The growth and tuberization of potatoes (Solanum tuberosum L.) maintained for 6 weeks under four different regimes of continuous irradiance were compared to plants given 12 hours light and 12 hours dark. Treatments included: (a) continuous photosynthetic photon flux of 200 micromoles per square meter per second cool-white fluorescent (CWF); (b) continuous 400 micromoles per square meter per s...

in order to evaluate the effects of drought stress and plant density on yield, yield components and morphological characters of pinto bean (phaseolus vulgaris l.) c.o.s16 cultivar, a field experiment was conducted in split plot arrangement based on a randomized complete block design with three replications in research field of yasouj university during 2010. experimental treatments were pinto be...

Genetic improvement of grain yield is always an important objective in wheat breeding. Here, a genome-wide association study was conducted to parse the complex genetic composition of yield-related traits of 105 elite wheat varieties (lines) using the Wheat 90K Illumina iSelect SNP array. Nine yield-related traits, including maximum number of shoots per square meter (MSN), effective number of sp...

to evaluate the effect of zn sulfate foliar application on morphologic and quantitative characteristics of safflower (carthamus tinctorius l.) cultivars, a field experiment carried out in ramin agriculture and natural resources university of khouzestan, iran, in a factorial arrangement in a randomized complete block design with four replications, during 2012-2013. treatments consisted of two sp...

in order to determine the appropriate plant density of spotted bean in yasouj, a field experiment was conducted in 2008 as a factorial in a randomized complete block design with three replications. three spotted bean cultivars (keshavarzi, talash and oshtori) were sown at five plant densities (10, 20, 30, 40 and 50 plant.m-2). results showed that effect of plant density, cultivar and interactio...

an experiment was conducted as a split – split plot in form of a randomized block design with four replications in cilakhor region of iran in 2004. the main factor was the seed planting date with three levels (5, 12 and 25 april), sub factor was the crop density with two levels (160,000 and 250,000 pl/ha) and sub-sub factor was the crop arrangement with two levels (equidistant and non-equidista...

in order to evaluation of seed production index in lambsquarters (chenopodium album), leaf appearance and yield of fennel (foeniculum vulgare) under inter-specific competition a factorial experiment was conducted in islamic azad university, tabriz branch, iran, during 2011-2012. treatments were weed densities of 0, 2, 4, 6 and 8 plants per meter row and its relative emergence times of simultane...

in order to study the effect of row spacing and plant density on quantity and quality yield of soybean in weed competitive condition, a field experiment was carried out at research farm of yasuj agricultural college in summer of 2011. experiment arrangement was split factorial base on randomized complete block design with three replication. the main factor included weed ( in two levels of contr...
