Phosphate (PO43-) and Nitrate (NO3-) are two main nutrients that cause water eutrophication. In the other hand, the presence of PO43- and NO3- is needed for plant growth. The aims of this study are to recycle Spent Coffee Ground (SCG) modified with calcium hydroxide for adsorption PO43- and NO3-. The optimum adsorption capacity for PO43- and NO3- is 36.74 mg/L and 20.21 mg/L, respectively. The Freundlich isotherm model was suitable for PO43- and NO3- adsorption. The kinetic model for adsorption was linear using Pseudo-second order. The application of modified SCG after enrichment with PO43- and NO3- for plant growth (Raphanus sativus) showed optimum growth at a dose of 0.3% with value of germination index was 203%.

This study was aimed to determine the level of selected metals and nutritional composition of pigeon pea seed collected from seven districts of Wolaita zone. A wet digestion procedure involving the use of mixtures of (69% - 72%) HNO3 and (70%) HClO4 at an optimum temperature and time duration was used to determine metals by using flame atomic absorption spectrometry. Kjeldahl digestion method, Soxhlet extraction and furnace were used to determine nutritional values of pigeon pea, and physicochemical properties of soils were assessed using standard methods. The results showed that the levels of concentration of metals in mg/kg dry weight were ranged 105.17 to 144.07 for K, 8.95 to 12.67 for Mg, 7.74 to 12.27 for Ca, 0.247 to 0.543 for Fe, 0.122 to 0.313 for Zn, 0.061 to 0.432 for Mn, 0.087 to 0.134 for Cu and 0.0011 to 0.00196 for Cr. The proximate composition of pigeon pea was in the range of 19.28% to 25.79% for crude protein, 0.993% to 1.75% for crude fat, 3.75% to 5.31% for ash, 10.65% to 13.73% for moisture, 2.28% to 3.06% for fiber, 54.36% to 60.1% for carbohydrate and 326.8 to 345.23 Kcal for energy. The pH of the soil was in the range from pH 5.09 (strongly acidic) to 6.77 (slightly acidic), EC of the soil ranged from 0.047 to 0.14 dS/m (low), the soil OC level was from 1.6% to 2.42% (moderate), total Nitrogen was from 0.12% to 0.23% (low to moderate), the available Phosphorus content of the soil was from 6.82 to 13.52 mg/kg (low to moderate), CEC value of the soil was from 14.8 to 23.53 meq/100g (moderate). The textural classes of soil were sandy clay loam for all sites except Abela abaya. The study confirmed that pigeon pea was a good source of proteins, carbohydrates, and selected metals such as Mg, K, Ca, Fe, Zn, Mn, Cu, and Cr. The concentration of metals and nutritional compositions of pigeon pea seed were found at a permissible level.

Agrotechnical assessment of struvite produced by a lab-scale sedimentation unit is performed. As a source of phosphates and ammonia, liquor obtained through dewatering of Мunicipal wastewater treatment plant sludge was in use. The range of phosphates and ammonia was in the range of 130 - 250 and 380 - 560 mg/L, respectively. Seawater brine with a magnesium concentration of around 60 g Mg 2+ /L was applied as a source of magnesium. The agrotechnical characteristics of struvite obtained were compared to ammonium nitrate and carbamide in regards to the productivity effects on maize hybrid P9241. The results show that the effectiveness of struvite and some commercial fertilizers is quite close. The highest yield in the experiment was achieved with the application of carbamide plus ammonium nitrate (56.64 kg/ha), while in applying struvite solely it is 54.60 kg/ha. The highest protein content of maize (9.7%) was observed in the case of struvite/ammonium nitrate application.

In Benin, market gardening has become a new profession and plays an important role in the supply of fresh vegetables. In the coastal regions, fish farming is practiced on the outskirts of market gardening sites. However, poorly regulated cultivation practices and increasing pollution do not necessarily guarantee the sanitary quality of the products delivered. This study aims to evaluate the physico-chemical qualities of the water used for watering and, secondly, the lead and cadmium contamination of the water used for watering, the soil (sediment) and the fish products (fish) on the urban market gardening perimeter in the commune of Lokossa in Benin. These various samples taken for this purpose were analysed at the Ministry of Health’s Water and Food Quality Control Laboratory. We noted pollution of organic elements and FAO standards. The consequences of this contamination are health risks for consumers.

Competition for natural resources will affect our ability to produce food. As population grows so does food demand, which leads to enormous pressure on the supply system. Despite the threat that climate change represents, is possible to produce more food as is evidenced, for example, the worldwide in-creases in the average yield per year of corn, rice wheat, and soybean. How-ever, stresses such as temperature may have a negative impact on productivity. World grain yields decrease for each degree of increase in minimum global temperature. In addition, temperature increase induces other events such as the incidence of pests and diseases and damage to germplasm. This work fo-cuses on the perspective of food production in the world, addressed from five fundamental aspects: 2) Temperature in crop yield. 3) Stress factors cause financial losses. 4) Water use in Agriculture. 5) The urge to increase plant productivity against climate change, and finally 6) Plant diversity and conservation.

Annonaceous acetogenins enclose a large number of biological activities, among which the insecticidal stands out. Spodoptera frugiperda is a pest that affects corn crops among others and has a great capacity to develop resistance to traditional insecticides, which represents sufficient reasons for the search for new alternatives for their control. The objective of this study was to deter-mine the appropriate concentration and screening new natural insecticides against second instar larvae of S. frugiperda, under glasshouse conditions on Zea mays L. Natural products such as annonaceous acetogenins and some acetylated and methoxy methylated ACG derivatives and the commercial product Lambda-cyhalotrin (LC) were evaluated. The percent mortalities of S. frugiperda larvae in glasshouse conditions were recorded after 24, 48 and 72 h of treatment application. The results showed that the acetogenins tested were significantly (P < 0.05) different in relation to pest mortality than natural ACGs synergizes the insecticidal activity of the commercial product. Finding a new ecological alternative for insect control.

The waste of foodstuffs is increasing in the agri-food industries. This is reflected in the increasing volume of their waste. Food is thrown away on criteria that have nothing to do with its nutritional quality. In most cases, the criteria are shape, color and stains. In order to reduce this waste, a way of valorization was investigated. This paper focuses on waste reduction through feeding the Abidjan zoo animals with the unsold products of three agro-industries. The unsold products collected by the zoo were characterized over an 8-year period (2011 to 2019). Deaths and births were recorded. The food needs met by the unsold products harvested were evaluated and the economic gains estimated. The results showed that the food recovered by the Abidjan Zoo at SOCOCE contained 34.94% fruit, 38.58% vegetable and 23.47% meat products. At SCB and Coquivoire the donations are estimated at 2 tons of bananas and 1.5 tons of chickens (smoked and cold chicken) respectively. These donations allowed the Zoo to save 25.94% of its budget allocated to animal feed. The diversity of the food collected has a positive impact on the quality of life of the animals at the Zoo. This is reflected in an increase in the number of births from 0 to 12 per year and a decrease in mortality of 90%.

Water control is a major problem in crop production, particularly in fragile ecosystems such as the Sahel. Water is the most important factor in plant productivity. Many initiatives have been developed in this direction, including all methods of irrigation and water and soil conservation. The objective of this work is to assess the effectiveness of this amendment in crop production in the context of climate variability. The methodology is based on experimentation to statistically compare the natural biomass on a soil of silty-clay-sandy texture, divided into two blocks, one of which is amended with potassium polyacrylate and the other is not. This study showed that the wet and dry biomasses produced on soils with potassium polyacrylate are significantly higher than those produced on unamended soils at the 5% threshold. Based on these results, potassium polyacrylate may be a solution to recurrent dryness pockets. However, uncontrolled environmental testing is necessary to confirm these results.
