Detailed Introduction to the American Giant King Soybean Variety
The American Giant King soybean generally has a plant height of about 85-90 cm, with a typical single plant reaching 1 m. It is a medium-stem soybean with a fan-shaped plant and large round leaves. The plant is stout and resistant to lodging, with 50-60 growing nodes, bearing true-form large round leaves. The flowers are of two colors, light white and purple, with a flowering period of about 40-50 days. The pod skin is brownish-yellow, and the pods are set compactly, with 3-4-seed pods accounting for more than 85%, while 5-seed pods are relatively few. The 1000-grain weight is 300-400 g. A single plant generally sets 200-300 pods and can produce 150-200 g of seed weight. An exceptional typical single plant can set about 800 pods and produce a net weight of about 500 g. This soybean variety has an especially high yield, so management measures must be strengthened: spring sowing can reach more than 1000 jin; summer sowing generally can reach a yield of more than 600 jin per mu.
The American Giant King soybean has a determinate pod-setting habit and has shown advantages such as tolerance to continuous cropping and strong stability in production. It also self-terminates growth, so there is no need to pinch off the growing tip. It saves labor and time, is drought- and waterlogging-resistant, lodging-resistant, and tolerant of fertilizer and water, and is highly resistant to yellow wilt and various other diseases.
The American Giant King soybean not only shows many advantages in planting and production, but also has good marketability, with uniform seeds and golden-yellow grains. According to the appraisal by the Quality Supervision and Testing Center of the Ministry of Agriculture of China, it contains 40.36% protein and 21.88% oil, making it a high-quality protein and high-quality soybean. It has high yields and good taste when used for tofu, soybean cake, bean sprouts, and various soybean products. Compared with other conventional soybeans, it yields 15% more when making soybean cake, 18% more when producing bean sprouts, 20% more when making tofu, and 2.5% more when producing soybean oil, with an average oil yield of 12.5% jin. Its market price is higher than that of others. According to the appraisal by the Quality Supervision and Testing Center of the Ministry of Agriculture of China, it contains 40.36% protein and 21.88% oil, making it a rare new high-yield, high-protein, high-quality soybean variety.
The American Giant King soybean has a moderate growth period and can be planted in spring and summer. Spring sowing takes 125-145 days (PBOG growth regulator must be sprayed), and summer sowing takes 105 days. It has strong adaptability and can be planted in most areas of northern and southern China. It is a rare new superior variety of super-high-yield, giant-seed soybean and is worth promptly introducing and multiplying.
Cultivation points: Apply 2-3 cubic meters of farmyard manure per mu as a base fertilizer, or 50-100 kg of nitrogen-phosphorus-potassium compound fertilizer. In addition, combine pest control with foliar topdressing. For spring sowing, use a plant-to-row spacing of 33 x 66 cm, planting 3000 plants per mu; for summer sowing, use a plant-to-row spacing of 25-29 x 66 cm, planting 3500-4000 plants per mu. When the weather is cool, the soil is cool, and the water is cool, you can seize the moisture and directly drill seeds in furrows, striving for full emergence in one sowing, with about 2-4 kg of seed per mu. To control nematode diseases, underground pests, and the like, an appropriate amount of Xianjing granular agent may be scattered in the sowing furrow.
