A large body of research has documented the effect of seed priming ongermination, emergence and crop yield. In such research, seed priming has beenfound to have a positive, negative or no effect. Meta-analysis can help tosummarize and interpret a collection of experiments. The aim of this study was toconduct a meta-analysis to synthesize published data from studies addressing theeffect of seed ...

prediction of seasonal weed seedling emergence patterns is useful in weed management programs. this study was carried out in research fields of islamic azad university – karaj branch in 2009-2010. five crop fields were chosen including: barley, sugar beet and three wheat fields and in each fields between 3 to 5 sites selected randomly. three quadrates were fixed in each sites for studying weeds...

recently, increase in crop production depends on better seedling establishment, emergence rate and uniformity. thus, an experiment was carried out in a randomized complete block design with 8 fertilizer treatments and 4 replications in 2008 at sari agricultural sciences and natural resources university. the aim of this research was to evaluate effect of vermicompost (vc) on bush bean seedling e...

In order to test the feasibility of computer simulation in field maize planting, the selection of the method of single seed precise sowing in maize is studied based on the quadratic function model Y = A×(D-Dm)2+Ym, which depicts the relationship between maize yield and planting density. And the advantages and disadvantages of the two planting methods under the condition of single seed sowing ar...

in order to evaluate the response of emergence rate of oil seed rape seedlings to temperature, a pot experiment was conducted to assess the relationship between emergence rate of three rape seed cultivars (apetalous flower, rgs003 and syn3) by using a non-linear regression against temperature variation. six models (tooth shape, segmented, beta, curve, quadratic and cubic) were used and the supe...

this research evaluated the effects of gibberellin (ga3) and abscisic acid (aba) on emergence capability, rate of emergence, vigor index and some physiological characters of chickpea seedling (cicer arietinum l.) in a field experiment (as split) under dry and irrigated conditions. seeds were primed with 0, 50, 100 and 150 ppm of each phytohormones. examined chickpea cultivar was azad. the resul...

the main objective of this study was using of canonical correlation analysis (cca) to find relations between 15 different variables of seed emergence and seedling growth related characteristics of seven important crop that were classified in three groups. the studied groups of variables were included physical characteristics (seed weight, seed length, seed density, water absorption and water co...

1 We examined how seed size and seedling growth rate influence recruitment success of neotropical pioneer species. We investigated the soil seed bank, and followed seedlings from emergence and establishment to the sapling stage in artificially created gaps in secondary forest on the Barro Colorado Nature Monument, Panamá. 2 To simulate microsite variation within gaps, litter addition/removal an...
