The predicted ongoing increase of atmospheric carbon dioxide levels is considered to be one of the main threats to biodiversity due to potential changes in biotic interactions. We tested whether effects of intraand interspecific planting density of the calcareous grassland perennials Bromus erectus and Carex flacca change in response to elevated [CO2] (600 ppm) by using factorial combinations o...

Trap crops that stimulate nematode egg hatching but not reproduction have been reported as an effective means for managing certain nematodes. Studies were carried out at two field sites each year in 1998 and 1999 to evaluate the potential of trapping the soybean cyst nematode (Heterodera glycines) with soybean and pea in the corn year to manage the nematode in Minnesota. The trap crops were pla...

Rapeseed is one of the most important edible oil crops in the world and the seed yield has lagged behind the increasing demand driven by population growth. Winter oilseed rape (Brassica napus L.) is widely cultivated with relatively low yield in China, so it is necessary to find the strategies to improve the expression of yield potential. Planting density has great effects on seed yield of crop...

considering importance of baby corn as a new food, this study was conducted to evaluate effect of different sowing date; planting density and harvest methods on growth and yield of baby corn ksc403su varieties in agricultural research center and natural resources of khorasan razavi province during on 2007-2008. was considered at three levels of sowing date (14th  june, 3th  july, 24th july) as ...

Field experiments were conducted to evaluate the efficacy of five nematicides for the management of Rotylenchulus reniformis and for their effects on growth, development, and yield of cotton. Treatments included 1,3-dichloropropene (1,3-D), fenamiphos, phorate, terbufos, aldicarb, and 1,3-D + aldicarb. Average R. reniformis population densities across all treatments increased from 5,284 at 10 d...

an experiment was conducted as a split – split plot in form of a randomized block design with four replications in cilakhor region of iran in 2004. the main factor was the seed planting date with three levels (5, 12 and 25 april), sub factor was the crop density with two levels (160,000 and 250,000 pl/ha) and sub-sub factor was the crop arrangement with two levels (equidistant and non-equidista...

Many secondary plant compounds are synthesized in response to stressed growing conditions. We tested the feasibility of exploiting this feature in a novel strategy for the commercial production of the plant alkaloid galanthamine. Experimental lines of Narcissus pseudonarcissus were established under marginal upland permanent pasture at four different sites. Over 80% of bulbs successfully establ...

These data and analyses support the research article "Wild ungulate herbivory suppresses deciduous woody plant establishment following salmonid stream restoration" Averett et al. (2017) [1]. The data and analyses presented here include: (1) planting density, survival and growth (two years post restoration) of riparian plantings along an ~11 km stream reach in northeastern Oregon as a function o...
