Research ArticleOpen accessEvery word in the titleEvaluation of the Use of Rice Bran Compost for Eco-friendly Weed Control in Organic Farming SystemsM.A.I. Khan, K. Ueno, S. Horimoto et al.Rice bran compost (RC) was evaluated under greenhouse and field conditions for eco-friendly weed control of vegetable crops in organic farming systems. RC was applied 7 days before spinach seed sowing, at the rate of 0% (control), 10%, 20% and 30% of soil (v/v) in the greenhouse and 2 kg m-2 under field conditions. RC significantly controlled the number and … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,930 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEvaluation of the Upland Weed Control Potentiality of Green Tea Waste-Rice Bran Compost and Its Effect on Spinach GrowthM.A.I. Khan, K. Ueno, S. Horimoto et al.This study evaluated the upland weed control potentiality, germination inhibition ability and growth suppression efficiency of the five combinations of green tea waste - rice bran compost (GRC). GRC was prepared by mixing green tea waste and rice bran at five ratios, and allowed to decompose for 5 mo. Application of GRC suppressed weed growth up to 93.4% in number … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 8,207 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleDiversity and Allelopathic Potential of Weeds among Panamanian Coffee CropsLilia Cherigo, Jorge Lezcano, Sergio Martínez-LuisWorldwide, coffee is one of the most highly consumed and produced crops. Coffee production is a significant activity in the Panamanian economy, mainly in rural communities and among indigenous groups in the Chiriquí province highlands. Weeds growing alongside coffee plants can provoke considerable economic losses for producers by interfering with the growth, development and yield of coffee crop in cultivated … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 6 Sep 2017 · 7,467 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleEvaluation of Wheat-Chickpea Intercrops as Influenced by Nitrogen and Weed ManagementA. Abdulahi, A. Dabbagh Mohammadi Nassab, S. Nasrolahzadeh et al.Wheat and chickpea are most important crops in dryland farming areas of Iran. Weeds have major impact on chickpea grain yield. This experiment was carried out to increase land use efficiency and weed suppression through intercropping in dryland agricultural research station-Sararood, Kermanshah, Iran during 2008-10. The experimental design layout was factorial split plot based on randomized complete block design with … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 4 Dec 2012 · 8,685 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleWeed Detection over Between-Row of Sugarcane Fields Using Machine Vision with Shadow Robustness Technique for Variable Rate Herbicide ApplicatorA. Muangkasem, S. Thainimit, R. Keinprasit, T. IsshikiProblem statement: Uniformly herbicide rate is used as a conventional practice in Thailand for controlling weeds in sugarcane fields. Since weeds usually grow in certain areas with non-uniformly distribution, uniform herbicide rate approach is not suitable and non-sustainable agricultural technique both in terms of economic an environmental aspect. To address these issues, Variable Herbicide Rate (VHR) was introduced. The VHR … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,238 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsMonitoring of Vegetation Degradation in various Landscapes of the Moyinkum Desert, KazakhstanOmirzhan Taukebayev, Bektemir Osmonali, Salavat Duisenbayev et al.This study is devoted to assessing the degree of vegetation degradation in various landscapes of the Moyinkum Desert, taking into account the taxonomic diversity of flora, the structure of phytocenoses, and the agrochemical condition of soils. The aim of the work was to identify areas with signs of disturbance and to analyse the factors determining degradation processes. It was established … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 17 Jul 2026 · 857 accessesView PDF Cite

Review ArticleOpen accessIn the keywordsGlobal Status of Herbicide Resistance Development: Challenges and Management ApproachesMeisam Zargar, Han Eerens, Elena Pakina et al.Chemicals are widely recommended for the suppression of weed in crop land. This paper attempts to a greater integration of ideas into the development of herbicide resistance. This may lead researchers to focus less on simply defining herbicide resistance and more towards comprehensive investigations of the resistance development. Weed expert in collaboration with plant biologists can work in synergy to … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 2 · 5 May 2017 · 8,466 accessesView PDF Cite
