“…The physiological loss of weight was observed in both samples regardless of cultivation method and storage conditions. Similar results were obtained by Eboibi et al [20], where the loss of fruit mass was evident regardless of production method and calcium chloride treatment. The loss of weight affects the quality of fruits and vegetables, which is mainly due to excessive loss of moisture through metabolic activity such as respiration and transpiration processes [21].…”

“…Figure 6: Phosphorus concentrationThese findings affirmed earlier reports ofUguru and Obah (2020) andEboibi et al (2021), which stated that field practices significantly affects the phytochemical properties of agricultural materials. As revealed by the study's findings, cultivating groundnut with larger proportion of NPK 15:15:15 fertilizer, will be detrimental to the quality of biodiesel produced from the kernels.…”

The impact of pre-harvest treatments (field practices) on the fuel (biodiesel) properties produced from groundnut kernels was evaluated in this work. Ahigh-quality oil-yielding groundnut hybrid (SAMNUT 11) was grown under five different soil treatment regimes. The regimes were organic and conventional, though the treatment concentrations were systematically varied. Biodiesels produced from matured kernels (for the different treatment plans) were tested following the American Society for Testing Materials (ASTM) International and European Biodiesel (EN) procedures. Results obtained revealed that the biodiesel density ranged between 856 kg/m3 and 869 kg/m3, the acid value ranged between 0.695% and 1.118%, the iodine value ranged from 27.54 mg/L to 34.63 mg/L, the phosphorus concentration varied from 8.21 mg/L to 10.25 mg/L, the ester content ranged between 91.87% and 98.34%, and the alkali metals varied from 2.143 mg/L to 3.428 mg/L. All biodiesel produced fromthe pre-harvest treated kernels met the EN-ISO 12185 and EN 14213 standards for densities and ester contents, respectively. It was observed that the T2 and T3 acid values were 0.871% and 0.695%, respectively, while the T4 and T5 acid values were 1.033% and 1.118%, respectively, and all failed to meet both ASTM and EN standards, though the organically produced kernel’s biodiesels had better prospects. Furthermore, it was observed that the iodine values of the biodiesels, obtained from the five treatment plans, were within the EN 14214 approved standards for biodiesel. The findings portrayed that the organic manure had a more positive impact on the groundnut kernels, compared to groundnut grown with fertilizers. As observed from the results, the biodiesel produced from the organic kernels hada better fuel quality than that acquired from the convectional kernels.

“…Consequently, compost application is considered a successful agricultural strategy that improves the soil structure [ 27 ] and water holding capacity [ 28 ] as well as augments the soil nutrient availability [ 29 ], soil enzyme activity [ 30 ], and soil physicochemical characteristics under harsh environmental conditions [ 31 ]. The application of compost as a soil amendment is considered a cost-effective and eco-friendly method [ 31 , 32 ].…”

Plant growth and crop productivity under unfavorable environmental challenges require a unique strategy to scavenge the severely negative impacts of these challenges such as soil salinity and water stress. Compost and plant growth-promoting rhizobacteria (PGPR) have many beneficial impacts, particularly in plants exposed to different types of stress. Therefore, a field experiment during two successive seasons was conducted to investigate the impact of compost and PGPR either separately or in a combination on exchangeable sodium percentage (ESP), soil enzymes (urease and dehydrogenase), wheat physiology, antioxidant defense system, growth, and productivity under deficient irrigation and soil salinity conditions. Our findings showed that exposure of wheat plants to deficit irrigation in salt-affected soil inhibited wheat growth and development, and eventually reduced crop productivity. However, these injurious impacts were diminished after soil amendment using the combined application of compost and PGPR. This combined application enhanced soil urease and dehydrogenase, ion selectivity, chlorophylls, carotenoids, stomatal conductance, and the relative water content (RWC) whilst reducing ESP, proline content, which eventually increased the yield-related traits of wheat plants under deficient irrigation conditions. Moreover, the coupled application of compost and PGPR reduced the uptake of Na and resulted in an increment in superoxide dismutase (SOD), catalase (CAT), and peroxidase (POX) activities that lessened oxidative damage and improved the nutrient uptake (N, P, and K) of deficiently irrigated wheat plants under soil salinity. It was concluded that to protect wheat plants from environmental stressors, such as water stress and soil salinity, co-application of compost with PGPR was found to be effective.
