Hybrid true seed production from potato mother plant as influenced by nitrogen splitting and boron

Abstract

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.
