The present study was initiated with the investigate the effect of agroforestry and seasonality (during two successive years) on five range species using moringa tree in the model. The study utilized an enclosure located in a peri-urban area in west Omdurman within Khartoum state. 960 meters square was divided into five blocks were allocated for the plantation with five range species; one used as a control and the other for agroforestry experimentation. Each block was divided into 4 plots and subplots as replicates where range species were randomly selected for plantation trials. Measured parameters included days to germination, flowering and seed setting as well as productivity dry matter yields (ton/hectare). The nutritive value was analyzed for preand post-flowering physiological status. Soil samplings were done before and after plantation for the study of soil minerals and pH. The results showed that agroforestry showed significant (P ≤ 0.001) positive effects for all range species. During the year 2014, the highest yield was obtained by Dactyloctnium aegyptium (90 Ton), followed by Farsetia longisiliqua Decne (21Ton), then Lasiurus scindicus Henrard (14Ton), Clitoria ternatae (7 Ton) and finally Alysicerpusmonilifer (2.1 Ton). During the year 2015, the highest yield was obtained by Lasiurus scindicus Henrard (2489 Ton)followed by Clitoria ternatae (289 Ton), then Dactyloctnium aegyptium (92Ton)then Alysicerpus monilifer (91Ton) and Farsetia longisiliqua Decne(90 Ton). The effect of year on control and agroforestry treatment, was significant (P ≤ 0.001) with better yield for year 2015. Nearly all range species showed the same days for germination (~ 8 days), while Moringa showed longer days (21days). For the nutritive value of the plants, crude protein (CP) contents increased in postcompared with pre-flowering. CP increased for Moringa (P ≤ 0.01), Dactyloctnium aegyptium and Clitoria ternatae (P ≤ 0.05). Dry matter (DM) increased significantly (P ≤ 0.01) only in Moringa, whereas, both Dactyloctnium aegyptium and Clitoria ternatae showed significant (P ≤ 0.05) decrease in DM. Ether extract content decreased with post-flowering for all plant species, but significant differences were only observed with Moringa (P ≤ 0.01), Lasiurus scindicus Henrard and Clitoria ternatae (P ≤ 0.05). Significant (P ≤ 0.05) decreases in ash contents were observed for all plant species with post-flowering except for Moringa which showed significant (P ≤ 0.01) increase. Anaylsised soil showed significant improvement after plantation as compared before plantation, however, soil salinity and phosphours was significantly (P ≤ 0.01) reduced due to plantation. It could be concluded that the use of agroforestry in range could greatly improve range condition.

This study was conducted under both open field and glasshouse conditions at Ambo University during the main cropping season of 2013-2014 using six different improved tomato varieties ‘Miya’, ‘Chali’, ‘Fetan’, ‘Melka-selsha’, ‘Melka shola’, ‘Cochoro’ and ‘Local round’ which were evaluated for their general performance,and resistance to insect pests The Randomized Complete Block Design (RCBD) was adopted with three replications. The result of the study revealed significant (P<0.001) differences for all parameters measured.. The maximum number of primary branches per plant was recorded in the varieties, ‘Chali’ (5.67), Miya’ (5.33), and ‘Melka shola’ (5.0) and the minimum number of primary branches per plant was recorded in variety, ‘Fetan’ (3.73). The maximum number of fruits per plant was recorded in ‘Melka shola’ (75.33) followed by ‘Melka-Selsa’ (64.33), while ‘Fetan’ and ‘Mira-1’variety hadthe minimum fruit numbers of (15.0and 15.67), respectively. The maximum marketable and non-marketable fruit yield per plant was observed in ‘Chali’ (2.0 kg/plant) and the minimum was in ‘Melka selsa’ (0.9 kg/plant) under open field. But in glasshouse, the maximum marketable yield (2.06 kg/plant) and the minimum (0.31kg/plant) was recorded in ‘Melka shola’ and ‘Chali’. Regarding insect pests and diseases, the varieties were significantly (P<0.001) different. The highest insect damage by fruit borer was in ‘Miya’ (4.33% / plant) and the minimum was observed in ‘Melka shola’ (1.67% / plant) under open field but in glass house condition, the maximum and the minimum was scored in ‘Melka selsa’(4.67% / plant) and in ‘Fetan’(1.0% / plant). Considering the total fruit yield, the maximum yield was recorded in ‘Chali’ (3.24 kg/plant) and the minimum was in ‘Fetan’ (1.13% / plant) under open field but in glasshouse condition, the maximum fruit yield was recorded in ‘Melka shola’ (4.04 kg/plant) and the minimum in ’Cochoro’ (1.61 kg / plant). This study was concluded that the tomato varieties, ‘Melka shola’ and ‘Fetan’ showed relatively good and poor performance in all parameters, respectively. Growing conditions within a glasshouse could be significantly different from growing conditions in open field production.

Coffee has a substantial source of income for the Ethiopian growers as well as world market contributing (Worku and Astatkie, 2010). The coffee market fluctuation in the international trade has been affected by the low production of coffee and its quality (ITC, 2010). South-West Ethiopia is well known for tropical humid and lowland crop cultivation including coffee. The area receives an annual average of 1500mm precipitation. However, the presence of erratic rainfall has created moisture stress during the critical period of coffee cultivation and the yield has been severely reduced.

The genus Brassica of Brassicaceae family as a whole is believed to have originated around the Mediterranean, Eastern Afghanistan and the adjoining portion of Pakistan and North-Eastern Africa (Hemingway, 1976). The genus includes six economically important species, namely, Brassica rapa, B. oleracea, B. nigra, B. juncea, B. napus, and B. carinata (Doweny and Robbelen, 1989). Ethiopian mustard is believed to be originated in the highlands of the Ethiopian plateau and the adjoining portion of East Africa and the Mediterranean coast (Gomez-Campo and Prakash, 1999).It evolved as a natural cross between B. nigra (BB) (n=8) and B. oleracea (CC) (n=9) and underwent further chromosomal doubling (2n=34; UN, 1935). It is partially amphidiploids.

Nepal is an agricultural country where 68% of people are dependent upon agriculture for their livelihood (USAID, 2019). Total Gross Domestic Product (GDP) contribution of Agriculture sector in Nepal is 33.7%, out of which poultry sector contributes about 3.5% of GDP (CBS, 2012). Poultry are domesticated avian species that can be raised for eggs and meat. The term “poultry” covers a wide range of birds, from indigenous and commercial breeds of chickens to muscovy ducks, mallard ducks, turkeys, guinea fowl, geese, quail, pigeons, ostriches and pheasants (FAO, 2019).

The experiment was executed to analyses seed yield and related traits stability parameters for ten genotypes of linseed at Holeta, Kulumsa, Bekoji and Asassa representative areas of central highlands of Ethiopia. The experiment was carried out in a Randomized complete block design. Stability parameters for ten genotypes of linseeds were evaluated and assessed using three different stability methods. The investigation included six characters ( seed yield per plot, oil content, oil yield, date of flowering, date of maturity and plant height). Results revealed significant genotype × environment interactions were detected for seed yield, oil content, date of flowering and plant height studied traits and the response to environmental changes of each genotype differed as indicated by M.S. pooled deviation and heterogeneity items. Wider ranges of regression coefficient values were observed from the studied stability methods suggesting possibility of selection for specific genotypes patterns. Two genotypes PGRC/E10306 X Chilalo Y/3 and Omega X CI-1525/Y/44 were most stable for studied characters in the four central highlands of Ethiopian environments.

A study involving 35 Friesian x Indigenous (CROSSBRED) and 35 Indigenous (INDIGEN) nonlactating multiparous cows was conducted in Mazabukato investigate the effect of Prostaglandin F2α (PGF2α) on estrus synchronization. On day 0, the cows were intramuscularly injected with 2 ml of PGF2αand observed for estrus. On day 11, the injection was repeated in those cows that did not respond to the first injection. The Estrus Response (%) and the Response Time (hours) were statistically compared between the two groups of cows. Twelve (34%) CROSSBRED and five (14%) INDIGEN cows came into estrus following administration of PGF2α. While the Estrus Response was low in both groups of cows, the number of responsive CROSSBRED cows was numerically higher than that of INDIGEN cows. The Response Time was, however, similar (P>0.05) in both groups of cows. It is concluded that estrus synchronization with PGF2αhad more effect in CROSSBRED cows than in INDIGEN cows. For practical purposes, however, the apparent greater effect of PGF2α in CROSSBRED cows was not significant to warrant recommendation. This technique is therefore not recommended for smallholder dairy farmers under the current management levels. Further research on how to improve the effectiveness of estrus synchronization is recommended.

For practical purposes, however, the apparent greater effect of PGF2α in CROSSBRED cows was not significant to warrant recommendation. This technique is therefore not recommended for smallholder dairy farmers under the current management levels. Further research on how to improve the effectiveness of estrus synchronization is recommended.","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128416071","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}

Genetic diversity is a pre request for successful breeding program. The study was conducted at Adet in 2018/19 under field condition in simple lattice design with three replication. The aim of the study was to identify genetically divergent potato genotypes having desired traits for further potato breeding activity. A total of 36 potato genotypes were evaluated for 18 quantitative traits in simple lattice design. The analysis of variance revealed that highly significant (p < 0.001) difference among the tested potato genotypes for all quantitative traits except stem number per hill. The studied 36 potato genotypes were grouped in to five distinct clusters. Cluster V was the largest cluster which consisted of eleven genotypes (30.56%) and cluster III comprise three genotypes (8.33%). Clusters I and IV having divergence distance can be used as a parent for further breeding or crossing. The highest and lowest intra cluster distance was observed in cluster III (4.97) and V (2.37) respectively. A total of six principal component with an Eigen value >1 accounted for 78.22% of the total variation in the studied potato genotypes.

There are two types of phospholipids present in vegetable oils namely the hydratable and nonhydratable. Simple water degumming will not remove non-hydratable gums. High phosphatide containing oil like soybean oil (700ppm) water degumming alone is not satisfactorily to reduce the phosphatide content below 10ppm. Therefore enzymatic process is used together with water degumming. Degumming is an important step in oil refining process and removes phosphatide (gum) along with some other unwanted minor compounds without destroying the beneficial ones.
