@ttownsend46#732 Thanks very much Sir for nice and encouraging comments about Gossyp Issue 4 .
Thank you for the information. Information about intercropping, double cropping and crop rotations are important for an understanding of cotton production practices, and I appreciate Gossyp Issue 4.
Thanks very much for explaining in detail the choices of intercropping/relay cropping systems being adopted in different parts of China.
1. REPLY: It is very important for farmers in specific areas to choose suitable intercropping system. When choosing the system, we should not only consider the output and net income, but also the material and labor input. Because relay intercropping is usually more labor-intensive than regular intercropping, farmers with limited land but more labor can choose intercropping, while farmers with limited labor force can choose regular intercropping. Farmers can also choose or make a decision according to their own needs or the guidelines issued by the local agricultural technology extension center. Sometimes farmers will consciously choose intercropping system according to their own experience to reduce the risk of diseases and insect pests.
2. REPLY: Generally, different regions adopt different intercropping systems in China. However, in a specific region, there are several major intercropping systems. For example, in Gaotang county of Shandong Province, cotton-peanut intercropping and cotton-watermelon intercropping are major intercropping systems, while in Juye county of Shandong Province, relay intercropping of cotton-garlic, and cotton-pepper are mainly adopted. The specific intercropping system also changes with the times or market demand.
The topic of intercropping is very interesting. The authors report that there are more than 100 intercropping systems involving cotton in China. How does an individual farmer in a specific location know which system is best for his/her circumstances?
Do all farmers in a region tend to use the same intercropping system, or does each farmer choose which system to use, with the result that there are many systems being used in each region each season?
