To study the effects of plant densities and planting orientation on the seed and forage yield of sorghum, an experiment was conducted at Hossein- Abad – Shahcal village –90 kilometers south of Bam-in 2002. The experiment was a factorial with randomized complete block deisgn and three replications. The treatments were: orientation with three levels (South-North, East – West, Northeast – Southwes...
in order to study the effect of mallow weed competition and nitrogen (n) rates on grain yield and yield components of wheat cv. chamran, a field experiment was conducted in 2009. the experiment was designed as a split-plot with three replications and additive series. the n application rates were assigned in the main-plots (50, 100, 150 and 200 kg.n.ha-1) and sub-plots consisted of target common...

in this study theeffect ofdrought stress was investigated on grain yield and oil rate and protein percentage of four varieties of castor in the climatic conditions of damghan. the experiment was done in the research farm of damghan islamic azad university(iran)in 2011 assplit plots in a randomized complete block design with three replications. the main plots of drought stress were 5, 10 and15 d...
The spatial distribution of individuals of any species is a basic concern of ecology. The spatial distribution of parasites matters to control and conservation of parasites that affect human and nonhuman populations. This paper develops a quantitative theory to predict the spatial distribution of parasites based on the distribution of parasites in hosts and the spatial distribution of hosts. Fo...
BACKGROUND Data are lacking on the efficacy and safety of a combination chemotherapy regimen consisting of oxaliplatin, irinotecan, fluorouracil, and leucovorin (FOLFIRINOX) as compared with gemcitabine as first-line therapy in patients with metastatic pancreatic cancer. METHODS We randomly assigned 342 patients with an Eastern Cooperative Oncology Group performance status score of 0 or 1 (on...
to achieve optimal yield and high production in wheat, need to adapt the plant's vegetative and reproductive growth stages to environmental conditions and increase use efficiency of production factors by desirable density. in order to study the effect of plant density on extinction coefficient and radiation use in modern and old wheat (triticum aestivum l.) genotypes, an experiment was conducte...
one of the major sectors of water loss is the loss of rain runoff. kirkby (2001) the effect of soil surface characteristics in the production of runoff in time and space scales concluded that soil properties such as undulating, soil texture and structure on the amount and spatial pattern of runoff are effective. in this research that was conducted in the latian watershed, twenty experimental pl...
Patterns of leaf carbohydrate partitioning and nodule activity in soybean plants grown under natural conditions and the irradiance level required to produce sufficient carbohydrate to obtain maximum rates of apparent N(2)-fixation (acetylene reduction) were measured. Soybean plants, grown outdoors, maintained constant levels of leaf soluble sugars while leaf starch pools varied diurnally. When ...
