×<p class="MsoNormal" xss=removed><span lang="IN" xss=removed>Garlic is a commodity
crop that has a high economic value so that it has an attraction to
cultivation. the decline in garlic production is caused by problems often faced
by farmers, namely the decline in chemical, biological, and physical properties
of the soil resulting in non-optimal garlic growth. This study aims to
determine the effect and find the concentration of GA<sub>3</sub> and the dose
of silica fertilizer on the growth and yield of garlic. The research was
conducted in Dukuh Pancot, Kalisoro Village, Tawangmangu District, Karanganyar
Regency, Central Java as garlic cultivation; Soil Chemistry and Fertility
Laboratory, Faculty of Agriculture, Sebelas Maret University for soil analysis
and Crop Production Management Ecology Laboratory, Faculty of Agriculture, </span><strong><span lang="EN-GB" xss=removed>Sebelas Maret</span></strong><span lang="EN-US" xss=removed> University</span><span lang="IN" xss=removed> for garlic
yield measurement from </span><span lang="IN" xss=removed>May-September

The method used was a factorial Randomized Complete Group Design with two
factor and three replications. The first factor was GA<sub>3 </sub>(0, 60, and 120
ppm). The second factor was silica fertilizer (0, 15, and 30 mL). Variables
observed included environment (soil, air temperature, air humidity, light
intensity, and rainfall), growth (plant height, number of leaves per clump,
fresh weight of stover, and dry weight of stover) and yield (</span><span lang="EN-US" xss=removed>bulb</span><span lang="IN" xss=removed> diameter, number of
cloves, fresh weight of </span><span lang="EN-US" xss=removed>bulb</span><span lang="IN" xss=removed> per clump, dry weight productivity of </span><span lang="EN-US" xss=removed>bulb</span><span lang="IN" xss=removed> per ha). Environmental
data (air temperature, air humidity, rainfall, and light intensity) and
preliminary soil analysis were analysed descriptively. Garlic growth and yield
data were analysed using Analysis of Variant (ANOVA) at the 95% significance
level to obtain the effect of all observation variables. If the results showed
an effect, orthogonal polynomial regression was tested to find the optimum
concentration of GA3 and dose of silica fertiliser. The results showed that GA<sub>3</sub>
and silica fertilizer had an interaction on the fresh weight of garlic stems
with the optimum concentration without the use of GA<sub>3</sub> and 5.01 mL
silica fertilizer. GA<sub>3</sub> concentration of 120 ppm can increase the
number of garlic leaves. The optimum dose of 18.50 mL silica fertilizer tends
to increase the height of garlic plants. <o></o></span></p>
