Intra Row Spacing Effect on Growth and Yield Performance of Garlic (Allium sativum L.) at Wolkite University, Gurage Zone, Central Ethiopia

Garlic (Allium sativum L.) is one of the most important vegetable crops produced in Ethiopia including Gurage zone. Use of appropriate plant spacing’s is a major agronomic practice to improve the productivity and quality of garlic. However, farmers are producing the crop without appropriate plant spacing; due to this the productivity of the crop in the zone is far below its potential including other factors. Cognizant of this, the present experiment was initiated and conducted with the objective of determining the ideal intra row spacing for growth and yield component of garlic, a field experiment was carried out at the experimental site of Wolkite University, located at Cheha district, Gurage zone of South Nation and Nationality of People Region, throughout the entire 2019 growing season using supplemental irrigation. The experiment used a randomized complete block design (RCBD) with four treatments of 6cm, 8cm, 10cm, and 12cm between plants, and three replications. Garlic plant height, leaf length, leaf width, leaf number, and fresh and dry biomass yield were all examined attributes, and the analysis of variance revealed that intra row spacing significantly affected all of the tested parameters. Maximum plant height (48.91cm) and leaf length (43.75cm) were recorded from 30cm by 6cm plant spacing, while maximum leaf width (10.6cm), leaf number per plant (10.53), fresh yield biomass (166.74g), and dry biomass (38.59g) were obtained from 30cm by 12cm plant spacing. The wider the plant spacing the higher were the leaf number, leaf width, and fresh and dry biomass yield but plant height and leaf length were decreased. Therefore, based on these results mostly bulb a yield of garlic was positively correlated with the better performance of the parameters were the plant spacing became increased, hence it can suggest bulb yield of garlic increased were the spacing between plants were increased. The results of this experiment should be confirmed by a similar investigation that includes yield components in the study area.
