in order to investigate the effects of input intensity on species diversity, composition and density of weeds in corn (zea mays l.), an experiment was conducted based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad, iran during the year 2009. treatments included low input, medium input and high input systems. low...

Conventional methods of weed control are weather dependent, costly and labour intensive. Indiscriminate use of chemicals for controlling weeds may pose environmental problems. Sorghum allelopathy is a new technique, which has been tested for controlling weeds of wheat (Triticum aestivum L.) as a substitute for chemical herbicides to reduce environmental pollution. Mature sorghum herbage contain...

efficacy of fomesafen and storm (bentazone+aciflorfen) herbicides on common bean (phaseolus vulgaris l.) weed control were evaluated in a randomized complete block design with four replications during 2008 in lorestan province. herbicides were applied postemergence at three trifoliate growth stage of common bean. herbicide injury on weeds reached maximum three days after treatments and common b...

evaluation of weed population and their interference on lentil varieties at different sowing date was investigated in a field experiment in khorramabad during 2005-06 growing season. the experimental design was a randomized complete block in factorial arrangement with 4 replications. the experiment had 3 factors including: planting date at three levels (autumn, winter, and spring) weed interfer...

Farming organic vegetable and crops have grown as a market desiring commodity. Weed control in farms has been costly and laborous and it has always been hard to achieve a proper weeding. A few chemicals are commonly applied in organic farming. Thermal weeding with flame burners seems a good solution; however, it has its own drawbacks, such as; damaging the main crops, low performance, being inf...

Field trials were conducted during the 2019-2020 cropping season to assess efficacy of S-metolachlor and flumetsulam (triazolopyrimidine sulfonanilide)+S-metolachlor (chloro-acetanilide) pre-emergence herbicides in controlling weeds maize at Chisumbanje estate. The experiment was laid out as a randomised complete block design (RCBD) with three treatments replicated thrice. Treatments used inclu...

The objective of this research is the replacement of hand weeding in organic farming by a device working autonomously at field level. The autonomous weeding robot was designed using a structured design approach, giving a good overview of the total design. A vehicle was developed with a diesel engine, hydraulic transmission, four-wheel drive and four-wheel steering. The available power and the s...
