Abstract

This study aims to determine the type of mulch and dose of NPK fertilizer that can increase the growth and yield of shallots (Allium ascalonicum L.). The research was conducted in Cibogo Village, Cirebon Regency, West Java. The location is located at an altitude of 30 meters above sea level (m asl), the rain type belongs to type C (slightly wet). The research was conducted from April to June 2021. This study was prepared based on Group Randomized Design (RAK) with 2 treatment factors and 3 repeats. The first factor is the type of mulch and the second factor is the application of NPK fertilizer. The results showed that the combination of rice straw mulch treatment with NPK fertilizer 300 kg / ha had a significant effect on growth components, namely plant height 28 HST, number of leaves aged 42 HST, and a real effect on yield components, namely tuber diameter, fresh weight of tubers per clump and per plot, dry weight of tubers per clump and per plot. The results also showed that the combination of rice straw mulch treatment with NPK doses of 300 kg/ha and 400 kg/ha gave a good average dry weight of tubers per hectare, namely 8.4 tons/ha and 7.9 tons/ha, respectively.

Abstract

Papaya is in great demand by the public because of its sweet taste and abundant vitamin and mineral content. The problem is that in recent years papaya productivity has fluctuated due to poor soil structure and lack of nutrients in the soil, which results in poor seed growth and unqualified seedlings, so efforts need to be made to find the right type of planting media to support papaya nurseries, one of which is with vermicompost fertilizer. This experiment aims to determine the effect of the proportion of vermicompost fertilizer in the planting medium on the growth of china cultivar papaya seedlings. The research method used was a completely randomized design with six treatments consisting of K0 = 100% soil and 0% vermicompost fertilizer (control), K1 = 80% soil and 60% vermicompost fertilizer, K2 = 60% soil and 40% vermicompost fertilizer, K3 = 40% soil and 60% vermicompost fertilizer, K4 = 20% soil and 80% vermicompost fertilizer and K5 = 0% soil and 100% vermicompost fertilizer. The experimental results showed a significant effect on the proportion of vermicompost fertilizer on plant growth rate and root length of plants aged 15, 30, and 45 DAP, as well as root volume, stem diameter, plant height, number of leaves, fresh weight and dry weight of plants aged 30, 45 and 60 DAP but not significantly different from the observation of plant growth capacity aged 7 and 14 DAP.

Abstract

This study aims to determine the effect of the combination of concentration and time of spraying bioliquid organic fertilizer on the growth and yield of sweet corn plants (Zea mays Var. saccharata Sturt) Baruna variety. The research was conducted in Tegalsari Village, Plered District, Cirebon Regency from January to May 2023. The experimental method used was using the experimental method with Group Random Design (RAK), consisting of 7 treatment combinations and repeated 4 times. Data analysis was carried out using fingerprints and further tests with the Duncan Multiple Distance Test at the level of 5%. After that, a Correlation Test was carried out with Product Moment t Test analysis between the growth components and the yield of sweet corn plants. The results showed a real influence between the concentration and time of spraying bioliquid organic fertilizer on plant height, number of leaves aged 60 HST, stem diameter, length of husked cob, diameter of husked cob, weight of cob per plant, and weight of husked cob per plot. The concentration of liquid organic fertilizer 5 ml/1 liter of water and spraying time of 14, 28, 42 HST showed the best effect on the weight of cob per plot resulting in production of 15.60 kg/plot or equivalent to 17.33 tons/ha.

Abstract

This study aims to determine the effect of a combination of soaking time and seed location in the fruit on the early growth of California papaya cultivar plants. The study used an experimental method, the experiment was carried out in the Arjawinangun area, Cirebon Regency, from March to June 2023. Based on the results of the study on the effect of soaking time and seed location in the fruit on the growth of California papaya cultivar seedlings, the following conclusions can be drawn: the difference in the combination of soaking time and seed location in the fruit gives a difference to the initial growth variables, and good early growth of papaya plants is obtained from the combination of 24-hour soaking time and seed location at the base.

Abstract

Background. Red spinach growth and output can be increased through the use of organic and inorganic fertilizers. A liquid fertilizer created by fermenting organic materials, such as animal manure, serves as a practical option. Aims. The purpose of this research is to assess the effects of varying amounts of liquid organic fertilizer on the growth, yield, and potassium content of red spinach (Amaranthus tricolor L.). Research examining the use of liquid organic fertilizer on red spinach was conducted in cultivated fields located in Banjaran, within the Sumberjaya area of Majalengka. The experiment took place from April to June 2025. Methods. An experimental method was applied, utilizing a randomized block design (RBD) with six levels of fertilizer doses and four replicates each. Measurements included plant height, number of leaves, stem diameter, relative growth rate, fresh weight per plant and plot, as well as potassium content. The collected data were examined using a one-way analysis of variance (ANOVA). Subsequently, Duncan’s Multiple Range Test (DMRT) was applied to determine which treatments showed statistically significant differences. Conclusion. Findings show that different levels of liquid organic fertilizer have a significant impact on plant height, number of leaves, stem diameter, relative growth rate, fresh weight both per plant and per plot, as well as the potassium content within the plants. Implementation. Applying 150 mL of liquid organic fertilizer per plant yields the best results across all measured variables.

Abstract

This study aims to determine: (1) the effect of the combination treatment spacing and manure dosage on the growth and yield of sweet corn, (2) the best combination of spacing treatment and manure dosage on the growth and yield of sweet corn, and (3) correlation between growth components and yield of sweet corn plants. The experiment was carried out in Bakung Kidul Village, Jamblang District, Cirebon Regency from November 2022 to February 2023. The experimental method used was an experimental method using a Randomized Block Design (RBD) with a further test of the Scott Knott Cluster Test at a 5 percent significance level. It consisted of a combination of spacing and manure treatment, and was repeated three times. The treatment combinations were as follows: A (40 cm x 40 cm and 15 tons of manure/ha), B (40 cm x 40 cm and 20 tons of manure/ha), C (40 cm x 40 cm and 25 tons of fertilizer manure/ha), D (50 cm x 40 cm and 15 tons of manure/ha), E (50 cm x 40 cm and 20 tons of manure/ha), F (50 cm x 40 cm and 25 tons of manure/ ha), G (60 cm x 40 cm and 15 tons of manure/ha), H (60 cm x 40 cm and 20 tons of manure/ha) and I (60 cm x 40 cm and 25 tons of manure/ha). The results showed that: (1) the combination of spacing and manure treatment had a significant effect on the growth and yield of sweet corn, (2) a spacing of 50 cm x 40 cm combined with 20 tons of manure per hectare had the best effect on plant height, number of leaves, cob length, weight of cobs with and without husks per plot. Spacing of 50 cm x 40 cm combined with 20 and 25 tons of manure per hectare gave the best effect on cob diameter, cob weight with and without husks per plant, and (3) there was a significant positive relationship between plant height at 42 days old after planting, the number of leaves aged 28 days and 42 days after planting with cob weight without husk per plot.
