“…Therefore, the present study more readily favors the better TDS management because of the significant nutrient or salt uptake by plants. Similar conclusions are also made by other researchers that phytoremediation could be a better approach for the management and disposal of saline wastewater with higher TDS ( Ghotbizadeh and Sepaskhah, 2015 ; Roongtanakiat and Akharawutchayanon, 2017 ; Golabi et al, 2018 ; Yousaf et al, 2021 ). Comparison of means between initial and final values of root and shoot weight, plant height, nutrient uptake, and chlorophyll content are shown in Tables 8 , 9 .…”

The present study focuses on determining the phyto-treatment efficiency for treatment of moderately saline wastewater using organic raw materials, such as rice husk, coconut husk, rice straw, and charcoal. The moderately saline wastewater with total dissolved solids (TDS) concentration up to 6143.33 ± 5.77 mg/L was applied to the lysimeters at the rate of 200 m3 ha–1 day–1 in five different lysimeter treatments planted with Eucalyptus camaldulensis (T1, T2, T3, T4, and T5). T1 was a control without any filter bedding material, whereas rice straw, rice husk, coconut husk, and charcoal were used as filter bedding materials in the T2, T3, T4, and T5 treatment systems, respectively. Each treatment showed significant treatment efficiency wherein T3 had the highest removal efficiency of 76.21% followed by T4 (67.57%), T5 (65.18%), T2 (46.46%), and T1 (45.5%). T3 and T4 also showed higher salt accumulation, such as sodium (Na) and potassium (K). Further, the pollution load in terms of TDS and chemical and biological oxygen demand significantly reduced from leachate in the T3 and T4 treatments in comparison with other treatments. Parameters of the soil, such as electrical conductivity, exchangeable sodium percentage, and cation exchange capacity did not show values corresponding to high salinity or sodic soils, and therefore, no adverse impact on soil was observed in the present study. Also, Eucalyptus camaldulensis plant species showed good response to wastewater treatment in terms of growth parameters, such as root/shoot weight and nitrogen, phosphorus, and potassium (NPK) uptake, plant height, biomass, and chlorophyll content. Root and shoot dry weight were in the order T3 (51.2 and 44.6 g)>T4 (49.3 and 43.5 g) > T5 (47.6 and 40.5 g) > T2 (46.9 and 38.2 g) > T1 (45.6 and 37.1 g). Likewise, the total chlorophyll content was highest in T3 (12.6 μg/g) followed by T4 (12.3 μg/g), T5 (11.9 μg/g), T2 (11.5 μg/g), and the control, that is, T1 (11.0 μg/g). However, the most promising results were obtained for T3 and T4 treatments in comparison with the control (T1), which implies that, among all organic raw materials, coconut and rice husks showed the highest potential for salt accumulation and thereby wastewater treatment. Conclusively, the findings of the study suggest that organic raw material–based amendments are useful in managing the high salts levels in both plants and leachates.

“…Various chemical contaminants like suspended solids, dissolved oxygen, nitrogen, phosphorus and heavy metal etc. have minimized in India, China, Australia and Venezuela using phytoremediation plants (Roongtanakiat and Chairoj, 2001;Troung et al, 2008). Jean-Paul et al ( 2002) also compared the success of phytoremediation in USA and Europe and several successes in many experimented sites were reported.…”

Industrialization in the Niger Delta region of southern Nigeria has resulted in excessive discharge of industrial wastes, especially oil spillage. Farming in this region has declined and cotton farming has not survived there due to this menace. Phytoremediation, which is an emerging green technology has been adopted for the revitalization of farming in polluted sites and has been integrated towards solving this challenge. Many indigenous plants of high phytoremediation strength within and outside Nigeria have been reported. The use of genetic engineering approaches for developing transgenic plants with higher phytoremediation potential have also been successful in certain plants. This review, therefore, focused on phytoremediation, its impact, success, potential plants, plant's phytoremediation mechanisms, and the technological advancement need through cotton genetic engineering. Cotton is the foremost commercially important fiber crop and its fiber is the backbone of the textile industry. It has significant impact in the economy but its phytoremediation strength is naturally poor; hence, prompting attention to the genetic modification of cotton for phytoremediation purposes and basing the future phytoremediation on the use of transgenic economic plants, especially cotton, are of significant importance.

Vetiver introduced as perennial grass crop in Mediterranean basin is tested for its potential fodder ability. Effects of nitrogen (N) fertilization, on growth, yield and forage quality parameters were assessed during two cropping seasons using a randomized complete block design with three replicates. Three N levels as ammonium-nitrate, were tested: 0, 30 and 60 kg N ha-1. Results showed that biomass increases under maximum N rate compared to control. The improvements in fresh and dry weights were 39.61% and 257.14%, respectively. Second cutting increased DY by 14.70% compared to first cut. Forage yield increase was closely related to a rise of number of tillers by 24.7% under 60 kg N ha-1. The increased tillers enhanced forage yield by 14% during cropping seasons. N produced a linear increase in crude protein under 30 and 60 kg N ha-1 of 40% and 63.8%, respectively. In addition, the increase of leaf cellulose content was less impacted by N fertilization allowing vetiver to be more digestible forage. The results showed that vetiver could be grown as a forage crop in Mediterranean areas. N fertilization since a low rate of 30 kg N ha-1 is su􀵶 cient to stimulate regrowth, increase biomass yield and nutritional value.
