in order to evaluate the effect of water deficit and different fertilizer levels on yield and some agro-morphological characteristics of moldavian balm, a split plot experiment was conducted in a randomized complete block design with three replications at the research farm of shahrekord university during 2013-2014 growing season. main factor was three levels of irrigation regimes including: 100...

In the present study effects of production history on tuber sprout, root, stem development and crop yield of seed potato cultivars Fambo and Van Gogh were investigated in the High Grade Area of Finland (64.9 N, 25.4 E). The haulms of seed potatoes were destroyed at the time of flowering (50 days after planting, DAP), three weeks after flowering (75 DAP) and as a control the haulm was left to na...

According to the result of current study, plant height, canopy, stem girth, number primary branches and total dry matter at 30 DAT, 60 90 DAT were recorded maximum with application 100% RDF. The yield parameters, such as a flowers per plant, yield/plant, yield/plot yield/ha., flowering minimum days first flower bud appearance, 50% flowering, harvest duration, i.e., highest gross return/ha net b...

to study the effect of urea application in safflower (carthamus tinctorius) and determination of effective traits on its yield, a factorial experiment based on randomized complete block design in three replications was conducted in tabriz, iran, during 2012. studied factors were urea rate levels as 100, 150 and 200 kg/ha and urea application times 100% in sowing time, 50% sowing time + 50% stem...

The paper presents the results of a 2016–2018 study to determine effect share components in mixture and harvest date on weed infestation yield mixtures field pea with spring triticale. Two factors were studied experiment: proportion mixture: – clean sowing 100%, triticale 75% + 25%, 50% 50%, 25% 75%; harvesting date: flowering stage (BBCH 65), flat green pod 79). obtained allow us conclude that...

BACKGROUND The effect of herbivory on plant fitness varies widely. Understanding the causes of this variation is of considerable interest because of its implications for plant population dynamics and trait evolution. We experimentally defoliated the annual herb Arabidopsis thaliana in a natural population in Sweden to test the hypotheses that (a) plant fitness decreases with increasing damage, ...
