Experiments were conducted to show the effect of split application of nitrogen (SN) and boron (B) on hybrid True Potato Seed (TPS) production. The TPS-67 (♂) and MF-II (♀) were used as crossing materials. The experiments comprised two factors i.e., factor-A; nitrogen splitting (4 levels): 2 split (SN0-Conventional), 3 split (SN1), 4 split (SN2) and 5 split (SN3) where 50 kg N ha–1 applied as basal from total 300 kg N ha–1 with each split application and the rest 250 kg N ha–1 was splitted as per treatment at 10 days intervals started from 30 DAP (days after planting); and factor- B; boron (4 levels): 0 (B0), 4 (B1), 6 (B2) and 8 (B3) kg B ha–1 under split-plot design with three replications. We found that SN and/or B influenced the hybrid TPS production. The maximum yield (2160.1 mg) of TPS plant–1 was found from SN1B3 and the minimum (1001.8 mg) was in SN0B0. The maximum yield (172.81 kg) of TPS ha–1 was found from SN1B3 and the minimum (80.14 kg) was in SN0B0. The maximum weight (86.87 mg) of 100-TPS was found from SN3B3; whereas, the minimum (53.36 mg) was in SN0B0.

SummaryThree seasons of on-farm experimentation to develop potato production from botanical or true potato seed (TPS) under cool fertile conditions in West Java, Indonesia, are described. Twenty-three farmers experimented with two production systems: use of transplants, and use of seedling tubers produced in nursery beds. There was little yield difference between the systems, but an apparent progeny × system × season interaction was observed. All progenies were more resistant to late blight than the present cultivars grown from tubers. Appropriate matching of progeny and system gave seed of comparable quality with, but total yields slightly less than, certified imported seed of cv. Granola. Ware quality was slightly better than that of cv. Granola. Production costs were markedly less than for a tuber crop, making TPS ideal for small, resource-poor farmers.
