Abstract Auxinic herbicides have been commonly used in production systems for broadleaf weed control many years. One potential negative aspect to their use is propensity volatilize and move away from the treated area after application. This research examined three herbicide formulations relative amounts of vaporization following application under field conditions Knoxville, TN, 2017, 2018, 2019...

-the cowpea aphid, aphis craccivora koch, is an important pest of robinia pseudoacacia frisia. life table parameters of a. craccivora were determined under natural (16- 33ºc and 32-89% rh, respectively) and laboratory (25 ± 1ºc, rh of 70 ± 5% and a photoperiod of 16:8 h (l: d) conditions. the data were analyzed using the age-stage, two-sex life table theory. each experiment was replicated 45 ti...

in order to deliberate correlation coefficient between grain yield and yield components among 31 cowpea genotypes under normal irrigation (non-stress) and drought stress (water withholidng after flowering stage until maturity) an experiment was performed in a randomized complete block design (rcbd) with three replications at research field of university of tehran located at karaj during 2011-20...

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...

in order to evaluate the utilization ability of drought resistance indices such as: yield index (yi), yield stability index (ysi), stress susceptibility index (ssi), tolerance (tol), mean productivity (mp), geometric mean productivity (gmp) and stress tolerance index (sti) in sunflower hybrids, three separate experiments were conducted as randomized complete block design at the research field o...

development of new cultivars with high grain yield (gy) stability and good adaptability under both terminal drought stress (tds) and normal irrigation conditions, which plays important role in production of wheat, is one of the major goals of wheat breeding program for cold dry areas of iran. the objective of this investigation was to study the stability and adaptability of gy and genotype × lo...

a field experiment was carried out during 2001 in the experimental fields of sugar beet seed institute in karaj. the objective of this study was to determine the response of some quantitative and qualitative traits of three sugar beet lines subjected to continuous water stress and normal conditions. three sugar beet lines 7219-p.69, bp-karaj and 7112 as tolerant, semi tolerant and sensitive to ...

the experiment was aimed at investigating the effects of defoliation (i. e. amanipulation of source size) at different times and with different intensities on yield, grain protein content and remobilization of dry matter from shoot to grain under various levels of soil moisture and nitrogen in winter wheat. two separate field experiments were conducted simultaneously under water stress vs irrig...
