Abstract

Cold lava floods contain volcano material that is rich in micronutrient which will gradually release through weathering process. The study of micronutrient elements affected by cold lava floods was conducted in Nagari Limo Kaum, Tanah Datar Regency, from October to March 2025. This research was aimed to assess and analyze the content of micronutrients (Fe, Mn, Cu, Zn, Mo and B) in land impacted by cold lava floods in Nagari Limo Kaum, Tanah Datar Regency. The study was carried out using a survey method. Soil samples were collected using purposive sampling from lava deposit (Locations 2, 3, and 4), areas affected by floodwater flow without deposition (Location 5), and unaffected areas (Location 1) as a comparison. Soil samples were collected from 0-20 cm soil depth at each location with 3 replicates. The analyzed parameters included soil pH, cation exchange capacity (CEC), exchangeable aluminum, and micronutrients (Fe, Mn, Cu, Zn, Mo and B). The results showed that increased the micronutrient content and exchangeable aluminium, increased while Zn and B content had low to very high criteria. The chemical properties especially pH and CEC of the soil  at L1 and L5, were lower that those at impacted soils.

Abstract

Cabbage (Brassica oleracea L.) is a high-value vegetable crop that requires balanced nutrient management to achieve optimal growth and yield. This study aimed to evaluate the agronomic and economic effectiveness of a compound fertilizer containing 21% N, 17% P₂O₅, and 17% K₂O on cabbage production. The experiment was conducted using a randomized complete block design with seven fertilization treatments, including a control, a reference NPK treatment, and five levels of compound fertilizer (0.5 to 1.5 recommended doses), each replicated four times. Observations included plant height, leaf number, yield per plant, yield per plot, and yield per hectare. Statistical analysis was performed using ANOVA and Duncan’s Multiple Range Test at a 5% significance level, while economic analysis was based on profit and benefit-cost ratio (R/C). The results showed that the 1.0 dose of compound fertilizer significantly improved plant height at 3 and 4 weeks after transplanting, increased leaf number at 5 weeks, and produced the highest yield per plant (1.92 kg), per plot (43.8 kg), and per hectare (17,500 kg). This treatment also demonstrated the highest relative agronomic effectiveness (139%) and economic viability, with an R/C ratio of 2.23 and a profit of IDR 14,487,900. Based on these findings, the recommended application rate for cabbage is 211 kg/ha of compound fertilizer, applied one week after transplanting. The study concludes that compound fertilizer is both agronomically effective and economically profitable for cabbage cultivation under the tested conditions.

Abstract

Sweet corn is a horticultural commodity that is widely cultivated and consumed in Indonesia. This study aimed to determine the growth and yield response of sweet corn plants to the application of various doses of ammonium sulfate fertilizer. The research was conducted at Pasir Kuda Experimental Field, Bogor, West Java. This experiment used a randomized complete block design (RCBD)with a single factor, namely the dose of fertilizer application. Treatments were arranged in 4 levels of application, namely: (1) control, (2) standard NPK fertilization, (3) 0.5 dose of N, (4) 1,0 doses of N, (5) 1,5 doses of N, and (6) 2,0 doses of N. The results of this test indicate that the application level of ammonium sulfate fertilizers at the application level of 1,0 doses N fertilizer treatment can generally provide plant height, stem diameter, number of leaves, stover weight, cob weight with husk, cob weight without husk, production plot-1, and productivity which are statistically higher than the control treatment. The application of 1,0 doses N fertilizer treatment had Relative Agronomic Effectiveness (RAE) values that meet the requirements to pass the fertilizer effectiveness test, with the highest RAE value obtained in the application of 1,0 doses N fertilizer at 188%.
