How many jin per mu can castor beans generally yield?

AbstractThe average yield of castor beans is about 400-1000 jin per mu. Depending on the variety, region, and cultivation management, the yield varies greatly. Castor beans are mainly grown in northern China, generally 1 season per year. Double-season planting began in 2009, and the yield per mu in the early season is slightly higher than that in the late season.

I. Castor bean yield per mu

1. The average yield of castor beans per mu is about 400-1000 jin. The level of yield per mu is mainly affected by factors such as climate, environment, and cultivation management techniques. The main producing areas of castor beans are in northern China, generally 1 season per year.

2. It is also grown in southern China, but the yield per mu is lower than in the north, so fewer people grow it. Double-season planting roughly began in 2009, and the yield per mu in the early season is higher than in the late season. Of course, high-quality varieties and good management techniques will increase castor bean yields.

II. Suitable planting time for castor beans

1. Castor bean is an annual or perennial herbaceous plant. It is now widely grown in plain areas in China. The planting time of castor beans should be chosen according to the region.

2. Southwest China: suitable for planting in winter, spring, and summer.

3. Tropical areas of southern China: suitable for planting in winter.

4. Southern China and Southwest China: suitable for planting in March-April.

5. East China and North China: suitable for planting in April-May.

III. Castor bean planting cost

1. The main costs of growing castor beans include: land rent, seed costs, pesticides, fertilizers, labor, etc. Land rent varies by region, but in most areas it is generally about 300-600 yuan per mu, while the cost of buying seeds for growing 1 mu of castor beans is about 300 yuan.

2. The cost of fertilizers and pesticides generally does not exceed 600 yuan, while labor cost is the largest input cost among them. Adding working capital, it is about 1500 yuan, so the total cost of growing 1 mu of castor beans is about 2700 yuan.

IV. Castor bean planting profit

The planting profit of castor beans is mainly obtained from planting costs, market prices, and planting yields. According to feedback from most growers, the current yield of growing 1 mu of castor beans is generally about 500-800 jin. At the current market purchase price of 7 yuan per jin, the income per mu is 5600 yuan. After deducting the planting cost of 2700 yuan, the net income per mu is about 1000 yuan, so the planting prospect is still very good.
