Abstract:

The effects of factors (branch diameter, number of branches, plantation age number of prunings, working assembly of pruning devices, etc) on the duration of pruning in poplar plantations were investigated. Poplar branches were pruned by mechanized devices Stihl HT 75 and Husqvarna 250 PS. It was concluded that pruning time increases significantly with the number of removed branches in all plantations disregarding the plantation age and spacing. This correlation is represented by a degree function. Also, pruning time increases with the size of average branch diameter removed from the tree. The

Abstract:

One of the most crucial operations in tea cultivation is pruning, in which the branches of the tea bushes are slash down at a predetermined height to reinvigorate the bush and bring it within the pluckers range. Pruning also helps to maximize the yield and quality. Among the pruning operations practiced, Light Pruning (LP) is one of the drastic and vital operations that has significant impact on tea production and quality. Recovery potential of a tea plant after pruning depends on many factors among which time of pruning plays an important role because of the surrounding environmental conditio

The pruning and the assessment of time needed for pruning bearing trees was done in early spring each year during the given period. The results indicate that the labour intensity, i.e. time required to prune the tree depends on variety/rootstock combination.

Root pruning reduced terminal shoot growth by ≈30% in 1985-89 with no influence in 1990. Cumulative yield was reduced by root pruning at bloom (14%) or mid-June (20%), and cumulative yield efficiency [kg·cm-2 trunk cross-sectional area) was reduced by root pruning with no difference among pruning times except in 1 year, where abundant moisture throughout the season appeared to negate the effect.

Pruning is an unavoidable necessity of virtually all arboreal fruit crops. In the tropics and subtropics, pruning of mango (Mangifera indica L.) is particularly important due to its tendency for frequent flushes, especially in humid tropics. Commercial orchards must maintain control of both tree size and orchard productivity in order to remain productive. Tip, formation, and severe pruning can be used in a variety of circumstances to produce predictable and useful results for a variety of purposes. For example, tip pruning can be used to encourage frequent flushing and branching of young trees

Tree vigour, yields and mean fruit weight were evaluated in this study in relation to the term of the pruning. The subject of this paper is the experimental orchard in the stage of full productivity and the study is a continuation of a previous publication focussed on its performance till 2005. The vigour of Kordia cv. trees on both rootstocks pruned in August was distinctly

Abstract Tree production requires time for pruning to meet customer expectations, yet pruning can slow growth and increase the time (and cost) to prepare trees for market. Our research quantifies trade-offs between growth and pruning. In two separate locations, over two time periods, we found no difference in caliper growth between trees with only the largest one or two low branches removed at each pruning, compared with trees having all lower branches shortened.

Abstract:

A novel scheme to compute energy on-the-fly and thereby control the quality of the image frames dynamically is presented along with its FPGA implementation. This scheme is suitable for incorporation in image compression systems such as video encoders. In this new scheme, processing is automatically stopped when the desired quality is achieved for the image being processed by using a concept called pruning. Pruning also increases the processing speed by a factor of more than two when compared to the conventional method of processing without pruning. An MPEG-2 encoder implemented using this sche

Abstract:

Among various network compression methods, network pruning has developed rapidly due to its superior compression performance. However, the trivial pruning threshold limits the compression performance of pruning. Most conventional pruning threshold methods are based on well-known hard or soft techniques that rely on time-consuming handcrafted tests or domain experience. To mitigate these issues, we propose a simple yet effective general pruning threshold method from an optimization point of view. Specifically, the pruning threshold problem is formulated as a constrained optimization program tha

Pruning treatments began in Winter 2017–18 (before year 3) and continued each year through 2020–21 (year 6). Treatments included 1) recommended pruning for ‘Legacy’, removing less wood and leaving more short, thin laterals and a denser bush than is typical for most norther

Abstract:

Elimination of rainy-season crops is pivotal to encourage winter crops in guava. In general, rainy-season guava fruits are of poor fruit quality, insipid in taste, have poor shelf life, and mostly affected by many insect pests. Pruning is also considered one of the most eco-friendly methods for crop regulation. To fully comprehend the impact of pruning time and severity on flowering, fruit quality, and crop production, a field experiment was carried out. Three alternative pruning times (mid-April, mid-May, and mid-June) at different pruning levels (low, moderate and heavy pruning) were employe

Weekly pruning treatments combined with hydrogen cyanamide applications from early May to late June in 1987 and 1988 were evaluated for their ability to advance budburst, flowering, colouring and maturity of Cardinal grapes grown in unvented, unheated vegetable glasshouses. The glasshouse provides protection from frost, hail, wind and birds, and permits production of unblemished fruit. Hydrogen cyanamide-treated vines reached maturity approximately 1 month earlier (P<0.05) than untreated vines pruned on the same day. Budburst occurred 28-61 days after pruning with application of hydrogen cy

In this paper, the hypothesis that the pruning proportion is positively correlated with the compression scale of the model but not with the prediction accuracy and calculation time is put forward. For testing the hypothesis, a group of experiments are designed, and MNIST is used as the data set to train a neural network model based on TensorFlow.

Pattern search is an important class of queries for time series data. Time series patterns often match variable-length segments with a large search space, thereby posing a significant performance challenge. The existing pattern search systems, for example, SQL query engines supporting MATCH_RECOGNIZE, are ineffective in pruning the large search space of variable-length segments. In many cases, the issue is due to the use of a restrictive query language modeled on time series points and a computational model that limits search space pruning.
