC, respectively, which is mainly explained by the conductivity and soil P increase, respectively. When V. unguiculata was grown, BC inclusion decreased NO3-N and increased the soil P content. When C. dactylon was grown, only P was altered (increased) when manure or the blend BC were applied. The soil total C increased as the BC loading rate increased. The application of high BC rates was detrimental for V. unguiculata, but showed a neutral effect for C. dactylon. To improve dairy waste recycling, saturated 1% blend BC and saturated 2% blend or manure BC could be applied to V. unguiculata and C. dactylon, respectively, with no short-term negative impacts. Only wood BC avoided soil P build-up. BC application increased the soil total C, showing potential for C sequestration.

The viability of using cellulosic Cymbopogon flexuosus root (CFR) fiber waste from the industry as a reinforcing material in a polyester-reinforced composite was investigated. Initially, CFR anatomy, mechanical, thermal, physio-chemical, morphological, and spectroscopy behaviors were investigated. Spectroscopy and chemical analysis were evidence for the richness of cellulose content (74.33%) in the fiber which reflected in increased tensile strength of 315.22 ± 61.72 MPa and thermal stability 272.31 C. Fiber reinforcement was varied from 0 to 50 wt% at random orientation and mechanical, and water absorption properties were correlated with the glass fiber reinforced composite of the same weight percentage. The composite with a 40% fiber combination has an enhancement in mechanical, morphological, and thermal characterization. This comprehensive study confirms the usage of this bio-material in replacing harmful synthetic material in structural, marine and mechanical industrial applications.

Soil salinity has a negative impact on crop production over the world. The effect of salt stress on growth, chlorophyll content, mineral distribution, biochemical constituents and non-enzymatic antioxidant compounds of white yam (Dioscorea rotundata (L) var. gana) cultivar regularly consumed in Cameroon were investigated. Plants were subjected to four different levels concentrations of NaCl (0, 50, 100 and 200 mM), with 0 mM NaCl as a control. The supply of intake doses of NaCl in the culture medium significantly (P < 0.001) decreased the dry biomass (roots and shoots), growth parameters (number of leaves, noose diameter, leaf area and stem height) and chlorophyll contents from 100 mM NaCl. Mineral elements (K, Ca and Mg) and K/Na ratio significantly (P < 0.001) decreased in roots and shoots with increasing salinity. The higher sodium (Na) concentrations were recorded in shoots than in roots. The different biochemical constituents (proline (PRO), total soluble carbohydrates (CH), soluble proteins (PR) and total free amino acids (FAA)) and non-enzymatic antioxidants compounds (total phenolic (TP) and flavonoids (FLA) contents) significantly (P < 0.001) increased from 50 mM NaCl. The main strategy in cv. gana seems to increase osmotic adjustment through high accumulation of CH, PR, FAA and PRO in the leaves and they could eventually be considered as biochemical indicators of early selection and osmotic adjustment ability for salt tolerant plants. The gana variety could be encouraged to be planted on salt affected soils for the better development in salty areas.
