In vitro Propagation of Banana (Musa paradisiaca L.) Plant Using Shoot Tip Explant
2021
Girmay Mekonen | Meseret Chimdessa Egigu | Manikandan Muthsuwamy
Banana is a fruit crop which has high demand in Ethiopia, but its production is constrained by lack of disease free planting material with conventional propagation methods. For shoot initiation, shoot tip explants were cultured on MS medium supplemented with 0.5, 1.0, 1.5 and 2.0 mg/L BAP. Similarly, MS medium supplemented with BAP at 1.0, 1.5, 2.0 mg/L in combination with IBA at 0.25 and 0.50 mg/L were used for shoot multiplication. Half- strength MS medium augmented with IBA at 1.0, 2.0, 3.0 and 4.0 mg/l were used for root induction. MS medium without PGRs were used as controls. Finally, hardening of the in vitro derived plantlets was carried out in green house both in the primary and secondary acclimatization stages. Results showed that the highest shoot initiation percent (93.40%), highest mean number of shoots per explant (4.67) and lesser day for shoot induction (11.00) were observed in explant cultured on MS + 1.0 mg/L BAP. With shoot multiplication, highest shooting percent (92.60%), maximum number of shoots (7.67) and highest shoot length (5.27 cm) were recorded on MS + 1.5 mg/L BAP + 0.5 mg/L IBA. The highest rooting percent (93.40%), maximum root number per shoot (7.67) and highest root length (11.00 cm) were found on a half strength MS medium + 2.0 mg/L IBA. The survival rate of plantlets were 96.00% in coco peat substrate in primary acclimatization and 97.92% in forest soil, sand and manure substrates mixed at 3:2:1 ratio in secondary acclimatization. Overall, the result showed that the PGRs type, concentrations and combinations used are effective for mass propagation of banana variety studied in this experiment.

2021
Pelin Talu Özkaya | Seval Dağbağlı
Food packaging has an important role in protecting food against physical, chemical, and biological hazards during storage and distribution and in informing the consumer about the product. The packaging of foods that susceptible to chemical / microbiological spoilage especially such as meat, hence limited storage time, is even more important than other foods. In addition, the tendency of health-conscious consumers to be a part of real-time controls and monitoring food safety has led to the widening of this packaging perception. Hence, there have been innovative studies in recent years, especially aiming real time monitorization of freshness indicators. The focus of these studies is “colour indicators” used in the production of intelligent indicator films and colorimetric sensors within specific matrices to be integrated into packaging materials. The colour indicators change colour in the presence of certain metabolites released in food spoilage, which allows freshness to be determined. Colour substances used for this purpose can be natural or synthetic. Hence, natural pigments such as anthocyanin, curcumin, etc. have been more preferrable since being harmless to the health as well as increasing tendency of consumers to utilization from natural resources. In this review, information about natural colour indicators and studies in which these indicators are used to determine the freshness of meat in real time and visually are given.

2021
Sonali Bhakta | Shonkor Kumar Das
Syzygium aromaticum commonly known as Clove is considered to be the most precious spice among others, which has been continued to be utilized for centuries for different biological and therapeutic purposes. It is a tropical tree which belongs to the Myrtaceae family and natively originated from Indonesia. However, in current times it is found in a few other places of the world including Brazil. Clove is viewed as perhaps the most extravagant source of phenolic mixes, for example, eugenol, eugenol acetic acid derivatives and so on. These mixtures have incredible potential for restorative, organic and other rural applications. In this review we have tried to figure out some of the important medicinal or therapeutic as well as phytobiotic and agricultural utilizations of the products prepared from Clove. We have tried to give an extra emphasis on the application of clove as a product of herbal contraception however for this purpose dose of the extract (either aqueous or ethanolic) of clove plays the vital role in this case. Although for establishing or making clove products commercially available as a safe product for herbal contraception or other medicinal impacts, more studies are required, and it could open a new era in the field of herbal medicine that would be much safer and feasible.
Afficher plus [+] Moins [-]The Effect of Cage System and Stocking Density on Performance, Egg Quality and Microbial Load of Eggshell of Laying Hens
2021
Zeynep Yardım | Mustafa Akşit
This study was carried out to determine the effects of two different cage systems (enriched and conventional) and low and high stocking densities on performance, egg quality and egg shell microorganisms. In study, two different genotypes were used to native (Atak-S) and foreign (Lohmann) hens occurred of 864 hens used. As the cage system, the battery type was used in the conventional system and the enriched cage type was used in the alternative system. The results indicated that genotype and cage system significantly affected egg production and egg mass in the laying period (18-76 weeks). It was determined that Lohmann genotype and conventional cages had significantly higher egg production and egg mass in this period. It was seen that hens consumed significantly higher feed in enriched cages than in conventional cages, and were significantly better feed conversion ratio in low stocking density compared to high stocking density. The effects of genotype and cages system on the quality characteristics of eggs were found to be significant, and it was determined quality characteristics of Lohmann eggs were better (especially eggshell quality. In addition, it was understood that the internal quality of the eggs in the conventional cages and the external quality characteristics of the eggs in the enriched system were positively affected. The total numbers of microorganisms were determined to be higher on shell of eggs from enriched cages than conventional cages. The total numbers of microorganisms were higher in enriched cage eggs compared to conventional cage eggs. However, stocking density was not a significant effect on the microbial load of the eggshell.

2021
Jacob Matovu
The need for studies on the nutritional value of plants depends on their composition. The first generation genetically modified Plants (GMPs) have the same composition as their near-isogenic lines. Therefore, they have the same nutritional value, and most of the animal feeding studies have found no significant differences in the production and health parameters of animals that consumed first-generation GMPs in comparison to non-GMPs. Due to the recent production of transgenic plants with specific nutritional properties (second generation GMPs), their use as feed for animals is viewed with skepticism in very many countries. In this critical review, it is concluded that most of these nutritionally improved plants have not shown adverse effects on the performance of various animals compared to their near-isogenic lines and can therefore be considered in the animal feed industry. However, most of the experiments were conducted on laboratory animals. There is a need to conduct them with animals that are mainly consumed by humans, such as ruminants. There is also a need to feed the whole plant to these animals and not just certain parts of the plant to get a clear picture of its overall safety. In addition, there is a need to determine a suitable long-term nutritional and toxicological approach assessment.

2021
Mehmet Aksoy | Başaran Karademir | İbrahim Hakkı Kadirhanoğulları
Organic Agricultural products are natural food products that are checked and certified by authorized institutions at all stages of cultivation and presented to the consumer. In this study, the knowledge and practices of soil agriculture farmers in Amasya province about Organic Agriculture production were investigated by face-to-face survey method. In the survey, the local producers were asked what Organic Agriculture is in general, their status of producing Organic Agriculture, whether they fulfill the Organic Agriculture requirements for Organic Agriculture production. The obtained data were presented numerically and proportionally. Data were also analyzed with the Decision Tree method using the CART (Classification and Regression Tree) algorithm. According to the findings, although the local farmers declared that they knew what Organic Agriculture was at a high level, it was seen that none of the producers fulfilled the requirements of Organic Agriculture in practice. According to the survey data, while the farmers reported that they received the information about Organic Agriculture from TV-radio and the internet to a large extent (58.5%), a very small percentage (11%) stated that they received training. According to this result, it has been concluded that the local farmers do not have enough information about Organic Agriculture, but the lack of information can be easily eliminated via TV-radio and the internet. As a result, it was concluded that Amasya farmers do not have sufficient information about Organic Agriculture production for now, but if appropriate training is provided, successful Organic Agriculture production output can be achieved.

İsrafil Kocaman | Can Burak Şişman | Hüseyin Cömert Kurç
This research was carried out to investigate the possibilities of removing the heat stress that may occur in Anatolian water buffaloes with a fogging system and to determine the cooling efficiency of the system. In this context, two 24-headed groups were formed among the water buffaloes that were considered to have the same genetic similarities, were born in the same period and have the same lactation number. One group was housed under controlled shelter conditions (Shelter-I), where the ambient temperature can be controlled, and the other group was housed in existing farmer-raising conditions (Shelter-II). The same feed rations were applied to both buffalo groups. The cooling efficiency of the fogging system established in Shelter-I was between 45.6% and 85.7% positive. Temperature-Humidity Index values changed between 19.9 and 23.1 in Shelter-I and 19.5 and 26.4 in Shelter-II according to the maximum average data. According to these values, the level of stress in Shelter-II has reached very serious levels and affected the milk yield of buffaloes negatively. The corrected 305-day lactation milk yields were calculated as 1965.4 kg in Shelter-I and 1757.1 kg in Shelter-II. The differences between all data obtained for Shelter-I and Shelter-II were found statistically significant.

The aim of this study is to determine the effect of four levels of irrigation water and three kinds of fertilizer on components of field-grown eggplant (Solanum melongena) in the years 2017 and 2018. Treatments included four irrigation regimes, which were 100% (I100, control), 80% (I80), 60% (I60), and 40% (I40) of evaporation from Class A pan and three different fertilizers, which were chemical fertilizer (CHF) with 40 kg da-1, organic fertilizer (OF) and developed organic fertilizer (DOF) with 2000 kg da-1. The experiment was designed with a split-plot randomized block with 3 replications. In experimental years, all irrigation treatments were irrigated 12 and 13 times, respectively with a drip irrigation system. Irrigation water amounts applied at I40, I60, I80, I100 in 2017 as 122, 183, 244, 305 mm and in 2018 were 147, 218, 289, 360 mm respectively. Seasonal plant water consumption values are in 2017, 2018 years respectively as follow: I40; 265 mm, 277 mm I60; 326 mm, 342 mm, I80; 386 mm; 382 mm, I100; 447 mm, 423 mm. In both experiment years, the effect of irrigation levels on plant components was statistically significant, the highest value of each component in both seasons was at I100 treatment, it was determined respectively as follow: Plant height PH (67.3 to 89.8 cm), branches number per plant BN (5.1 and 7.0), fruit number per plant FN (5.3 and 7.0), fruit weight FW (190.33 and 198.22 g).

This study was conducted on a total of 776 goats (part of Central highland goat breeds of Ethiopia), 306 from Boset district of Oromia region and 470 were from Minjar Shenkora district of Amhara region. A format developed by using food and agriculture organization discerption list was used for recording of morphological traits, bodyweight and linear body measurements. Both qualitative and quantitative traits were recorded from randomly sampled mature goats and the data were analyzed using SAS software. The goat type in the study area was characterized by a higher proportion of plain coat color patterns (62.5). Ingeneral, the majority (98.4%) of the studied goats were horned and characterized by backward orientation (67%) with a straight shape (49.3%). They presented a concave facial profile (73.8%), slop up toward the rump back profile (66.2%), no wattle (99.6%), no toggle (90.7%), no ruff (85.9%) and no beard (57.3%). The location had a significant effect on body weight and some other linear body measurements. Traits like body length, rump length, horn length, head length, head width and shin circumference were significantly higher in Boset district. In contrast, rump width and cannon bone length were significantly lower. The mean body weight of male goats in Boset and Minjar Shenkora district were 30.5±1.05 kg with a range of 16 to 47 and 27.5±0.56 with a range of 13 to 57, respectively. While for female counterpart mean body weights (kg) were 28.4±0.35 with a range of 17 to 45 for Boset and 27.5±0.33 with a range 15 to 57 for Minjar Shenkora district. Heart girth had the highest correlation with body weight in both sexes and shoulder width in Boset male goats. The wider variation in most quantitative measurement traits would open an opportunity for further improvement, conservation and utilization work.
