Three groups with 3 replications were formed and a commercial aquarium fish feed having 47.5% crude protein was added as the ammonia factor in three different concentrations (0.2 g feed/500 ml tap water, 0.4 g/500 ml tap water, 0.6 g/500 ml tap water). Ammonia increases resulted from 3 different amounts of feed were monitored for 7 days. At the end of this period, the adsorbent mixture, which has water-regulating properties, was added to the experimental groups at a ratio of 1:2 (clinoptilolite:leonardite) to remove ammonia, which is harmful for aquatic organisms, and ammonia decreases was determined at regular intervals. NH3 value reached its highest (0.7 mg/L) at the end of the stage where the ammonia values from the feed were measured. After this period, it started to decrease with the addition of natural adsorbents (mixed clinoptilolite-leonardite) and the lowest ammonia value was determined at the end of the 6th measurement (0.07 mg/L). As a result of this study, it was determined that the clinoptilolite:leonardite mixture has a positive influence on ammonia removal in freshwater aquariums.","PeriodicalId":229702,"journal":{"name":"Journal of Agricultural Production","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129083042","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}

Moreover, plant growth is largely dependent on the physicochemical properties of the growing media. The purpose of this study was to see how different growing media and shade houses affected strawberry plant growth, yield, and quality attributes. The experimental treatments include net house, UV poly shade house, and open field (control) conditions; and three different growing media i.e., 50% soil + 50% cowdung, 50% soil + 50% vermicompost, and 50% soil + 50% cocopeat were studied. According to the findings, strawberries grown in a net house with cocopeat substrate had the highest chlorophyll content (SPAD value) (46.1), fruit yield (289.16 g plant-1), total soluble solid (8.0%), reducing sugar (8.75 mg g-1) and total anthocyanin (30.80 mg 100 g-1). In contrast, fruits grown under UV poly shed with cocopeat substrate exhibited increased plant height (20.33 cm) and ascorbic acid (46.94 mg 100 g-1). Vermicompost based growing media showed no satisfactory improvement in the reproductive growth characteristics of strawberry plants. Therefore, cocopeat based growing media and net house shade may be recommended to obtain better strawberry yield and quality.","PeriodicalId":229702,"journal":{"name":"Journal of Agricultural Production","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129211406","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 was conducted to find a suitable ARIMA model for forecasting Uganda’s beef and cattle milk production using annual time series data from 1961 to 2020, extracted from the Food and Agriculture Organization Corporate Statistical Database (FAOSTAT). Following patterns of the Autocorrelation Function and Partial Autocorrelation Function plots of the differenced series, 4 tentative ARIMA models were identified for milk production, i.e., ARIMA (0,1,0), ARIMA (1,1,0), ARIMA (0,1,1), and ARIMA (1,1,1). While 3 tentative ARIMA models were identified for beef production, i.e., ARIMA (1,1,1), ARIMA (1,1,0), and ARIMA (0,1,1). ARIMA (0,1,0) model was selected to be the most suitable for forecasting cattle milk production because it had the smallest MAPE and Normalized BIC values. On the other hand, ARIMA (1,1,0) was selected to be the best model for forecasting beef production because it had the smallest normalized BIC value and a significant coefficient of the autoregressive component. Forecasts show that milk production will increase at an annual average rate of 1.63%, while beef production will increase at an annual average rate of 0.39% in the five-year forecast period (2021-2025). These findings are important in designing strategies to improve the beef and dairy livestock sub-sectors in Uganda.","PeriodicalId":229702,"journal":{"name":"Journal of Agricultural Production","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134293938","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}

Using a completely randomized block design, seeds of the okra accessions were planted with three replicates each. During the developmental stage, the morphological features of the accessions were observed and recorded according to the standard descriptor for the crop. Morphologically, all the accessions exhibited a degree of similarities, albeit, at maturity, the leaf, plant height, leaf colour, and leaf shape became distinct. A cluster of the phenotypic characterization was observed at a 3.74 level of coefficient of similarity with two distinct clusters, which were predicted to be A. esculentus and A. caillei. The percentage variance of the two principal components was 55.12% and 22.69% with corresponding Eigenvalues of 4.11 and 1.69, respectively. Results of the RBCL analysis revealed genetic variability at a 0.80 level of coefficient of similarity. Two distinguishable clusters were observed. Both morphometric and genotyping results suggest that variations exist among and within the seven accessions. In conclusion, there is a need to frequently evaluate plant genetic resources held in gene banks as they may not reflect the whole range of diversity inherent in the species.","PeriodicalId":229702,"journal":{"name":"Journal of Agricultural Production","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122793142","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 egg is the cheapest and most affordable animal protein source in Nigeria, but its production has not been able to match the increasing demand capacity. Premised on the above facts and to identify ways to intensify egg production, the study was specifically designed to examine the trend in egg production and establish the relationship between egg production and selected macroeconomic fundamentals in addition to other variables in Nigeria. The study used time series data from the period 1961 to 2020. The data were sourced from the Food and Agricultural Organization (FAO), the World Bank, and the Central Bank of Nigeria. The Augmented Dickey-Fuller unit root test and ADF-GLS unit root test were used to confirm the stability of the series. The Engle-Granger two-step technique was used to test for the cointegration of the series. The empirical finding showed that the amount of credit disbursed to the agricultural sector, per capita income, and the quantity of maize and chicken meat produced are positive determinants of egg production in both long and short-run periods. In contrast, the consumer price index (inflation rate) relates negatively in both periods to egg production. To upsurge egg production in the country, it is recommended that more credit facilities be injected into the agricultural sector. At the same time, the inflation rate is maintained at a minimal rate in the country.","PeriodicalId":229702,"journal":{"name":"Journal of Agricultural Production","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123280944","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}

With approximately 600 000 tons of chemical fertilizer consumption in 2021, it is the province with the most fertilizer consumption in Turkey. This causes some negative and high environmental risks such as salinization in the soil, heavy metal (HM) accumulation, deterioration of nutrient balance, damage to microorganism activity, and formation of eutrophication in the region. The objective of this study was to determine the HMs (Zn, Ni, Mn, Cu, Mo, Pb, Cd) concentrations of the soils and some commercial fertilizers overused, and evaluate their interactions with soil properties. The average values of HM concentration of the soil are as follows; 32.65 and 46.88 mg kg-1 Zn; 649.03 and 730.58 mg kg-1 Mn; 79.86 and 95.54 mg kg-1 Ni; 0.15 to 0.27 mg kg-1 Cd; 0.26 and 0.97 mg kg-1 Mo; 8.54 and 18.67 mg kg-1 Pb; 19.45-25.37 mg kg-1 Cu. HM contents of some fertilizers were found to be very high in this study. This causes an increase in the HM concentration in the soil. HMs concentrations of several soil samples exceeded the threshold level of Europe standards except for Ni, Mo, and Mn. Study results can help the authorities to develop effective fertilizer management strategies for the Harran Plain, which has once again revealed the necessity of applying agricultural activities such as fertilization with a fertilization program prepared under expert control according to the results of soil analysis.","PeriodicalId":229702,"journal":{"name":"Journal of Agricultural Production","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127404048","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}

Therefore, this study was emphasized to determine combining ability and the association between traits among themselves and yield. The experiment was conducted at Haramaya University Research Station (Raare) for two years (2018 and 2019) using 4x7 alpha-lattice design with three replications. Pooled analysis of variance revealed highly significant (p≤0.01) variations among crosses for grain yield and related traits. According to the result of combining ability analysis, parental line L3 was identified as a good general combiner for grain yield, ear diameter, 1000-kernel weight, and days to maturity. Similarly; L1, L2, and L8 proved as the best general combiner for number of kernels per row. Crosses L1×L6, L3×L5, L4×L6, L4×L8, and L5×L7 were found good specific combiners for 1000-kernel weight. Furthermore, the cross L5×L6 was the best specific combiner for ear diameter, whereas L4×L7 for both number of kernels per row and 1000-kernel weight. Likewise, the crosses L1×L5, L3×L8, L6×L7, and L7×L8 were identified as the best specific combiner towards earliness. Moreover, thousand kernel weight showed significant positive correlation with grain yield, conversely, days to anthesis, days to silking, ear aspect, and Puccinia sorghi exhibited significant negative correlation with grain yield at genotypic and phenotypic levels. Ear length, 1000-kernel weight, number of kernel rows per ear, and Turcicum leaf blight had positive direct effect on grain yield at genotypic and phenotypic level. In general, the result presented in the study might be useful for further breeding process to improve the productivity of maize.","PeriodicalId":229702,"journal":{"name":"Journal of Agricultural Production","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122496061","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}
