Therefore, a field experiment was conducted at Maitsebri Research Station of Shire-Maitsebri Agricultural Research Center (SMARC) to study the effect of inorganic NP fertilizers and vermicompost on growth, seed yield and yield components of red onion (Allium cepa L.) variety during 2016/17 dry season under irrigation. The treatments consisted of five NP fertilizer rates {0, 25, 50, 75 and 100% of recommended NP rates (69 kg N and 92 kg P2O5 ha-1)} and four rates of vermicompost (0, 2.5, 5.0, 7.5 t ha-1). The experiment was laid out in a factorial arrangement using randomized complete block design (RCBD) with three replications. Results of the analysis revealed that the interaction effects on inorganic NP fertilizer and vermicompost significantly (P<0.05) affected plant height. Days to bolting, days to 50% flowering, flower stalk diameter and days to maturity were significantly (P<0.05) affected by the main effect of NP fertilizer rates and vermicompost. Similarly, numbers of umbels per plant, umbel diameter, number of seeds per umbel and seed weight per umbel were significantly affected by the main effect of NP fertilizer rates and vermicompost. The highest seed yield per hectare (1462.5 kg ha-1) was obtained from the plants grown at 75% of RDF with vermicompost at 2.5 t ha-1 which was about 263% higher than seed yield from unfertilized control plot. It can, thus, be concluded that the combined application of 75% of RDF with vermicompost at 2.5 t ha-1can improve growth, seed yield and yield components of Bombay red onion variety in the study area. \u0000 \u0000 Key words: Growth, onion, NP fertilizers, parameters, seed yield, vermicompost.","PeriodicalId":267383,"journal":{"name":"Journal of Horticulture and Forestry","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126803299","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}

The analyzed data results showed that the main effects of spacing and variety and the interaction effect significantly affected growth and yield parameters of the crop. The maximum marketable tuber yield at Haramaya (24.7 t ha-1) and Hirna (27.99 t ha-1) was recorded in response to seed tuber spacing of 60 cm × 30 cm whereas the maximum total tuber yield at Haramaya (34.29 t ha-1) and Hirna (42.07 t ha-1) was obtained from seed tuber spacing of 45 cm × 20 cm.

In-situ rainwater harvesting has positive impact on seedling survivals at degraded rangelands. A quadrant of 10 m × 10 m of five times replication at three slope classes under area enclosure was used. Both survived seedlings and soil physical parameters were collected from three soil depth profiles (0-10, 10-20 and 20-30 cm) and then analyzed. Of the transplanted seedling to the area enclosure with pits (66.53, 46.13, and 25.66%), half-moon (66.53, 41.80, and 20.40%), and soil bund embankment (55.46, 42.60, and 28.80%) were survived at bottom, middle and upper slope classes respectively. The interaction of seedling survival in both planting methods were not significantly different at P>0.05, particularly, in half-moon and pits except soil bund embankment. Because, tree seedling rose at nursery site transplanted to the embankment of structures, that is, on the dig out soils. The conserved moisture is far from seedling roots as a result needs long roots to absorb but weak and short rooting system. Pits and half-moon showed good performance than soil embankments at bottom parts. This explains that almost all in-situ structures play a crucial role at flat land rather than middle and upper parts but highest bulk density achieved for the upper parts, which might be due to risks of soil erosion and only left with very compacted cobles. Therefore, slope gradient have implication on in-situ rainwater harvesting devices efficiencies in conserving moisture for tree seedling survival so as to establish good forest stands. \u0000 \u0000 Key words: Growth, in-situ rainwater harvesting, moisture stress, seedlings, survival.","PeriodicalId":267383,"journal":{"name":"Journal of Horticulture and Forestry","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117249370","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}

Understanding the possible influence of climate conditions on fruit production is a basis for better exploitation planning and sustainable management of the species. This study aims to assess the fruit production of X. americana according to tree size across a climatic gradient. The mean total number of fruits, the mean weight of fruits and the total weight of fruits per tree were calculated based on a sample of 450 trees distributed in five stem diameter classes and three climatic zones. Stem diameter, total height and crown volume were measured for each sampled tree. The global fruit production ranged from 200.37 ± 32.65 to 1027.20 ± 267.72 fruits/tree according to tree size. Trees with larger crown volume produced more fruits with higher total weight than those with smaller crown. The climatic zone significantly affected fruit production (p < 0.0001). The highest fruit weight per tree was recorded in the south-Sudanian phytogeographic zone, with a mean value of 1.49 ± 0.26 kg while the lowest value was observed in the sub-Sahel zone, with 0.67 ± 0.11 kg.

Production of the crop is confronted with a number of problems and the total production and productivity in the country is low. Among many contributing factors, lack of improved varieties and garlic rust are the major ones. In view of this, an experiment was carried out to screen garlic germplasm for yield and diseases tolerance at Debre Markos University College of Agriculture and Natural Resource research field during 2013/14-2016/2017. The experiment was arranged in randomized complete block design with three replications. The result of the study showed high heritability together with high and medium genetic advance for days to physiological maturity, bulb weight, clove number, clove weight and total bulb yield between germplasms and significant variation among the germplasms tested with regard to plant height (cm), leaf length, (cm), maturity date, leaf number, bulb weight (g), clove number, clove weight (g), bulb diameter (cm) and total bulb yield (kg/ha). Different germplasms resulted in better performance with respect to recorded parameters. Germplasms 5 and 18 were found to be superior followed by germplasms 13 and 38. In addition, they recorded maximum plant height, leaf length, bulb weight, clove weight, bulb diameter, total yield, shorter maturity date and moderately susceptibility to rust. The result generally indicated that germplasms G5 (7640 kg), G18 (6929 kg), G38 (4626 kg) and G13 (4601 kg) are promising germplasm in the study area.
