Weed management in large-scale solar photovoltaic (LSS-PV) farms has become a great concern to the industry due scarcity of labour and ever-increasing price pesticides, which opens up possibilities for integrated farming, also known as agrivoltaics. Improper weed control may have multiple negative impacts such permanent shading module surface, pest housing damages communication cables, even bus...

In order to evaluate the effect of different periods of weed interference and weed control on plant height, seed yield and yield components of common bean, an experiment was conducted at the Agricultural and Natural Resources Research Center of Hamadan, Iran, in 2011. The experiment was a randomized complete blocks design with 3 replications. Treatments included two groups of weed interference ...

Weed infestations and associated yield losses require effective weed control measures in soybean and sugar beet. Besides chemical weed control, mechanical weeding plays an important role in integrated weed management systems. Field experiments were conducted at three locations for soybean in 2013 and 2014 and at four locations for sugar beet in 2014 to investigate if automatic steering technolo...

Weed control through crop rotation has mainly been studied in a nonspatial context. However, weed seeds are often spread beyond the crop field by a variety of vectors. For weed control to be successful, weed management should thus be evaluated at the landscape level. In this paper we assess how seed dispersal affects the interactions between crop rotation and landscape heterogeneity schemes wit...

  A factorial experiment, based on RCB design, with three replications was conducted to evaluate the effects of rhizobial inoculation, urea, and weeds on soybean performance in the field. The factors under study consisted of inoculation and non-inoculation, three levels of 0, 150, and 300 kg/ha urea, and weed-control and weed-infestation. Results showed that weed-control, inoculation and urea a...

Adviser: George Gogos Flaming is a thermal weed control method that can kill weeds within or between crop rows using heat. Mechanical cultivation is another weed control method which undercuts weeds between crop rows to kill them. A combination flamer/cultivator implement was designed to take advantage of the good qualities of both flaming and cultivation to provide excellent organic weed contr...

In order to investigate the effects of plant density, time and number of weed control on yield and yield components on corn hybrids, a factorial experiment in completely randomized blocks design with 3 replications was conducted in 2011 growth season at Research farm of College of Agriculture, University of Shahid Bahonar, Kerman. Weed control treatments were including: weed control during corn...
