This experiment was conducted, to study the effect of planting time and planting density on savory (Satureja sahendica Bornm.) in 2012 in Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran. The experiment was carried out in split plot in time in the form of a randomized complete block design with three replicates. The main plots were planting times in two levels ...

there are varying patterns for growing different varieties of branched or non-branched sesame. this experiment was conducted during a two-year period (2000-2001) to identify the optimal practice for cultivation of the uni-branched sesame in the safi-abad agricultural research center, khuzestan province. the statistical design was set up as strip-plot in a randomized complete block with four rep...

in order to study the effect of nitrogen rate and plant density on morphological traits and essential oil and fruit yield of coriander, a split-plot experiment was carried out in research field of islamic azad university, birjand branch, birjand, iran in 2010 based on a randomized complete block design with three replications. the main plots were nitrogen rates at four levels (0, 40, 80 and 120...

a field experiment was conducted during 2003-4, 2004-5 cropping seasons evalute the effects of plant density on growth and yield of different rapeseed cultivars. the study was carried out at ramin agriculture and natural resources university (35 km from northeast of ahwaz). the experiment was in the form of split plots' based upon a complete randomized block design of four replications. ma...

1. Genotypic diversity in plant populations is known to enhance plant performance and ecosystem function. Nonetheless, the effect of genotypic diversity has rarely been examined across a population’s lifecycle despite the expectation that changing conditions, such as population density, will alter the benefits of diversity. 2. We simultaneously manipulated a component of genotypic diversity (ri...

This work was aimed at assessing whether in silage maize it is possible to replace precisionplanting with a volumetric seeding in the perspective of developing hybrid machines to strip tilland sow both high density crops like winter cereals and low density crops like maize. This inorder to reduce the number of machines in the farm, simplify logistics and reduce amortizationcosts. Two experiment...

in order to evaluate the variation of some of quantitative and qualitative traits of different varieties of linseed under different plant densities, an experiment was conducted in the research station of the faculty of agriculture in shahrekord univerity in 2009. this experiment was arranged as factorial in rcbd design with three replications. four linseeds originated from australia, canada, fr...

this research was investigated to evaluate growth indices and competitive ability of two wheat ) triticum aestivum l. (cultivars in interference with two species of narrow and broad leaf weeds as two separated experiments based on a randomized complete block design with three replications at agricultural faculty of bu-ali sina university, during 2008-2009. in both experiments, alvand and sayson...
