Guidelines for physical weed control research: flame weeding, weed harrowing and intra-row cultivation [PDF]
, 2004 A prerequisite for good research is the use of appropriate methodology. In order to aggregate sound research methodology, this paper presents some tentative guidelines for physical weed control research in general, and flame weeding, weed harrowing and ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Water is a fundamental necessity for our existence, but its rapid contamination is causing devastating effects on the environment and health of living species worldwide. Adsorptive removal of pollutants is one of the popular water treatment techniques because of its simplicity, affordability, and the broad range of available adsorbents.

Sowing time, false seedbed, row distance and mechanical weed control in organic winter wheat. [PDF]
, 2000 In organic farming, mechanical weed control in winter wheat is often difficult to carry out in the fall, and may damage the crop, and weed harrowing in the spring is not effective against erect, tap-rooted weeds such as Tripleurospermum inodorum, Papaver

Applications in Plant Sciences, EarlyView.Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

Evaluation of mechanical weed management techniques on weed and crop populations
New Zealand Plant Protection, 2001 One of the main barriers for conventional farmers converting to organic production is weed control An experiment was set up to evaluate the efficacy of three mechanical weed control methods tine weeder spoon weeder and interrow hoe (only in the beans (Phaseolus vulgaris)) in four organically grown crops In borage (Borago officinalis) weed dry matter ...

Adaptive Genomic Divergence Across Altitudes in Capsella bursa‐pastoris
Biological Diversity, EarlyView.Genomic divergence was observed between high‐altitude and low‐altitude populations of Capsella bursa‐pastoris in China, consistent with an important role of ecological factors. Candidate adaptive loci associated with enhanced energy metabolism, photoprotection, and growth plasticity under altitudinal stress were identified.

Analysis and Definition of the close-to-crop Area in Relation to Robotic Weeding [PDF]
, 2004 The objective of this paper is to analyse and define the field conditions close to the crop plants of sugar beet (Beta vulgaris L.). The aim is to use this study for the choice and development of new physical weeding methods to target weeds at individual
