Abstract
|
|
|
|
The various cultural practices of bulbils were tested for seed tuber production in Chinese yam (Dioscorea batatas Decne.). To obtain amount of seed tuber, yam bulbils were sowed from early April to early May. The late sowing reduced average tuber weight, and consequently the amount of small tubers less than 20g increased highly. The optimum seeding rate of bulbils was 200 kg/10 a for production of seed-tubers. The average tuber weight was decreased according to increasing of seeding rate, so the amount of small tubers among total harvested tubers increased greatly at high seeding rate. Tuber size was affected by bulbil size. Seeding of the larger size bulbils result in increased sprouting rate, each tuber weight and tuber yield per unit area.
