Different growth parameters, chemical constituent and yield were determined in this study. The results indicated that organic fertilized plants achieved higher values of different growth parameters (plant height, number of branches, plant leaf lets blade area and dry weight / plant) and yield and its components (number of pods / plant, no of seeds / pod, weight of seeds / pod, weight of 100 seeds and weight of seeds / plant). The best results were obtained when the plants were fertilized with high rate of poultry manure (8 tons) and NPK fertilizers (50 kg ammonium nitrate 33.5% + 200 kg superphosphate 15.5% + 50 kg potassium Sulphate 48%). The present results also show that the concentration of chlorophyll.

Introduction Broad bean (Vicia faba L.) is a famous winter leguminous crops in Iraq. It is considered as a good source of vegetarian protein for human consumption, and it is cultivated in crop rotations to improve soil properties [1]. Application of chemical and organic fertilizers is an essential process in plant management. Adequate fertilizers led to increase the crop yields, improves the nutrient element concentration in plant tissue and soil macro and micro nutrient status. Chemical fertilizers are expensive and have harmful effects on the environment [2], therefore recommended the addition of organic matter (animals manure) as an alternative to chemical fertilizers [3]. The addition of organic fertilizers efficiently ensures high production and continuous crops by improving soil properties and increase roots development and soil microorganism's activity [4&5]. Some researchers reported that application of organic manure (poultry or farmyard manure) increased pod yield, N, P, Ca, Ma, Zn and Cu concentration and their uptake plants [6,7,8,9,10,11,12,13,14&15]. Because of the importance effect of fertilizer types, especially organic fertilizers in influencing the quantity and quality of yield as well as external and physiological aspects of plant growth, this study was carried out to compare the effect of some organic fertilizers (poultry or farmyard manure) in combination with chemical fertili","PeriodicalId":171140,"journal":{"name":"Sustainable Food Production","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132784609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study therefore investigates the effect of different starter culture on the amino and fatty acid profile of Parkia biglobosa seed fermented to produce iru. Starter culture of Lactobacillus plantarum, Bacillus subtilis and Leuconostoc mesenteroides were used to ferment Parkia biglobosa seeds. The bacterial load increased from 0.00 log10cfu/g in boiled raw sample to 8.67 log10cfu/g in naturally fermented sample. Fermentation significantly (P<0.05) increased the quantity of the amino acids in fermented samples. Aspartic acid (25.85 g/100g) and linoleic acid (42.99 %) were the highest amino and fatty acids respectively in the fermented samples. The result from this study reveals that fermentation significantly increase the amino and fatty acid profile of Parkia biglobosa fermented to produce iru, a Nigerian condiment. Introduction Fermented food form an integral part of the African diet. These foods are generally fermented as a method of preservation, to increase the safety and also to produce a lot of varieties [1]. Fermentation has been reported to also increase the nutritional value of the fermented product, increase the digestibility and also degrade hazardous components in the raw materials. In the African countries, rural dwellers who cannot afford animal products such as meat or dairy, which supplies the needed protein requirement in diets rely on fermented legumes [2, 3, 4]. Legumes has been providing the needed daily requirement of protein for these rural population because of the reduced cost of production, less difficult to process and the high energy value supplied [5]. Among the leguminous plants used by African population, Parkia biglobosa seeds had gained popularity. It is a perennial tree belonging to the family Leguminoseae and sub-family Mimosadeae. The seeds of Parkia biglobosa are fermented into ‘iru’ which is an indigenous fermented food condiment among the Yoruba people of Western Nigeria in West Africa [6]. The production process is usually on a small scale house-hold basis under varying condition [7]. The production of iru involve soaking the Parkia biglobosa seeds for about 30 minutes before cooking [1]. The cooked seeds were dehalled and cotyledon washed and recook, the cotyledon were then packed in containers for fermentation to take place [1, 2, 4, 6, 7]. However, the optimum condition for the fermentation procedure has been documented to be 35 oC for 36 hours [8]. The production of ‘iru’ is left to chance inoculation. This often cause variation in the product. The presence of varying array of bacteria may also be a factor that leads to contaminating organisms producing secondary metabolites which often lead to inconsistency in the final product. Elemo et al. [9] had earlier reported that the seeds of Parkia biglobosa could be a good source of amino and fatty acids. Both fatty acids and amino acids plays ","PeriodicalId":171140,"journal":{"name":"Sustainable Food Production","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128713451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of heat treatments (roasting, boiling and autoclaving) on the physical, nutritional and functional properties of in-shell and shelled peanut (Arachis hypogaea) was determined. Unprocessed shelled peanut served as the control. Nutrient and anti-nutrient compositions of peanut samples were determined by standard methods, while physical (colour) and functional properties were also carried out. Analysis of variance was used to analyze the treatment groups and Duncan's multiple range tests to determine significant difference at p≤0.05. The result of proximate composition revealed that raw peanut had protein (32.7%), ash (1.37%), fibre (5.15%), fat (42.9%) and carbohydrate (12.1%). However, processing methods significantly increased the fat and ash contents. Peanut is high in calcium, magnesium and potassium but low in iron and zinc; processing significantly increased the elemental concentration of peanut. Phytate, tannin, oxalate, alkaloid, trypsin inhibitor and flavonoid were determined in the peanut samples and all were significantly affected by the processing method employed. However, boiling of shelled peanut was more effective in reducing the anti-nutrients than roasting and autoclaving. The aflatoxin concentration was in a range of 2.06-8.05ppb. Shelled peanuts subjected to the processing methods had lower aflatoxin levels compared with in-shell processed peanuts. There exist variation in bulk densities (packed and loosed), water and oil absorption capacities as a result of processing method employed. The colour of peanut was significantly affected by the processing method. In general, processing of shelled peanut resulted in flour with better nutritional quality and functionality than in-shell peanut. The findings showed that boiling has proved to be an efficient method in processing of peanut.","PeriodicalId":171140,"journal":{"name":"Sustainable Food Production","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128441997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
