Question

Describe the cultivation of bottlegourd under the following heads:
a) Selection of soil and preparation
b) Two improved varieties
c) Time of sowing and seed rate per hectare
d) Manure and fertilizer per hectare
e) Time of irrigation and method

Hint:

Bottlegourd vines need support; use trellising for better fruit quality and yield.

Answer 1

a) Selection of soil and preparation: Sandy loam rich in organic matter, pH 6.5-7.5, good drainage. Plough 2-3 times to fine tilth, incorporate 20-25 tons/ha FYM; prepare raised beds or furrows 2-3 m apart.
b) Two improved varieties: Pusa Summer Prolific Long (high yield, long fruits) and Pusa Naveen (early, prolific bearer).
c) Time of sowing and seed rate per hectare: Sow in February-March (summer) or June-July (rainy); seed rate: 5-6 kg/ha, sow 2-3 seeds/hill at 1-1.5 m plant spacing.
d) Manure and fertilizer per hectare: 20-25 tons/ha FYM basal. NPK: 100 kg N, 50 kg P₂O₅, 50 kg K₂O; half N basal, rest at 30 and 50 DAS.
e) Time of irrigation and method: Irrigate immediately after sowing; every 5-7 days in summer, less in rainy season (total 8-9 irrigations). Use furrow or drip method; avoid waterlogging.
