Effect of foliar application of water soluble fertilizer, sulphur, zinc and boron on growth, yield and economics of garlic (Allium sativum L.) in a vertisol

Abstract

A field experiment was conducted to study the effect of foliar application of water soluble fertilizer, sulphur, zinc and boron on growth, yield and economics of Garlic (Allium sativum L.) in a Vertisol during rabi 2022-2023 at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The experiment was laid out in randomized complete block design with eight treatments comprising foliar spray of 19:19:19 @ 1% at 30 days after sowing, foliar spray of zinc sulphate @ 0.50% and borax @ 0.25% both at 45 and 60 days after sowing individually and in combination replicated thrice. Results revealed that foliar spray of 19:19:19 @ 1% at 30 days after sowing + zinc sulphate @ 0.50% + borax @ 0.25% both at 45 and 60 days after sowing along with RPP significantly increased the plant height (49.50 cm), number of leaves per plant (8.22), equatorial (4.48 cm) and polar (4.17 cm) diameter of bulb, number of cloves per bulb (12.14), clove length (2.49 cm) and total bulb yield (90.60 q ha-1) of garlic with higher B:C ratio (3.61).
