This document provides information on cucumber production in polyhouses. Some key points: - Cucumbers require protection from pests/diseases and adverse climate which polyhouses provide, allowing for high productivity, quality, and off-season cultivation. - Optimal temperatures are 15-24°C daily average, with night temperatures of 18-20°C and day temperatures of 20-22°C. Summer planting is February-March and winter is August-September. - Popular hybrid varieties include Multistar, Emistar, and Falconstar. Crop duration is 90-120 days. Yields of 4-5kg per plant can be achieved in February-March and 2-3kg in August

Polyhouse

2. Why protected cultivation is needed
• Protection from insect-pest and diseases
• Protection from adverse climate
• High productivity
• High quality and continuous availability
• High quality and continuous availability
• Off-season cultivation is possible
• Minimum use of pesticides
• More income per unit area
• Best way for judicious use of natural resoucess

3. Climate Requirement
• Although maximum growth occurs at a day and
night temperature of about 28°C.
• Maximum fruit production is achieved with a
night temperature of 19-20°C and a day
temperature of 20-22°C.
temperature of 20-22°C.
• The optimum daily average air temperature is
15- 24°C (65-75°F).
• Optimum temperatures for growth are at night,
about 18°C, and during the day, about 28°C
accompanied by high light intensity.

4. Planting Time
Growing season of Cucumbers is relatively short, lasting 90-
120 days for greenhouse varieties.
Summer Crop Season
Feb sowing with seedling
March sowing can be with Direct Seed sowing
Winter Crop Season – August September up to December
Winter Crop Season – August September up to December
Direct Sowing is recommended genrally when temp is
Above 15 C.
Generally for polyhouse: Parthenocarpic cucumber i.e.
they produce fruit without the need of pollination.

5. Cucumber Hybrids for Polyhouse
• 3 types of cucumbers based on flowering habit:
1. That produces only female flowers Gynoecious
2. The Gyno-monoecious which is predominantly produce
female flowers with some male flowers
3. Monoecious: has both male and female flowers
3. Monoecious: has both male and female flowers
• Popular hybrids:-
February to March - Multistar, Emistar, Captainstar,
Falconstar, Judson, Festa, 5232
May June – 2833 (Seminis) , Summer Crown (Hi-gen)
September - Multistar, Falconstar, Judson, Feista
October - Kingstar

6. Duration of Crop
• Double row sowing in summer crop and Single
row sowing in winter crop recommended
• For sandy Loam soil , two drip line
recommended, For Clay soil single drip line can
be use
be use
• Plant population 8000-10000 plants per acre.
• Flowering at 30 days after sowing.
• 45 days for getting first Harvest.
• 100-120 days crop cycle.

preperation with Microbs Culture
• Microbs like Trichoderma, Psedomonas,
Paecilomysis , PSB, KSB , Azotobactor should be
added @ 2 Liter per acre each before planting.
• Soil should be moist make Soil Alive (Living Soil)

15. Methods of density
1. Single rows (for winter crop and low greenhouses):
• 130-150cm between rows
• 40-50cm between plants in row
• 40cm is recommended for low vigor varieties
• The density is 1.7-1.8 plant/m2
• The density is 1.7-1.8 plant/m2
II. Double rows (for high well ventilated greenhouses):
• 180-200cm center-center of beds
• 50-60cm in between pair rows
• 40-50cm between plants in row
• Density is 2.4-2.6 plants/m2

27. Fertilizer and Water Requirement
Cucumber needs continuous water supply depends on soil
and climate
In general, green house cucumbers are irrigated through
drip system of irrigation and fertilizers are applied through
water: Fertigation
water: Fertigation
In addition to NPK, calcium is also required for fruit quality
and higher yields
Calcium should always applied through soil, not spraying
Boron Spray is require at the time of Flowering and Fruit
Setting.

28. EC & pH Requirements
•Soil Testing and Water Testing is very
important.
•In soil testing, Check- EC, pH, Organic
matter, Major and Micro nutrients.
•Irrigation water should have EC <1 and pH
should be 6.5 to 7.0
should be 6.5 to 7.0
•Fertigation water should have EC = 1.5
and pH should be 6.25.
•Soil EC should be <0.8 and pH should be
5.5 to 7.5.

29. Harvesting and Yield
From transplanting to first harvest: 35-40 days
in gynoecious cultivars
In Good managed crop:
Febuary-March Crop Yield = 4-5 Kg/ per Plant
August-Sept. Crop Yield =2-3 Kg/ per Plant
August-Sept. Crop Yield =2-3 Kg/ per Plant
May- June Crop Yield =2 Kg/ per Plant
Gynoecious type cucumber Crop takes
3-4 month crop duration

30. Nutrient Influence Each Other

•Due to high fertilizer application
•Due to mixing of two or more water soluble fertilizers and using less water for dilution
•Due to less irrigation and more fertigation in winters
