Abstract:
Aims - The farming intensification in Sub-Saharan Africa induced soil fertility and crop yields depletion such as cassava, a main food and an important source of income of farmers in Central Africa Republic. To transcend the soil fertility depletion and improve cassava yield, LaSBAD has initiate a study focused on the mineral fertilizers of cassava crops. Methods - Four types of fertilizer were tested: the urea (Co(NH2)2), the potassium sulfate (K2SO4), the potassium chloride (KCl) and the triple superphosphate (TSP). The methodology consisted in the physical and chemical analysis of soil, the cultivation, the application of mineral fertilizers and the harvest of cassava after 12 months. Additionally, the evaluation of the organoleptic propriety of raw tubers and cassava balls after the use of fertlizers were achieved throughout semi-strucrured interviews. Results - The contribution of nitrogen and phosphorus has increased very significantly cassava yield from 18.70 to 40.20 t/ha respectively for the control treatment (T0) and the best treatment obtained (T10). A significant interaction was observed between nitrogen (N) and potassium (K) inputs on yields. The increasing doses of potassium as potassium chloride (KCl) had reduced cassava plant growth and yield. According to respondents, the organoleptic proprieties of cassava were remain quite unchangeable by mineral fertilizers. Conclusion - The application of mineral fertilizer improved cassava yield and did not affected the organoleptic quality of the raw tubers and cassava ball. Nevertheless, further studies are needed to prevent soil degradation, namely the potential use of termite nest as natural fertilizers and legumes in association or rotation with other crops.

Abstract:
ABSTRACT Agroindustrial residues, such as cassava wastewater, have been used as soil fertilizers, reducing environmental pollution and recovering nutrients. The objective of this work was to evaluate production and morphological components and oil yield of sunflower (Helianthus annuus), hybrid Helio-250, fertilized with cassava wastewater. The experiment was conducted at the Experimental Station of the Instituto Agronomico de Pernambuco, Vitória de Santo Antão, State of Pernambuco, Brazil. A randomized block experimental design was used, with six cassava wastewater rates (0, 8.5, 17.0, 34.0, 68.0 and 136 m3 ha-1) and four replications. The variables evaluated were shoot fresh and dry weight, capitulum fresh and dry weight, capitulum diameter, seed yield, oil yield and seed oil content. The use cassava wastewater as soil fertilizer improved the production and morphological variables evaluated, except the seed oil content, which decreased with application of cassava wastewater rates above 25 m3 ha-1.

Abstract:
Superabsorbents starches (SASs) were synthesized and characterized starting from native corn starch, bitter cassava and sweet cassava by graft copolymerization with itaconic acid. Additionally, their swelling behavior was studied both in water and in buffer solutions with different pHs and saline solutions. Their applicability was tested as environmentally friendly fertilizers in the absorption and release of urea, potassium nitrate and ammonium nitrate at different concentrations of fertilizers. The values of swelling at the equilibrium (H∞) in water and different media of the graft copolymers demonstrated their superabsorbent capacity, polyelectrolyte behavior, and smart response to environmental stimuli. The percentage of fertilizer absorbed and released from the SASs was a function of the initial concentration of the fertilizer in the medium. The loading and release of SASs were depended on the initial concentration of the fertilizer in the medium as well as the nature, structure, and morphology of the starch used.

Abstract:
A study was conducted at Kyambogo University Farm in randomized complete block design with three replications to assess the effect of NPK (17:17:17) fertilizer on the growth and tuber yields of two newly developed cassava (Manihot esculenta Crantz) varieties, NAROCASS 1 and NASE 14. Cassava varieties were assigned to the main plots, while fertilizer rates (zero/control, 200, 400, 600 kg/ha) were sub-plots. Fertilizer was applied in two splits, at planting and four months after planting. Fertilizer application significantly (P<0.05) increased the cassava stem heights to first branching and at harvest, and the number of stems per plant when compared with the control treatments. Mean stem heights to first branching and at harvest of plants that received NPK were higher than those of the respective control treatments by 62.8 and 70.5% for NAROCASS 1, and 57.0 and 76.5% for NASE 14, respectively. Fertilizer rate of 400 kg/ha significantly increased the lengths, numbers of tubers and tuber yields per plant when compared with the control treatments. Mean lengths, numbers of tubers and tuber yields of plants that received NPK were higher than those of respective control treatments by 48.2, 36.9 and 68.3% for NAROCASS 1, and 39.9, 50.5 and 67.6% for NASE 14, respectively. Therefore, to achieve optimum tuber yields of newly developed cassava varieties, farmers should integrate NPK fertilizer application into already existing management practices, particularly the use of high quality planting materials and integrated pest, disease and weed management. However, government ministries concerned should ensure that inorganic fertilizers are readily accessible and affordable to farmers.

Abstract:
This study aims to propose an industrial-agricultural symbiosis model that applies the closed sloop eco-technical solutions for cassava starch production towards sustainable development. This study applies the AHP method to analyze nine alternatives and determines the best one based on 17 specific criteria for the typical cassava starch production plant in Tay Ninh province. The chosen model has 12 losed sloop solutions and can save about 40% groundwater, hundreds of cubic metre of water for irrigation in agriculture (to meet hundreds of hectares of crops), limit the lack of water in the dry season and water regulation from the Dau Tieng lake and reduce from 19-73% emissions from traffic,... Wastewater after Biogas is diluted in proportion for cassava is 28l wastewater/49l of clean water and the rubber tree is 8,5l of wastewater/7l of clean water and sugar-apple is 20l wastewater/20l of clean water wasto spray as a natural leaf fertilizer, limiting the use of NPK chemical fertilizers. Some indicators of wastewater after treatment show that it is suitable for use as fertilizer but suitable for nutrient development in the soil and increase nitrogen for plant development, reducing the cost of using stimulating fertilizers. In addition, production wastewater with high cyanide levels is also considered to dilute according to certain proportions as natural insecticidal drugs. These results show that industrial-agricultural symbiosis model bring great enviromental benifits for cassava starch industry and can be replicated in the future.

Abstract:
This study aimed to evaluate the effect of compost from chicken manure, NPK fertilizer and the mixture of both fertilizers on agronomic parameters of four varieties of cassava (Yacé, Bonoua, Six mois and Alleda agba) in Côte d’Ivoire. The field experiment was carried out under a randomized complete block design with three replicates on a ferralitic soil during two season-cycles. The results showed that the different fertilizers stimulated plants growth and tuberous roots production. The highest number of stems (3) and leaves (66) was obtained with the mixture of NPK and compost applied on the variety “Bonoua”. All varieties that received the compost mixed with NPK produced more leaves with a dominance of the Bonoua variety (65.57). The highest number of tuberous roots (5.58), the heaviest weight per root (6.13 kg) and the highest yield (61.37 t/ha) were obtained while using the mixture of compost and NPK as fertilizer and “Bonoua” as variety. Thus, mixing compost from chicken manure and NPK can be recommended to improve cassava productivity in Côte d'Ivoire on a ferralitic soil.

ABSTRACT The utilization of organic wastes in agriculture is an alternative that can reduce the amounts of mineral fertilizers applied to the soil. The aim of this study was to evaluate the accumulation of macronutrients in sunflower cv. 'Hélio 250' fertilized with cassava wastewater. The experiment was conducted in randomized block design, with six treatments (0; 8.5; 17; 34; 68 and 136 m3 ha-1 of cassava wastewater) and four replications. The accumulation of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S) were evaluated in leaves, stem, capitulum and achenes. The cassava wastewater dose of 136 m3 ha-1 promoted the greatest accumulation of all evaluated nutrients. The pattern of macronutrients accumulation occurred in the following order: leaves - Ca > K > N > Mg > S > P; stem - K > Ca > Mg > N > P > S; capitulum - N > K > P > Mg > Ca > S; and achenes - N > P > K > Mg > S > Ca. The extraction of nutrients by whole sunflower plants occurred in the following order: N > K > Ca > Mg > P > S. Cassava wastewater provided appropriate concentrations of N, P, K, Ca, Mg and S; therefore, it has potential as an organic fertilizer for the studied sunflower cultivar.

Abstract:
Fecal sludge (FS) contains significant amounts of plant nutrients and organic matter although it also contains pathogens. Therefore, FS can be used as fertilizer after proper sanitization. This study was designed to test dried fecal sludge (DFS)-based pellet fertilizers on maize cultivation. The DFS fertilizers were produced by composting, co-composting with sawdust, or irradiated by gamma-irradiation, and then nitrogen-enriched and pelletized using gelatinized or gamma-irradiated cassava starch. These DFS pellet fertilizers were compared to each other and to no-fertilization, mineral fertilizer, and agro-industrial waste compost. The fertilizer applications were 150 or 210 kgN/ha. Maize was cultivated in pots containing Cambisol and Ferric Lixisol growth media. The EC-SDFS-PG pellet (DFS + sawdust co-composted, enriched with nitrogen and pelletized) at a rate of 210 kgN/ha produced the highest maize yield (4.4 ton/ha) among all other treatments, while mineral fertilizer produced 3.9 ton/ha. It is concluded that the EC-SDFS-PG pellet produces similar or higher maize yields than mineral fertilizer and more than the agro-industrial compost in both growth media types.

Abstract:
Phosphorus uptake cassava (Manihot esculanta Crantz) were tested using on thirty-six plants per plot under dryland conditions at four different sites selected Bioresource group 1 (BRG 1) of northern KwaZulu-Natal of South Africa, which is described as Moist, Coastal Forest, Thorn and Palm veld, exhibiting sub-tropical characteristics. Soils in this region are very low in Phosphorus (P) due to high fixation by iron and aluminium oxides. With its high root yields coupled with efficient nutrients miner, cassava removes large quantities of N, P, K and Mg. With the ever-increasing prices of P fertilizer, which impact on the socio-economic livelihood of smallscale farmers, there is the need to look into improving the P uptake by the crop by alternative means apart from using mineral fertilizers. The objective of this study was to investigate the use of Arbuscular Mycorrhizal Fungi (AMF) to improve P uptake by cassava in agricultural soils. Laboratory studies were conducted at Soil Fertility and Analytical Services in Cedara (Pietermaritzburg). A Latin Square design (LSD) was used. Four treatments used were Untreated (Control), P-fertilizer, AMF, and P + AMF. Correlation and path-coefficient (probabilities) were computed. The P + AMF were significantly (p<0.05) taller than those in P-fertilizer treatment plots but were significantly (p<0.05) similar to those in Control and AMF-treated plots. Percent leaf P was statistically similar at the four sites with grand mean of 0.4%. Adding AMF and P+AMF to the soil substantially increased leaf P concentration to 0.5%. Tubers collected from P+AMF-treated plots were significantly (p<0.05) the longest, while those from Control plots were the shortest. P, and AMF-treated plots increased tuber length relative to the Control. All soil treatments significantly (p<0.05) increased tuber yields over the Control-treatment plots. However, AMF and P+AMF treated plots were significantly higher than P and control plots. This study suggests that using AMF or P+AMF can improve cassava yield as compared P alone or control – untreated cassava plants. Cassava producers in northern KwaZulu- Natal should consider using AMF or P+AMF to optimize tuber yield. A further study into the economic implications of the use of AMF is recommended.

Abstract:
Cassava is a source of carbohydrates to more than 200 million people in Sub-Saharan Africa, even though its production is 6–8 t ha−1, which is below the highest world production of 36.4 t ha−1 in India. To address this yield gap and increase cassava’s availability, affordability, and adequacy, intensive but sustainable production is important. Additionally, being an emerging raw material in the animal feeds, pharmaceutical, beer industries etc., only increases its demand, however the current production levels cannot effectively sustain this. Therefore, this paper reviews: improvement in cassava yields per area under fertigation and banding of fertilizers, a common practice among many farmers; the advantage of fertilizer application on starch of the storage roots, which is the fundamental ingredient in most industries using cassava as a raw material; and the climate smart technologies for intensive sustainable cassava production. In the end, this review enhances knowledge about fertilizer application to cassava, both banding and fertigation, and expounds on effective intensive sustainable climate-smart production strategies.

Abstract:
The livestock farming industry is a strategic industry and has a very important potential for the advancement of the agricultural industry. The livestock farming industry is an industry that plays a role in providing protein food for most of the world’s population. Not only as a food provider, but also having a very large contribution to the progress of agricultural cultivation in the world. The livestock industry contributes part of the needs of the agricultural industry through the provision of environmentally friendly organic fertilizers. The integration of the livestock farming industry and the agricultural industry is a mutually supportive system. The integration of plants with livestock is basically an agricultural system characterized by a close relationship between plant and livestock components in a farm in a certain area. The bio-mass waste products from the agricultural industry can be used as a source of animal feed or as raw material for compost. The combination of the livestock industry with the agricultural industry provides enormous economic value for the development of the livestock and agricultural sectors. In Indonesia, the concept of integration between the livestock industry and the agricultural industry has been proven to improve the standard of living and economic status of the community. Some important materials will be discussed in more depth in this paper, including: (1) integration between livestock and rice, (2) integration between goats and cacao plants, (3) integration of livestock with oil palm, (4) integration of ruminants with cassava plants, and (5) integration of cattle with horticultural crops. Utilization of livestock and agricultural waste can reduce environmental burdens. Livestock farming industrial waste in the form of manure can be combined with agricultural wastes. This waste can be used as raw material for organic fertilizers which can be used as a fertilizer provider to support the cultivation of food crops, horticulture and plantations. The development of livestock in an area can encourage farmers to fill their vacant land to be planted with forage. Guidance efforts that will be carried out will be oriented towards land conservation. This is done through the arrangement of forage planting. Therefore, this will have a positive impact on increasing forage production. This effort will ultimately support the improvement of feeding patterns, proper land arrangement and being able to reduce the rate of erosion. The existence of livestock will add a source of manure. This is certainly synonymous with increasing land fertility which can provide business opportunities in optimizing land use diversification. The role of livestock in the livestock industry is the main support and complement in the system of integration in the livestock industry-agricultural industry.

"of control. The state of Queensland has generous expertise in this area, with the CSIRO Division of Entomology – Lands Department group in Brisbane boasting spectacular success against Salvinia and Eichhornia, and near the reservoir at James Cook University a USDA unit was involved in successes with the Tennessee Valley Authority (TVA) (see Chapter 12) using a range of stem-boring and leaf-mining insects (Balciunas et al. 1993). One might consider the herbivorous grass carp Ctenopharyngodon idella, originally from China, more as a harvester than a biological control agent. This fish grazes on submerged weeds such as Hydrilla, Myriophyllum, Chara, Potamogeton and Ceratophyllum, and at stocking rates of 75 fish/ha control is rapidly achieved. Some introductions in the USA have resulted in removal of all vegetation (Leslie et al. 1987), and in the Australian context the use of sterile (triploid) fish (Cassani and Canton 1985) could be the only consideration. However, in view of the damage already done by grass carp to some inland waterways in Australia, it is suspected that this option would be greeted with horror. Mechanical control involves the physical removal of weeds from a problem area and is useful in situations where the use of herbicides is not practical or poses risks to human health or the environment. Mobile harvesters sever, lift and carry plants to the shore. Most are intended for harvesting submerged plants, though some have been designed or adapted to harvest floating plants. Handling the harvested weed is a problem because of their enormous water content, therefore choppers are often incorporated into harvesting machinery design. However, many mechanical harvesters have a small capacity and the process of disposing of harvested plant material is time-consuming. Any material that remains may affect water quality during the decay process by depleting the water of oxygen. Furthermore, nutrients released by decay may cause algal blooms (Mitchell 1978). Another disadvantage of mechanical removal is that disturbance often promotes rapid new growth and germination of seed, and encourages the spread of weed by fragmentation. Some direct uses of macrophytes include the following: livestock food; protein extraction; manufacture of yeast; production of alcohol and other by-products; the formation of composts, mulches and fertilizers; and use for methane generation (Williams 1977). Herbicides either kill on contact, or after translocation through the plant. Some are residual and retain their toxicity for a period of time. Where herbicides are used for control of plants, some contamination of the water is inevitable (Bill 1977). The degree of contamination depends on the toxicity of the material, its fate and persistence in the water, the concentration used and the main purpose served by the water. After chemical defoliation of aquatic vegetation, the masses of decaying organic debris produced can interfere with fish production. Several factors must be taken into account when selecting and adapting herbicides for aquatic purposes, including: type of water use; toxicity of the herbicide to humans, fish, stock, and wildlife; rate of disappearance of residues, species affected and duration of control; concentration of herbicide; and cost (Bill 1977). The TVA has successfully used EPA-approved herbicides such as Endothall, Diquat, Fluridone and Komeen against Hydrilla (Burns et al. 1992), and a list of approved." In Water Resources, 153–54.
