The results indicated that dolomite significantly influenced shallot growth and yield, particularly affecting bulb diameter, bulb count per plant, fresh bulb weight per plant, and dry bulb weight per plant and plot.
It also significantly impacted bulb count per plot.
Chicken manure notably influenced dry bulb weight per plot and significantly affected plant height, dry stalk weight per plant, bulb diameter, fresh bulb weight per plant, and dry bulb weight per plant.
The interaction between dolomite and chicken manure significantly impacted fresh stalk weight per plant, dry bulb weight per plant and plot, bulb diameter, and bulb count.
The highest yield was observed in the D2F3 combination, with a dry bulb weight per plot of 1441.

The use of dolomite and chicken manure singly or in combination has a positive impact on the growth and yield of tubers, so it can be concluded that administering these two types of ameliorant simultaneously is more effective in increasing plant productivity than single treatment.
It is recommended that the combination of dolomite and chicken manure be applied optimally in shallot cultivation to increase yields and quality of bulbs.
Its use needs to be adjusted to soil conditions and plant needs to support better growth and productivity.

The plants whose bulbs are used are used as kitchen spices and medicine.
The need for shallots continues to increase along with the increasing population of Indonesia.
Developing shallot production and increasing productivity in production centers is important considering the increasing consumer demand along with population growth and increasing purchasing power.
Based on data from the National Food Agency (Bapana.
, the need for shallots for household consumption in Indonesia in 2023 is 797.
thousand tons.
This number has decreased by 4.
4% compared to 2022.
However, when compared to the previous five years, this figure is still slightly higher.
For national shallot production in 2023, it is estimated to reach 2.
14 million tons.
This amount has increased 15% or equivalent to 161.
62 thousand tons compared to 2022.
With a production of 14 million tons, after deducting the amount that is left over, use for seeds, food and beverage needs, industrial raw materials, and direct consumption, and taking into account imports and exports, there will be a surplus of around 844.
46 thousand tons (Pertanian.
Increasing the efficiency of shallots must also be supported by the quality of the seeds used, because the growth and yield of shallots are not stopped by the bulbs used as Differences in seed size may make a difference in the initial growth of the plant, large seeds certainly have more food reserves, so that sufficient energy is available for better growth, but on the other hand, this will affect how much production costs will be incurred to secure the seeds (Armaini et al.
, 2.
According to data from the Ministry of Agriculture .
Indonesia ranks third as a country importing shallots in the ASEAN region, with an average import of 89 thousand tons per year.
In the 2017-2018 period.
Thailand was the main supplier with the highest import volume, reaching 28.
06%, and an average price of 631 USD per ton.
The high demand for shallots, which have great economic value, has driven increased In 2023, shallot production in Indonesia is estimated to reach 2.
14 million tons, an increase of around 8.
15% compared to the previous year.
This increase in production was supported by an increase in harvested area of 7.
88% to 199.
57 thousand hectares, as well as an increase in productivity of 0.
22% to 10.
74 tons per hectare.
However, in some areas, there has been a decrease in the area of shallot land.
For example, in Brebes Regency, which is one of the largest centers of shallot production in Indonesia, the planting area and harvested area have decreased due to the impact of climate change and long droughts.
In 2023, the planted area was recorded at 26,331 hectares with a harvested area of 24,182 hectares, a decrease compared to the previous year which had a planted area of 30,757 hectares and a harvested area of 32,571 hectares (Palupi & Widyasunu, 2.
Lime and manure are given to plants to help their growth by making them taller and having more branches.
The experimental soil used is ultisol which has a low pH and low natural material content.
The provision of dolomite will increase the soil pH to neutral so that it will increase the availability of nutrients needed by plants, especially Phosphorus is an important component in the cell metabolism cycle.
The availability of phosphorus will affect the consumption of other large and small scale basic Manure plays a role in increasing the natural material content of the soil, increasing the nitrogen content, and then developing the soil structure so that the soil becomes more fertile (Buhaira & Akmal, 2.
Manure has advantages compared to inorganic compost.
The advantage of organic compost is that it is less harmful to the ecosystem and safe when applied to the soil.
Chemical residues that can harm the soil ecosystem, including soil organisms.

groundwater, air, and their impact on humans, are not found in organic fertilizers.
Compost is one of the natural fertilizers that can be used by farmers.
Compost is manure that comes from various types of animal waste that contains various nutrients for plants, both small-scale and full-scale supplements.
Fertilizers that can be used by farmers are cow compost, chicken manure, pig manure, goat compost and various types of manure (Baka et al.
, 2.
Compost from chicken manure has superior quality when compared to regular manure and artificial compost.
This advantage is seen from its ability to increase the humus content which is rich in natural ingredients important for plants, provide complete nutrients on a large and small scale, and help increase water retention in the soil so that plant roots can absorb water and nutrients more efficiently.
In addition, chicken compost contains active microorganisms that are able to decompose natural ingredients in the soil into useful humus, while improving the physical structure of the soil to support long-term In addition, the availability of chicken compost is very abundant thanks to the large amount of waste from the chicken farming industry which continues to grow, especially for meat and egg production.
Chicken manure is also an ideal material to be processed into natural fertilizer that supports sustainable agricultural practices (Ifadah et , 2.
Although shallot production in Indonesia continues to increase, there are still challenges in maintaining productivity in various regions, especially due to climate change, limited land, and low soil fertility as in Brebes Regency.
Ultisol soil with low pH and minimal organic matter content is one of the main obstacles in shallot cultivation, so efforts are needed to improve soil quality by providing dolomite and chicken manure.
Dolomite plays a role in increasing soil pH and phosphorus availability, while chicken manure can increase organic matter content and soil fertility.
However, further research is still needed on the effectiveness of the combination of dolomite and chicken manure in increasing the growth and yield of shallots optimally.
Therefore, this study aims to evaluate the effect of dolomite and chicken manure on the growth and yield of shallots, as well as to determine the best combination that can increase plant productivity in ultisol Method Place and Time of Research This research was conducted from August 17 to October 20, 2023 in Bangsalan Village.

Dolomite treatment had a significant effect on the parameter of the number of tubers per plot and dolomite treatment had no significant effect on the parameters of plant height, number of leaves, fresh stover per plant, dry stover per plant.
The treatment of chicken manure had a very significant effect on the parameters of dry consumption tuber weight per plot.
The treatment of chicken manure had a significant effect on the parameters of plant height, dry stover per plant, tuber diameter, fresh tuber weight per plant, dry consumption tuber weight.
Chicken manure treatment did not significantly affect the parameters of number of leaves, fresh stover per plant, number of tubers per plant, number of tubers per plot.
The combination of dolomite and chicken manure treatment had a very significant effect on the parameters of fresh stover per plant, weight of dry bulbs consumed and weight of dry bulbs consumed per plot.
The combination of dolomite and chicken manure treatment had a significant effect on the parameters of tuber diameter, number of tubers per plant, number of tubers per plot.
The combination of dolomite and chicken manure treatment did not significantly affect the parameters of plant height, number of leaves, dry stover per plant, fresh tuber weight per plant.
The combination of dolomite treatment and chicken manure produces a strong synergy in improving soil quality and supporting plant growth.
Chicken manure as an organic fertiliser functions to add organic matter, improve soil structure, and increase the soil's ability to retain water.
In addition, chicken manure encourages soil biological activity and increases cation exchange capacity (CEC), which in turn helps maintain the availability of essential nutrients such as N.
S, and micronutrients through gradual The N content in chicken manure plays an important role in the synthesis of amino acids and proteins that are essential for plant growth.
Meanwhile, the application of dolomite plays a role in increasing the magnesium (M.
and calcium (C.
content in the soil, as well as raising the pH of slightly acidic soil.
With increased Mg levels, plants can absorb these nutrients more effectively, supporting optimal growth.
Liming with dolomite also serves to lower exchangeable aluminium levels, providing additional benefits to plants through neutralisation of aluminium which is detrimental in acid soils.
The combination of chicken manure and dolomite provides a complementary effect, where dolomite helps maintain soil pH balance and increases Mg availability, while chicken manure adds other nutrients and improves soil structure, creating ideal conditions for plant growth (Putra & Hanum, 2.

Effect of Dolomite Application on the Growth of Red Onion (Allium ascalonicum L.
The dolomite treatment (D) had no significant effect on the height of shallot plants (Allium ascanolicum L.
), due to neutral soil conditions, so that the addition of dolomite was less effective in increasing nutrient availability.
The dolomite treatment (D) had no significant effect on the number of leaves of shallot plants (Allium ascanolicum L.
), due to neutral soil conditions, so the addition of dolomite is less effective in increasing microbiological activity and the availability of essential nutrients for plants.
The treatment of chicken manure (F) had no significant effect on the growth parameters of the number of leaves of shallot plants (Allium ascanolicum L.
The treatment of dolomite dose (D) had no significant effect on fresh yield per clump of shallot (Allium ascanolicum L.
), due to the relatively fertile soil conditions and good nutritional balance, so that additional magnesium through dolomite was no longer a dominant factor in the process of photosynthesis and plant tissue formation.
In addition, the genetic variability of shallot plants themselves may also affect the response to dolomite treatment, making the results less specific and insignificant.
As a result.
JRUCS : Journal of Rural and Urban Community Studies Effect of Dolomite Dosage and Chicken Manure on the Growth and Yield of Red Onions (Allium ascanolicum L.
dolomite treatment did not increase the economic or qualitative value of fresh yield per shallot plant.
The treatment of dolomite dose (D) had no significant effect on dry stover per clump of shallot (Allium ascanolicum L.
The dolomite treatment did not show a significant effect on dry stover per clump of shallot because the dose applied was not sufficient to significantly increase nutrient availability.
In addition, environmental factors such as soil moisture and interaction with other fertilisers can affect the effectiveness of With optimal soil conditions, the addition of dolomite did not have a significant impact on dry stover growth, so the results had no significant effect.
Effect of Chicken Manure on the Growth of Red Onion (Allium ascalonicum L.
The treatment of dolomite dose (D) had no significant effect on dry stover per clump of shallot (Allium ascanolicum L.
The treatment of dolomite dose did not show a significant effect on dry stover per clump of shallot because the dose applied may not be sufficient to significantly increase nutrient availability.
In addition, environmental factors such as soil moisture and interaction with other fertilisers may affect the effectiveness of With optimal soil conditions, the addition of dolomite did not have a significant impact on dry stover growth, so the results had no significant effect.
The treatment of chicken manure (F) significantly affects the height of shallot plants (Allium ascanolicum L.
The highest F2 treatment reached 30.
20 cm, significantly influenced by F0 treatment reached 28.
04 cm.
F1 reached 29.
90 cm, and F3 reached 28.
The highest treatment of 10 tonnes/ha chicken manure (F.
was caused by chicken manure improving soil physical properties such as structure, permeability, pores, consistency, and soil temperature.
The hygroscopic nature of organic matter in the fertiliser makes the soil more moist and cooler, encourages microorganism activity and increases the number of soil pores, improves permeability, consistency, and soil chemical properties, including increased organic matter content, nutrients, and cation exchange capacity (Susikawati et al.
, 2.
The DMRT test results show that the F2 treatment has the highest average shallot plant height .
60 c.
and is significantly different from all other treatments.
F1 treatment .
70 c.
was not significantly different from F2 but significantly different from F0 .
and F3.
Treatment F0 .
13 c.
and F3 .
had a lower average and showed no significant difference from each other.
F3 highest manure treatment was in the F2 treatment, which is 10 tonnes/ha chicken manure.
Chicken manure can supply sufficient nutrients to support plant height growth.
This is due to the higher nutrient content in chicken manure compared to other types of manure (Harbing et al.
, 2.
The chicken manure treatment had no significant effect on the number of shallot leaves, due to the increase in macronutrients such as nitrogen (N), phosphorus (P), and potassium (K) in the soil due to the application of chicken manure.
Although nitrogen is important for vegetative growth such as leaves, stems, and roots, hot and sunny dry climate factors strongly favour the growth of shallot leaf number.
Shallot plants require an optimum air temperature between 25-32AC, with the ideal temperature around 30AC (Susikawati et al.
, 2.
The treatment of chicken manure (F) had no significant effect on fresh yield per onion plant (Allium ascanolicum L.
), due to the fact that chicken manure is rich in nutrients, the dose applied may not be sufficient to have a significant impact on fresh yield growth.
In addition, factors such as soil conditions, moisture, and interaction with other nutrients in the soil can also affect the effectiveness of chicken manure in supporting JRUCS : Journal of Rural and Urban Community Studies Effect of Dolomite Dosage and Chicken Manure on the Growth and Yield of Red Onions (Allium ascanolicum L.
plant growth.
In addition, if the shallot plants are already getting sufficient nutrients from other sources, then the addition of chicken manure will not provide a significant increase.
The acquisition of chicken manure treatment (F) has a significant effect on dry stover per clump of shallots (Allium ascanolicum L.
The highest treatment of F3 reached 31 g, significantly influenced by the treatment of F0 reached 2.
86 g.
F1 reached 3.
76 g, and F2 reached 3.
41 g.
The highest treatment of chicken manure 10 tonnes/ha (F.
was the highest.
The treatment of 10 tonnes/ha chicken manure (F.
was the highest, this was due to the application of organic fertiliser, such as chicken manure, takes time to be absorbed and utilised effectively by plants due to its low nutrient content and slow release.
In general, the effectiveness of organic fertilisers is highly dependent on soil characteristics and the dose applied.
Nutrients absorbed by plants support metabolic processes and maintain their physiological functions.
Therefore, the proper use of chicken manure can have a significant effect on increasing dry stover per onion sample (Jahung et al.
, 2.
The DMRT test results show that the treatment of chicken manure has a significant effect on dry stover per clump of shallots.
The F3 treatment had the highest average .
and was significantly different from all other treatments.
Meanwhile, treatments F0.
F2, and F1 showed no significant difference from each other, with a lower average than F3.
This occurred because plant growth continued to increase along with the application of large amounts of chicken manure, which was able to meet the nutrient needs of plants.
The higher the dose of chicken manure applied, the better the plant growth, which in turn has a positive impact on increasing production.
Application of chicken manure also supports shallot growth by enhancing physiological processes in plant tissues.
This process allows photosynthetic products to be effectively translocated into the bulbs, supporting optimal bulb formation and development (Wuriesyliane et al.
Effect of Treatment Combination on the Growth of Red Onion (Allium ascalonicum The combination of dolomite dose (D) and chicken manure (F) did not significantly affect the height of shallot plants (Allium ascanolicum L.
), due to environmental factors such as soil moisture and temperature that affect the effectiveness of this treatment combination.
The combination of dolomite dose (D) and chicken manure (F) did not significantly affect the number of leaves of shallot plants (Allium ascanolicum L.
), due to the nutrient content of chicken manure is sufficient to support growth, so the addition of dolomite does not have a significant effect in affecting the final result of growth.
The combination of dolomite dose (D) and chicken manure (F) had a very significant effect on fresh fruit per clump of shallot (Allium ascanolicum L.
The highest D2F3 treatment reached 16.
13 g.
The combination of 10 tonnes/ha dolomite and 15 tonnes/ha chicken manure (D2F.
treatment showed the highest yield, due to the provision of dolomite, which is able to raise soil pH and provide essential nutrients for plants.
Dolomite also contains various cations and other useful micro elements, thus supporting the growth and development process of shallot plants.
By increasing the soil pH, dolomite improves soil conditions that allow for more optimal nutrient absorption by plant roots.
In addition, the microelements contained in dolomite help strengthen plants, accelerate metabolic processes, and improve soil structure, all of which contribute to healthier and more productive plant growth.
Regular use of dolomite can also increase the resilience of shallot plants to less-than-optimal environmental conditions, such as acidic or less fertile soils (Ilham et al.
, 2.
The use of organic fertilisers such as chicken manure is beneficial for increasing soil humus content, improving soil structure, and activating JRUCS : Journal of Rural and Urban Community Studies Effect of Dolomite Dosage and Chicken Manure on the Growth and Yield of Red Onions (Allium ascanolicum L.
microorganisms in the soil so that the balance of nutrients in the soil becomes more In addition, it helps neutralise soil pH, increase soil binding capacity to nutrients, and improve air circulation in the soil (Sutikarini et al.
, 2.
The results of the DMRT test showed that the combination of dolomite and chicken manure treatments had a very significant effect on fresh fruit per clump of shallots.
The D2F3 treatment had the highest average .
and was significantly different from all other treatments.
Treatments D0F2 to D1F3 had a lower average fresh yield than D2F3 but significantly different from groups D0F0 to D2F2, which had a lower average and showed no significant difference from each The treatment combination of D2 .

and F3 .

showed significant potential in increasing shallot growth and production, especially on peat soils.
The application of dolomite at 10 tonnes/ha acts as an effective ameliorant to increase soil pH, creating optimal conditions for shallot bulb This increase in pH not only supports the absorption of nutrients such as potassium (K), calcium (C.
and magnesium (M.
, but also accelerates the decomposition of organic matter through increased activity of soil microorganisms.
This makes nutrients more quickly available to plants, so that shallot growth can be maximised (Ilham et al.
, 2.
Meanwhile, the application of chicken manure at a dose of 15 tonnes/ha supplements the macronutrients such as nitrogen, phosphorus and potassium needed for bulb formation and development.
Phosphorus, as one of the elements contained in chicken manure, plays a vital role in the bulb formation process of shallots, which are high phosphorus-absorbing plants (Jali et al.
, 2.
The result of the combination of dolomite dose (D) and chicken manure (F) had no significant effect on dry stover per clump of shallot (Allium ascanolicum L.
), that other factors may be more dominant in affecting plant growth, thus the need for further research to understand the interaction between dolomite and overall shallot growth conditions.
This indicates that other factors, such as soil conditions and cultivation techniques, may have a more dominant role in influencing shallot growth than the type of chicken manure Yield Parameters of Red Onion (Allium ascalonicum L.
To determine the effect of dosing dolomite and chicken manure on the growth of shallot plants (Allium ascanolicum L.
), the variance test was conducted and presented in Table Meanwhile, to determine the effect of the treatment level of dolomite dosing and chicken manure on the yield of shallot plants (Allium ascanolicum L.

The use of dolomite, which is rich in magnesium (M.
and calcium (C.
, can increase the pH of acidic soil, thus improving soil structure and fertility.
Dolomite helps neutralise acidity and increases the availability of essential nutrients such as phosphorus (P) which plays a role in tuber enlargement.
With healthier soil and more available nutrients, the diameter of onion bulbs tends to increase, producing onions with larger size and better quality (Manurung & Vindo, 2.

The D1 treatment has a higher average than D0, but both do not show significant differences from each other.
Onion bulb formation is strongly influenced by the increase in soil pH and nutrient availability resulting from the application of 10 tonnes/ha of dolomite.
Dolomite provides potassium element which plays an important role in supporting the bulb formation process.
Increasing the dolomite dose increases the availability of essential nutrients for plants, including potassium, which plays a role in increasing photosynthetic activity.
Higher photosynthetic activity results in the accumulation of photosynthate that can be translocated to generative organs, especially shallot bulbs.
With the increase in assimilate material produced, the process of bulb enlargement and filling becomes more optimal, producing high quality shallots (Delina et al.
, 2.
