Abstract
The present investigation entitled “Studies on stage specific fertigation
in European cucumber (Cucumis sativus L.) under naturally ventilated
polyhouse” was carried out during 2018-19 at Centre of Excellence for Protected
Cultivation (CEPC), Horticultural Research Station, Dr. Y. S. R. Horticultural
University, Venkataramannagudem, West Godavari District, Andhra Pradesh.
The experiment was laid out in factorial randomized block design with three
replications comprising twelve treatment combinations which include three
factors viz., three levels of nitrogen as first factor (80 kg/ha, 120 kg/ha and 160
kg/ha), two levels of phosphorus as second factor (60 kg/ha and 90 kg/ha) and
two levels of potassium as third factor (80 kg/ha and 120 kg/ha).
Studies on stage specific fertigation of different levels of NPK
significantly influenced plant growth, yield, quality attributes and nutrient
uptake of cucumber crop. Among N levels, maximum vine length, number of
leaves per plant, leaf area per plant, internodal length, leaf chlorophyll content,
fresh and dry weight of plant, fruit set percentage, number of fruits per vine, days
to final harvest, fruit length, fruit diameter, fruit weight, fruit mesocarp thickness,
yield per plant, yield per plot, estimated yield, TSS, ascorbic acid content, fruit
moisture content, soil pH, electrical conductivity, available nitrogen, phosphorus,
potassium, plant uptake of nitrogen, phosphorus and potassium, minimum days
to first female flower appearance, node number at which first female flower
appear, days to first harvest and titrable acidity were recorded with the stage
specific application of 160 kg/ha of N.

Among P levels, maximum vine length, number of leaves per plant, leaf
area per plant, internodal length, leaf chlorophyll content, fresh and dry weight of
plant, fruit set percentage, number of fruits per vine, days to final harvest, fruit
length, fruit weight, yield per plant, yield per plot, estimated yield, ascorbic acid
content, fruit moisture content, available nitrogen, phosphorus, potassium, plant
uptake of nitrogen, phosphorus and potassium, minimum days to first female
flower appearance, days to first harvest and titrable acidity were recorded with
application of 90 kg/ha of P .
Among K levels, maximum vine length, number of leaves per plant, leaf
area per plant, internodal length, leaf chlorophyll content, fresh and dry weight of
plant, fruit set percentage, number of fruits per vine, days to final harvest, fruit
length, fruit weight, yield per plant, yield per plot, estimated yield, ascorbic acid
content, fruit moisture content, electrical conductivity, available nitrogen,
phosphorus, plant uptake of nitrogen, phosphorus and potassium, minimum days
to first female flower appearance, node number at which first female flower
appear, days to first harvest and titrable acidity were recorded with application of
120 kg/ha of K.
The application of 160 kg/ha of N, 60 kg/ha of P and 120 kg/ha of K
resulted in significant increase of vine length, number of leaves per plant, leaf
area per plant, internodal length, leaf chlorophyll content, fresh and dry weight of
plant, fruit set percentage, number of fruits per vine, days to final harvest, fruit
length, fruit weight, yield per plant, yield per plot, estimated yield, fruit moisture
content, plant uptake of nitrogen, phosphorus and potassium, and benefit cost
ratio. Minimum days to first female flower appearance, minimum days to first
harvest and minimum titrable acidity were also recorded in the same treatment
combination.
