shoot:root ratio, dry matter partitioning, growth analysis, and water use efficiency of oat (avena sativa l., cv. walker) was investigated under excessive nitrogen (n) as 200 mg n kg-1 (n1p0), excessive phosphorus as 200 mg p kg-1 (n0p1), and combined 100 mg n+100 mg p kg-1 (n2p2), and the control (n0p0) as check in a pot experiment at dryland agriculture institute, west texas a and m universit...

Trawl fishing contributes to majority of the total fishes’ landings, supporting choice using age, growth determination, and condition factors (K) as part monitoring method for fishes in Malaysia waters. This research specifically examines use length-weight relationship (LWR), K monitor status commercially important LWR, K, age 10 trawl species (Gerres erythrourus, Drepane punctata, Otolithes ru...

given the important role of crop growth indices for explanation of cultivars yield differences in diverse environmental and agronomical circumstances, this experiment was conducted at research field of tarbiat modares university during 2007 growing season. experimental treatments were arranged in split-plot layout based on randomized complete blocks with four replications. in this research, sow...

Objective: The first aim of this study is to describe the length, weight, condition factor, and GSI Alburnus istanbulensis (Battalgil, 1941) in two different connected habitats (stream habitat reservoir lake) Karamenderes River, Çanakkale. second state growth type species sampled using length-weight relationship (LWR) model. Materials Methods: sampling areas are Bayramiç Reservoir tributaries o...

the length-weight relationship (lwr) and condition factors (cf) of 180 the oriental river prawn macrobrachium nipponense collected from southern coasts of the caspian sea from may through september 2012 were studied. shrimp samples were taken and immediately transferred to the laboratory of fish biology at university of guilan for further analyses. length, weight and other external features of ...

Relationships between net plant CO(2) exchange rate (CER) and canopy development were examined in ;jubilee' tomato over the initial 4 weeks of vegetative growth. A comparison was made between two plant groups that were alternatively exposed to 200 or 800 microeinsteins per square meter per second midday irradiation to establish a differential in net CER. Plants exposed to higher irradiation dem...

The kinematic wave traffic flow model for an inhomogeneous road is studied as a resonant nonlinear system, where an additional conservation law is introduced to model time-invariant road inhomogeneities such as changes in grades or number of lanes. This resonant system has two families of waves, one of which is a standing wave originated at the inhomogeneity. The nature of these waves are exami...

The study investigated morphometric and meristic measurements, length-weight relationship (LWR) relative condition factor (Kn) of the Sphyraena obtusata from south-eastern Arabian Sea August 2019 to March 2020. Three hundred fifty two specimens having a length weight range 16.5 – 30.1 cm 29.54 155.20 g, respectively were analyzed for morphological measurements (13 11 meristic), LWR factor. maxi...

Relative growth rate (RGR), leaf water potential (psi w), transpiration rate (Tr), photosynthetic rate (Pn), and stomatal and mesophyll resistances to CO2 exchange were measured or calculated to determine how periodic seismic (shaking) stress decreased dry weight accumulation by soybean (Glycine max [L.] Merrill cv Wells II). Seismic stress was applied with a gyratory shaker at 240 to 280 revo...
