there are varying patterns for growing different varieties of branched or non-branched sesame. this experiment was conducted during a two-year period (2000-2001) to identify the optimal practice for cultivation of the uni-branched sesame in the safi-abad agricultural research center, khuzestan province. the statistical design was set up as strip-plot in a randomized complete block with four rep...

background and objectives: drought is one of the most important factor limiting plant growth around the world and the most common environmental stress which is limited produce approximately 25% of the world's land. production of secondary metabolites in medicinal plants changes by environmental condition and also water stress is effective factor in growth and synthesis natural compounds in...

in order to examine the effects of biological and chemical fertilizers with the use of salicylic acid on the agronomic characteristics of corn as a factorial experiment in randomized complete block design with three replications at the agricultural research station in 2011 was boroujerd. factors examined included three levels of phosphorus fertilizer (0, 100 and 150 kg ha), two levels of biolog...

in order to study the effect of planting date on duration of phenological periods in wheat cultivars, a randomized compelet block design experiment with four replications was conducted in gorgan university of agricultural science and natural resources research station. the factors were eight sowing dates (14 december, 20 january, 18 february, 20 march, 16 april, 21 may, 30 july and 6 august) an...

. in order to study the variation for seed yield and its components, 200 accessions of alfalfa (medicago sativa l.) were sown as drilled plots, using alpha designs/unreplicated with two repeated entries with in all of 10 blocks under dry land farming system in kabodarahang research station, hamadan, iran, during 2010 to 2011. data were analyzed for descriptive statistics, correlation, regressio...

Plant growth regulators (PGRs) are commonly used in commercial farming to control lodging in cereals. PGRs have been shown to alter yield formation and plant stand structure, other than the straw length. To study their potential in Northern growing conditions PGRs and their application time impacts on plant stand structure and yield formation in tall and short statured cultivars of barley, oat,...

objective: evaluation activity was conducted using three spearmint genotypes (wg-spm-engl, spm-fran and spm-eas) and one standard check (wgsm-03) at wondo genet, awassa, debre zeit and allagae during 2012 and 2013 for two years. methods: the treatments were arranged in randomized complete block design with four replications. data on leaf to stem ratio, leaf yield/ha, essential oil content and e...
