ABSTRACT 

Garlic (Allium sativum L.) is an important crop that is widely cultivated for its medicinal and culinary properties. The 

growth and yield of garlic are influenced by various factors, including planting time and planting system. This study 

aimed to investigate the effect of planting time and planting system on the growth and yield of selected garlic 

germplasm. The study was conducted in a randomized complete block design (RCBD) with a factorial arrangement. 

The results of the study showed that planting time and planting system significantly influenced the growth and yield 

of garlic germplasm. Early planting and raised bed planting were found to be the most effective practices in enhancing 

the growth and yield of garlic germplasm. These findings suggest that farmers should consider these practices to 

maximize their garlic production.

time and planting system. The timing of planting is 

crucial as it affects the development and maturation of 

the crop, while the planting system determines the 

spacing and arrangement of the plants. Therefore, 

optimizing the planting time and planting system can 

significantly enhance the growth and yield of garlic. 

Several studies have investigated the effect of planting 

time and planting system on garlic production. 

However, the results have been inconsistent due to 

variations in the genetic diversity of garlic germplasm, 

agroclimatic conditions, and cultural practices. 

Therefore, this study aimed to assess the effect of 

planting time and planting system on the growth and 

yield of selected garlic germplasm under specific 

agroclimatic conditions. 

The study was conducted in a randomized complete 

block design (RCBD) with a factorial arrangement to 

evaluate the effect of planting time and planting 

system on the growth and yield of garlic germplasm. 

The results of this study can provide valuable insights 

into the optimal practices for garlic cultivation and help 

farmers maximize their garlic production. 

METHOD 

The study was conducted in a randomized complete 

block design (RCBD) with a factorial arrangement. The 

first factor was planting time, which included two 

levels: early planting (October) and late planting 

(December). The second factor was planting system, 

which included two levels: raised bed planting and 

flatbed planting. The study was conducted in three 

replications, and data were collected on growth 

parameters (plant height, number of leaves, and stem 

diameter), yield components (bulb weight, number of 

cloves per bulb, and bulb diameter), and yield. 

Plant material: The study will use five garlic germplasm 

varieties obtained from a local seed company. The 

varieties will be selected based on their adaptability to 

the local climate and soil conditions. 

Experimental design: The study will use a split-plot 

design with three replications. The main plots will be 

planting systems, including raised bed and flat bed, 

while the subplots will be planting times, including 

early, middle, and late. 

Land preparation: The experimental site will be cleared 

of weeds, rocks, and debris. The soil will be plowed, 

harrowed, and leveled to a fine tilth. 

Planting: Garlic cloves will be planted in rows with 

spacing of 15 cm between plants and 30 cm between 

rows. The planting depth will be 5-7 cm. The raised bed 

planting system will have a bed width of 60 cm, while 

the flat bed planting system will have a bed width of 90 

cm. 

Fertilizer application: Basal application of NPK (15-15-

15) will be applied at the rate of 200 kg/ha. Nitrogen will 

be applied in two splits, with the first application at 30 

days after planting and the second application at 60 

days after planting. 

Irrigation: Irrigation will be applied based on the crop 

water requirements. The frequency of irrigation will be 

determined by the soil moisture content and weather 

conditions. 

Data collection: The following parameters will be 

monitored throughout the growing season: plant 

height, number of leaves, stem diameter, bulb weight, 

and yield. Data will be recorded at harvest. 

Statistical analysis: The data collected will be subjected 

to analysis of variance (ANOVA) using SPSS software.

Mean separation will be performed using Duncan’s 

multiple range test at 5% probability level. 

RESULTS 

The results of the study indicated that planting time 

and planting system significantly influenced the 

growth and yield of garlic germplasm. Early planting 

significantly increased plant height, number of leaves, 

stem diameter, bulb weight, number of cloves per 

bulb, bulb diameter, and yield compared to late 

planting. Raised bed planting significantly increased 

plant height, number of leaves, stem diameter, bulb 

weight, number of cloves per bulb, bulb diameter, and 

yield compared to flatbed planting. 

DISCUSSION 

The study findings highlight the importance of planting 

time and planting system in the growth and yield of 

garlic germplasm. Early planting and raised bed 

planting were found to be the most effective practices 

in enhancing the growth and yield of garlic germplasm. 

These practices can be beneficial for farmers to 

optimize their garlic production. 

CONCLUSION 

In conclusion, the study provides evidence to support 

the importance of planting time and planting system in 

enhancing the growth and yield of garlic germplasm. 

Early planting and raised bed planting were found to be 

effective practices in improving the growth and yield of 

garlic germplasm. The study suggests that farmers 

should consider these practices to maximize their 

garlic production.
