This study aimed to examine the effects of dolomite and phosphate fertilizers on the growth components, yield components, and overall yield of peanut plants (Hypoma 1 variety), to determine the optimal dolomite and phosphate combination for maximizing growth and yield, and to investigate the correlations between growth components, yield components, and final yield. The experiment was conducted from May to September 2022 at the Al-Zaytun Experimental Garden, Mekarjaya Village, Gantar Subdistrict, Indramayu Regency, West Java, at an altitude of 493 meters above sea level. The soil at the study site was classified as alluvial with a pH of 5.5 and a texture of sandy clay loam. The research employed a Randomized Complete Block Design (RCBD), consisting of 16 combinations of dolomite and phosphate fertilizers, each replicated twice, for a total of 32 plots. The treatments included combinations of dolomite at 0, 250, 500, and 750 kg/ha with phosphate at 75, 100, 125, and 150 kg/ha. The results indicated that different combinations of dolomite and phosphate significantly affected plant height at 28 days after sowing (DAS), number of leaves at 28 DAS, leaf area index at 28 DAS, number of branches at 21 and 28 DAS, root volume at 21 and 28 DAS, plant growth rate, number of pods per plant, number of filled pods per plant, wet and dry pod weight per plant, wet and dry pod weight per plot, and 100-seed dry weight. The highest dry pod yield was obtained from the combination of 500 kg/ha dolomite and 125 kg/ha phosphate (treatment K), which produced 2.54 kg/plot, equivalent to 3.39 t/ha on 80% of optimal land. However, the treatments did not significantly influence plant height at 14 and 21 DAS, number of leaves at 14 and 21 DAS, leaf area index at 14 and 21 DAS, number of branches at 14 and 21 DAS, root volume at 14 DAS, or the number of empty pods.

This study aimed to investigate the effects of compost and NPK fertilizers on the growth and yield of shallot plants (Allium ascalonicum L., Bima variety), to determine the optimal rates of compost and NPK for achieving high yields, and to examine the correlations between yield components and total yield. The experiment was carried out from June to August 2022 at the Agricultural Complex, Ma’had Al-Zaytun Campus, Indramayu, West Java, located at an altitude of approximately 50 meters above sea level. The soil at the site was classified as latosol with a pH of 5.5 and a clay texture (80.16%). The area has a Type C climate, characterized by moderately wet conditions, monthly rainfall ranging from 4 to 63.4 mm, and an average temperature of 32°C. The research used an experimental approach with a Randomized Complete Block Design (RCBD) in a factorial arrangement of nine treatment combinations of compost and NPK fertilizers. Compost was applied at three levels (1.5, 2, and 2.5 t/ha), while NPK was applied at three levels (150, 200, and 250 kg/ha). Each treatment was replicated three times, resulting in 27 plots, each measuring 3 m². The collected data were analyzed using analysis of variance (ANOVA) and Scott-Knott’s multiple comparison test, while correlations between growth components and yield were assessed using the Pearson Product Moment correlation. The highest dry bulb yield was obtained from the combination E (2 t/ha compost + 200 kg/ha NPK), producing 3.92 kg/plot, equivalent to 9.8 t/ha. Significant relationships were observed for root volume, plant growth rate, number of tillers, bulb diameter, fresh bulb weight per plant, fresh bulb weight per plot, dry bulb weight per plant, and dry bulb weight per plot, with a strong correlation between the number of tillers, number of bulbs, and dry bulb weight per plot.

This study aimed to determine the interaction effects of gibberellin concentrations and compost application on the growth and yield of the mung bean (Vigna radiata L.) variety Vima 4. The experiment was conducted from August to October 2021 at the Agricultural Complex of the Ma'had Al-Zaytun Campus, Mekarjaya Village, Gantar District, Indramayu Regency, West Java Province. The site is situated approximately 50 m above sea level, on Latosol–Regosol soils, under a Type D rainfall pattern. The research employed a factorial randomized block design (RBD) with three replications. The first factor was gibberellin concentration (5 ppm/plant, 10 ppm/plant, and 15 ppm/plant), while the second factor was compost dosage (10 tons/ha, 15 tons/ha, and 20 tons/ha). Data were analyzed using analysis of variance (ANOVA), followed by Duncan’s multiple range test, and correlation analysis was conducted using the product-moment correlation coefficient. Results showed that there was a significant interaction between gibberellin concentration and compost application on plant height and leaf area index (LAI). The treatment combination of 10 ppm gibberellin with 15 tons/ha compost yielded 0.67 kg of seeds per plot, which was not significantly different from other treatments. A significant positive correlation was observed between plant height and number of leaves at 35 days after planting (DAP) and between plant growth at 21 DAP with seed yield per plot. The correlation between plant growth traits and yield was categorized as moderate.
