The paper tackles the problem of making direct payments in the EU countries more equal. Two sets of indices and their evolution are being presented: payment rates per product and per hectare of eligible area. The need of redistribution of direct payments is being stressed, followed by the discussion on different scenarios of distribution among Member States. The model finally accepted by the EU...
This paper examines the possible impact of climate change on Malaysian rice production. Using the Ricardian Method and farm household data, we have examined the effects on rice producers focusing on sharecropper adaptations and ecological causes. The principle goal of this research paper is to investigate the impact of climate variables such as temperature, rainfall and precipitation on rice pr...
We investigated the sprouting capacity of poplar stumps in ten 8–21-year old stands growing on former farmland in Sweden situated between 55°N and 60°N. Seven of the stands were planted with the clone OP-42 (Populus maximowiczii Henry × Populus trichocarpa Torr. and Gray), one with black cottonwood (Populus trichocarpa Torr. and Gray) and two with unidentified clones. The poplars’ mean age was ...
objective:investigating the microbes and interactions of the beneficial symbiotic relationships between the components of the system ecology in the food chains and life cycles is one of the modern sustainable agriculture topics. in this regard, to evaluate the effects of bacteria and vermicompost on morphological characteristics and yield of soybean an experiment was conducted as split plot in ...
In breeding programs determination of gene effects and general and specific combining ability for screening of test crosses is necessary. In order to estimate the genetic variance components and the general and specific combining ability of sweet corn lines, an experiment was conducted using 8 sweet corn S6 inbred lines (including 4 maternal and 4 paternal lines) by line × tester mating design ...
objective: an experiment was performed in ardabil (2012) to investigate the effects of manure consumption in different amounts on reducing nitrogen fertilizer consumption in potato cv. agria. methods: this research was conducted in factorial design based on randomized completely blocks design in three replication in which two manure factors in three levels (control, 30 and 60 tons/h) and nitro...
Rice is a second important crop in Iran and its cooking and eating quality plays important role for consumers. In order to improve yield and quality, a set of crosses among Amol3 and Sepidrood made with Domsiah Mashhad and Sange-Jo (Amol3 and Sepidrood belong to improved and Domsiah Mashhad and Sange-Jo belong to local varieties). The F1s is back crossed with local varieties as parents for two ...
In a 3-yr study, 135 crossbred steers (330 ± 10 kg) were used in a randomized complete block design to evaluate corn dried distillers grains plus solubles (DDGS) fed to yearling steers as a substitute for forage and N fertilizer and its effect on N use efficiency in yearling steers grazing smooth bromegrass pastures. Steers were initially stocked at 6.8 animal unit months (AUM)/ha on nonfertili...
to investigate the possibility of tank-mix application of two herbicides; nicosulfuron+ rimsulfuron (ultima 4% sc) and bromoxinil+mcpa (bromicide ma 40 % ec) for control of narrow and broadleaf weeds in corn an experiment was carried out in jiroft agricultural research centers during 2010. the experiment was conducted in a rrandomized complete block design with two-factors and four replications...
to investigate the possibility of tank-mix application of two herbicides; cruz (nicosulfuron 4% sc) and bromicide ma (bromoxinil+ mcpa 40 % ec) for control of weeds in corn an experiment was carried out in jiroft and kahnoj agricultural research center during 2009. the experiment was conducted in a factorial experiment based on randomized complete block design with four replications. the first ...
