an experiment was conducted in bandar kyashahr research field in 2002 to evaluate the effects of plant density and planting pattern on weed populations and yield of peanut (arachis hypogaea l.). the experiment was of a randomized complete block design with three replications. a factorial trial with two factors of planting pattern (square and rectangular arrangements) and plant density (3, 5.3, ...

In this study, the effect of some processing parameters on bulk density, particle density, particle size and some of powder reconstruction properties such as dispersibility, Wettability and water solubility index of spray dried barberry (Berberis vulgaris) juice powders were investigated. A Pilot Spray Dryer (Two- Flow nozzle, counter- current, one cyclone) was employed for the spray d...

background: in megavoltage radiotherapy rooms, ordinary concrete is usually used due to its low construction costs, although higher density concrete are sometimes used, as well. the use of high-density concrete decreases the required thickness of the concrete barrier hence, its disadvantage is its high cost. in a nuclear reactor, neutron radiation is the most difficult to shield. a method for p...

according to the contradictory reports of researchers, tillers may have positive or negative effect on wheat yield. thus, this study was conducted to investigate the role of tillers on wheat yield under two row spacing of 12.5 and 25 cm and four plant densities of 125, 250, 375 and 500 plants per m2, at gorgan university of agricultural sciences and natural resources farm in anbare-ololum reign...

It has been suggested that a latitudinal gradient exists of a low density of snags and high density of naturally-formed tree-cavities in tropical vs. temperate forests, though few cavities may have characteristics suitable for nesting by birds. We determined snag and cavity density, characteristics, and suitability for birds in a tropical dry forest biome of western Mexico, and evaluated whethe...

in order to evaluate the effects of intercropping of maize- peanut, weeding and their planting design on weed population dynamics, an experiment was conducted as a factorial experiment in the form of rcbd with three replications at the research farm of agriculture center of zabol university (iran) in 2012. the treatments including sowing system in four levels as first factor  (sole maize, sole ...

Tropical and subtropical dry forest life zones support forests with lower stature and species richness than do tropical and subtropical life zones with greater water availability. The number of naturalized species that can thrive and mix with native species to form novel forests in dry forest conditions in Puerto Rico and the US Virgin Islands is lower than in other insular life zones. These no...

to study the effects of plant density and nitrogen rates on the ability of canola (regent  cobra; an inbred variety) to compete with weeds, an experiment was conducted as a factorial complete block design with four replications. the treatments included four levels of plant density at 150, 190, 230, and 270 plants m-2, and four levels of nitrogen (n) fertil-izer at 0, 46, 92, and 138 kg ha–1. r...
