CastorPro #1 is a kind of middle-maturing hybrid variety.

1. Yield: Its ordinary yield is about 4500 kg/ha. For high-yield culture, its yield could be above 6750 kg/ha. The productive potentiality of single plants could be more than 1000 g.

2. Characteristics: It will take about 120 days from the seedlings coming out to main spikes becoming ripe. The plant is 225 cm high and has 4-5 first branches. The main spike is 65-95 cm long and looks like a pagoda. The capsules have dense thorns. The seeds are elliptical and there are some brown-red veins on them. The weight of 100 seeds is about 52 g. Kernel rate is 75%. The oil content of the seeds is 50% and oil content of the kernels is 67%.

3. Cultivation essentials: CastorPro is suitable to be planted in such regions where the frost-free period is more than 135 days. In such regions where the frost-free period is less than 135 days, farmers can grow seedlings first, and transplant later. Cultivation density: the row spacing is 100-120 cm, the crop interspacing is 70-80 cm. The population density of plants per ha is 10500-13500. In such areas where the temperature is high and the sunshine is strong, the number of plants per ha could be increased to 16500-18000.
