Abstract:
The field experiment was carried out at Department of Horticulture, National Post Graduate College, Barhalganj, Gorakhpur, U.P., India during 2019-20 on strawberry plant cv. Sweet chaelie. The experiment was designed in RBD to study the effect of micronutrients viz. boron, zinc and molybdenum and its combination on plant growth pattern and yield attributing characters of the strawberry. Boric acid (H₃BO₃) (0.2% & 0.4%), zinc sulphate (ZnSO₄) (0.2% & 0.4%) and sodium molybdate (Na₂MoO₄) (0.2% & 0.4%) were used as a source of boron, zinc and molybdenum respectively. All the plants fertilized with recommended dose of NPK (150:100:120 as N, P₂O₅ and K₂O). The spraying was done twice; during last week of November at after crown development stage and again at 30 days after the first spraying during years in three replication. Result proved that foliar spraying on strawberry plant with RDF + Zn + Mo + B + @ (0.4%) was the promising treatment for improvement of Plant height, Number of leaves, Plant spread (cm) at harvest, Days to first flowering (days), Days to First harvesting (days), Number of flower per plant, Number of fruit per plant, fruit Yield per plant (g), fruit Yield per plot (kg) and fruit Yield per ha (tn). This treatment was also found best for maximum Fruit length (cm), Fruit diameter (cm), Average Fruit Weight (g), as well as the cost benefit ratio.
