Diallel analysis was used to estimate the combining ability, gene action, gene number, heritabilties and other genetic parameters of a set of wheat genotypes. For this purpose, nine parents and their 36 crosses were evaluated for 9 traits in a randomized complete block design with three replications in 1996. The analysis of variance revealed significant differences among all genotypes for all ...
In order to study the relationships between grain yield and its components of Aegilops cylindrica, 48 accessions of this plant species was studied in an experimental augmented design based on randomized complete block designwith4 replications under normal and drought stress conditions in the Agricultural Research Station of Ilam University. The results of correlation analysis between the traits...
A field experiment was conducted during kharif season of 2010 and 2011 to investigate the optimization of nitrogen levels under different age of seedlings transplanted on growth, chlorophyll content, yield and economics of hybrid rice. Fifteen treatment combinations consisted of three levels of seedlings age (10, 20 and 30 days) and five levels of nitrogen viz. N0, N50, N100, N150 and N200 kg h...
| Supernode transformation has been proposed to reduce the communication startup cost by grouping a number of iterations in a perfectly nested loop with uniform dependencies as a supern-ode which is assigned to a processor as a single unit. A supernode transformation is speciied by n families of hyperplanes which slice the iteration space into parallelepiped supernodes, the grain size of a supe...
Early autumnal and late spring frosts usually impose damages to wheat production in North-West of Iran. In order to investigate cold tolerance of wheat genotypes, two laboratory and field experiments were carried out at three planting dates of 12 Oct. and 1 and 21 Nov. 2007 in Saatlu Agricultural Research Station on 15 genotypes with winter, facultative and spring-growth types. Arrangement of t...
in order to investigate the yield and yield components of four lentil genotypes (local line, local bulk, ill-10314 and ill-6037 genotypes) as affected by three urea nitrogen levels including 0, 45 and 90 kg ha-1, a factorial experiment based on randomized complete block design with three replications was carried out in agriculture and natural resources research center of ardabil, during 2008. b...
Based on several simplifying assumptions, a stochastic approach is developed that allows an estimation of the effects of non-regular spatial patterns of the distribution of individual plants on the mean value (K ) of trait per area. In this approach, two random variables are attached to each plant: single plant trait measurement (E) and individual space per plant (A). The latter is estimated by...
In order to study agronomic and morphological traits in maize hybrids in Hammedan, two early (108 and 301), three medium (604, 647 and TWC647) and two late maturing (704 and 711) hybrids were evaluated in a randomized complete block design with three replications in Agricultural and Natural Resources Research Station in Hammedan in 2005. 33 morphological and phonological traits were recorded fr...
In order to study the correlation of agronomic, morphologic and physiologic traits and their effects on grain yield of rice genotypes in two environments (favorable irrigation and water stress), 49 genotypes were evaluated using a completely randomized block design with 3 replications in two experimental conditions. All practices and conditions were the same for the two experiments with the exc...
in order to study the effect of the usage of vermicompost and mycorrhiza fertilizer usage on yield quantity and quality of soybean cultivar l17 in water deficit stress condition, an experiment was conducted as plots in a split at randomized complete blocks with four replications in agricultural research center in 2013 in khoramabad. the experiment treatments including irrigation in three levels...
