However, in Ethiopia, the yield per unit area of potato is very low compared to those of other countries. There are many factors that reduce the yield of the crop among which the diseases like late blight and insect like tuber moth which play an important role in reduction of the yield. Hence, the objective of this review is to review the importance of these late blight and tuber moth of potato and their management in Ethiopia. In Ethiopia, late blight is occurs throughout the major potato production areas and researches have made estimates of losses ranging from 6.5 to 61.7%, depending on level of susceptibility of the varieties. Different types of management options like cultural, Fungicide Use, biological and Resistant Cultivars are the major management practices which can help in reducing late blight effect. However, because of its new strain development, there is no single effective management strategy of this disease. Therefore adopting integrated disease management approach is the most effective, environmentally safe and low costly to the users. In addition to late blight, potato tuber moth can also cause significant yield loss to potato. Potato tuber moth is the most important constraints of potato production in Ethiopia and it causes up to 42% yield loss in storage. Using different integrated pest management approaches including appropriate cultural practices, using pheromone traps, using biological control, host plant resistant, using botanicals and appropriate rate and time of chemical applications are used for reducing the damage of potato tuber moth.","PeriodicalId":7255,"journal":{"name":"Advances in Crop Science and Technology","volume":"154 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88198833","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 present study therefore, has been designed to investigate the influence of variety, intra-row spacing and their possible interaction on growth and yield of onion. The study was conducted under irrigation during the year 2016/2017 at Jimma University College of Agriculture and Veterinary Medicine, on experimental site of horticultural crops. Four onion varieties (Adama Red, Nafis, Melkam and Nasik Red) and three intra-row spacing (7,10 and 13 cm) with inter-row spacing of 20 cm. The experiment was designed in RCBD with three replications. The results of the study showed that both variety and intra-row spacing had a significant effect (P˂0.05) on all parameters, except for the leaf diameter which was only affected by intra-row spacing. Leaf number per plant was significantly affected by interaction of variety and intra-row spacing. The highest leaf number (13.9) obtained from variety Nafis with intra-row spacing of 13 cm. In general, leaf number per plant, leaf length, plant height and leaf diameter were higher at wider intra-row spacing (13 cm). Nafis variety was superior in terms of leaf number per plant (13.9), bulb diameter (5.67 cm), average bulb weight (74.50 g), marketable yield (36.26 t ha-1) and total bulb yield (36.28 t ha-1). Onion plant grown at closer intra-row spacing (7 cm) showed very promising result for average bulb weight, marketable yield and total tuber yield. Moreover, the closest intra-row spacing (7 cm) gave higher marketable and total bulb yield than the wider intra-row spacing. Thus, growers in the study area can be benefited from closer intra-row spacing, however, it is paramount important to test the feasibility of the other closest intra-row spacing e.g., 6 cm and 4 cm.","PeriodicalId":7255,"journal":{"name":"Advances in Crop Science and Technology","volume":"5 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79999158","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}

Moreover, increasing temperatures, reduced irrigation-water availability, flooding, and salinity will be the major limiting factors in sustaining and increasing vegetable productivity. Under changing climatic situations crop failures, shortage of yields, reduction in quality and increasing pest and disease problems are common and they render the vegetable production unprofitable. As many physiological processes and enzymatic activities are temperature dependent, they are going to be largely effected. Drought and salinity are the two important consequences of increase in temperature worsening vegetable production. These effects of climate change also influence the pest and disease occurrences, host-pathogen interactions, distribution and ecology of insects, time of appearance, migration to new places and their overwintering capacity, there by becoming major setback to vegetable cultivation. To mitigate the adverse impact of climatic change on productivity and quality of vegetable crops there is need to develop sound adaptation strategies. The emphasis should be on development of production systems for improved water use efficiency adoptable to the hot and dry condition. The crop management practices like mulching with crop residues and plastic mulches help in conserving soil moisture. Excessive soil moisture due to heavy rain becomes major problem that can be overcome by growing crops on raised beds. Development of genotypes tolerant to high temperature, moisture stress, salinity and climate proofing through conventional, non-conventional, breeding techniques, genomics and biotechnology etc. are essentially required to meet these challenges. Therefore, the objective of this paper is to review the effects of climate change on vegetable production and its management practices.","PeriodicalId":7255,"journal":{"name":"Advances in Crop Science and Technology","volume":"98 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78530356","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}
