Land and soil

Medium high to high land with loamy to sandy loam soil is the best suitable for

potato cultivation.

Seed rate

1.5- 2.0 t/ha (whole tuber); 1.2 -1.5 t/ha (cut tuber)

Seed treatment

Seed should be treated with 3% boric acid solution before sprouting for controlling

the common scab disease. In this case, boric acid should be melted with light heat

water. After cooling of the boric acid solution, it should be sprayed on potato tuber.

Time of sowing

15 to 30 November is the optimum time but sowing may be done in October to December.

Land preparation

Soil should be tilth properly by ploughing and laddering.

It was developed in Bangladesh by Crossing programme.

Plant: Medium height, intermediate type of stem, stem green

with no anthocyanine coloration. Leaves: Medium size of leaf

with no anthocyanine coloration on mid rib, very weak

waviness of margin of the leaflet. Tuber: Yellow skin, oval to

long oval shaped, medium size, shallow eye and light yellow

flesh. Tuber yield: 38-44 t/ha. Duration: 90-95 days.

BARI Alu-37

(2012)

It was introduced from Germany; Plant: Medium height,

intermediate type of stem, growth habit semi-erect and stem

green with very weak anthocyanine coloration on the base of

the stem. Leaves: Medium green leaf, leaf with no

anthocyanine coloration of mid rib, very weak waviness of

margin of the leaflet. Tubers: Brownish skin, oval to long

oval shaped, medium size, shallow eye and cream colour

flesh. Tuber yield: 32-40 t/ha. Duration: 90-95 days.

BARI Alu-38

(2012)

It was introduced from the Netherlands; Plant: Medium

height, intermediate type of stem, growth habit semi-erect to

spreading, stem green with no anthocyanine coloration.

Leaves: Medium size of leaf with no anthocyanine coloration

on mid rib, very weak waviness of margin of the leaflet.

Tubers : Brounish skin, oval to long oval shaped, medium to

large size, shallow eye and cream colour flesh. Tuber yield:

30-40 t/ha. Duration: 90-95 days.

Sowing method

Ridge to Furrow method

Fertilizer application

Cowdung 10 t/ha (at final land preparation), (i) Urea 350 kg/ha (50% at the time of

planting + 50% at 30-35 days after planting), (ii) TSP 100 kg/ha, (iii) MP 210 kg/ha,

(iv) Zypsum 84 kg/ha, (v) Micronutrient deficient in soil like ZnS04 and Boric acid

may be fertilized @ 12 and 5 kg/ha, respectively as basal dose. Zn fertilizer is not

allowed to mix with Phosphatic fertilizer.

Irrigation

Irrigations need for potato cultivation depending on the soil type. Sometimes, presowing

irrigation may be required. Normally irrigation at 8-10, 40-45 and 60-65 days

after sowing could be applied. Irrigation water should be maintained 2/3rd depth of

the furrow.

1.3 Intercultural Operations

Weeding followed by top dressing and earthing up should be done at 30-35 days after

sowing (DAS). In some cases, weeding may be required at 10-15 and 60-65 days

after sowing (DAS).
