(Keladi Shivappa Nayaka University of Agricultural & Horticultural Sciences, Shivamogga, 2021-12-10) SACHIN BONDADE; Dr. B. HEMALA NAIK; Dr. THIPPESHA. D
An experiment was conducted at Zonal Agriculture and Horticultural Research Station, Shivamogga, during Rabi 2020, to study the effect of foliar application of bio-stimulants and bio-inoculants on Arka Bahar variety of bottle gourd. The experiment was carried out using randomized complete block design with three replications and ten treatments. The different combinations of biostimulants and bioinoculants such as Sea weed extract, Humic acid, Jeevamrutha, Azospirillum and Pseudomonas fluorescens were used as treatments with recommended cultural practices to study the impact of different treatments on growth, yield and quality parameters. It was observed that, T10 {Sea weed extract (0.5 %) + Azospirillum (4 ml/l) + Pseudomonas fluorescens (4 ml/l)} has recorded the highest vine length (778 cm), vine girth (26.06 mm), number of internodes (91.40), inter-nodal length (12.90 cm), number of branches (17.66), leaves per plant (125.60), leaf area (5946 dm2), leaf area index (198.23), total dry matter accumulation of plant (369.70 g at 90 DAS), total fresh weight at 90 DAS (623.40 g/plant), days to first female flower appearance (51.53), days to first male flower appearance (48.43), nodes on first female flower appear (9.33), number of female flowers (24.43), number of male flowers (71.83), fruit set per cent (74.09 %), number of fruits per plant (16.40), fruit length (41.63 cm), fruit girth (18.17 cm), flesh thickness of fruit (71.23 mm), fruit weight (1013.40 g), fruit yield per vine (16.65 kg), total yield (51.27 t), number of seeds per fruit (645.67), seed weight per fruit (105.27 g), seed yield per vine (1.73 kg), seed yield per hectare (52.87 q), Ascorbic acid content (8.07 mg/100g), TSS (12.200 Brix), Reducing sugar (8.17 mg/100g) %), Crude fibre content (1.65 g/100g). The economic analysis clearly showed that, the maximum net returns (Rs. 4,03,045.70) and B: C ratio (2.47) was also found in treatment T10.

Maximum total chlorophyll content (2.29 mg/g of fresh weight) was observed in plants sprayed with CCC 1000ppm. The plants sprayed with CCC 1250ppm took minimum number of days for flowering (69.20) whereas longest duration of flowering was observed in plants sprayed with 125ppm GA3. The minimum days from flowering to harvesting (25.93) was recorded in the plants sprayed with BA 100ppm. The maximum number of flowers per plant (28.33), fruit set (76.45 %), number of fruits per plant (21.67) and yield per plant (307.78 g) was recorded in plants sprayed with 125ppm GA3. The maximum fruit weight (16.07 g), length (3.92 cm) and breadth (2.85 cm) was recorded in plants sprayed with CCC 1000ppm. The fruit quality parameters like total sugars (6.84 %), sugars to acid ratio (11.03) and minimum titrable acidity (0.62 %) was recorded in plants sprayed with CCC 1000ppm. The application of GA3 125ppm resulted in maximum Cost: benefit ratio (1: 2.56). Among different growth regulators, application of GA3 125ppm was found to improve growth and yield parameters of strawberry.

INDUCTION OF FLOWERING TO INCREASE THE FRUIT SET WITH MORE NUMBER OF HERMAPHRODITE FLOWERS IN BHAGWA VARIETY OF POMEGRANATE (Punica granatum L.)
(University of Agricultural and Horticultural Sciences, Shivamogga (Mudigere), 2015-06-21) VIDYA V. ANAWAL; Dr. P. NARAYANASWAMY; Dr. SURESH D EKABOTE
The field investigations were carried out during 2014-15 in the farmers field at Hosayalanadu village, Hiriyur taluk, Chitradurga district of Karnataka to study the “Induction of flowering to increase the fruit set with more number of hermaphrodite flowers in Bhagwa variety of pomegranate (Punica granatum L.)”. The plants which received ethrel 250 ppm at new flesh stage recorded minimum duration for 50 per cent (12.67 days) and 100 per cent flowering (30.44 days) and also produced maximum number of productive hermaphrodite flowers (68.33) followed by minimum number of intermediate flowers (25.22) which are unproductive. The application of NAA 100 ppm recorded maximum size of the flowers in terms of length and diameter in hermaphrodite flowers (5.58 cm, 1.66 cm respectively), intermediate (4.58 cm, 1.45 cm respectively) and male (4.55 cm, 1.47 cm respectively) flowers. The application of GA3 30 ppm resulted in maximum number of male flowers (75.66). Hence, it is not considered as a better treatment. Application of NAA 40 ppm at full bloom stage registered minimum days taken for fruit set (37.55 days) and recorded maximum number of fruits (62.44/plant), yield per plant (16.45 kg/plant) and yield per hectare (15232.70kg). However, fruit length (8.66 cm), fruit diameter (8.71 cm), fruit weight (262.23 g), fruit volume (255.44 ml), aril weight (188.90 g), aril per cent (72.03), minimum number of seeds (269.60) and seed weight (3.09 g) were also recorded. The quality parameters such as total soluble solids (16.76˚B), reducing sugars (13.83%), non-reducing sugars (1.75%) and total sugars (15.58%) were found highest, besides, the minimum physiological loss in weight (26.17%), with highest shelf life (29.00 days). The present findings can be commercially used in making pomegranate production more profitable (1:3.90) by the application of Ethrel 250 ppm and NAA 40 ppm in Bhagwa variety of pomegranate.

The experiment was laid out in randomized block design with 13 treatments and 3 replications. Among the different treatments the foliar application of GA3 150 ppm + NAA 300 ppm recorded the highest fruit volume (147.67 ml), fruit length (6.45 cm), fruit diameter (6.59 cm), weight of fruit (152.33 g), pulp weight (147.70 g), pulp per cent (96.96), number of fruits per tree (378.00), yield per tree (57.63 kg)and yield per hectare (23.05 tonnes) whereas, the quality parameters like TSS (11.79 0Brix), ascorbic acid (143.99 mg/100 g pulp), titratable acidity (0.37 %), TSS : acid ratio (31.96), reducing sugar (4.23 %), non-reducing (2.67 %) and total sugars (6.89 %) while, minimum yield (41.00 kg) and yield parameters were recorded in control. The foliar application of GA3 100 ppm + NAA 200 ppm recorded lowest number of seeds per fruit (244.33) and seed weight per fruit (4.38 g), while maximum number of seeds per fruit (321.67) and seed weight per fruit (5.36g) was recorded in control. The application of CCC 750 ppm has registered better quality parameters such as lowest physiological loss in weight (6.59 %) and maximum shelf life (11.67 days), whereas highest physiological loss in weight (10.16 %) and minimum shelf life (7.00 days) was recorded in control.
