The aim is to examine the response of maize to organic and inorganic fertilizer on soil under intensive continuous cultivation.  Initial soil samples were collected randomly from experimental plots and analyzed. The experiment was carried out using four treatments, organic,  inorganic, organic plus inorganic, and control with each replicated three times. Each plot has a dimension of 3m x 4m. Agronomic parameters observed  were plant height (cm), number of leaves (leaf area index, LAI), stover’s weight, ear weight, and yield of grain. After harvesting, soil samples were  collected to measure changes in soil properties. Calcium, magnesium, and sodium improved significantly after the application of organic and inorganic -  compared to other treatments. The result shows that plot treated with organic plus inorganic fertilizer (poultry manure + NPK) had the highest yield of  1.03t/ha compared to inorganic (NPK) 0.87t/ha, organic (poultry manure) 0.71t/ha and control which had no treatment has the least yield of 0.15t/ha.  Therefore, inorganic plus organic were recommended for optimum and sustainable production on degraded soil.  ","PeriodicalId":11865,"journal":{"name":"European Journal of Agriculture and Food Sciences","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84347529","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}

Bacopa floribunda leaves were  plucked, destalked, withered, rolled, fermented/oxidized, milled, dried, cooled and packaged. The antinutrients phytate, saponin and tannin content of B.  floribunda leaves reduced significantly (P ˂ 0.05) after processing into BFHT. The mineral ratios and molar ratios of minerals BFHT were within the critical  values making them available for absorption. BFHT exhibited a very high and significant (P ˂ 0.05) total phenolics (60.08 mg GAE/g), total flavonoids  (12.96 mg QE/g) and reducing power (50.38mg AAE/g). The scavenging activities of BFHT extract against DPPH and Nitric oxide (NO) was significantly (P ˂  0.05) higher than freshly harvested B. floribunda leaves.

One hundred and forty-eighty farmers were randomly selected using interview schedule. Also, focus group  discussions were conducted with 137 participants. Pairwise comparison was used to evaluate the difference between the proportion of household heads  who used the videos to learn and those who did not use the videos. The study revealed that farmers have similar perception of climate change and  related impacts in video-villages and in non-video-villages. However, the study revealed farmers’ observation of climate change and related impacts are  influenced by gender, with men perceiving more climate change and related impacts than women. In non-video villages, few respondents adopted crop  rotation, intercropping, crop diversification, and improved short-cycle seed varieties as climate change adaptation strategies. Videos contribute more to  the adoption of crop rotation, intercropping and fertilizer application for men than for women. Videos on accounting (managing money) enable more  women than men to enhance their cost-benefit evaluation practices for income improvement. During the interviews, women farmers in video-villages  were eager to demonstrate their knowledge about cost-benefit evaluation. Furthermore, the yield of sorghum, cassava and maize is higher in video-  villages than in non-video-villages. Thus, using videos as an extension tool is suitable for knowledge development and leads to the high adoption of  climate-smart agricultural practices for food security. ","PeriodicalId":11865,"journal":{"name":"European Journal of Agriculture and Food Sciences","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85448854","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}

This study examined  determinants of food waste among households in Osogbo Metropolis, Osun state, Nigeria. Multistage sampling procedure was used to select one  hundred and twenty (120) respondents from the study area. Data were collected with structured interview schedule. Frequency counts, means,  percentages, and multiple regression analysis were the major statistical tools employed in data analysis. Results of descriptive analysis of the  socioeconomic characteristics reveals that majority of the respondents were middle aged, married, female public officers, with averaged sized family.  Protein from plant sources and carbohydrate are the most wasted household food items in the households. Protein from plant sources and carbohydrate  are the most wasted household food items in the households. Epileptic electricity supply is a major reason for household food wastages,  while refrigeration is the most widely used method of preservation among the households. The study concluded that significant quantity of food is  wasted among the households. Household size, household food expenditure, the quantity of food consumption, and frequency of food consumption are  significant factors influencing the level of households’ food waste in the study area.

The design  was RCBD with four replications and the experiment had two factors; Pymarc rates: P0(control), P1(250Kg ha-1 NPK), P2(10 tons ha-1 pymarc+250  Kg ha-1 NPK), P3(15 tons ha-1 pymarc+250Kg ha-1 NPK) and P4(20 tons ha-1 pymarc+250Kg ha-1 NPK) and spacing levels: S1(40cm x15cm), S2(40cm x  20cm) and S3(40cm x 30cm).
