---------------------------------------------------------------------***--------------------------------------------------------------------Disadvantages of Traditional methods of Weeding: Abstract - One of the key aspects of agriculture that affects crop productivity is weed . Since traditional weed management methods entail burning, pesticides, manual removal, crop loss, and reduced soil fertility, they also involve the use of trowels. This study suggests a technique to lessen the impact of weeds on agriculture by fusing deep learning with image processing. In order to recognise weeds in agricultural settings, centerNet models and Regionalbased Convolutional Neural Networks (RCNN) are used. In contrast to the two-stage RCNN technique, which is utilised for both detection and classification, the Center Net model is a one-stage object detector.

Impact Factor value: 8.226
Herbicides promote to pollution of the air, water, and soil. It may poison the soil, and subsequent pollution of the waterways will result from the chemicals being spread by precipitation to other locations.
The majority of herbicides are toxic.Because they have a larger quantity of acetic acid, which can seriously harm the eyes and skin, even organic herbicides have hazards.
Herbicides have a negative impact on people's health, including farmers, gardeners, and even consumers of food cultivated with them.
(ii)Hand removal
In India, where basic agricultural activities are the majority of peoples' occupation. More than half of the population of India is involved in Agriculture and related activities. Weeds contribute to our country's declining economy and create severe yield losses in the food producing industry. A plant that grows where it is not wanted is called a weed. A weed is a plant that grows where it is undesirable and another plant ought to grow because it is unattractive, useless, and harmful. A plant that has more potential for damage than for good is also considered a weed. All weeds are undesirable plants, yet not all undesirable plants are necessarily weeds. Due to the uneven spacing of the plants, weed identification in vegetable plantations is more difficult than weed identification in crops. To boost crop productivity and decrease weed-related economic loss every farmer should practise weeding. One of the most crucial practises in many crops is weeding. Weeds compete with main crops for resources like water, sunlight, soil nutrients, and space, so weeding is important. Vegetable yield is decreased by weeds, but their quality is also decreased. So weeds has an impact on the growth of vegetables. In addition to lowering vegetable yield, weeds can lower their quality, which has an impact on their growth.There are many traditional methods of weed control like Herbicides, Transplants , mulching , hand removal,flaming etc but those techniques have many disadvantages. Some of them are listed below:

Heavy work and stress on the labour force
Difficult if the soil surface is not moist and loose
Expensive (if wages are high)
Difficult to recognise and eradicate some grassy weeds in their early stages (e.g. weedy rice, Echinochloa spp.). Such weeds must be eliminated from the field when they are in bloom. If pulled and thrown into standing water, weeds might live.
(iii)Transplanting
High labour costs
Takes high time for recovery after transplanting,
plants develop more slowly than when they are grown directly from seed. Harvesting is also delayed.
(iv)Mulching
|
Years of heavy mulching may cause soil to accumulate over the crown area of plants.
One disadvantage of extensive mulching may be the price of some materials.
