To evaluate the effect of seed pre-soaking on forage yield and quality and water productivity in late planting of two forage sorghum cultivars, a field experiment was conducted was conducted as split factorial arrangements in randomized complete block design with three replications in 2017 and 2018 growing seasons at the research field of Seed and Plant Improvement Institute, Karaj, Iran. Four ...
field experiments were conducted to investigate the effects of sowing dates and irrigation on seed quality of a spring-type safflower cultivar, in karaj-iran, during 2008 and 2009 growing seasons. a split plot design based on a randomized complete block layout with three replications was used in which sowing dates and irrigation treatments comprised the main plot and sub-plot, respectively. the...
To study the effects of planting date and density on yield and its components in chickpea (Cicer arietinum L.) genotypes under dryland conditions of Khorram-Abad, an experiment was conducted during 2005-2006 growing season at the Agricultural Research Station of Lorestan Weather Department. Three sowing dates (March 6, March 21, and April 5) and two chickpea genotypes (Greet and Flip 93-93) wit...

In this study, the an AMMI analysis (additive the main effects and the multiplicative interaction effects) was used to evaluate the yield stability of nine oats genotypes (4 Canadian cultivars and 5 Turkish breeding lines) and Makoi barley (as ckeck) in the 6 environments (3 dates of planting of Oct.12, Oct.31 and Nov.21 and 3 sowing densities of 300, 375 and 450 seeds/m2). The experiment was c...
in order to study the effects of sowing date and plant density on forage yield and some morphological characteristics of corn, an experiment was conducted in gorgon research station in 2008. in this experiment two sowing date (18 april and 21 june) and six plant densities (25000, 45000, 65000, 85000, 105000, and 125000 plant per hectare) were evaluated in form of factorial experiment (2×6) with...
to evaluate the effects of planting date and plant density on morphological characteristics, including essential oil content of ajowan (trachyspermum ammi) a study was conducted during the years 2003 and 2004 at the experimental farm, faculty of agriculture, ferdowsi university of mashhad. treatments were laid out in a factorial form based on a complete randomized block design of three replicat...
The effects of Chickpea (Cicer arietinum L.) varieties, and sowing dates on weed interference were investigated in a 2-year (2002-3, and 2003-4 growing season) field experiment in Agricultural Research Station of Kohdasht in Lorestan Province. The experimental design was a randomized complete block in factorial arrangement with 3 replications. The experiment had 3 factors: weed interference at ...
Many crops are grown in regions and sowing dates which the climate is not in the desirable condition, bringing about decreases in efficiency of agricultural inputs and crop yield. The spring safflower is planted under irrigation condition in Isfahan province and the temperature during growing season plays a major role in its seed yield. For thermal zoning of spring safflower planting in Isfah...
abstract in this study, impact of climate change on net irrigation requirement (in) and yield of wheat using cgcm3 climate projection model, one of the aogcm models, in behshahr area is evaluated. changes in temperature and precipitation were simulated run under the ipcc scenario a2 for 2011-2040, 2041-2070 and 2071-2100 periods. this work was done by using statistical and proportional downscal...
