English (parthenocarpic) cucumber under polyhouse

Parthenocarpic, or seedless, English cucumber (Cucumis sativus) is the standard cucurbit choice for polyhouse cultivation in India. Polyhouse films and insect-exclusion nets keep pollinators out of the protected environment, so commercial production inside polyhouses depends on parthenocarpic gynoecious hybrids that set fruit without pollination.

Key characteristics

Family: Cucurbitaceae
Key variety: Pusa Seedless Cucumber-6 (ICAR-IARI, released 2015-16)
Yield under low-cost polyhouse: ~126 t/ha (1260 kg per 100 m2)
Rationale for parthenocarpy: polyhouse excludes pollinators, requires seedless varieties

Cultivation

The crop is grown year-round inside naturally ventilated or fan-and-pad polyhouses with vertical training on overhead wires or twine. Plants are pruned to a single leader, and lateral side-shoots and tendrils are removed regularly to maintain canopy structure. Fertigation through drip is standard. Pusa Seedless Cucumber-6 from ICAR-IARI is the leading Indian public-sector release for this system.

Adoption context

Capital cost of a polyhouse runs to Rs 46-63 lakh per acre depending on specification, with each crop cycle requiring an additional Rs 2.5-3 lakh in operating costs. The Mission for Integrated Development of Horticulture (MIDH) subsidises 50% of approved norm costs, capped at Rs 1 crore per project, for polyhouse establishment. Strong, predictable supply to urban supermarket and quick-commerce channels makes English cucumber one of the more economically attractive polyhouse crops along with Capsicum Polyhouse.

Limitations

High up-front investment, fluctuating supermarket prices and the need for skilled labour limit adoption to peri-urban and well-capitalised producers.
