Impact of sulphur, boron and its combinations on growth and yield of onion (Allium cepa L.)

Abstract

The investigation was conducted during Rabi seasons of 2017-18 at the horticulture farm nursery, College of Agriculture, Gwalior. The study involve Sixteen treatment combinations consisting of four sulphur levels viz. S0: Control, S1: 20 kg S ha-1, S2: 40 kg S ha-1, S3: 60 kg S ha-1 and four doses of Boron, i.e. B0: Control, B1: 0.5 kg B ha-1, B2: 1.0 kg B ha-1 and B3: 2.0 kg B ha-1 in factorial randomized block design with three replications. The recommended dose of fertilizer (RDF) adopted was 100:60: 80 kg of N: P: K ha-1. The increasing level of sulphur and boron up to 60 kg ha-1 and 2.0 kg B ha-1 increased growth and bulb yield significantly over control respectively.
