Abstract
The present investigation on“Studies on effect of integrated nutrient
management on growth, yield and quality of strawberry (Fragaria X
ananassaDuch.) cv. Camarosa grown under shade net conditions” was
carried out during Rabi season, 2018-19, under the supervision of the Department
of Fruit Science, at College of Horticulture, Venkataramannagudem, Dr. Y. S. R.
Horticultural University, West Godavari District of Andhra Pradesh. This
experiment was conducted with an objective to study the effect of INM on
growth, yield and quality parameters of strawberry cv. Camarosa. The
experiment comprised different combinations of inorganic fertilizers, organic
manures like FYM, vermicompost and biofertilizers like Arka microbial
consortium as 9 treatment combinations in randomized block design.
The study revealed the significant differences ingrowth, yield and quality
parameters of strawberry. Among the 9 different treatments,75% RDN + 25% N
through vermicompost + Arka Microbial Consortium coco peat performed the
best.
The growth parameters were significantly influenced by various
treatments from 30 to 120 DAP.Number of runnersplant-1, crown diameter,
number of leaves plant-1,leaf area plant-1, root length andtotal dry matter
production plant-1 were recorded maximum in the treatment75% RDN along with
25% N through vermicompost and Arka Microbial Consortium at 30,60,90,120
DAP respectively.The same treatment also recorded lowest plant mortality rate.
Maximum NAR was recorded in the treatment 50% RDN + 50% N through
vermicompost + Arka Microbial Consortium at 30-60 days interval, 50% RDN +
50% N through FYM at 60-90 days interval and 75% RDN + 25% N through
FYM at 90-120 days interval. Highest number of flowers plant-1
,
percentage of fruit set, lowest number of days taken to flower initiation and
lowest number days to fruiting from date of flowering were also recorded in the
treatment 75% RDN along with 25% N through vermicompost and Arka
Microbial Consortium.
Yield parameters liketotal number of fruits plant-1, fruit diameter, fruit
weight,fruit volume, yield plant-1,yield plot-1 andfruit yield hectare-1 were
recorded highest in the plants supplied with 75% RDN along with 25% N
through vermicompost and Arka Microbial Consortium.
Among the quality parameters shelf life , juice recovery percentage,TSS,
total sugars, reducing sugars,TSS: Acid ratio,ascorbic acidand anthocyanin
content were found to be highest in the treatment 75% RDN along with 25% N
through vermicompost and Arka Microbial Consortium. Non- reducing sugars
were found to be highest in the treatment 50% RDN + 50% N through
vermicompost + Arka Microbial Consortium while titrable acidity was highest in
the treatment 50% RDN + 50% N through FYM. Soil nutrient status was more in
the treatment 50% RDN + 50% N through vermicompost + Arka Microbial
Consortium while nutrient uptake was more in the treatment 75% RDN along
with 25% N through vermicompost and Arka Microbial Consortium.
From the present investigation, it can be concluded that integrated nutrient
management significantly influenced growth, yield and quality characters of
strawberry cv. Camarosa and the treatment with 75% RDN along with 25% N
through vermicompost and Arka Microbial Consortium recorded highest values
in terms of growth, yield, quality parameters and benefit cost ratio.
