In this study, some agricultural and industrial organic wastes of agricultural sector are composted, as different compositions, to see whether they are usable as agricultural aids. To this end, apple juice factory waste (AW), cigarette factory waste (TW), leather processing factory waste (LW), organic wastes, namely wheat stalk (WW) and corn stalk (CW) material are used as composted material. Indore method of composting process was adopted; seven different compositions prepared from the aforementioned organic wastes were prepared. Laboratory experiments were carried out in conditions according to a pattern of coincidence plot experiment that was carried out by three replications. Prepared at room temperature, the mixtures (20-25 degrees C) were left to decompose for six months. Compost mixtures were mixed carefully every 10 to 15 days. Finally after 6 months compost mixtures were found to be fully composted. Obtained 7 different composts, yield analysis were determined and the effects of these mixtures on soil when applied in certain proportions in previously unused pots and on oat plant (Avena sativa L.) which was cultivated were determined. Plants were allowed to grow for a period of 45 days and then they were harvested to determine their dry weight and N, P, K, Fe, Cu, Zn contents. Results of the statistical analysis in terms of variance analysis and Duncan test were obtained. According to the results; N, P, K, Fe, Cu, Zn and Mn contents of seven different compost mixtures were found to be between 4.03 and 9.24 g kg(-1); 0.09 and 0.92 g kg(-1); 10.0 and 24.2 and g kg(-1); 5.3 and 14.2 mg kg(-1); 1.50 and 2.80 mg kg-1; 6.20 and 12.3 mg kg(-1); 19.7 and 27.2 mg kg(-1), respectively. Electrical conductivity of seven different compost mixtures was measured between 1,750 and 11,100 mu mhos cm(-1); pH was found to be between 6.85 and 8.32 and C/N was detected to be between 8.9 and 28.2. Compared to the control, all seven compost mixtures were found to increase plant yield and this increase was found to be between 6% and 45%. Based on the results, all compost mixtures, especially three compost mixtures (since they gave statistically significant difference), were found to increase soil fertility as well as plant yield being as useful in agriculture.eninfo:eu-repo/semantics/closedAccessCompostingagricultural wastesindustrial organic wastesoat plantyieldArticle1441827WOS:000409881500004N/A
