Alternaria species are common saprophytes or pathogens of a wide range of plants pre- and post-harvest. This review considers the relative importance of Alternaria species, their ecology, competitiveness, production of mycotoxins and the prevalence of the predominant mycotoxins in different food products. The available toxicity data on these toxins and the potential future impacts of Alternaria...

The scope of this paper is to describe the work of manual sugarcane harvesters, assessing the nutritional behavior and body composition between the beginning and the end of the harvest. A descriptive longitudinal study was made of harvesters in Piracicaba, São Paulo, Brazil, who answered a socio-demographic questionnaire and authorized measurement of Body Mass Index, Body Fat Percentage and Arm...

seed and oil yields, their components, and the relationships among trait performance were determined in 25genotypes of winter type oilseed rape (brassica napus l.). the experiment was carried out at the agricultural and natural resources research center of east azerbaijan, iran, in two consecutive growing seasons 2009-10 and 2010- 11. significant differences were observed in plant height, numbe...

objective: field experiment was conducted in 2009 to investigate the effects of plant density and weed interference on morphological characteristics and yield of corn (zea mays, l.) at research station of university of tabriz, tabriz, iran. methods: the experiment was arranged as split plot based on randomized complete block design with three replications. plant density (d1, d2, d3 and d4: 5, 7...

this study evaluated direct drilling planters used for wheat cultivation in khorasan-e razavi province. a randomized complete block design with three replications was used. the treatments were direct drilling of wheat plants into wheat residue using the following direct planters: (1) sfoggia (13-25), (2) baldan (spd3000), (3) tondar (spd 2500), (4) semeato (shm 11/13). the parameters measured w...

in order to study the effect of vermicompost containing copper oxide and zinc oxide nanoparticles on was beans, in an experiment factorial were done based on a randomized complete block design in three replications. the experiment treatment were as follows: nanoparticles in 4 levels (0, 0.4, 0.8 and 1.2 g/kg weight of substrate), vermicompost in 3 levels (2.5, 5 and 7.5 g/kg-1 weight of substra...

in this study, the effects of weed control treatments and plant density on lentil (lens culinaris) yield and yield components as well as weed control efficacy were investigated. the study was conducted according to a split-plot arrangement based on randomized completely block design in three replicates in karaj in 2007-2008. the weed control chemical treatments in four levels (trifluralin herbi...

According to urgent need of corn to nitrogen and since this element play a main role in improving of yield corn, thus, in order to investigate the effect of different levels of urea on yield and yield components of corn 704, an experiment was conducted randomized block with three replications in cropping year of 2012. Experimental treatments included six levels of urea (0, 30, 60, 90, 120 and 1...

Bio-fortification of food crops is a cost-effective and sustainable agricultural strategy to decrease malnutrition arising from micronutrients deficiencies. Accordingly, the pot experiments have been conducted to investigate the effectiveness of various foliar-applied iron (Fe) fertilizers in increasing agro-morphological traits and grain micronutrients concentrations of bread wheat plants unde...
