There is concern that cotton gins may serve as loci for reintroduction of boll weevils, Anthonomus grandis grandis Boheman, to eradicated or suppressed zones when processing weevil-infested cotton from neighboring zones. Previous work has shown that virtually all weevils entering the gin in the seed cotton will be removed before they reach the gin stand. Those not killed by the seed cotton clea...
تأثیر آبیاری تکمیلی و تیمار پیش جوانهزنی بذر بر صفات کیفی، عملکرد علوفه تر و خشک ماشک رقم دیم مراغه
To evaluate the effect of supplemental irrigation and seed priming on yield and some quantity and quality characteristics of vetch (Vicia dasycarpa) rainfed maragheh cultivar, an experiment was carried out at the Research Farm of Faculty of Agriculture, University of Urmia, West Azarbaijan province, Iran, during 2011. The experiment was laid out using split-plot, based on Randomized Complete Bl...
A decline in growth, flowering, and boll (fruit) retention is referred to as cutout in cotton (Gossypium hirsutum L.). Fruit load affects cutout, possibly through hormonal effects. Experiments were conducted to test the hypothesis that fruits are a source of abscisic acid (ABA) that moves into fruiting branches and growing points where it inhibits growth, flowering, and boll retention. Removal ...
In order to study the effects of bio fertilizers application on quantitative and qualitative yield, proline content and activity of some antioxidant enzymes in sunflower (Helianthus annus L. var. Urofelor) in different irrigation withholding levels, a factorial experiment was conducted based on randomized complete block design with three replications in research farm of faculty of Agricultur...
The present study was conducted in order to investigate the effect of salicylic acid on growth, yield and macro-elements absorption of fennel in split-plot as base on randomized complete block design (RCBD) with three replications in Tehran, Iran. Irrigation regime as main plot was undergone in 5 levels that included: I1: full irrigation, I2: cut off irrigation at stem elo...
Drought is one of the most important stresses for crops that do not have same effects on growing stages. Recently, drought involved many various agriculture crops such as Date palm tree. This experiment carried out in a randomized complete blocks design with six treatments and five replications, in order to determine the critical and sensitive stages of date palm growth to water stress. The tre...
Peak bloom is one of the most recognizable periods in cotton development Fields may become blanketed with white blooms as boll loading accelerates to a maximum. This landmark developmental stage signals that a shift is occurring in the crop's biology and your management priorities. This newsletter will profile the crop at peak bloom and outline some management considerations that can affect per...
Photosynthesis and wheat grain yield responses to supplemental irrigation with different amount of applied water under dryland conditions were investigated. Therefore, a two-year field experiment was conducted research farm of College of Agriculture, Shiraz University during 2004-2005. Five levels of irrigation including dryland conditions, irrigation at stem elongation, booting, flowering an...
In order to investigate the effect of different irrigation regimes on some agronomic and physiological characters of three chickpea cultivars (Jam, 301 and Pirooz), a field experiment was conducted in 1998 at the Agricultural Research Farm of Tabriz University, Tabriz, Iran. A split plot experiment based on a randomized complete block design with three replications was used, in which irrigation...
