Abstract
Strawberry runners were transplanted in Fruit nursery at VCSG College of
horticulture Bharsar, during the rainy seasons 2014-2015, to investigate the effect of
different fertilizers and pesticide and their interactions on the vegetative growth, yield and
quality of strawberry plants cv. Shimla Delicious.
The experiment included 12 treatments resulted from the combination between four
fertilizer doses and three pesticides application methods. Results show that using
100:80:60 kg/ha NPK + vermicompost + runners dip with imidacloprid was significantly
found most effective in respect to plant growth characters viz., plant height (cm), number
of leaves per plant, fruit length (mm), fruit breadth (mm), days to fruit maturity, number of
runners per plant, yield characters viz., number of fruit, berry weight (g), yield per plant
(g), quality parameters viz., total soluble solids (0B), total soluble solid to titratable acidity
ratio, total sugar (%), reducing sugar (%), non reducing sugar (%), incidence of pest viz.,
leaf damage (%), fruit damage (%), pest population. Higher content of vitamin C and
anthocyanin were observed in 100:80:60 kg/ha + vermicompost + foliar application of
imidacloprid. The least values were recorded in the control.
After harvest strawberry fruits were treated with four concentration of CaCl2
namely (0.0%), (0.5 %), (1.0 %), (1.5 %). Among the treatments 1 % CaCl2 concentration
found most effective followed by (0.0 %), (0.5 %) and (1.5 %) in stored at refrigerator
condition. 1% CaCl2 under refrigerator condition increases the shelf life of strawberry till 9
days, viz., fruit length (mm), fruit breadth (mm) total soluble solids (0B), titratable acidity
(%), total soluble solid to titratable acidity ratio, vitamin C (mg/100 g) content.
