for study the effect of arbuscularmycorrhiza fungi a factorial experiment in a randomized complete block design with four replications was carried out in the summer of 1389 at the agricultural research station in city of zahak. the experiment included two factors; the first factor was inoculated glomus mossea mycorrhiza and no-inoculated one. the second factor was in four varieties of corn: s.c...
The aim of investigation was to determine the effects of aspect (north and south) on some morphological [plant height (cm), number of stems per plant, main stem diameter (mm), number of leaves per main stem, petiole length (cm), leaflet length (cm), leaflet width (cm), leaf: stem ratio] and chemical [crude protein (%), crude cellulose (%), calcium (%), phosphorus (%), potassium (%) and magnesiu...
In order to study the effects of foliar spraying of Pseudomonas fluorescens bacteria on quantitative characteristics, yield and yield components of two rice cultivars, a factorial experiment, based on completely randomized design with three replications, was conducted in Rice Research Institute of Rasht, Guilan province, Iran. In this experiment, two rice cultivars (Khazar and Hashemi) were spr...
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...
sainfoin (onobrychis viciifolia scop.) is a perennial forage legume has recognized for its feed value and high stability. this experiment was conducted to investigate the relationship among morphological and agronomic traits using multivariate statistical methods including correlation, regression and factor analysis. twenty one accessions of sainfoin were evaluated in a randomized complete bloc...

Planting pattern through changing vegetative growth and utilization of environmental resourses affects yield components and seed yield. These effects were studied in the spring of 2000 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with a split plot layout and three replications. Main plots consisted of three row distances (30 cm...
Objective: A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Methods: Two inter-row spacings (60 and 90 cm) and three intra-row spacings (30,...
this study was carried out to investigate flower yield and yield components in iranian rosa damascena using 20 genotypes, collected from different regions of iran and grown in drylands and deserts research station of kashan, iran, using a randomized complete block design with three replications in 2007-2008. flower yield per plant, number of flowers per plant, plant height, leaf length, width, ...
Many experiments have been carried out to decrease the negative effect of drought stress and obtain suitable growth under water deficit conditions. Application of plant growth regulators (especially growth retardants) is one of the proposed methods. This study was conducted to investigate the effect of Cycocel application on growth of two olive cultivars (Shengeh and Roghani) under water stress...
