    Reuse of Treated Wastewater to Produce Legume Grains (case study alfalfa and vetch)
    (2014) Ahmed Jabri Mohamed Lebdi; Dr. Numan Mizyed; Dr. Hassan Abu Qaoud
    This study was conducted to evaluate the production of two fodder crops; common vetch (Vicia sativa L.), and Alfalfa (Medicago sativa L.) irrigated with treated wastewater. The study was implemented during summer 2012. Five water regimes were used in the experiment including: Irrigation with fresh water (control), fresh water supplied by 10 ppm N–P–K fertilizers, treated wastewater, treated wastewater supplied with 10 ppm N–P–K fertilizers, and treated wastewater supplied with 40 ppm N–P–K fertilizers. The crops were planted in 5 liters plastic pots in 4:1 v/v sandy to clay soil. The soil was analyzed before and after planting. The following plant parameters were recorded: Plant high, fresh weight, dry weight, leaves number per plant, fruit number per plant and fruit weight per plant. The results show that using treated wastewater significantly increased production parameters; the highest production was obtained with treated wastewater supplied with 40 ppm fertilizers (plant height was 81.5 cm for vetch and 112.5 cm for alfalfa). Plant fresh weights for both vetch and alfalfa were higher in treated wastewater treatments than those of fresh water treatments. Regarding the dry weight, irrigation with TWW produced (33.83 g/plant and 44.67 g/plant ) compared to 22 g/plant and 24.5 g/plant for irrigation with fresh water for vetch and alfalfa respectively. The results of soil analysis show an increase in soil content of nitrogen, phosphorus and potassium, as well as an increase in the soil salinity and SAR values in pots irrigated by treated wastewater alone and in treated wastewater plus 10 and 40 ppm N-P-K fertilizer.

    Salinity Management for Barley Productionin Brackish and Treated Effluent Irrigated Agricultural Systems
    (2013) Maher Abd Allah Ahmed Salahat; Prof. Dr. Marwan Haddad; Dr. Numan Mizyed
    Marginal water resources such as brackish, and treated waste water are promising water resources as alternatives for fresh water to be used in agriculture specially crops with high tolerance to salinity such as barley. This study aims to; evaluate the effect of five different water concentrations on the behavior and productivity of five different barley varieties to demonstrate the salinity tolerance of each variety. Five barley varieties Hordium Vlgure were cultivated under five different water applications, the applications included fresh water(Fw) as a control with TDS concentration of 442 ppm , treated wastewater (Tww) with salinity of 1200 ppm, and three levels of water salinity. The levels of salinity were: S1 (1080 ppm), S2 (3240 ppm), and S3 (9720 ppm). The experiment was designed under CRBD by split plot design with 3 replications. The results of the experiment showed that in all cases there is a significant (p≤0.05) difference between the high concentration (S3) and other concentrations, causing a reduction in the grain and straw yields of barely. Also, the analysis show that straw yield and height of plants were significantly smaller for the high salinity concentration (S3). Results also showed that there is a significant increase in yield when using Tww compared with other treatments. When treated wastewater was used, the grain yield, straw yield and height of plants were significantly higher than those in the other treatments for all varieties of barley. On the other hand, concentrations S1, S2 and Fw didn't show significant differences among them in terms of grain yield. However, S1 and S2 didn`t give significant differences in straw yield, and there was no significant difference between S2 and Fw. For height, S3 treatment produced significantly shorter plants. Tww treatment produced plants higher than those of other treatments. According to varieties, variety 4 and variety 1 gave the highest yield of grains and there are significant differences among variety 4 and varieties 2,3,and5 while there was no significant difference among varieties1, 2, 3, and 5. On the other hand it was observed that there was no significant differences between varieties 4 and 1 For straw yield, varieties 1 and 4 showed the highest yield so, there were significant differences between variety1 and varieties 2,3, and 5. There was a significant difference between variety 4 and varieties 2, 3, and 5. It has been concluded no significant differences between 4 and1. For interaction between salinity and variety, the environmental conditions should be the main reason for selecting the suitable variety. Its clear that the use of brackish water and Tww in irrigating such crops will be promising and saving traditional water sources for domestic uses. which couldn't use Tww and brackish water for that.
