in order to evaluate the effect of different nitrogen application methods on yield and yield components of winter wheat, a field experiment with split plot arrangement in randomized completely blocks design with four replicates was conducted during 2006-07. basal dressing in three levels (with no basal dressing, strip and distributing nitrogen fertilizer) as main plot and top dressing in six le...

Gibberellin 2-oxidases (GA2oxs) regulate plant growth by inactivating endogenous bioactive gibberellins (GAs). Two classes of GA2oxs inactivate GAs through 2beta-hydroxylation: a larger class of C(19) GA2oxs and a smaller class of C(20) GA2oxs. In this study, we show that members of the rice (Oryza sativa) GA2ox family are differentially regulated and act in concert or individually to control G...

Abstract In grasses, biomass and grain production are affected by plant architecture traits such as tiller number, leaf size orientation. Thus, knowledge regarding their genetic basis is a prerequisite for developing new improved varieties. Mutant screens represent powerful approach to identify factors underpinning these traits: the Hor TILLUS population, obtained mutagenesis of spring two-row ...

Fertilizers usually enhance potassium (K) content and other naturally occurring radioactive materials in agricultural fields that eventually enter the human food chain through plants. In this study, pot-grown rice plants planted in soil that is relatively high in natural radioactive content was used to estimate the individual influence of fertilizer applications on the uptake of 226Ra, 232Th, a...

The work studies the effect of microbiological preparations based on culture B. subtilis and megaterium growth processes, photosynthetic parameters, grain productivity oats. Field tests were conducted in 2019 conditions a micro plot experiment North-West Russia. Microbiological introduced by soaking seeds treating plants third leaf stage with 1 ml/l.The research finds that introduction leads to...

a field experiment was conducted to evaluate the effect of varying doses of haloxifhope-r-methyl ester herbicide on grass weeds grown at various stages in 2011-2012 growing season in research farm of college of agriculture, shiraz university. the study was carried out as split split plot based on randomized complete block design with three replicates. treatments were haloxifhope-r-methyl ester ...
