The Corona Virus is the pandemic all over the world. This viral infection attacked all over the world like as disaster of viral infection which causes morbidity and mortality in different regions of world like Asia, Europe, and Africa etc. The different countries control the spread and complications of covid-19 like Acute Respiratory Distress Syndrome in well manner. In second wave there was again out break of covid-19 some regions of world. Here we discuss the causes of reoccurrence and their preventive measurements from our break effects of Covid-19.

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.

This study was conducted to examine the soil fertility of the Büyük Menderes Basin, where wheat is widely cultivated. Soil samples were taken from 50 different points at a depth of 0-30 cm and various physical and chemical properties and amounts of nutrient elements were determined. With regard to the results of the study, the soils were generally sandy-clay-loam in texture, with slightly alkaline reaction, limy, rich in organic matter and showed no risk of salinity. The examined soils were found to be insufficient as 34% for total N, 14% for available K, 26% Mg, 10% Fe, 94% Zn and 98% Mn contents while all of the soils were determined as sufficient in terms of available P, Cu and Ca contents. When relationships between nutrient elements and soil physical-chemical properties were examined, negative correlations were found between soil pH and EC, organic matter, total N, available K, Zn; lime contents and available Mg, Fe, Cu; clay and available K and Mn contents. The positive correlations were found between EC and available K, Ca and Zn; organic matter % and total N, available K, Cu, Zn and Mn; sand % and available Mn; clay % and available Fe contents. Investigation of relationships between plant nutrients demonstrated that, there were positive correlations between total N and available K, Cu, Zn, Mn; available P and Zn; available K and Cu, Zn, Mn; available Ca and Fe; available Mg and Fe, Cu; available Fe and Cu, Mn; available Cu and Mn contents. The results of the study showed that attention should be paid to fertilization programs to fertilization with Zn and Mn, which were found to be insufficient in the greater part of the basin’s soils, and also to nitrogen deficiency is observed, as this directly affects the protein content of wheat.

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.

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.

Bu çalışma, Tokat/Erbaa ve Tokat/Kazova lokasyonlarında tarla koşullarında 2017 yılında topraktan artan dozlarda (0, 3, 6 ve 9 kg da-1) MgSO4 uygulamalarının Xanthi 81 tütün çeşidinin yaprak verimi, kalitesi ile yaprağın bazı kimyasal (Mg, S, N, K, P, nikotin, şeker, klorogenik ve rutin konsantrasyonu) içeriklerine etkisi araştırılmıştır. Araştırma tesadüf blokları deneme desenine göre üç tekerrürlü olarak kurulmuş olup, hasat olgunluğuna gelen yapraklar üç elde hasat edilmiştir. Elde edilen sonuçlara göre, artan dozlarda MgSO4 uygulaması ile Erbaa ve Kazova lokasyonlarında yetiştirilen tütün çeşidinin yaprak veriminde artışlar meydana gelmiştir. Yaprak veriminde ortaya çıkan artış en fazla MgSO4’ın 6 kg da-1 dozunda görülmüş ve bu artış Erbaa lokasyonunda %22, Kazova lokasyonunda ise %6,4 düzeyinde olmuştur. Artan MgSO4 uygulamaları ile yaprak Mg ve S konsantrasyonlarında istatiksel olarak önemli artışlara neden olduğu, en fazla artışın yaprak veriminde olduğu gibi MgSO4’ın 6 kg da-1 dozunda olduğu görülmüştür. Tütün için çok önemli bir alkaloid bileşeni olan nikotin konsantrasyonu MgSO4 uygulaması ile her iki lokasyonda da azalmıştır. Sonuçlar, artan dozlarda MgSO4 uygulamalarının tütün yaprağının veriminde artışa neden olduğu, yaprak Mg ve S konsantrasyonlarında artışa, nikotin konsantrasyonlarında ise azalmaya neden olduğu ortaya çıkmıştır.

Two experiments were conducted in the Savelugu-Nanton Municipality of the Northern Region of Ghana in 2012 and 2013 to assess the effect of N fertilizer on growth, N remobilization and grain yield of three local varieties of soybean (Glycine max [L] Merill). The experiments were a 3 x 4 factorial laid in Randomized Complete Block Design (RCBD) with four replications. Factor A was soybean varieties (Jenguma, Quarshie, Ahotor); Factor B was 0, 15, 30 and 45 kg N ha-1. The experimental fields were planted manually on the flat by drilling and later thinned to 2 plants hill-1 at 0.50 m × 0.10 m with a population of about 400 000 plants ha-1. Growth and yield parameters measured were plant height, nodule number plant-1, nodule dry weight plant-1, percent nodule effectiveness, number of pods plant-1, number of seeds pod-1, 100 seed weight, harvest index and grain yield. The results showed that the control recorded lower figures in all growth parameters. Nitrogen remobilization was also observed in all plots, which indicate that soybean needs greater levels of N during grain filling. Again, N remobilization and soybean yield were highest in the 45 kg N ha-1 treatment compared to the other treatments. However, considering the overall yields, farmers in the study area should be advised to adopt starter N fertilization of soybean for higher yields as the soils are highly degraded in soil fertility.

This study was conducted to determine the effect of production system, slaughter age, and gender on the nutrient composition, fatty acids profile, and index values of breast and thigh meat in Alectoris chukar partridges. Partridges were slaughtered at 14, 16, and 18 weeks of age and skinless breast and thigh meat of male and female were used in the study (a total of 96 samples in 2 replicates). The production system affected only the crude fat level of the thigh meat in terms of nutrient composition and it was found higher in the intensive system compared to the free-range system. Age and gender did not significantly affect the composition of breast and thigh meat. In terms of fatty acid profile, erucic acid (C22:1n9) level in breast meat was higher in intensive system, while it was higher in thigh meat in free-range. While the percentage of docosahexaenoic acid (C22:6n3) increased with age in breast meat, it decreased in thigh meat with age. While eicosenoic acid (C20:1) percentage was higher in breast meat of male birds compared to females, only stearic acid (C18:0) was found to be higher in thigh meat. Saturated fatty acids (SFA), linolenic acid (n3), thrombogenic index (TI) and atherogenic index (AI) values were higher in thigh meat produced in free-range system, while polyunsaturated fatty acids (PUFA), total unsaturated fatty acids (UFA), linoleic acid (n6) and hypocholesterolaemic / hypercholesterolaemic ratio (h/H) were significantly higher in intensive system. While SFA and TI levels in thigh meat decreased with age, monounsaturated fatty acids (MUFA), UFA and oleic acid (n9) percentages increased. MUFA / SFA in thigh meat of females was higher than males, other indexes were found insignificant. The results shows that partridges had desirable fatty acid composition. Especially, the increase in MUFA and UFA values with age in thigh meat compared to breast indicates that thigh meat is enriched in terms of unsaturated fatty acids. However, the higher SFA and AI values obtained in the free-range system could be considered a negative outcome for alternative production systems that prioritize bird welfare and consumer demands.
