Abstract/ Executive Summary:

The size of cut seed piece had significant influence on the number of main stems yield of tubers per hill and yield of tubers per hectare. Plant spacing had no significant effect on the number of main stems per hill, although the number of tubers per hill increased with increase in plant spacing. The yield of tubers per hill increased significantly with increase in plant spacing. However, the yield of tubers per hectare did not follow the same trend. The highest yield of tubers (30. 4 t/ha) was obtained from the largest seed piece (35 g) planted at 50 cm x 22.5 cm spacing. But the highest net profit (Tk. 15.088/ha ) was obtained from 15 g seed piece planted at 60 cm x 15 cm spacing. The seed rate in the treatment combination was 1.7 t/ha.

Keywords: Cut seed piece, Plant spacing, Yield, Profitability, Potato

Location: Bangladesh Agricultural University Horticulture Farm, Mymensingh

Start Date: 00-00-1988

End Date: 00-00-1989

Program Area: Seed Technology

Commodity: Potato

Objectives:

To find out the best combination of cut seed piece and plant spacing for the production of potato under Bangladesh condition.

Methodology:

The study was carried out at the Bangladesh Agricultural University Horticulture Farm, Mymensingh during the 1988-89 growing season. The treatment of the experiment. The 2-factor experiment was laid out in the randomized complete block design with 3 replication. The size of unit plot was 3.0 m x 2.7 m. Locally produced (once multiplied) grade 2 ( 35-45) seed tubers of Diamant variety were used. The cut seed pieces were planted on 9 December 1988. The crop was fertilized with 276 kg urea, 185 kg triple superphosphate and 322 kg muriate of potash per hectare. In addition cowdung manure was applied @ 10 tons/ha. irrigation, weeding, mulching, earthing up and other intercultural operations were done as and when needed. The crop was harvested on 10 March 1989. Data on yield components and yield of tubers were recorded from 20 plants selected at random from the middle rows of each unit plot.
