Household survey data was used to quantify the on-farm PHL for these vegetables at different stages between the crop’s harvest and the sale or consumption. A multi-market model was used to simulate the effect of eliminating vegetable PHL on the total value of vegetable supply and international trade of vegetables at the national level. Results suggest that on average 30% of vegetable production is lost on-farm and is therefore unavailable for sale or consumption. Eliminating these losses could increase the total value of vegetable supply by 45% (US $72 million) per year and reduce vegetable imports by 22% (127,000 tons) per year. Moreover, our results indicate that both private costs to farmers and public costs to the government related to such PHL reductions would need due consideration when prioritizing between investments in the agricultural sector and beyond.","PeriodicalId":349966,"journal":{"name":"AgriSciRN: Agricultural Plant Products (Topic)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115266335","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}

A green house experiment was conducted at Jimma University College of Agriculture and Veterinary Medicine during 2014/15 cropping season to investigate the effects different sowing depth on germination and growth performance of maize. The experiment was consisted of five level of sowing depth (2cm, 4cm, 6cm, 8cm and 10cm) in randomized complete design with three replications. The data were collected based on seed germination which determined by germination percentage and germination date with their growth performance. The results showed that sowing at depth of 6cm produced the tallest plant, highest number of leaves per plant, leaf length, leaf fresh weight and dry weight. The 10cm depth showed late in germination date and has poor performance as compared to other sowing depth when looked over the result. However, the results of the experiment were only growth parameters and did not include yield. So, similar research is needed to be conducted until final yielding of maize for better recommendation.","PeriodicalId":349966,"journal":{"name":"AgriSciRN: Agricultural Plant Products (Topic)","volume":"184 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":"116309648","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}
