For this to succeed, we need to know what the most appropriate and useful information is, how best to transfer it and how to overcome barriers to its transfer. This study fills the gap in our understanding through focus on the small island nation of Timor-Leste, where improving agricultural productivity and overall food security is a key challenge. This is compounded by a rapidly expanding population, poor agricultural conditions, a reliance on small-scale subsistence farming and the impacts of climate change such as increased temperature and altered rainfall patterns. Drawing from six focus groups (n = 29 farmers) in four districts, coupled with stakeholder interviews (n = 6), this study identified seasonal outlooks to be most desired by farmers, followed by shorter-term (daily, weekly) forecasts. Radio was considered as the most effective method to reach smallholder and subsistence farmers, although face-to-face communication was also highly valued by farmers. Language difficulties and low literacy levels, economic circumstances, some general misconceptions about climate change, and limited trust in community leaders were the main barriers to information transfer. If climate information is to be provided to farmers, it is essential that quality and accurate information is delivered, and those involved in liaising and communicating directly with farmers have the education and training to understand and accurately pass on this information.","PeriodicalId":15809,"journal":{"name":"Journal of Food Agriculture & Environment","volume":"121 1","pages":"64-72"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84707591","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}

Large and medium seed size of ten maize hybrids harvested in two subsequent years were tested by standard germination test (SG), cold test (CT) and electrical conductivity test (EC), as well as by germination test after EC evaluation. The effects of seed size, seed age, hybrid and their interactions were strongly expressed in the majority of analysed seed and seedling vigour parameters. Mean seed germinability evaluated after EC test was 91.7%, which was slightly lower than mean SG value (%), implying no significant imbibitional damage especially in hybrids with high seed vigour. EC value under 10 µS cm -1 g -1 was obtained with seed showing high germination and seedling vigour for both SG and CT. EC values higher than 12 µS cm -1 g -1 were recorded with seed samples showing low germinability after EC test, which germinated less than 50% in CT conditions as well. EC test value showed strong negative correlations with the most of the maize seed and seedling vigour parameters in the applied germination tests, such as germinability, germination rate, root and coleoptile length and seedling mass. The presented results may help in the standardization of this very applicable test for maize seed, and its adoption as a routine vigour test in maize seed production and quality control is suggested.","PeriodicalId":15809,"journal":{"name":"Journal of Food Agriculture & Environment","volume":"9 1","pages":"140-145"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88350793","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}

Therefore, understanding of the impact of crop rotation on soil physical processes and soil compaction is important to develop systems of sustainable management of soil and water resources in intensive agriculture. The objective of this research was to determine the effects of selected rotation systems on soil characteristics and penetration resistance of the Harran soil series, currently under dryland agriculture. Field experiments were conducted using a randomized complete block design with eighteen crop rotations and three replications between 1999 and 2000 under field conditions. The results indicated that the penetration resistance, bulk density, and porosity values of soil under different crop rotation management showed statistically significant differences. Soil bulk density and penetration resistance decreased from 1.41 to 1.32 g cm -3 and from 2700 to 1600 kPa, respectively, but porosity increased from 47.7% to 51.1% following crop rotation. Wheat + soy/lentil + corn was the most available crop rotation treatment for Harran Plain.","PeriodicalId":15809,"journal":{"name":"Journal of Food Agriculture & Environment","volume":"12 1","pages":"1021-1024"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84304569","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 damage caused by weeds in maize crop is mostly of 30-70%, and when the infestation is strong the culture can be fully compromised. Our research highlight takes place in Transylvania, and focuses on the influence of Echinochloa crus-galli species (L.) Pal. Beauv. and other weeds on corn production, according to the degree of infestation. The research was conducted at the University of Agricultural Sciences and Veterinary Medicine, Cluj-Napoca, Romania. The research was done on two agrofunds: unfertilized and mineral fertilized with NPK 100 kg s.a./ha. The unfertilized maize crop has been made in four variants with different degrees of infestation of Echinochloa crus-galli, from about 40 to 100 plants/m 2 . Four herbicides (isoxaflutol 750 g/l; acetoclor 860 g/l; dimetenamid 900 g/l; bentazon 320 g/l + dicamba 90 g/l) were used for weed control in fertilized plots . Weed biomass and corn plant and grain production were measured in the ripening stage. Corn invaded by weeds grew weakly and had a yellowish green color; in unfertilized corn plots a stratified weed population developed: Echinochloa crus-galli dominated in the upper layer, Setaria glauca (L.) Beauv. developed in the middle and a number of dicotyledonous species in the lower layer. In fertilized variant, the competition between weeds and maize on one hand and between monocotyledonous and dicotyledonous species on the other hand was more balanced, the biomass of dicotyledonous species ranged from 1700 kg/ha in unfertilized plots to 4100 kg/ha in mineral fertilized plots. The amount of weeds, obviously influenced production levels of maize grain and green mass. Production losses in terms of green mass per hectare can be considered equal to the weight of green weeds. At a density of 104 plants/m 2 of Echinochloa crus-galli with green mass of 18,052 kg/ha corn crop was fully compromised.","PeriodicalId":15809,"journal":{"name":"Journal of Food Agriculture & Environment","volume":"31 1","pages":"760-763"},"PeriodicalIF":0.0,"publicationDate":"2012-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74070149","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}
