in order to study the effects of different irrigation regimes and nitrogen fertilizer levels on yield and yield components of chickpea (ilc482), a field experiment involving chickpea genotype ilc482 was conducted as factorial arrangement based on a randomized complete block design with four replications in the agricultural research station, ferdowsi university of mashhad during growing season o...
Extended Abstract Introduction and Objective: Wheat is one of the most important crops in the world that plays a key role in ensuring food security. In wheat breeding programs, selection of genotypes with desirable agronomic traits and high yield potential have always been the goal of plant breeders. Increasing the selection efficiency for grain yield depends on genetic knowledge from morpholo...
to evaluate the anti-transpiration effect on yield and yield components of corn late yield 704 under drought stress experiment split factorial randomized complete block design with three replications in spring 2012 at the research station, kermanshah. and paclobutrazol treatments include salicylic acid, which is taking on two levels. based on the values determined in the following order foliar ...
A diallel analysis of eight bread wheat (Ttriticum aestivum L.) cultivars was conducted to determine genetic parameters and the type of genetic control for yield and yield components. The parents and their F1 hybrids were evaluated in a randomized complete block design with 3 replications. General and specific combining ability effects were estimated by the method 2 of the Griffings model I, an...
In order to study the effects of foliar application of phosphorus (P) and water deficit on yield and yield components of winter wheat (Triticum aestivum L., cv. Alvand), a split-plot experiment, with completely randomized blocks design and three replications, was carried out at the Research Farm of Boyer Ahmad Agricultural and Natural Resources Research Station, 13 km west of Yasouj, in 2008-20...

Abstract: Wheat grain yield is reduced by post-anthesis drought stress conditions in most wheat growing farmlands of Iran. To evaluate the effect of post-anthesis-withholding irrigation on yield, yield components and canopy temperature of wheat cultivars, a field experiment was conducted as split plot in a completely randomized block design with four replications at experimental farm of coll...
drought stress is one of the most important abiotic stresses which can affect the growth of a plant, thereby curbing crop yield. identification of effective morphological traits is the main aim of each breeding program. our objective was to identify agronomic traits associated with changes in grain yield of wheat under irrigated and drought conditions. to address this objective, grain yield and...
abstract to evaluate the effect of different levels of nitrogen fertilizer on competitive ability of canola against wild mustard interference, a split plot trial based on a randomized complete block design with 3 replications was carried out. experimental treatment were amounts of nitrogen fertilizer of urea (46% nitrogen) in 4 levels (100, 150, 200 and 250 kgn/ha) and 5 wild mustard densities ...
in order to investigate the effects of nitrogen application rates and different planting beds on yield and yield components of garlic (allium sativum l.), a field experiment was conducted as split plot based on a randomized complete block design with four replications at the agricultural research station, azad university of torbat-e-jam, iran, during 2009-2010. three nitrogen application rates ...
