In order to assessment of grain yield and some of morphological characters in safflower genotypes under irrigated and rainfed conditions fifteen spring safflower genotypes were studied using two separate experiments based on randomized complete block design with three replications in 2010-2011 growing season at Miandoab Research Station, Iran. Analysis of variance for each conditions revealed s...
factor is introduced for direct head loss calculation and sizing in dual-diameter laterals of sprinkler and trickle irrigation systems when the hazen-williams equation is to be applied. application of this factor prevents trial and error and uses fewer head-loss equations in calculating the total friction loss and designing dual-diameter laterals. the proposed factor is a function of total num...
safflower is a crop native to iran and could be improved in plant breeding programs by inter-specific crosses. this study was conducted to evaluate genotypes of safflower derived from interspecific hybridization for the relationships between some agronomic traits and yield components. the genotypes were planted according to a randomized complete block design with three replications at the resea...
In order to study the effects of drought stress on agronomical traits and seed yield of new hybrids of sunflower there individual experiments were conducted on nine hybrids of sunflowers under three irrigation regimes (irrigation after 60,120,180 mm evaporation from evaporation pan class A) in 2006. The experiment was a randomized complete block design with 3 replication, performed in the resea...
The effects of application different amount cattle manure on some of quality and quantity characteristics such as plant height, stem diameter, head diameter, biological yield, seed yield, oil in seed and protein in seed on hybrids sunflower hybrids was investigated in 2008. This experiment was conducted at Agricultural and Natural Resource Research Station of Uremia. The experimental design was...
This experiment was conducted to evaluate the effect of deficit irrigation on seed yield and its components of sunflower hybrids, and also identify tolerant hybrids. Twelve sunflower hybrids; Farrokh, Shams, Ghasem, Barzegar, G5 ×43, G6×43, Hysun25, Hysun36, Azargol, Sumbro, Euroflor and Sirena were evaluated under three irrigation treatments; normal irrigation (60 mm), mild drought stress (1...
BACKGROUND AND PURPOSE The jumping distance (JD) is the degree of lateral translation of the femoral head center required before dislocation occurs. The smaller the distance, the higher the theoretical risk of dislocation. The aim of our study was to evaluate this jumping distance and its variation according to the characteristics of the implant, and also the theoretical gain in using large hea...
Operative treatment of displaced and comminuted radial head fractures involves internal fixation with plates and screws in cases where reconstruction is possible and replacement with a radial head prosthesis when comminution renders the radial head unreconstructable. The purposes of this study were to evaluate the morphometry of the radial head using a modern technique and to compare the findin...
One of the effective indirect selections methods for improving grain yield and its components is the selection index. In order to develop a suitable selection index for simultaneously increasing yield and its related traits, 100 sunflower inbred lines from different geographical origins were evaluated in randomized complete block designs with three replications at Urmia University in 2015 ...
