Abdurrahman Pirinç | Abdullah Özbilgin | Oğuzhan Kahraman | Esad Sami Polat
In this study, nutritional values of silages made from seed pumpkin residues were investigated. Pumpkin residues collected from Konya region were put into silo in vacuum sacks with various additives. As additives, straw, inoculant containing lactic acid bacteria or a mixture of both in certain proportions were used. After the silos were opened, their pH was determined and then samples were taken to determine the essential fatty acid compositions and nutrient analyses were done. Natural pumpkin (Group 1), natural pumpkin + inoculant (100ppm) (Group 2), withered pumpkin + 15% straw (Group 3), withered pumpkin + 15% straw + inoculant (100ppm) (Group 4) such that the fourth group is formed. Dry matter values of pumpkin groups are Group 1 7.89%, Group 2 6.62%, Group 3 12.22% and Group 4 12.25% respectively. Their pH is 3.78 in Group 1, 3.71 in Group 2, 3.86 in Group 3 and 3.82 in Group 4. The crude protein ratio in the experimental groups was determined in the highest Group 2 (14.97%) and the lowest in Group 3 (10.56%). NDF rate was determined in the highest group 4 (49.74%) and the lowest in Group 2 (28.51%). In addition, the highest ADF rate was determined in Group 4 (37.91%) and the lowest in Group 2 (24.90%). There was a statistically significant difference between the research groups in terms of ethanol content. Acetic acid and propionic acid content was found statistically significant between groups. As a result, when the pumpkin residues are silaged, it can be used as feed material in animal feeding. In addition, it can be said that pumpkin residues can be evaluated in different areas in the high amount of Ethanol content resulting from silage production.

Abdullah Beyaz | Serdar Özlü | Dilara Gerdan
The present study was focused on the design and implementation of an experimental recognition system for dirty chicken eggshell by using an image analysis technique. Image analysis based observation and evaluation techniques can be used efficiently and effectively for agricultural product quality control. Dirt stains on eggs are the result of mainly by feces (black to light brown stains), uric acid (white stains), yolk, and blood. The experimental system was used to obtain dark level images of dirty stains of chicken eggs owing to feces. For this aim, the dirty chicken eggs which have dirty parts were put under a webcam, and dirtiness degree was evaluated by using developed image analysis software at the LabVIEW platform. For the experiment, 100 clean and 100 dirty eggs were used to accurate the determination of dark stains. The results of the research showed that the designed experimental system pointed an accuracy of 99.8% at painted grade eggs. On the other hand, the accuracy of the differentiation of the dirt stains by feces was 98.5%. The developed system can be upgraded for developing egg sorting machines by presence-absence of dirty stains in eggshell.

Common bean (Phaseolus vulgaris L.) production is constrained majorly by drought and low soil fertility in Kenya. These limitations have never been adequately approached due to financial challenges and lack of better technology. A study was carried out in Kirinyaga and Embu Counties to evaluate the effects of tillage method and residual fertilizers on yield performance of dry bean. Dry bean was grown in the short rains season on plots preceded by fertilized maize (Zea mays L.) grown in the long rains season. The trials were laid out in a randomized complete block design with a split-plot arrangement. The tillage methods, NT+CR and CT-CR, where NT: No-tillage, CT: Conventional tillage, and CR: Crop residue, were assigned the main plot and residual fertilizers (NK, NP, PK, NPK, and NPK+CaMgZnBS) the subplots. The results showed that there was 35% and 46% more water retention under NT+CR than under CT-CR system in Embu and Kirinyaga sites, respectively. NT+CR produced higher biomass, more number of pods per plant, number of seeds per pod, and 1000-seed weight. Plots with residual NPK+ZnBMgCaS yielded higher biomass at 60 DAE, number of seeds per pod, 1000-seed weight and grain yield than plots with other treatments. The residual NPK+ZnBMgCaS and NPK treatments out yielded PK treatment by 600 kg ha-1 and 370 kg ha-1 (Embu) and by 710 kg ha-1 and 330 kg ha-1 (Kirinyaga), respectively. Based on these results, cultivation of dry bean on residual fertilizer nutrients solely or in combination with no-till and crop residue retention after maize harvest has the potential to improve the yields and food security among farmers in the region.

The aim of this study was to investigate the effect of mycorrhiza application on the vegetative development of blackberry cuttings grown under different irrigation regimens. The research was conducted between March-June 2019 in Akdeniz University, Faculty of Agriculture, Research and Application Area. Glomus etunicatium, obtained from Çukurova University Soil and Plant Nutrition Department was used as mycorrhizal fungal material and four different irrigation levels (40%, 60%, 80%, 100%) were applied in the experiment. In order to investigate the effects of the applications on the morphological properties of blackberry cuttings, shoot diameter, plant length, number of leaves and relationship of these variables with each other and flowering dates were determined. When the results were evaluated, it was determined that mycorrhiza application had a positive effect on the vegetative development of the plants. Significant differences were determined between the effects of different irrigation levels on the morphological development of plants. The highest average shoot length (62.08 cm), stem diameter (8.37 mm) and number of leaves (16.28 number/plant) were obtained from the S100 application, where full irrigations were performed. However, there was no statistically significant difference between S80 and S100 subjects in terms of shoot length and stem diameter, and S60, S80 and S100 subjects in terms of number of leaves.

Reports have indicated that lipid peroxidation is a key factor in soybean daddawa deterioration and Alliums are rich in antioxidants. The present study was carried out to investigate the preservative abilities of aqueous and ethanolic extracts of Onion (Allium cepa L) on stored soybean daddawa compared with Sodium Chloride treated samples. Soybean (Glycine max (L). Merr.) seeds fermented into soybean daddawa was preserved with both extracts (at 3, 5 and 7% concentration) and NaCl (at the concentrations of 0, 3 and 5%). The samples stored at 30±2°C for up to 14 days were analyzed for peroxide value (POV), free fatty acid (FFA), pH, titratable acidity (TTA), water absorption capacity (WAC) and fat absorption capacity (FAC). Type of solvent used in extraction did not have significant effect on all the storage indices. Extracts of Onion significantly lowered the POV, FFA and TTA generated in stored soybean daddawa. The pH of stored soybean daddawa samples treated with the NaCl and aqueous extract was not significantly affected while the ethanolic extract significantly reduced the pH from 8.26 – 8.34 to 5.72 – 5.89. The tested extracts lowered the WAC significantly while the FAC of treated soybean daddawa was not significantly affected compared to those treated with NaCl. Results of this study indicate that both extracts of Onion are more effective in lowering peroxidation in stored soybean daddawa and thus could be exploited for soybean daddawa preservation.

This study has been carried out to investigate that the effect of different levels of in ovo zinc, manganese and copper mineral mix injection on the hatchability and some tissue characteristics in the Japanese quail breeder eggs. In the study a total 400 Japanese quail breeder eggs which have similar weight have been randomly distributed to four different experimental groups: C as control non-injected (C), MinMix1 has been injected with 15+15+3 µg Zn-Mn-Cu mineral mix + 0.2 ml physiological serum per egg, MinMix2 has been injected with 30+30+6 µg Zn-Mn-Cu mineral mix + 0.2 ml physiological serum per egg and MinMix3 has been injected with 45+45+9 µg Zn-Mn-Cu mineral mix + 0.2 ml physiological serum per egg. The effect of treatment on hatchability, hatching weight and tibia weight, leg, beak and tibia lengths has been found to be unimportant. The yolk sac weight was lower in the injected groups compared to the control group, whereas the heart and liver weights, chick and wing lengths have significantly increased with the in ovo mineral mix injection. The hatching of chicks in the injected groups has started earlier than the control group and the hatchings of these groups were completed earlier, except for the MinMix3 group. These results demonstrated that in ovo injection with MinMix2 increased heart and liver weights and chick and wing lengths while in ovo mineral injection decreased yolk sac.
