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...

Winter pruning has been a common practice in peach. Twig topping associated with it, but this used at the same intensity, regardless of cultivar. Therefore, study aimed evaluating productive behavior and quality ‘Maciel’ peach grafted on ‘Capdeboscq’ ‘Okinawa’ (P. persica) as rootstocks, when they were submitted to different twig intensities winter pruning. The following three evaluated: short ...

In Portugal., the study of mechanical pruning in olive orchards began 1997. Trials were carried out traditional orchards, and obtained results revealed that can contribute to reduction costs without a yield. 2005, authors started an evaluation high-density orchards. The trial was organised randomised, complete block design, with three replications. Four treatments compared: T1—manual pruning, u...

Pruning is one of the most expensive tasks in citrus production, and its mechanization could increase productivity competitiveness farms. The effect mechanical pruning on yield depends variety, crop condition, location; among other factors. ‘Clemenules’ mandarin variety important ones; therefore, aim this work was to study effects twelve strategies over four years, conduct an economic analysis....

Due to the extensive tree canopy, traditional method of cultivation has had difficulty achieving intended levels productivity. As a result, it became necessary enhance current manufacturing system in addition impressing with its There is tendency for fruit trees be planted more densely or meadow orchards control size, keep desired architecture, and make operations like pruning, pest control, ha...

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...

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...

The process of topping elicits many responses in the tobacco plant, including an increase in nicotine biosynthesis, and the secondary growth of roots. Some topping responsive miRNAs and genes have been identified in our previous study, but the mechanism of the tobacco response to topping has not yet been fully elucidated. In this study, topping responsive proteins isolated from tobacco roots we...
