The effect of different planting schemes on onion yield under intercropping conditions

Abstract

This article presents the results of studying the effect of different planting schemes on onion yield under intercropping conditions. The experiments were conducted during 2021-2023, and the influence of row spacing and plant spacing on total and marketable yield was evaluated. The results showed that the planting scheme of (40+15+15)/3 × 7.5 cm provided the highest average total yield of 47.3 t/ha and marketable yield of 43.2 t/ha. The highest share of marketable yield relative to total yield was recorded in the (50+20)/2 × 10 cm treatment, reaching 93.5%. The findings indicate that selecting an optimal planting scheme is essential for obtaining high and marketable onion yields under intercropping conditions.
