In order to assess the effect of different levels of nitrogen and plant density on Performance and yield components in winter rapeseed (figure Hyola401) experiment in 1388, form band split plot, a the mold a randomized complete block design with four replications, in the city of Sari, was performed. Treatments were included plant density at three levels including 80, 100 and 120 plants per square meter, and nitrogen in four levels, including zero, 5/34, 69, and 5/103 Kg per hectare ,as urea, respectively. Results showed that different levels of plant density had significant effect on number of pods per plant, grain weight, grain yield and harvest index, whereas the number of seeds per pod, biological yield and grain yield influenced by this treatment, were not. Different levels of nitrogen fertilizer, a significant effect on all characteristics, except harvest index found. In this experiment, it was observed that increasing nitrogen levels, effects on all characteristics found. The maximum grain yield, the density of 120 plants per square meter, and maximum application of nitrogen (5/103 kg per hectare), with an average of 4012 kg per hectare, respectively.
为评价不同氮肥水平和密度对冬油菜籽生产性能及产量构成因素的影响(图Hyola401)，采用4个重复的随机完全区组设计，于1988年在沙里市进行了带分割试验。施氮水平分别为0、5/34、69和5/103 Kg /公顷，施氮水平分别为80、100和120株/ m2。结果表明，不同密度处理对单株荚果数、粒重、籽粒产量和收获指数有显著影响，而对单株荚果数、生物产量和籽粒产量无显著影响。不同水平的氮肥对除收获指数外的所有性状均有显著影响。在本实验中，我们观察到增加氮素水平，对所有特性都有影响。籽粒最高产量、密度120株/ m2、最大施氮量(5/103 kg /公顷)平均为4012 kg /公顷。

To study the potential uptake and accumulati on of some essential elements and cadmi um, a field experi ment was conducted using three plants (sunflower, turni p, and forage corn in a randomized complete bl ock design (RCBD) with three replicati ons in a soil classified as Typic Haplog ypsids under wastewater irrigation. The experi ment site was selected i n the farmfiel ds located i n Varamin region in southern Tehran, Iran (2005). The results showed that maximum concentrati ons of nitrogen, phosphorus, zinc, copper, and cadmi um in sunflower were 6.05% , 1.27%, 97.27, 22.84 and 0.54 mgkg -1 respecti vel y. The highest accumulati on of nitrogen, phosphorus, zinc, and copper occurred in grain and cadmium in sunfl ower leaves. The maxi mum concentration of potassium and nitrate occurred in turni p leaves, while the maxi mum concentrations of iron and mang anese were recorded in the root and leaves of forage corn, res pecti vel y.

Participatory variety selection was conducted at Marwoled Kebele, Womberma Woreda, to select superior bread wheat varieties on farmers’ fields with their participations. Bread wheat variety called Kubsa (HAR1685) is the sole variety grown by farmers. Twelve alternative bread wheat varieties were evaluated under rainfed conditions using a randomized complete block design with three replications as grandmother trial and three farmers’ fields with one replication each as mother trial. In both trials, highly significant differences among the genotypes were observed in terms of plant height, spikelets per spike, hectoliter weight, thousand grain weights, leaf rust, yellow rust and days to maturity. HAR3730 (5.4 t ha-1), ETBW5518 (5.3 t ha-1), Plcafeor (4.8 t ha-1), ETBW5521 (4.7 t ha-1), ETBW5520 (4.4 t ha-1) and HAR1685 (4 t ha-1) were highest yielding over the check variety Kubsa (HAR1685) and selected by farmers and researcher. Developed participatory bread wheat varietal selections have solved many constraints related to farmers’ participations, set parameters, select superior varieties, evaluating the performance of better varieties, and identify better varieties and accelerating the dissemination of farmers’ selected varieties at Marwoled Kebele. Therefore, promotion of higher yielding selected cultivars is necessary at Marwoled Kebele to diversify wheat varieties to cope up with evolving disease pathogens and epidemic occurring in wheat system in the region. Key words: Participatory selection, bread wheat, varietal selection.
在Marwoled Kebele, Womberma Woreda进行参与式品种选育，在农民的参与下选择优质面包小麦品种。面包小麦品种Kubsa (HAR1685)是农民种植的唯一品种。采用随机完全区组设计，在旱作条件下对12个面包小麦品种进行评价，其中3个重复为祖母试验，3个农民田各1个重复为母亲试验。两个试验的株高、穗粒数、百升重、千粒重、叶锈病、黄锈病和成熟期在基因型间均存在极显著差异。经农民和研究人员选择，HAR3730 (5.4 t ha-1)、ETBW5518 (5.3 t ha-1)、plcaeor (4.8 t ha-1)、ETBW5521 (4.7 t ha-1)、ETBW5520 (4.4 t ha-1)和HAR1685 (4 t ha-1)产量高于对照品种Kubsa (HAR1685)。开发的参与式面包小麦品种选育解决了农民参与的诸多制约因素，设置参数、选育优种、评价优种的表现，确定优种并加速了农民选育品种在Marwoled Kebele的推广。因此，在Marwoled Kebele推广高产选育品种是小麦品种多样化的必要条件，以应对该地区小麦系统中不断变化的病原菌和流行病。关键词:参与式选择，面包小麦，品种选择。

Some agro-biological and technological characteristics were determined for three Chardonnay clones selections, including 95, 124 and 277, cultivated in the Skopje vineyard region, the R. Macedonia (during the period from 2006 to 2008). A certificated seedling material was introduced from France in 1999/2000, cultivated and studied at the vineyards of the Department of Viticulture and Oenology, Institute of Agriculture, Skopje. The aim of the study was to apply optimal agro-technical and ampelotechnical measures and to compare characteristics of the three Chardonnay clones (95,124,277) cultivated in the same agro-ecological conditions. Different values of the examined characteristics were observed because of the selection specification as well as the ecological conditions during the period of the study. It was found that the yield was most stable for the clone 277 with a coefficient of variable 14.4, and the biggest variation of 21.7 was noticed for the 124 clone. Considering the chemical composition, more significant variation was observed for sugar content in the grape must from the clone 277, while insignificant variations were noticed for total acids in the must of all clones studied. The content of alcohol in the wines ranged from 12.88 vol% in the clone 277 to 13.95 vol% in the clone 95 for the examined period, thus insignificant variations were found in the three clones. Wines from all three clones for the vintage 2006 had greater contents of total extract and, for the examined period, wines with most extract for the clones 95 (21,30 g/L) and 277 (21,20 g/L). The wine made from the 277 clone was with the highest wine-tasting rating of 17.97 points.

Mycotoxins are toxic metabolites produced by some species of mould genera such as Aspergillus, Penicillium and Fusarium, which invade crops in the field and may grow on foods during storage under favorable conditions of temperature and humidity. They are regularly implicated in toxic syndromes in animals and humans as resulting from the intake of mycotoxins are known as mycotoxicoses, aflatoxins, ochratoxins, trichothecenes, zearalenone, fumonisins, tremorgenic toxins, and ergot alkaloids are the mycotoxins of greatest agro-economic importance. Nuts and dried fruits such as apricot, dates, walnuts, peanut, pistachios, figs, raisins, and etc are consumed as snacks as well as part of the ingredients of certain dishes in our daily diet, which are contaminated by moulds and their maycotoxins. This review attempts to describe some major moulds and their mycotoxins, which can contaminate the nuts and dried fruits. Also the diseases (mycotoxicoses) caused by these mycotoxins due to utilization of contaminated nuts and dried fruit has been well.

This study aimed to investigate the effects of tow nanoparticles (NPs) on the absorption,accumulation, reproduction of the Eisenia fetida. A 4×2×2 factorial experiment in a randomized completeblock design with three replications was conducted. The factors included in the experiment are the content ofNPs at four levels (0, 0.4, 0.8, and 1.2gr/kg weight of substrate), the type of NPs at two levels (CuO and ZnO)and the type of substrates at two levels (cow manure and spent mushroom compost (SMC)). After preparingthe substrates, adult worms were added to each pot that has 6kg of each type of substrates. The aqua solutionof NPs was added to the cultures. The NPs effects on the overweight, mortality, accumulation and reproductionwere measured at the end of seven- and fourteen-day two periods after exposure to NPs. The earthwormtissues were enhanced with increasing the NPs concentration. The increases were more in cow manure thanSMC, and the accumulation of ZnO were more than CuO. The number of the earthworm egg decreased in both7th&4th days through increasing the NPs concentration. The ZnO were more effective in reducing thereproduction than the CuO in the seventh day after the substrates treatment. Overweight decreased in bothseventh and fourteenth days through increasing the NPs concentration. Nano CuO was more effective inreducing the overweight than nano ZnO, The decrease of the worm tissues in the SMC substrate was morethan the cow manure substrate in the fourteenth day after the treatment
