Recycling of domestic wastewater treated by vertical-flow wetlands for irrigating Chillies and Sweet Peppers

Microbial contamination of Capsicum annuum irrigated with recycled domestic wastewater treated by vertical-flow wetlands

“…Sodium azide and kanamycin provide the selective inhibition required, whilst iron salts and aesculin form an indicator system for the presumptive identification of Enterococci (Mossel et al, 1978). This agar was prepared by dispersing 43 g of powder in one Table 3 Experimental design (after Almuktar et al, 2015) in terms of plant number allocations after the third planting).…”

“…Harvested chilli fruits from each plant were categorised according to the chilli classification scheme in Table 2, which has been adapted from Almuktar et al (2015). The variables length, width, weight and bending were used for classifying the harvested fruits.…”

“…Wastewater recycling makes particularly sense for popular, relatively expensive and easy-to-grow plants such as chillies, peppers, tomatoes, eggplants, lettuces and cabbages (Almuktar et al, 2015). Most of these plants are rich in vitamins and trace minerals.…”

Effect of Substrate, Feeding Mode and Number of Stages on the Performance of Hybrid Constructed Wetland Systems

“…Similarly to other forest and agricultural waste/by-products, the low efficiency of the palm mulch in the removal of the negatively charged phosphate ions can be attributed to the abundant availability of negatively charged functional groups (e.g., -OH, -COOH) and the absence of positively charged functional groups (e.g., -NH 2 ) on its surface [20]. Nevertheless, far from being a disadvantage the modest efficiency of CWs in the removal of N and P can be regarded as a way to decrease the demand for expensive inorganic fertilizers in agriculture [39]. For instance, García-Delgado et al [40] saved considerable amounts of fertilizer (37% N, 66% P and 12% K) by applying treated urban wastewater in pepper cultivation.…”

Response of Bell Pepper Crop Fertigated with Nitrogen and Potassium Doses in Protected Environment

“…For this reason it is required greater attention with the supplementation of these nutrients. Almuktar et al [8] noted the negative impacts on growth development of bell peppers, possibly due to the high concentrations of nutrients and minerals.…”
