Research was conducted at Colby and Tribune, KS, from 2018–2020 to evaluate irrigation strategies, hybrid maturity, seeding rate on corn production. Irrigation strategies were a combination of frequency/timing (weekly or bi-weekly) applied pre- post-silking, amounts (1 1.5 inch/week). Hybrid maturities 108- 111-day hybrids planted 25,000 30,000 seeds/a. Average ranged 7.33 12.50 in. 8.41 13.44 ...
The potato psyllid, Bactericera (= Paratrioza) cockerelli (Šulc) (Hemiptera: Triozidae), is a major pest of potato. Studies were conducted to determine the age at which both males and females reach reproductive maturity and the effect of age and time of day on sex attraction. Adult B. cockerelli reach reproductive maturity within 48 h post-eclosion, with females being mature on the day of eclos...
Background: Little is known about Giberellic acid, a plant growth regulator used in many countries, on sperm parameters; so this study was conducted to evaluate its effects on sperm parameters. Materials and Methods: A number of twenty seven adult rats were divided into three groups (n=9): control group (C), control-sham group (C-Sh) and treatment group (Tr). The C-Shgroupand the Tr group were ...
sowing date and irrigation are two constrain factors for maize production. these factors can be simulated by using ceres-maize model. for this purpose two experiments (each one at two years) were carried out at agricultural research station of gorgan which is golestan province capital. the model was calibrated using three treatments of optimum irrigation and without stress in 2012 and two treat...
water scarcity is a major factor for limiting crop growth and development in arid and semi-arid regions. in order to study the effects of varying timing and severity of water deficit on mung bean phenological traits, a field experiment was carried out during 2009 growing season at agricultural research institute of zabol university. the experiment was laid out in split plot by using a randomize...
Understanding the impact of the warming trend on phenological stages and phases of cotton (Gossypium hirsutum L.) in central and lower Punjab, Pakistan, may assist in optimizing crop management practices to enhance production. This study determined the influence of the thermal trend on cotton phenology from 1980-2015 in 15 selected locations. The results demonstrated that observed phenological ...
