Abstract:

In two experiments conducted in the field between 1983 and 1985, timothy was established with or without barley, red clover, grassy weeds and broadleaf weeds. The plots were sampled during establishment and production years. At each sampling, the botanical composition was evaluated to characterize the weed populations. Throughout establishment, the weed populations were dominated by annual broadleaf and grassy weeds which, when growing separately, produced comparable amounts of biomass. However, when growing together, the grassy weeds were clearly dominated by the broadleaf weeds. During the s

Abstract:

Weed management strategies can influence insect infestations in field crops, yet no attempts have been made previously to manipulate weed populations in canola for integrated weed and insect management. Field studies were conducted during 2003 to 2005 at Lacombe and Beaverlodge, Alberta, Canada to manipulate weed and root maggot, Delia spp. (Diptera: Anthomyiidae), interactions in canola. Densities of monocot weeds were varied by altering herbicide applications, with rates ranging from 0 to 100% of the rate recommended. Weed populations declined, and yields were variable with increased herbici

Abstract:

A field experiment was conducted at Instructional farm, RCA, MPUAT, Udaipur during Rabi 2016-17 and 2017-18 to study the weed dynamics, yield and nutrient uptake in fenugreek. Weed management experiment consists of thirteen different weed management practices assigned to main plot and levels of vermicompost in sub plot. Results of the field experiment revealed that pre-emergence application of oxadiargyl 100 g/ha fb hoeing at 40 DAS recorded the lowest weed density (24.25 /m2) and dry matter of total weeds (158.22 g/m2) over weedy check (245.42 /m2 and 893.44 g/m2) and higher weed control effi

Abstract:

The species composition and density of weed seed in the soil vary greatly and are closely linked to the cropping history of the land. Altering tillage practices changes weed seed depth in the soil, which plays a role in weed species shifts and affects efficacy of control practices. Crop rotation and weed control practices also affect the weed seedbank. Information on the influence of cropping practices on the weed seedbank should be a useful tool for integrated weed management. Decision aid models use information on the weed seedbank to estimate weed populations, crop yield loss, and recommend

Abstract:

For this presentation we would like to discuss some history of weeds and their control, the evolution of weed science, the development of herbicides and the changing dynamics of weed science research. As mentioned by previous speakers, weeds cause great loss to almost every crop production enterprise in the United States and around the world. Man has sought to control weeds by various methods including cultural practices, cultivation, hoeing, and with herbicides. Pioneer weed scientists were individuals trained in the areas of physiology, botany, and agronomy. They applied their knowledge and

Abstract:

The popularity of growers using only postemergence (POST) herbicides for weed management in soybean was enabled by the commercialization of glyphosate-resistant soybean. The efficacy and flexibility provided by this technology diminished the use of soil residual herbicides and arguably, increased soybean yield loss from early-season weed competition. While, the rapid evolution and biogeographical spread of herbicide-resistant weeds, especially glyphosate-resistant biotypes, has renewed interest into the use of soil residual products, herbicide-resistant soybean technologies continue to be deve

With a growing concern about sustainability of agricultural production systems, interest in integrated weed management systems has increased. Increasing the understanding of weed seedbank dynamics will improve efficiency of management. The objectives of this study were to 1) quantify weed seedbank dynamics in response to seed density and burial depth, 2) determine weed seedbank decay at varying seed densities and burial depths, 3) quantify weed seed predation in wheat and tilled fallow fields, and 4) characterize and compare weed seedbanks in organic and conventional no-tillage production fiel

Abstract:

Over the last three decades, concern about food safety and the management of natural resources has increased. Instigated by the previous EU pesticide review, (EU 91/414) carrot growers in particular have been hit by the revocation of several post-emergence herbicides. There is real concern among growers that this may impair profits. To identify alternative weed control strategies, a modelling framework capable of simulating the impact of alternative weed management strategies on long-term weed population dynamics, was proposed. Scentless mayweed (Tripleurospermum inodorum) was chosen as model

Abstract:

The increasing attention of public opinion towards the environmental impact of production activities has made it imperative to reduce the aggressiveness of productive systems on the environment. Also the agricultural sector, considered one of the principal strengths of transformation of the territory, is asked to predispose eco-compatible programmes of production. The institutions and national and international organisms encourage the adoption of techniques of conservative agriculture as a tool for guaranteeing, on the one hand the necessary crop production to face the demand for food of the g

Here we analyse the potential contributions of CA towards adaptation to the effects of climate change by summarizing data on infiltration, soil moisture dynamics and crop productivity under heat and drough

Abstract:

The roughness of a ship�s hull can have a significant impact on the environment, primarily through its effect on the ship�s fuel consumption and, consequently, carbon emissions. The resistance a ship encounters as it moves through the water can be broadly categorized into two main types: frictional resistance and wave-making resistance. Hull roughness increases frictional resistance, also known as skin friction resistance. This resistence component is a major aspect of the total resistance of a merchant ship, leading to increased power and fuel consumption. The present study aims to systematic

Abstract:

Background PHS (pulmonary hypertension syndrome, ascites syndrome) is a serious cause of loss in the broiler industry, and is a prime example of an undesirable side effect of successful genetic development that may be deleteriously manifested by factors in the environment of growing broilers. Basically, continuous and pinpointed selection for rapid growth in broilers has led to higher oxygen demand and consequently to more frequent manifestation of an inherent potential cardiopulmonary incapability to sufficiently oxygenate the arterial blood. The multifaceted causes and modifiers of PHS make

Abstract:

The National Park Service (NPS) Natural Resource Condition Assessment (NRCA) Program administered by the NPS Water Resources Division evaluates current conditions for important natural resources and resource indicators using primarily existing information and data. NRCAs also report on trends in resource condition, when possible, identify critical data gaps, and characterize a general level of confidence for study findings. This NRCA complements previous scientific endeavors, is multi-disciplinary in scope, employs a hierarchical indicator framework, identifies and develops reference condition

Abstract:

To study the tensile behavior of T-stubs with various design parameters under different loading scenarios, uniaxial static and dynamic tensile tests were carried out. The effects of flange thickness, bolt preload, bolt strength and loading conditions were discussed. The failure modes observed under different conditions were presented. Besides, the load-displacement response was analyzed in detail. The experimental results showed that the bolt preload only affected the initial stiffness of the specimens, and smaller flange thickness and lower bolt strength would result in unfavorable performanc
