Transplantation of eelgrass Zostera marina has become a promising restoration tool since natural recolonisation during the last century failed after massive mortality, due to a combination of a wasting disease outbreak and a sequence of human impacts. We studied the interactive effects of planting density and hydrodynamic exposure on the survival of transplants of an annual population of intert...

With the growing importance of fruits as valuable food resources, attention has been paid in recent years to enhance productivity and quality. Increasing per unit area through agronomic management is one important strategies increase production fruit crops. Keeping this view, review was undertaken improve understanding planting arrangement effect density on quality This will thus provide update...

Planting date of soybean, Glycine max, influenced winter survival of Pratylenchus brachyurus in microplots at two locations in North Carolina. Delayed planting resulted in a linear decrease (P = 0.05) in the numbers of P. brachyurus at soybean harvest. Effects of planting date on nematode numbers persisted over winter, indicating that survival in the absence of a host is density independent. Co...

Planting pattern through changing vegetative growth and utilization of environmental resourses affects yield components and seed yield. These effects were studied in the spring of 2000 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with a split plot layout and three replications. Main plots consisted of three row distances (30 cm...

an experiment was conducted at ecbatan research station in hamedan in two years (1998-99) to study the effects of planting density and methods and also seed clove size on yield of hamedan garlic. the experiment was in factorial 3 x 3x 3 in randomized complete block design with three cultivation methods, three sizes of seeds and three plant densities in three replications. the data were analized...

Baby corn is a premature ear of maize that is harvested as dehusked vegetable corn at 2-3 days after silking before fertilization. No enough attention has been paid to this kind of maize in the literature. In order to investigate the effect of planting density and pattern on yield and some qualitative and morphological traits in baby corn hybrid KSC403su a field experiment was conducted at Coll...

This study was conducted to study and compare the effects of different tillage systems on soil physical properties and wheat yield in dryland conditions. The experiment was carried out in Maragheh Dryland Research Station with 5 treatments and 4 replications based on RCBD for 3 years (2001-2003). The results showed that difference between the treatments in terms of wheat yield was significant, ...

The objective of this study is to analyse the density-dependent dynamics of growth and mortality in an unthinned Eucalyptus grandis spacing experiment on a homogenous site in Zululand/South Africa. Specifically we propose models that describe how the (log) basal area develops in unthinned stands. Our data clearly indicate that mortality varies enormously with planting density. We therefore deve...

Subsoiling is an important management practice for improving maize yield, especially for maize planted at high plant density. However, the affected physiological processes have yet to be specifically identified. In this study, field experiments with two soil tillage (CK: no-tillage, SS: subsoiling) and three planting densities (low: 45000 plants ha-1, medium: 67500plants ha-1, and high: 90000 p...
