Abstract
The present investigation entitled “Effect of pruning and fertigation levels
on growth, yield and quality of gynoecious cucumber (Cucumis sativus L.)
under naturally ventilated polyhouse condition” was conducted during Kharif,
2018 under naturally ventilated polyhouse at the College of Horticulture and
Forestry, Jhalawar. The experiment comprised of sixteen treatment combinations
consisting of four pruning (no pruning, pruning up to 30 cm, 60 cm and 90 cm
respectively) and four fertigation levels (80%, 100%, 120% and 140% RDF
respectively) in Split Plot Design with three replications.
The observations were recorded on 14 growth, yield and quality attributes
namely i.e vine length (cm) at 30, 60 and 90 DAT, number of branches per vine at
45 DAT, leaf area (cm2) at 30, 60 and 90 DAT, days taken to first female flower
appearance, number of flowers per vine, chlorophyll content (mg/g), length of fruit
(cm), diameter of fruit (cm), weight of fruit (g), number of fruits per vine, number
of deformed fruits per vine, fruit yield per vine (kg), fruit yield per m2 area and
total soluble solids (0Brix).
Treatments of pruning and fertigation levels significantly influenced the most of
growth, yield and quality attributes when they were used alone or in combination.
The treatment combination F3P2 (120% RDF + pruning up to 60 cm) was found
economical as it gave maximum yield (4.79 kg/vine), maximum net return (
399.30/m2) and B:C ratio (2.49). Further, this treatment increased the number of
fruits per vine (39.50), fruit yield per vine (4.79 kg), fruit yield per m2 area (26.33
kg) and minimum number of deformed fruits (1.00) over other treatments.
