Early Pest Identification in Greenhouse Crops using Image Processing Techniques
Early disease detection is a major challenge in agriculture field. Hence proper measures has to be taken to fight bioagressors of crops while minimizing the use of pesticides. The techniques of machine vision are extensively applied to agricultural science, and it has great perspective especially in the plant protection field,which ultimately leads to crops management. Our goal is early detecti...
متن کاملTesting the Suitability of a Terrestrial 2D LiDAR Scanner for Canopy Characterization of Greenhouse Tomato Crops
Canopy characterization is essential for pesticide dosage adjustment according to vegetation volume and density. It is especially important for fresh exportable vegetables like greenhouse tomatoes. These plants are thin and tall and are planted in pairs, which makes their characterization with electronic methods difficult. Therefore, the accuracy of the terrestrial 2D LiDAR sensor is evaluated ...
متن کاملEthephon Concentrates and Advances Harvest for Limited Cluster Greenhouse Tomato Crops
Ethephon (2-chloroethylphosphonic acid) was applied to single cluster greenhouse tomato crops (1000 ppm) at the green mature stage of fruit development or when 35% of the plants had fruits at the breaker stage. Fruits were harvested at the pink stage. Untreated fruit were harvested from 95 to 116 days after sowing whereas fruit from the green mature ethephon treatment were harvested from 92 to ...
متن کاملEffect of frequency of axillary bud pruning on vegetative growth and fruit yield in greenhouse tomato crops
In greenhouse tomato crops, several manual operations are performed each week to keep the plants in optimal growth conditions. But growers are trying to reduce labour costs by spacing out the manual operations. An experimental study was conducted on one particular operation, axillary bud deshooting. The aim is to determine the effect of the deshooting frequency on vegetative growth and fruit yi...
متن کاملFluoride levels in Soil and Crops of Tomato and Onion Farms of Zanjan
Background; Fluoride is an essential nutrient for the human body. The major routes of fluoride intake include food and drinking water, though the absorption of fluoride from food is much easier. The aim of this study was to evaluate the amount of fluoride in the soil and tomato and onion crops on farms of Zanjan. Methods; Three farms of each crop (tomato and onion) were selected randomly. Ea...
