The efficacy of some potent low-dose herbicides of sulfonylurea group in conjunction with other traditional recommended herbicides for control of wide-spectrum of weed flora in transplanted rice (Oryza sativa L.) field was studied during the wet season of 2004 and 2005 at Cuttack, under rainfed shallow lowland. The major weeds found were Echinochloa spp., Cyperus iria, Fimbristylis miliacea, Sphenochlea zeylanica, Ludwigia parviflora and Aeschynomene indica. Triasulfuron + Pretilachlor (9 + 500 glha) applied 7 days after transplanting was found most effective in controlling weeds and maximizin

Information on the effects of multiple weed management tactics in corn is needed to develop integrated weed management systems. The effectiveness and compatibility of an in-row cultivator as compared to a standard interrow cultivator used with reduced rates of a soil-applied herbicide, rotary hoeing, and/or a bioeconomic model for POST herbicide selection was examined. Weed control with a single rotary hoeing at corn emergence controlled annual weeds similarly to two rotary hoeings.

Abstract:

Weeds are the most important biotic constraints to maize production. Yield losses in maize due to weeds depend on several factors such as weed emergence time, weed density and type of weeds. If the weeds left uncontrolled, it results in 100% yield loss. Since, labour availability to manual weeding and higher wages, it is necessary to have the strategy of chemical control of weeds in appropriate time to attain target yield and economic benefit. In this view, field experiments were conducted at Maize Research Station, Vagarai, Tamil Nadu (India) during the season kharif of the years 2015, 2016 a

Abstract The aryloxyphenoxypropionate (APP) herbicides are graminicides with excellent control of many grass weed species, including weedy rice (Oryza sativa L.). These herbicides block fatty acid biosynthesis by inhibition of the enzyme acetyl-CoA carboxylase (ACCase) and cause death of the plant. Through induced mutation of rice seeds with gamma-rays, rice lines resistant to APP have been developed. Plant dose-response assays confirmed resistance to the APP herbicides quizalofop-p-ethyl and haloxyfop-p-methyl. The carboxyl-transferase (CT) domain fragments of ACCase from the resistant line a

AbstractIn contrast to most autotrophic plants, which produce carbohydrates from carbon dioxide using photosynthesis, parasitic weed plants rely on host plants to form vascular connections through which they withdraw the required nutritive resources and water. Many important crop plants are infested by these heterotrophic plants leading to tremendous yield losses and rendering agricultural lands uncultivable. The parasitic weeds are physically attached to the host plants and therefore their control is challenging due to the lack of selective methods for killing the weeds without damaging the h

Review question / Objective: The objective of this review is to analyze the effect of zero-tillage and organic mulching (with emphasis on rice-straw) on several Key Performance Indicators (KPIs) related to productivity, resources-use efficiency, and soil health, as well as, C footprint, and weed control for growing potatoes in rice-based systems in Asia. Can zero-tillage and organic mulching increase agronomic gain in potatoes crop in Asia? Rationale: Potato cultivation under zero-tillage and mulching (PZTM) between rice or rice-other crops projects a sustainable intensification of rice-based

Abstract:

Feed inputs represent the largest variable cost of producing meat and milk from ruminant animals. Thus, strategies that improve the efficiency of feed utilization are needed to improve the global competitiveness of Israeli and U.S. cattle industries, and mitigate their environmental impact through reductions in nutrient excretions and greenhouse gas emissions. Implementation of innovative technologies that will enhance genetic merit for feed efficiency is arguably one of the most cost-effective strategies to meet future demands for animal-protein foods in an environmentally sustainable manner.

Abstract:

Accurate control of preheat is often required during pipeline welding, both for new construction and for in-service welding (repairs and hot tapping). Conventional methods of applying preheat, such as gas torches, are difficult to control, and can be slow and inefficient. Additionally, the rapid cooling associated with in-service pipelines tends to limit the effectiveness of any form of preheat. New equipment for induction preheating offers the possibility of achieving excellent levels of control together with high thermal efficiency, rapid response, and minimal disruption of accessibility to

Abstract:

The research on thermotolerance acquisition in broiler chickens by temperature conditioning early in life was focused on the following objectives: a. To determine the optimal timing and temperature for inducing the thermotolerance, conditioning processes and to define its duration during the first week of life in the broiler chick. b. To investigate the response of skeletal muscle tissue and the gastrointestinal tract to thermal conditioning. This objective was added during the research, to understand the mechanisms related to compensatory growth. c. To evaluate the effect of early thermo cond

Abstract:

The specific objectives of this research were the study of the physical and nutritional properties of the In Ovo Feeding (IOF) solution (i.e. theosmostic properties and the carbohydrate: protein ratio composition). Then, using the optimal solution for determining its effect on hatchability, early nutritional status and intestinal development of broilers and turkey during the last quarter of incubation through to 7 days post-hatch (i.e. pre-post hatch period) by using molecular, biochemical and histological tools. The objective for the last research phase was the determination of the effect of
