How to Plant Sorghum Sudangrass? Detailed Guide to Planting Methods and Key Techniques

Sorghum sudangrass is an annual herbaceous plant of the Sorghum genus. Today, the editor will introduce the related questions of how to plant sorghum sudangrass. Let's take a look together!

1. How to plant sorghum sudangrass

You can select plump seeds free of pests and diseases, and sun-dry them for one or two days before sowing to increase the germination rate. The sowing time is concentrated from early April to June, which can ensure continuous production of green fodder throughout the summer. The entire growth period requires absorbing nutrients from the soil, so timely topdressing should be carried out according to growth conditions. Field management mainly focuses on clearing weeds and harvesting at the right time.

2. Propagation methods of sorghum sudangrass

1. Rust spot disease

Rust-colored spots appear on the leaf surface, initially at the tip of the leaf, then gradually expanding to the entire leaf surface and spreading to other leaves and other plants, causing large areas of leaves to wither and die; the nutritional value drops significantly, or even becomes completely worthless.

Prevention method: Soak the purchased seeds in antibiotic medication. Using Jinggangmycin aqueous solution diluted 200 times with water can achieve a preventive effect. Treatment method: Spray the leaf surface with Jinggangmycin diluted 1000 times with water for 2 consecutive days, preferably applied on a sunny afternoon; it can be cured in 3 days, and thereafter apply the medication once every 15-20 days. It can be fed 2 days after medication. [7] 

2. Rot disease

In the early stage, the stems and leaves at the tillering part of the roots rot and become moldy, and spread to the densely growing middle stems and leaves, causing the plant roots to rot and die. Only a few parts at the edges still grow normal stems and leaves. In severe cases, there is no more tillering, and the entire plant rots and dies at the roots.

Prevention method: Even spacing and thin planting. Because sorghum sudangrass has extremely strong tillering ability, you can thin the clusters after the seedlings grow 3-4 leaves, leaving 2-3 plants per cluster, which has a preventive effect on rot disease.
