milk thistle is used traditionally as a hepaprotective agent and supportive treatment of liver disorders. the most problems in milk thistle harvest are tall height, seed shedding and being spinous. in this trial, effects of 3 native populations (p1: isfahan violet flower, p 2: ahvaz white flower and p3: ahvaz violet flower) and 3 topping levels (t1:control, t2: topping in 7 leaves stage and t3:...

one of the most important practices in flue-cured tobacco farming is topping and sucker control at the right time. topping cause's development and root growth, drought tolerance, reduce deployment pests, increased synthesis of nicotine. this study was conducted in randomized complete block design (rcbd) with 10 treatments in 3 replications over two years (2008-2009) at tirtash research and educ...

Production costs could be substantially reduced if the height of fruit trees could be lowered enough to eliminate the need for, or reliance upon, ladders in the orchard. Recent research demonstrates that high yields can be obtained on shorter trees with appropriate management techniques, but vigor control can be a problem. In 2004, selected rows of ‘Arctic Star’ nectarine trees growing in the D...

Manual removal of the main stem tips cotton (Gossypium hirsutum L.) is a traditional topping approach in China. However, chemical has become an inevitable trend. Therefore, it great significance to study effect and appropriate concentration agents for advancement whole process mechanization management technology. A two-year field experiment was conducted evaluate effects different methods on yi...

The potential for improved performance of wave rotor cycles through the use of passage height variation is examined. A Quasi-one-dimensional CFD code with experimentally validated loss models is used to determine the flowfield in the wave rotor passages. Results indicate that a carefully chosen passage height profile can produce substantial performance gains. Numerical performance data are pres...

Removal of terminal buds (topping) and control of the formation of axillary shoots (suckers) are common agronomic practices that significantly impact the yield and quality of various crop plants. Application of chemicals (suckercides) to plants following topping is an effective method for sucker control. However, our current knowledge of the influence of topping, and subsequent suckercide appli...

A field experiment was conducted at the experimental of Department Horticulture in Sylhet Agricultural University to evaluate growth and yield performance three okra genotypes (viz. BARI Dherosh-1, Dherosh-2 & RAJ F1) under special management practices de-topping non de-topping) from March July 2022. The two factor laid out a Randomized Complete Block Design (RCBD) with replications. Dheros...

For the testing of the effect on the tsunami prevention facilities, a simplified method for tsunami risk assessment was suggested without wave run-up analysis. This method is proposed using calculated offshore tsunami waveform and field reconnaissance such as the seawall height, time necessary for residents’ evacuation and tsunami warning insurance. Then, two normalized values are evaluated; on...

Topping stage of tobacco is a key time for development of agriculture measures to promote the quality of leaves. In order to investigating influence of topping timing and suckericide content on tobacco leaf, a factorial experiment on the basis of RCB design with 3 replications was conducted in 2011 at the Tobacco Research Farm of Isfahan. Treatments were including topping time (T1: t...
