The increasing food demands from an expanding population necessitate global efforts to increase crop production and ensure food security. The rate of nitrogen (N) fertilizer application is strongly related to crop yield. However, although the application of N fertilizer significantly increases the number of tillers in rice, late emerging tillers usually produce lower yields compared with early ...

Seven F3 progenies and their 8 parental lines of spring wheat were evaluated for some genetic parameters viz., coefficient of variability (Cv), genetic variance (Vg), heritability percentage (h %) and genetic advance (GA) in 7 quantitative characters (grain yield and its associated traits). Highly significant (p≤0.01) differences were observed for all the characters viz. plant height, number of...

why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...

A field experiment was conducted in 2010, to evaluate the effects of plant density (D1, D2 and D3: 8, 14 and 20 plant/m2) on field performance of Sorghum under different nitrogen application rates (N1, N2 and N3: application of 40, 80 and 120 kg/ha Nitrogen, respectively). The experiment was arranged as factorial based...

The geometrical structure of plant canopies has many implications for plant functioning, microclimatic conditions, and plant-pathogen/herbivore interactions. Plant geometry can be described at several scales. At the finest scale, canopy structure includes the shape, size, location, and orientation of each organ in the canopy. This data set reports the three-dimensional (3-D) geometry of a set o...

Background and purpose:: This research was conducted to evaluate the effect of Piriformospora indica fungus (P. indica) and Rhodococcus erythropolis (R. erythropolis) bacteria on bio-remediation of pyrene in a Pb-polluted soil that was treated with tire rubber ash. Method: Treatment consisted of applying tire rubber ash at the rates of 0 and 300 mg/kg soil, soil polluted with pyrene at the amo...

this study attempts to investigate the effect of peers’ revision in comparison to that of the teacher, and whether peers’ comments and teachers’ comments facilitate students’ revision? if yes, which one is more effective? also attempts have been made to see which aspects of language are more highlighted by peers versus teachers when commenting. besides, it is investigating the student’s attitud...

Identification and classification of genetic source are important in plant breeding and genetic diversity. In order to evaluate genetic diversity of 48 Facultative wheat genotypes belong to north of IRAN, an experiment was done using 10 ISSR primers in the genetic laboratory of Gonbad Kavous University. Out of 62 produced fragments, 41 fragments were polymorphic. The number of polymorphic bands...

Cadmium is a toxic unnecessary element for humans and plants which is easily absorbed by plants. Genetic variation in cadmium accumulation provides an opportunity for breeding programs to select genotypes with low cadmium. Due to the high cost of plant tissue analysis to determine the amount of cadmium, use of markers to make efficient selection of low cadmium accumulating genotypes is an effec...
