Development of an autonomous weeding machine requires a vision system capable of detecting and locating the position of the crop. It is important for the vision system to be able to recognize the accurate position of the crop stem to be protected during weeding. Several shape features of corn plants and common weed species in the location were extracted by means of morphological operations. Eff...

Weed control is one of the most labor-intensive tasks for organic vegetable farms, and a realtime crop recognition system is the main challenge to develop the automatic mechanical weeding system. One solution using time-of-flight (TOF) 3D camera and advanced computation technique based on FPGA is proposed to address this problem. It has great advantages and can work reliably in the real harsh w...

A field experiment was conducted to find out the impact of weeding regime on performance three Aus rice. The experimental treatment consisted varieties rice viz. BRRI dhan28, Bere Ratna and Kajol Lata, four regimes no weeding, one hand at 35 days after sowing (DAS), two weedings 20 DAS 20, 50 DAS. laid in a factorial randomized complete block design with replications. Eleven weed species belong...

The use of plantations to manage extensive tracks of deforested lands in the tropics is a conservation strategy that has recently received considerable attention. Plantation trees can promote seed dispersal by attracting dispersers and creating favorable site conditions, leading to increased germination and establishment of indigenous trees. Subsequently, plantation trees can be harvested for p...

in order to compare the performance of different weed mangement methods in spring and waiting planting of rainfed chickpea this experiment was carrid out as split plot in randomized complete block design with four replications at maragheh agricaltural research station during 2004–2005 crop season. the main factors were planting ِdates including the waiting and spring planting. sub plots were wee...

in this study, the effects of weed control treatments and plant density on lentil (lens culinaris) yield and yield components as well as weed control efficacy were investigated. the study was conducted according to a split-plot arrangement based on randomized completely block design in three replicates in karaj in 2007-2008. the weed control chemical treatments in four levels (trifluralin herbi...

The main requisite for weeding-thinning machine is the location of the main stem of the crop. In this study, crops and their positions were detected using image processing techniques with the aid of artificial neural networks. Morphological operations were performed to singulate different objects in the images. Several shape features were fed to artificial neural network to discriminate between...

in order to evaluate the effects of crop cultivars and living mulchon sunflower yield and weed control, a field experiment was carried out as factorial arrangement based on a randomized complete block design with three replications in 2013. treatements were sunflower cultivars (‘azargol’, ‘allstar’, ‘farokh’) and weed control treatments (weed-free, weed-infestation and intercropping of fagopyru...

in order to study effects of application time of chevalier herbicide and integrate of illoxan with granstar on wheat and weed inahwaz, an experiment was conducted in ramin agriculture and natural resources university during 2007-2008, in split plot design by randomized complete blocks design with four replications. experimental factors was chevalier and integrate of granstar and illoxan herbici...

This research evaluated the effectiveness of biodegradable mulches for weed control in container-grown ‘Martin’ giant arborvitae (Thuja plicata) and measured the effects of these mulches on evaporation and substrate temperature. The experiment was carried out in the 2008 and 2009 growing seasons. Four biodegradable mulching materials were tested and compared with a chemical control (oxadiazon) ...
