due to limited water resources, applying efficient water use in agriculture is very important. this experiment was carried out in kabootarabad agricultural research station for two years using split plots in a randomized complete block design with four replications. six irrigation treatments based on evaporation from class a pan were applied as the main factor at three cotton growing stages, na...

This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...

Identification of the last effective boll population allows informed decisions for termination of insecticide and application of harvest aids. However, the current COTMAN cutout reference, i.e., NAWF=5 (Oosterhuis et al., 1999), may need to be changed for ultra-narrow-row (UNR) cotton. This study is part of a multi-state project which has an overall objective of determining the main-stem node n...

to determine the best planting date and irrigation schedule in a cotton field (gossypium hirsutum var.varamin) in garmsar region an experiment was conducted in 2011. the experimental design was splitplot based on randomized complete block with three replications. three irrigation termination dates (2011sep 11th, 2011 sep 21st and 2011 oct 2nd) arranged in main plots as main factor and three pla...

Identification of the last effective boll population allows informed decisions for termination of insecticide and application of harvest aids. However, the current COTMAN cutout reference (i.e., NAWF=5) indicates physiological cutout (Oosterhuis et al., 1999) may need to be changed for ultra-narrow-row (UNR) cotton. This study is part of a multi-state project the overall objective of which is t...

Cotton is under the constant threat of leaf curl virus, which is a major constraint for successful production of cotton in the Pakistan. A total of 3338 cotton genotypes belonging to different research stations were screened, but none were found to be resistant against the Burewala strain of cotton leaf curl virus (CLCuV). We explored the possibility of transferring virus-resistant genes f...

in order to determine the best time of cotton irrigation in east of mazandaran province, an experiment, conducted for 3 successive years in agricultural research station of baykola. six treatments and four replications were carried out with randomized complete block designs for sahel variety. water treatments were carried out based on, i0: no irrigation, i1: once irrigation in boll opening stag...
