BACKGROUND: Barley is one of the main important crops in the world, mainly used for animal feed and malt. OBJECTIVES: This study was conducted to evaluate the comparisons of seed yield and its components, phenological and physiological traits of different barley cultivars under Lorestan environmental condition. METHODS: Current rese...

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...

this study evaluated direct drilling planters used for wheat cultivation in khorasan-e razavi province. a randomized complete block design with three replications was used. the treatments were direct drilling of wheat plants into wheat residue using the following direct planters: (1) sfoggia (13-25), (2) baldan (spd3000), (3) tondar (spd 2500), (4) semeato (shm 11/13). the parameters measured w...

introduction cultivated sunflower is one of the largest oilseed crops in the world. sunflower seed is the third largest source of vegetable oil worldwide, following soybean and canola. nitrogen is one of the most important elements for crops to achieve optimum yields and quality. phosphorus (p), next to nitrogen, is often the most limiting nutrient for crop and forage production. phosphorus ava...

to study the effects of planting date and planting density on quantitative traits of medicinal plant, schneider squash (cucurbita pepo l.), an experiment was conducted at research field of ferdowsi university of mashhad, in year 2012. a split plot arrangement based on randomized complete block design with three replications was used. treatments consisted of three planting date levels (1 may, 11...

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...

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 ...

sunflower (helianthus annus l.) is the most important between oil plants in iran. the objective of this study was to evaluate the effects of micronutrients application on the sunflower yield under drought stress. this experiment was carried out at golmakan agriculture research station (iran) in 2005 that using a split plot randomized complete block design with four replications. irrigation was ...
