Abstract

Application of nutrients through soil is not an effective method. So, the alternative approach to overcome the problem of ineffective fertilizer nutrient supply. These unpredicted challenges urge the adoption of novel and resource efficient stratagies to stepping out of the growth and yield parameters. The present study was undertaken to evaluate performance of strawberry as influenced by humic acid and water soluble fertilizers on growth under naturally ventilated polyhouse. The study was made during 2017-18 with completely randomised design by taking fourteen treatments replicated thrice. The results promulgated that application of 100 % RDF through soil along with foliar application of humic acid (2%) + 19:19:19 (1%) + potassium nitrate (1%) recorded significantly highest plant height per plant (33.03 cm), trifoliate leaves per plant (32.32), crowns per plant (5.75), Runners per plant (2.02), plant spread of 46.61 and 44.50 cm North-south and east-west respectively. Leaf area (176.86 cm2), leaf area index (1.89) plant dry weight at harvest (30.29g/plant), total Chlorophyll content of leaves (2.44 mg/g of fresh weight), yield per plot (4.55 kg) followed by application of 75% RDF through soil along with foliar application of humic acid (2%) + 19:19:19 (1%) + potassium nitrate (1%).

Conclusion

On the basis of results obtained in the present investigation, it can be concluded that application of 100 % RDF + HA (2%) + 19:19:19 (1%) KNO3 (1%) through foliar application or else 75 % RDF + HA (2%) + 19:19:19 (1%) + KNO3 (1%) through foliar application at 45, 60 and 75 days after planting showed promising results with respect to growth and yield parameters.
