In this work, the pomological characteristics, phenolic composition, and chemical contents modification in response to treated wastewater (TWW) irrigation was studied on olive fruits. The experiment was carried out during two successive years (2016/2017) on olive trees (cv. Chemlali). Three irrigation treatments were adopted and two TWW irrigation levels were applied (T1: 20% ETc; T2: 40% ETc; CT: Control Treatment (rainfed condition)). Results show that TWW irrigation leads to increased fruit fresh weight and water content, whatever the level applied. In addition, fruit oil content remained unaffected by TWW irrigation. Moreover, this agronomic practice preserves some phenolic compound contents like verbascoside, therefore fruits nutritional value. A positive feature was then observed following TWW irrigation. In fact, oleuropein, tyrosol, luteolin-7-glucoside, and pinoresinol amounts were enhanced in treated olive fruits. On the other hand, TWW irrigated trees with a level of 40% ETc (T2) produced olive fruits richer in Mg and K than those cultivated in rainfed conditions (CT). Fruits Zn, Mn, and Pb contents decreased as a result of olive trees TWW irrigation.

Twenty-year-old “Chemlali” olive trees trained to vase and rainfed were investigated in either “on” (2004) or “off” (2003) year. A randomized block design with three blocks and three treatments was used and each experimental plot consisted of nine olive trees. Three treatments were applied: (1) rainfed conditions (RF, used as control treatment); (2) irrigation with well water (WW); and (3) irrigation with treated wastewater (TWW). Irrigation with TWW led to a significant increase of root N, P, Ca, Zn, Mn, Na, and Cl concentrations, in particular in the on-year. Data showed significant differences, between the two years, for the concentration of the mineral elements in the roots, with general lower values in the on-year, probably as a consequence of nutrients movement upward in the tree. Fruit N, P, K, Zn, Mn, and Cl contents were significantly higher in TWW irrigated trees with respect to both RF and WW trees, whereas similar values for Ca, Mg, Na, and Cl contents were measured for WW and TWW irrigated trees. The irrigation with TWW allowed to reuse problematic waters and to save nutrients inputs in the olive orchard thus moving towards a more sustainable management of olive orchards in countries where water is the major limiting factor for agriculture.

This study aimed to evaluate the effect of sustainable treatment of wastewater on the irrigation of radish cultivated in greenhouses. The study was conducted at the Federal University of Campina Grande, Campina Grande, PB, Brazil. The experimental design was randomized blocks a 3x3 factorial scheme, with the factors being three qualities of water (water treated by wetland, water treated by wetland + UASB and control treatment (water from the local supply system)) and three micro-irrigation systems (subsurface drip, surface drip and micro sprinkler), with four replications. Waters treated by sustainable systems such as wetland and wetland + UASB, were not considered suitable for irrigation of leafy crops according to the guidelines of CONAMA resolution 357/2005. The sustainable treatment wetland + UASB and drip irrigation showed the best results in growth and production of radish. The radish root diameters were within the range considered ideal by the consumer market. Further studies with combinations of sustainable water treatment systems are needed aiming to frame the treated wastewater quality to the requirements of CONAMA resolution 357 for irrigation of leafy crops.   Keywords: reactor UASB, wetland, Raphanus sativus, reuse, microirrigation.         SILVA, P.

Membrane Bio Reactor(MBR) methods is considered as one of the most advanced used technology in waste water treatment. The aim of this technology is to obtain high quality treated waste water. This study conducted to investigate the ability of using of sewage water from zaafrania city for irrigation and their effect on corn growth and some of soil chemical properties which include electrical conductivity and soil pH in extract soil paste and the micro nutrient content in soil and plant which include Fe, Mn, Zn, Cu, Cd, Pb. Three levels of wastewater were used 0, 50, 100% in two stages, the three levels of wastewater ( without soil fertilization ) were used in the first stage, where 21.8 Kg P/D +80 N Kg/D was added to the soil as fertilizer in the control 0% treatment and 10.9Kg P/D +40 Kg N/D were added to 50 and 100% levels in the second stage. Corn seeds were planted in 10kg plastic pots in Completely Randomized Block Design in three replicates. The results refer to a high significant increase in plant height, fresh and dry weight for all treatments in comparison with control treatment. The low add level of wastewater 50%+ half of fertilizer recommendation gives a significant increase of plant height and fresh and dray weight. The results showed a high increased of electrical conductivity for 50, 100% wastewater added levels for both stages compared with control treatment. The high add level 100% gives high significant increase of electrical conductivity compared with the low level of the wastewater. Whereas the values of soil PH were close to the neutral for all treatment. The result showed a significant increase in micro nutrients content (which include Fe, Mn, Zn, Cu, Cd, Pb) in soil and plant for all treatment compared with control treatment, this increased was continues with the increase of additional level of wastewater. However all the micro nutrient was within the allowed natural limits and not reached the toxic limits in soil and plant.

Background: Sugarcane silage (SCS) has often been characterized by large dry matter (DM) losses associated with reduction in soluble nutrients and increase in indigestible fiber. Objective: To evaluate the effect of including discarded fruits on the losses and nutritional value in SCS. Methods: A completely randomized design was used with five treatments andfive replications. Silageswere added with 15% (as-fed basis) papaya (Carica papaya) (SP), acerola (Malpighia glabra) (SA), banana (Musa sp.)(SB) or tomato (Solanum lycopersicum) (ST). The control treatment was composed only of SCS. Twenty-five (25-L) plastic buckets were used to make the experimental silos, which were opened on the 90th day after their closure. Data were analyzed by analysis of variance. Results: Gas losses and total DM losses were lower and DM recovery was higher in SB and SA than in the control (p>0.05). However, there was treatment effect for lactic and acetic acids, ammonia nitrogen contents, lactic acid bacteria, and yeasts and mold counts (p<0.05). Conclusion: The inclusion of 15% banana or acerola in SCS decreases losses and increases DM recovery. Furthermore, the inclusion of 15% banana improves the nutritional value of SCS.Keywords: additives, animal feeding, crop byproduct, fiber content, forage conservation, discard fruit. ResumenAntecedentes: El ensilaje de caña de azúcar (SCS) es frecuentemente caracterizado por grandes pérdidas de materia seca (DM) asociadas con reducciones en los nutrientes solubles y aumentos en la fibra indigestible.

The objective of this study was to evaluate the productive performance of sunflower plants irrigated with different levels of domestic treated sewage and groundwater well with different doses of nitrogen. It was used randomized blocks design in split-split plots with four replications. In the plots, we evaluated the effect of two types of irrigation water, in the subplots we evaluated the five irrigation levels expressed as 25, 50, 75, 100 and 125% of the Class A pan Evaporation (CAE), and in the sub subplots, we evaluated the effect of four different doses of nitrogen (25, 50, 75 and 100 kg ha-1). The irrigation of sunflower with domestic sewage produced greater yield potential of grain and oil. The use of water from treated wastewater can replace up to 50 kg N ha-1 without affecting productivity. It is recommended for the commercial production of sunflower the use of treated sewage water with irrigation depth relative to 100% of CAE (296.64 mm) and nitrogen of 25 kg ha-1.

The aim of this report was to study the effect of salinity (control: 2dS/m, S1: 4 dS/m and S2: 6 dS/m) and harvest time (first harvest on 9 May 2018 and second harvest on 19 April 2018) on the growth and the chemical composition of Centaurea raphanina subsp. mixta plants. The plants of the first harvest were used for the plant growth measurements (fresh weight and moisture content of leaves, rosette diameter, number and thickness of leaves), whereas those of the second harvest were not used for these measurements due to the flowering initiation, which made the leaves unmarketable due to their hard texture. The results of our study showed that C. raphanina subsp. mixta plants can be cultivated under mild salinity (S1 treatment) conditions without severe effects on plant growth and yield, since a more severe loss (27.5%) was observed for the S2 treatment. In addition, harvest time proved to be a cost-effective cultivation practice that allows to regulate the quality of the final product, either in edible form (first harvest) or for nutraceutical and pharmaceutical purposes as well as antimicrobial agents in food products. Therefore, the combination of these two agronomic factors showed interesting results in terms of the quality of the final product. In particular, high salinity (S2 treatment) improved the nutritional value by increasing the fat, proteins and carbohydrates contents in the first harvest, as well as the tocopherols and sugars contents (S1 and S2 treatments, respectively) in the second harvest. In addition, salinity and harvest time affected the oxalic acid content which was the lowest for the S2 treatment at the second harvest. Similarly, the richest fatty acid (α-linolenic acid) increased with increasing salinity at the first harvest. Salinity and harvest time also affected the antimicrobial properties, especially against Staphylococcus aureus, Bacillus cereus and Trichoderma viride, where the extracts from the S1 and S2 treatments showed high effectiveness. In contrast, the highest amounts of flavanones (pinocembrin derivatives) were detected in the control treatment (second harvest), which was also reflected to the highest antioxidant activity (TBARS) for the same treatment. In conclusion, C. raphanina subsp. mixta plants seem to be tolerant to medium salinity stress (S1 treatment) since plant growth was not severely impaired, while salinity and harvesting time affected the nutritional value (fat, proteins, and carbohydrates) and the chemical composition (tocopherols, sugars, oxalic acid, fatty acids), as well as the bioactive properties (cytotoxicity and antimicrobial properties) of the final product.

Potato cultivation is quite demanding in inorganic nutrients and adequate fertilization is a key factor for maximizing yield and producing tubers of high quality. In the present study, a field experiment was carried out to evaluate the effect of various forms of fertilization on crop performance and the nutritional value and chemical composition of two potato varieties (cv. Spunta and cv. Kennebec). For this purpose, five different fertilizer treatments were applied namely: control (C), standard fertilizer (T1), standard fertilizer + zeolite (T2), manure (T3) and slow release nitrogen fertilizer (T4). According to the results, it was observed that slow release treatment (T4) achieved the highest yield for both varieties, while the control treatment presented significantly lower yield compared to the studied fertilization regimes. The dry matter of leaves and shoots was higher in T1 treatment for cv. Kennebec and in T2 and T4 treatments for cv. Spunta, whereas the control treatment presented the highest dry matter content in tubers for cv. Kennebec and T2 and T3 treatments for cv. Spunta. A significant effect of the fertilization regime was also observed on the nutritional value of tubers and more specifically the protein, ash and fat content was increased by treatments T1 and T4, while carbohydrate content was also increased by T3 and T4 treatments for both varieties. Similarly, the total sugars, organic acids, β-carotene and lycopene content was increased in T3 treatment for the Spunta variety, while the antioxidant capacity showed a varied response depending on the fertilizer regime and the tested variety. In conclusion, the fertilization regime has a significant effect not only on the tuber yield but also on the quality of the final product and should be considered as an effective tool to increase the added value of potato crop.
