Conyza bonariensis (L.) Cronquist is a widespread noxious weed with high fecundity, associated no-till systems such as vineyards and other perennial crops in Mediterranean climates. Seeds germinate staggered flushes, which leads to great variation the growth stage between individuals same field, chemical control becomes challenging. Besides, species have evolved resistance herbicides worldwide,...

Due to the increasing number of herbicide-resistant weed populations and resulting yield losses, control must be given high priority ensure food security. Integrated management (IWM) strategies, including reduced herbicide application, sensor-guided mechanical combinations thereof are indispensable achieve this goal. Therefore, study examined pre- post-emergence applications with sensor-based h...

To reduce reliance on herbicides and maintain crop productivity, integrated weed management (IWM) seeks to optimize synergies between diverse sets of practices combined at the cropping system scale. Nevertheless, data community response long-term implementation IWM remain scare. Here, we assessed effects four systems with contrasting objectives (S2: transition from superficial tillage conservat...

The stakeholders’ involvement in any decision making process is a key point in the Integrated Water Management (IWM). A successful watershed management process has to be participatory, allowing the stakeholders working together to set criteria for sustainable management, to identify priorities and constraints, to evaluate possible solutions, to recommend technologies and policies, and, finally,...

Weed infestation is considered a significant yield reducing factor in maize around the world as well south Asia. Integrated weed management (IWM) recommended to reduce our reliance on synthetic herbicides and sustainable production. In this study, different tillage regimes various allelopathic treatments were integrated for spring planted at Agricultural Research Station, Swabi (KP), Pakistan d...

Infectious video watermarking (IVW) is to embed the first watermark in encoder/decoder for the protection of video contents and to infect the watermark in different codecs whenever video contents are copied or edited. This paper presents an infectious reversible video watermarking for fast infection in the infectious watermarking model (IWM). Our method is designed by following main features. T...

The emergence of integrated watershed management (IWM) in several countries throughout the world reflects a growing recognition of the multiple—often competing—uses of water, and the increased awareness of the interrelationships of water systems with other physical and socioeconomic systems. There are many different definitions and descriptions of the concept. Margerum and Born (1995, 377) cont...
