You may have heard a lot about green bean inoculant and you may be wondering how important this is to the growth of your green bean plant. But what exactly is inoculant? What role does it play and why should we consider using one for our green beans or peas?
Green beans, black beans, peas, and so on are all members of the legume (Fabaceae) family. These legumes are well known for their aid in fixing nitrogen into the soil.
This article will go over what you need to know about green bean inoculant and other related info. So, read on to gain some knowledge.
What Is An Inoculant?
An inoculant is a type of bacteria or fungus that is often applied or added to the soil through the process of coating bean seed or pea seed. Known as beans or peas boosters.
Usually, the inoculants often come in powder but you may also come across liquid inoculants.
Inoculants & Nitrogen Fixing Bacteria
Plants require nitrogen to make amino acids which is a building block for protein and other plant components. Ideally, we have 78% of nitrogen gas in the atmosphere. But the problem is that nitrogen is in the gas form and plants can’t use or assimilate this.
The bacteria such as Rhizobium will work with the root system of peas and beans by creating nodes along with their roots. These nodes are responsible for fixing nitrogen gas and will change the nitrogen gas into a usable form for plant use.
Normally, the roots nodules of legumes such as beans and peas already contain Rhizobium bacteria. Hence, they already have the ability to fix nitrogen from the atmosphere. So you may wonder if you really need to inoculate your green bean seed.
It may not be necessary to inoculate your green beans seeds. However, when you apply inoculants to their seeds, it makes sure the correct type of bacteria that is specific to that legume is available to the plant when they germinate.
Another important note you should always remember is that once you’ve been growing and producing beans in your garden, you really don’t need inoculants. This is because these bacteria are already living and thriving in your soil even after you’ve planted and harvested.
Inoculating seeds involves coating or covering the seed surface with nitrogen-fixing bacteria such as Rhizobium or Bradyrhizobium. Inoculating seeds with nitrogen-fixing bacteria is always done prior to planting.
Inoculant For Green Bean And Peas
There are many bacteria used in inoculation. The bacteria often used for inoculating legumes like beans are Rhizobium bacteria. Rhizobium is also a pea inoculant. Therefore, the Rhizobium bacteria will only work for peas and beans and can’t be used for any other types of plants.
Another kind of nitrogen-fixing bacteria is Acetobacter, and this is isolated from sugarcane stem and root. Another type is Bradyrhizobium japonicum and this is used in inoculating soybean for fixing nitrogen.
How To Use Inoculant On Green Bean & Pea
It’s pretty easy inoculating your green bean and pea seeds. Simply purchase your legume inoculant from your local nursery store or online. But take note that some legume seeds may have already been coated with an inoculant. So ensure you know the type of legume seed you have.
Always make sure you have the correct inoculant specific to the type of legume you will be planting. There are different inoculants specific to different plants. So, whenever you purchase inoculants, ensure you read the package to know the type of plant it will be treating.
Also look at the expiry date to ascertain the inoculant is still viable. Inoculants often come in fine, black powder sealed in a plastic bag. However, you may come across some liquid inoculants.
So, to inoculate seeds, plant your green bean or pea into the planting hole. Then put a good amount of inoculant into the hole with the legume seed. Done inoculating your legume seeds, cover the seed hole with soil.
Importance Of Inoculation
Here are the benefits you stand to gain when you use inoculants on your green beans or peas:
- Normally, Rhizobium bacteria are present in many soils. But inoculating your legume seeds will ensure the correct or specific strain of bacteria required by that legume is present in the soil.
- Seed inoculation will offer your legume plant stronger and bigger yields. It will also give you a healthy plant.
- Inoculants make nitrogen more readily available for plants use.
- Once, you’ve inoculated and planted a legume crop on a particular soil, there will be sufficient availability of the specific bacteria you’ve inoculated. This is because the bacteria will live and thrive in the soil so far they have an adequate supply of food. This means you should constantly till your soil and incorporate compost and green matter back into the soil.
Additional Note On Green Bean Inoculant
Nitrogen is required by plants to make amino acid that is used to as a building block for proteins. Required for other essential components. Green bean and pea inoculant is an excellent way of supplying usable nitrogen into your soil.
However, not using inoculants on your legumes will not stop them from producing good yields. Matter of fact, many gardeners have grown legumes successfully without inoculating their seeds. This is because the bacteria for inoculating most plants are usually present in the soil.
Also, the garden that leguminous plants such as beans and pea have already been planted on may already have a good supply of Rhizobium in the soil. So it won’t be necessary to inoculate the soil.
Inoculants are simply boosters. Their work is to give you stronger and bigger yields. Therefore, if you want a larger and greater yield from your peas and beans, then you can use this inoculant. Also, if you have never grown leguminous crops such as beans and pea in your garden, inoculating the soil may be pretty beneficial.
