“…(kal) showed that, except for C. aconitifolius, the 13 TLVs displayed a higher average Ca content. 61 The Mg (1170.0/1060.0 mg/ kg), Fe (21.3/14.8 mg/kg), Mn (20.5/13.4 mg/kg), and Zn (20.5/13.4 mg/kg) content is considerably lower than the chosen TLVs except for Fe in C. asiatica and I. aquatica, Mn in B. alba, and Zn in I. aquatica. These comparative results show the potential of the 14 TLVs to provide an equal or greater number of minerals.…”

Traditional leafy vegetables (TLVs) are rich in beneficial bioactive compounds and mineral elements. The rural areas of Kerala, India, have a diversity of unconventional TLVs, and only limited research is available on their nutritional and biochemical composition. Therefore, this study was designed to evaluate the mineral elements, metabolites, antioxidants, antioxidant activity, and proximate composition of 14 TLVs. The results show that among the selected TLVs, Talinum triangulare exhibited the highest Zn (1214 mg/kg DW) content, whereas the highest amount of Ca (13,532 mg/kg DW) was found in Centella asiatica. GC−MS analysis of these 14 plants unveiled a total of 193 metabolites. The metabolic pathways with high impact were associated with alanine, aspartate, glutamate, galactose, and glyoxylate−dicarboxylate metabolism and aminoacyl tRNA synthesis. Several metabolites showed differential expression across the samples. Celosia argentia, Ipomoea batatas (sweetheart cultivar), and Ipomoea aquatica showed the highest expression of metabolites such as caffeic acid and xylitol. I. batatas cv. sidekick black (0.49 mg/mL) and Cnidoscolus aconitifolius (0.135 mg/mL) demonstrated the highest antioxidant activities. The 14 plants had varying levels of fiber (2.01−7.31%), fat (2.68−9.36%), protein (4.55−22.32%), and carbohydrate (34.62−69.3%). Overall, these TLVs have high nutritional potential and health-protecting properties, which can boost the well-being of consumers.

“…Weight increased significantly with manure application to the optimum bud combination of cabbage. Farmyard manure fertilizer rates with different bud numbers responded differently to the head weight of cabbage [ 46 ]. Head weight is one of the most important characteristics for measuring yield performance.…”

Cabbage (Brassica oleracea var. capitata L.) is a popular leafy vegetable in Ethiopia. However, the production and productivity of the crop are often constrained by several factors, such as deprived soil fertility and poor agronomic practices. Thus, a study was conducted in two locations in the East Gojjam zone of northwestern Ethiopia during the 2021/2022 cropping season to evaluate the effect of bud numbers and farmyard manure fertilizer rates on the growth and yield components of cabbage. Three numbers of cabbage buds (1, 2, and 3) and four levels of farmyard manure (0, 2.5, 5, and 7.5 tons/ha) were laid out in a 3 × 4 factorial arrangement in a randomized complete block design with three replications. Data on yield and quality were recorded and subjected to analysis of variance. The results revealed that growth, yield, and quality components were significantly influenced by the interaction effects of bud number and farmyard manure fertilizer rate. In both locations, the highest marketable (41.8 tons/ha) and total (43.1 tons/ha) yields were attained from the combined effects of 2 buds of cabbage and 5 tons of farmyard manure. The highest medium-sized heads (31.8 tons/ha) of cabbage were also recorded from the combination of 2 buds with 5 tons of farmyard manure. Moreover, the combined effects of 2 buds and 5 tons of farmyard manure showed the highest net benefit (5,679.03 US dollars) over the other treatments at the two locations. Hence, based on the results of the study, the combination of 2 buds and 5 tons of farmyard manure fertilizer can be suggested for the economical production of cabbage in northwestern Ethiopia and similar environments.

Zeolites Reduce the Transfer of Potentially Toxic Elements from Soil to Leafy Vegetables

The ability of natural zeolite amendment to reduce the uptake of potentially toxic elements (PTEs) by lettuce, spinach and parsley was evaluated using pot experiments. PTE concentrations in roots and shoots, as well as the pseudo total (PT), water soluble (WS) and bioavailable (BA) PTE fractions in the amended soils, were assessed. Although the PT PTE concentration was high, the WS fraction was very low (<0.4%), while the BA fraction varied widely (<5% for Cr, Mn and Co, <15% for Ni, Pb and Zn, >20% for Cd and Cu). PTE concentration decreased in both roots and shoots of all leafy vegetables grown on zeolite amended soils, especially at high amendment dose (10%). The uptake of PTEs mainly depended on plant species, PTE type and amendment dose. With the exception of Zn in spinach, the bioaccumulation factor for roots was higher than for shoots. Generally, lettuce displayed the highest PTE bioaccumulation capacity, followed by spinach and parsley. Except for Zn in spinach, the transfer factors were below 1 for all PTEs, all plant species and all amendment doses. Our results showed that the natural zeolites are promising candidates in the reclamation of contaminated soils due to their ability to immobilize PTEs.
