Plastic film maize cultivation involves covering the soil with plastic film to create a warm and moist environment for the maize seeds to germinate and grow. The plastic film helps to retain moisture in the soil, control weeds, and increase soil temperature, which can promote faster and more uniform germination. Additionally, the plastic film can also help to protect the young maize plants from pests and diseases. This method is commonly used in regions with cooler climates or where the soil is slow to warm up in the spring. **

The average yield of silage maize is typically around 20-25 tons per hectare. Achieving a yield of 40 tons per hectare would be considered high and would require optimal growing conditions, proper management practices, and high-quality seeds. While it is possible to achieve such high yields with the right combination of factors, it is not the standard yield for silage maize production. **

The cultivation of BT maize was banned in Germany due to concerns about its potential impact on the environment and biodiversity. There were fears that the genetically modified maize could harm non-target insects, such as butterflies and bees, which are important for pollination. Additionally, there were concerns about the development of resistance in pest insects to the BT toxin, leading to the need for increased pesticide use. As a result, the German government decided to prohibit the cultivation of BT maize to protect the environment and biodiversity. **

Yes, silage maize can have a yield of 40 tons per hectare under optimal growing conditions. However, achieving such high yields typically requires good soil fertility, proper irrigation, timely planting, and effective pest and disease management. Farmers can also use high-yielding maize varieties and employ best agricultural practices to maximize their crop yield. **

Maize weevils can survive for several months without food, as they are able to enter a state of dormancy when food is scarce. However, they are still capable of feeding on a variety of food sources, including crumbs, grains, and other stored food products. Therefore, they are not entirely dependent on a single food source and can survive by feeding on a variety of items. **
