Mapungubwe Cultural Landscape (MCL) woody vegetation was characterized to establish structural and compositional attributes. Stratified random sampling based on major soil types was used and nine plant variables were measured in 137(20x30) m2 sampling plots; these being genera, species and family names; basal circumference; plant height; depth and diameter of tree canopy; number of s...

in order to evaluate the interference effect natural population weeds and plant density, an experiment with randomized complete block design in factorial arrangement with 4 replications was conducted in 2006 in a field experiment at ramin agricultural and natural resources university, khouzestan. treatments included two factor, plant density of corn at three levels (4, 7 and 10 plants m-2) and ...

, present study was performed in order to determine effects of different amounts of irrigation water, plant density and planting pattern on yield, yield components and water use efficiency (wue) of corn, variety single cross 700 (700ksc) using drip irrigation systems (tape) , in the research station of islamabadgharb in two consecutive years (2011-2012). the project was in the form of split blo...

Net intraspecific density dependence experienced by insect herbivores at the scale of single plants can be a function both of induced resistance in the plant and other interactions among individual herbivores. Theory suggests that non-linearity in the form of this density dependence can influence the effects of plants on herbivore population dynamics. This study examined both net density depend...

Taro (ColocasiaesculentaL. Schott) is a perennial root crop that belongs to Araceace family. It is widely cultivated as a staple food in Africa, Asia and pacific Islands. Despite its importance, there is limited information on many aspects of the crop. In order to obtain data that can support improved and sustainable taro production, a field trial was conducted to study the effects of ...

Neighboring plants can affect the likelihood that a focal plant is attacked by herbivores. Both the density of conspecific neighbors (resource concentration or dilution effects) and the relative density of heterospecific neighbors (associational effects or effects of neighbor frequency) within the local neighborhood can affect herbivore load and plant damage. Understanding how these neighborhoo...

in order to investigate effects of plant density and fertilizer rates on agronomic characteristic and yield tobacco (nicotiana tabacum) (cv k326) an experiment was conducted in the experimental field of tirtash research and education center. design of experiment was randomized complete block with factorial arrangement with three replications and 36 treatments conducted in 2007 year. treatments ...

1. Pollinator visitation patterns in relation to variation in floral display size may be modified both quantitatively and qualitatively by local plant density. In this study four measures of pollinator response by Bombus spp. (plant visitation rate, bout length, proportion of flowers visited, flower visitation rate) were investigated under two or three different plant densities in two consecuti...
