Climate and Soil
Chinese Cabbage is a winter season crop. It thrives best at temperature from 15-21'C. The crop can be grown on a wide range of soils ranging from sandy loam to heavy soils.It is a non-heading strain of Chinese Cabbage which makes a high quality ‘saag’ due to its tender and succulent leaves. Its first cutting is ready by the middle of November.
Saag Sarson- (2013) : The plants are medium tall (47 cm height)with light green serrated leaves, leaf surface smooth and glabrous(non hairy), petiole thick and light green. The variety has erect bearing leaves which escapes them from sticking the soil during rains. Its leaves are low in oxalates and rich in vitamin C. The first picking is ready after 30 days of transplanting and it gives six pickings. Its average yield is 205 q/acre. The saag prepared from this variety has excellent flavor, taste and consistency.
Chini Sarson-1 : The plant is non-heading with semi-erect plant habit. It gives light green, broad, puckered and 12-15 leaves per plant. The leaf mid-rib is whitish, tender and succulent. It has quick growth habit and six to eight cuttings can be obtained. The first cutting can be had 30 days after transplanting. Average yield is 155 q/acre.
Sowing and Seed Rate : Sow the seed in raised nursery beds in mid September. Transplant the seedlings in the second fortnight of October. For sowing nursery, use 200 g of seed and for direct sowing, 1 kg seed per acre.
Spacing : Row to row and plant to plant spacing should be kept at 30-45 cm.
Manures and Fertilizers
Apply 15-20 tonnes of farmyard manure with 50 kg of N (110 kgof Urea) 25 kg of P2O5 (155 kg of Single Superphosphate) and 25 kg of K2O (40 kg of Muriate of Potash) per acre. Apply the whole of farmyard manure, P2O5 and K2O and 1/3 N before transplanting or sowing and the remaining 2/3 N as top dressing in equal proportion after the second and fourth cuttings for the growth of plants.
Harvest complete, fully developed leaves near the base without injuring the central bud point. Stop taking cutting by the end of December to get seed. Bolting starts in the last week of January.Harvest the seed by the end of April or early May.
A minimum isolation distance of 1000 meter should be maintained from other varieties of Chinese cabbage, sarson and turnip. One month old seedlings should be transplanted at spacing of 60 cm x 45 cm. Minimum three field inspections should be done for getting the true to type seed. The first inspection should be done at vegetative phase,second at bolting stage and third before harvesting of the crop. Any off type and diseased plants should be removed. The plants showing variation in leaf characters as well as early and late bolters should be removed.The crop should be harvested when most of the ripening seed stalks turn brown. Care should be taken to avoid shattering of seeds.After harvesting, the crop should left in the field for curing and drying for about a week before the seed threshing.
