What causes lodging?

What causes lodging? Lodging is most common in the later part of the crop’s growth, particularly during grain filling as more of the plant’s weight is shifted to the upper portion of the plant. The main factors that predispose a crop to lodging are: High levels of nitrogen – N causes lush growth and heavier plant tissue.

What are the factors that affect lodging in rice? Lodging is due to the interaction between susceptibility to the lodging of the plant and external force. Wind pressure and rain are the main factors of the external forces related to the lodging of rice plant.

What causes plant lodging? The causes of plant lodging are legion. High nitrogen levels, storm damage, soil density, disease, sowing date, overpopulation, and seed type are all contributing factors to lodging in cereal crops. The primary causes of plant lodging are over-crowding, wet soil, and excess nitrogen in soil.

What causes wheat to lodge? There are several main causes of lodging due to stem breakage this year. The stems of infected tillers readily break just above the soil line. Insectscan also cause stem breakage. Perhaps the most common culprit is wheat stem maggot.

What causes lodging? – Related Questions

What are the effects of lodging?

Dwarf varieties, which are shorter, are one way of reducing lodging. Lodging may occur at the root or the stem; the latter typically happens later, when the stem is dry and brittle. The timing of lodging can control its effect on yield, disease, grain moisture, quality, and evenness of ripening.

How do you keep rice from lodging?

Varieties that are prone to lodging require specific agronomic management to reduce their lodging potential, i.e. drill sowing, lower plant density and reduced nitrogen applied pre-permanent water.

What is stalk lodging?

Stalk lodging, by definition, is the breakage of the stalk below the ear. Severely lodged corn leads to increased harvest losses, increased harvest time, increased drying cost, and may result in volunteer corn the following year. Annual yield losses due to stalk lodging in the U.S. range between 5 and 25%.

Why is my corn lodging?

Root lodging may occur when root growth is insufficient to fully anchor the corn plant against the force of the wind. Corn product selection, soil and environmental conditions, insect damage, and herbicide injury are factors that can contribute to root lodging.

How does lodging affect yield?

While moderate lodging causes inconvenience at harvest, it can also reduce yield by interfering with crop growth processes such as water uptake and light interception.

What is the meaning of lodging and boarding?

The main difference between boarding and lodging is that boarding refers to the provision of both accommodation and meals while lodging refers to the provision of accommodation.

What are the basic principles of crop production?

What is soybean lodging?

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.

What is Baule unit?

A baule (BAWL or BOLE), or Baule Unit, named after German mathematician Bernhard Baule (1891–1976), is the amount of a given nutrient needed to increase the crop yield halfway from the current amount to the theoretical maximum. Effects of baules of different nutrients are multiplicative.

Why does excess nitrogen application cause lodging?

Excessive N causes “luxuriant” growth, resulting in the plant being attractive to insects and/or diseases/pathogens. The excessive growth can also reduce stem strength resulting in lodging during flowering and grain filling.

What is wheat culm?

Botanical description of the culm structure of wheat as implemented in the model. Culm structure is defined as a single root compartment and photosynthetic organs are organized in phytomers, chaff and grains. Culm organs are described explicitly and include structural, storage and mobile metabolites.

Which of the following elements imparts lodging resistance in the plant?

Cellulose, hemicellulose, and lignin and carbohydrate contents improve the physical strength of plant and thus contribute significantly to lodging resistance.

What is meant by crop logging?

Crop logging is a system of monitoring the nutritional status of plants by periodic and regular sampling and analysis of soil and plant parts. The primary aim is to be able to correct the nutritional problem while the plant is still standing and can benefit from the corrective measure.

Why are my corn stalks spindly?

Between roots stunted by compaction or early access to topsoil moisture, he has noticed some spindly corn stalks in his fields. “In many cases, delayed planting leaves corn a little more susceptible to earworms, and that opens the tip of the ear up to pathogens,” he said.

Why do corn plants fall over?

Corn plants usually get bent stems after severe wind or rain after pollination when the stalks are stronger, and yet carrying the weight of ears of corn. Tamp down around the roots or water at the base of the plants to push any loose soil around the roots and fill any air pockets near them.

How do I stop my corn from lodging?

Plant the corn in a wind-protected area. Corn is generally planted in blocks 3 or 4 feet wide and you can shelter an entire block. Although planting a windbreak is not a project quickly accomplished, an existing building or hedge can break the prevailing wind sufficiently to prevent corn from lodging.
