The longer network lifetime of Wireless Sensor Networks (WSNs) is a goal which is directly related to energy consumption. This energy consumption issue becomes more challenging when the energy load is not properly distributed in the sensing area. The hierarchal clustering architecture is the best choice for these kind of issues. In this paper, we introduce a novel clustering protocol called Mar...

the present investigation was carried out to study the variability, heritability, correlations and path coefficient analysis in 14 kabuli type chickpea genotypes during three successive cropping seasons (2011-14), in a randomized complete block design with four replications. combined analysis suggested significant differences between genotypes for most of characteristics. the highest phenotypic...

in order to study of genetic variation and identification of yield components in chickpea, a trial consists of 96 accessions of chickpea received from iranian gen bank (seed and plant improvement institute) along with five checks (arman, bivanij, jam, hashem and ilc-482) was conducted based on an augmented design in 2005-06 cropping season at research farm of agricultural college, razi universi...

in order to determine the relationship between the variables grain yield and biological yield and some important agronomic traits, and to find the direct and indirect effects of important agronomic traits on both grain and biological yields, 364 soybean genotypes (3 planting dates) were studied. the study was based on a design augmented with 3 checks and 6 blocks implemented, in seed and plant ...

adjustment of plant density is an important base on light, water and soil nutrients for increasing seed yield. to determine of plant density in new red bean lines (phaseolus vulgaris l.), this experiment was conducted as factorial in randomized complete block design (rcbd) with three replications at lordegan region (chaharmahal and bakhtiari province) in 2004-2005. factors were new red bean lin...

in order to investigate the effect of seed rate on seed yield and yield components of three rapeseed varieties, a split- plot experiment was conducted in randomized complete block design with four replicates during 2008-2009 at baykola agricultural research station, neka, mazandaran province. in this experiment four seed rates (5, 7, 9 and 11 kg.ha-1) as main plots, three rapeseed cultivars (hy...

Dispersal is a major and critical process in population biology that has been particularly challenging to study. Animals can have major roles in seed dispersal even in species that do not appear specifically adapted to animal-aided dispersal. This can occur by two processes: direct movement of diaspores by animals and modification of landscape characteristics by animals in ways that greatly inf...

in order to evaluate of yield and yield components of chickpea genotypes, path analysis set to facilitate the selection of high yielding varieties in limited irrigation. research was canducted in 2010-2011 growing season at the agricultural research station, ferdowsi university of mashhad, by using seven drought tolerante genotypes (recommended from a previous research) in a randomized complete...
