What is lodging in plants?

Lodging refers to the permanent displacement of aboveground portions of crops from their vertical stance due to stem buckling (stem lodging) or failure of the root–soil anchorage system (root lodging).


What causes lodging?

Lodging is when the crop falls over. A normal vertical crop is finely balanced, so anything that upsets the balance will cause it to lodge: strong winds, heavy rain, a very wet soil during late grain filling, tall thin stems that bend, root or stem rots that weaken the plant base.


What causes lodging in cereals?

Lodging in cereals is often a result of the combined effects of inadequate standing power of the crop, and conditions such as rain, wind, hail, topography, soil, previous crop, and others.


What is lodging in soybeans?

Larvae can move into the main stem of a soybean plant where they can tunnel into the plant as it matures or girdle the stem. Significant soybean yield losses generally occur from larval girdling, which can result in lodging and harvest losses. Lodging is typically most severe in earlier planted soybean plants.


Why do crops Lodge?

Lodging is usually caused because of a combination of morphological (structural) and environmental causes. Lodging can simply be as a result of adverse weather such as high winds, heavy rainfall or hail literally pushing the crop over. There are, however, a number of factors that will increase the risk of lodging.


What is lodging in maize?

Lodging happens when the stalk breaks below the ear. This means yield losses, increased time to harvest and may also influence the grain quality. Lodging usually occurs in the second half of the season as the maize plant starts to mature.


What causes lodging in rice?

Lodging occurs when plant stems weaken to the point they can no longer support the weight of the grain causing it to fall over. As growers push for maximum grain yield, lodging is becoming a significant factor in rice production, increasing the time and cost of harvest and often resulting in significant yield loss.


What is sugarcane lodging?

1. Introduction. Lodging can be defined as the loss of crop erectness due to either stem failure or stool tipping (Berding and Hurney, 2005).


What is the difference between logging and lodging?

The only main difference is that water logging occurs when water is supplied or water is accumulated in the field (here the plants do not fall) and water lodging occurs during stormy conditions where the plants get laid off along with accumulation of water.


Why are soybeans lodging?

The most likely causes are excessive rainfall or irrigation during the vegetative and early reproductive stages, high populations, low potassium soil test levels, and variety selection. Soybean varieties differ in susceptibility to lodging, and producers should consider this characteristic when selecting varieties.


Why do soybeans Lodge?

Overplanting, especially when soybean seed is drilled, can cause plants to lodge because plants grow taller and more slender as they compete for light.


How do you combine soybeans?

For combining soybeans, farmers attach a grain head to the front of the combine. This type of head has a big rotating reel with finger-like elements across the entire width of the head. Once the farmer is in the soybean field, he lowers the grain head to ride just above the ground.


What is a lodging crop?

Lodging (agriculture) Lodging is the bending over of the stems near ground level of grain crops, which makes them very difficult to harvest, and can dramatically reduce yield. Lodging in cereals is often a result of the combined effects of inadequate standing power of the crop, and conditions such as rain, wind, hail, topography, soil, …


What is a lodged field?

A badly lodged field of barley from a distance. Lodging caused by humans flattening grain to make a crop circle. Lodging is the bending over of the stems near ground level of grain crops, which makes them very difficult to harvest, and can dramatically reduce yield. Lodging in cereals is often a result of the combined effects …


Why is there a lot of lodging in cereals?

Lodging in cereals is often a result of the combined effects of inadequate standing power of the crop, and conditions such as rain, wind, hail, topography, soil, previous crop, and others. Lodging affects wheat, rice, and other cereals, and reducing it is a major goal of agricultural research.


Root lodging

Root lodging is the most damaging and the most prevalent type of lodging in the UK.


Stem Lodging

Stem lodging can reduce stem strength by 50% as it gets closer to harvest due to grain fill.

Apart from a dent in grower or agronomist pride there are serious cost implications that arise from a lodged crop.


What causes a crop to lodge?

A normal vertical crop is finely balanced, so anything that upsets the balance will cause it to lodge: strong winds, heavy rain, a very wet soil during late grain filling, tall thin stems that bend, root or stem rots that weaken the plant base. Winds associated with excess water are the worst combination.#N#Lodging destroys the canopy structure. Solar radiation is no longer intercepted efficiently with high light to young upper leaves and low light to old leaves. Heads are covered in the tangle and the collapsed crop becomes more susceptible to pests and diseases.#N#Lodging during early stem elongation has a relatively small effect on yield as the crop will right itself and reform the canopy. The stem nodes alter the angle of extension making new growth vertical (see the nodes in the centre of the above photo).#N#From anthesis onwards the effects of lodging are large. For every day that the crop is lodged yield declines by more than 1% (Stapper and Fischer 1990). So for crops severely lodged shortly after anthesis and remaining so, final yield will be less than half that of the upright crop.#N#Any lodging also makes harvesting more difficult and increases the likelihood of losing grain during harvesting.


What happens when a plant is lodging before flowering?

Plants flattened. If lodging before flowering, then plants may recover and grow upwards. Lodging can reduce yields and increase diseases. When lodging occurs before flowering, the plant can often recover and yield is not seriously affected.


What is lodging in agriculture?

… Lodging is the displacement of stem and roots of plants from their proper and vertical placement either due to the higher nitrogen application, higher wind velocity, rainfall, excessive soil moisture, and date of sowing or over plant density etc. Cereal crops are more susceptible to the effects of both root and stem lodging. Both type of lodging can occur singly or coincidentally but their effects on crop production overall reduces the health and harvest (Dahiya et al., 2018). It increases cost of harvesting with decrease in quality because it occurs close to harvest and cereals are prone to lodging near harvest. …

What is waterlogging in agriculture?

In agriculture, various crops need air (specifically, oxygen) to a greater or lesser depth in the soil. Waterlogging of the soil stops air getting in. How near the water table must be to the surface for the ground to be classed as waterlogged, varies with the purpose in view.


Why is waterlogging important in agriculture?

In irrigated agricultural land, waterlogging is often accompanied by soil salinity as waterlogged soils prevent leaching of the salts imported by the irrigation water. From a gardening point of view, waterlogging is the process whereby the soil blocks off all water and is so hard it stops air getting in and it stops oxygen from getting in.
