The Shannong series is a representative wheat series bred in Shandong Province, typically characterized by high yield, lodging resistance, and disease resistance. Shannong 27 and Shannong 28 are two of the better-performing varieties. So, which is higher yielding, Shannong 27 or Shannong 28? Details are as follows:
Which is more productive, Shannong 27 or Shannong 28?
The yield of Shannong 28 is higher than that of Shannong 27. Shannong 28 has an average yield of about 600 kg per mu and a production capacity of 700 kg per mu. In 2016, during a high-yield breakthrough, the yield per mu exceeded 800 kg.
How to choose the right wheat variety?
1. Select locally approved varieties
Wheat variety approval is generally divided into national approval, provincial approval, and introduction registration. Farmers in Shandong province only need to choose varieties approved locally; it's not necessary to check if they are nationally approved. Nationally approved varieties only mean they are suitable for a wider range of planting areas, not necessarily better quality.
2. Select the main varieties to promote
For example, wheat varieties such as Shandong Jimai 22 and Henan Bainong 207 have been promoted for many years and have stood the test of time. They have shown good performance in terms of yield, quality and stress resistance, and can be planted with confidence.
3. Select varieties with strong resistance to adverse conditions.
Resistance to adversity encompasses many aspects, such as disease resistance, insect resistance, cold resistance, drought resistance, and lodging resistance. Poor resistance will inevitably lead to a greater degree of damage.
4. Select varieties according to local conditions
(1) Soil fertility: If the local soil fertility level is high and the water and fertilizer conditions are good, wheat varieties with high yield potential should be selected; if the soil fertility level is average and the water and fertilizer conditions are poor, water-saving and drought-resistant varieties should be selected.
(2) Sowing time: If the local wheat sowing time is earlier, the wheat varieties to be selected should be winter or semi-winter wheat varieties; if the sowing time is later, weak spring wheat varieties can be selected.
(3) Sowing rate: Local custom is to choose large-ear varieties with medium tillering ability when sowing a large amount; and multi-ear varieties with strong tillering ability and high ear formation rate when sowing a small amount.
