Adaptation and seed production of soybean cultivar Tainan No.4 for green manure

2000

A:PS

New soybean cultivar Tainan No. 4 was developed by pure line selection. It had small seed, rapid growth, high biomass and fertility, and was suitable for green manure. To evaluate the adaption at different locations and the optimal plant density for seed production. We investigate the adaption and seed production of Tainan No. 4 in Taiwan. The results were summarized as fellows: 1) In the spring season, the biomass at Ilan and Hualien areas were higher than the eastern area of Taiwan, Yunlin and Chiayi areas were higher than the other western areas. The biomass per hectare of Tainan No. 4. was 25,000 - 46,000 kg at 80 days after planting. 2) In the summer season, Tainan No. 4 was well adapted and the biomass of 20,000 kg at Yunlin, Chiayi, Miaoli, Changhua, Taitung, Ilan and Hualien. In the conclusoion, except Taoyuang area, Tainan No. 4 planted in wet field is suitable for green manure in the spring and summer. The fall cultivation in Tainan area is best for seed production of soybean Tainan No. 4, September 15 is optimum planting date. Tainan No. 4 yielded around 1,880 -2,050 kg/ha by harvester.
