the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
to evaluate the effect of environment on the general and specific combining ability of virginia tobacco genotypes, five varieties were intercrossed in combination in 2007 in a half – diallel design. in 2008, the ten f1 population and the five parental lines were sown in two different conditions (drought stress and non-stress) using a complete randomized block design with three replications and ...
structure of alpha lattice designs makes removing the effects of incomplete blocks from residual effect of plots, and maximizes precision of comparison between genotypes at the same incomplete block. this investigation was conducted to study the international chickpea germplasm, for finding desirable lines regarding seed yield and other traits. two trials including cien-la-2010 and cien-s-2010 ...
in order to investigate the effects of humic acid on three tomato varieties, a field experiment was conducted as a split-plot design experiment based on randomized complete block design (rcbd) with 3 replications in ahmad abad part in khorasan razavi, during 2009-2010 .two factorial combinations were four levels of humic acid (0, 1, 1.5, and 2 kg.ha-1) and three tomato varieties (super ch, este...
general and specific combining ability of five fertile male (lines) and two male sterile (tester) of rice were evaluated for 10 important morphological traits as well as yield and yield components in a randomized complete block design with three replications. results revealed that general combining ability effects were highly significant (p
Turfgrass is important in urban landscape and by considering that organic matter has a important roll in improving physical and chemical soil characteristics using an organic matter instead of manure and MSW seems necessary .in this research the possibility of using new method of culture such as hydromulching (i.e. mixing seed, organic matter, water, and fertilizer and then distributing it) spe...

to study the genetic variation among 24 genotypes of tall fescue (f. arundinacea), a randomized complete block design of three replications was conducted under spaced plant conditions in karaj research institute of alburz, iran. analysis of variance showed high and significant differences (p
this study was carried out to investigate flower yield and yield components in iranian rosa damascena using 20 genotypes, collected from different regions of iran and grown in drylands and deserts research station of kashan, iran, using a randomized complete block design with three replications in 2007-2008. flower yield per plant, number of flowers per plant, plant height, leaf length, width, ...
the aim of this study was to evaluate the effects of different levels of citrus limon essential oil on nutrient digestibility, blood and ruminal metabolites in male holstein calves. this study were conducted using four male holstein calves, each fitted with a permanent rumen cannula (average body weight 650±20 kg) that received experimental diets including control with 600, 800 and 1000 mg/d le...
