Abstract

The potential for agribusiness growth of sweet corn (Zea mays Sacharata Sturt) is quite high because it is very popular and favored by consumers. The study aimed to determine the effect of the dose of vermicompost fertilizer on the growth and yield of sweet corn. The research was conducted using a randomized block design (RBD) with 3 replications, namely K0 = control, K1 = 50 g/plant, K2 = 100 g/plant, and K3 = 150 g/plant. There were 12 experimental units; each treatment was 6 plants, so the total number of plants was 72. The application of vermicompost can increase the growth and production of sweet corn plants. Based on the study's results, sweet corn's growth and yield were significantly affected by the treatment of vermicompost with a dose of 150 g. It was found that the main pest species that infected this plant were Helicoverpa armigera Hubner, Ostrinia furnacalis, and Oxya sp. It is expected that the results of the study can be used in the future regarding the application of a combination of compost and other biological fertilizers in the field.

Abstract

This study aims to inventory land resources and management practices of groundnut smallholder farms in the Ohoinol agricultural area. assess land suitability for groundnut in ZAE II.5. to create a land suitability map for groundnut based on predictions of relative production potential. The method used was survey method, analytical approach, free survey observation distance by conducting identification (boring) and making complete soil profiles and current land use in the sample area determined in 20 land units. The observation results found three types of soil, namely Rensina (Calsiudols), Litosol (Udorthents), and Cambisol (Eustrudepts), which were carried out on community gardens. Groundnut planting activities take place in the eastern season (summer) twice and the western season (rainy season) once. The length of the growth period (LGP) is about 240 days, compared to the peanut growth cycle of 90-140 days. the LGP has no impact on the peanut growth age of 90-140 (average 115 days) and a decrease in production; in other words, the LGP is optimal, namely 80-100% of the subsistence level production achievement of 1,305 Kg dry beans/ha (VS Class = S1). Assessment of groundnut suitability (rooting depth ± 30 cm) based on soil conditions in land units RL015 and RL215 (42 ha in total) is mostly very suitable and has no effect on reducing subsistence level production

Abstract

Spell analysis is one of the indicators that can be used to measure the level of vulnerability of a region to drought. This study aims to determine the chances of a series of dry days during the effective growing season during El Niño on Ambon Island. Data analysis was carried out with the following stages: (1) calculating rainfall probability at 75% using the ranking order method and potential evapotranspiration using the Penman-Monteith method in the Cropwat 8.0 Program package, (2) calculating land water balance and determining the effective growing season based on optimum soil water content, and (3) determining the years of El Niño occurrence and the chances of a series of dry days. The results of the study showed that the effective growing season on Ambon Island lasted for 7 months, from April to October. The El Niño event on Ambon Island during the period 1979–2023 tends to occur once every three years. The chances of a series of dry days ≥ 5 days during the growing season ranged from 56 to 88%; ≥ 10 days: 27 to 88%; ≥ 15 days: 7 to 80%; and ≥ 20 days: 0 to 47%.

Abstract

The purpose of this study was to determine how several varieties of soybean (Glycine max (L.) Merrill) responded to the provision of composted rice straw waste to enrich goat manure in terms of growth and production. This study used a factorial randomized group design, a method with two factors and three replications. In this study, the first factor was soybean variety (V) divided into four parts, such as V1=Grobogan Soybean Variety, V2=Anjasmoro Soybean Variety, V3=Devon Soybean Variety, and V4=Wilis Soybean Variety. The second factor is grouped from K0 = 0 kg/plot, K1 = 1 kg/plot, K2 = 2 kg/plot, and K3 = 3 kg/plot as four components of rice straw waste compost enriched with goat manure. Meanwhile, the parameters that became the object of research were plant height (cm), number of productive branches, stem diameter (mm), number of pods, number of filled pods, number of empty pods, and weight of 100 seeds. The results explained that the growth response of soybean varieties influenced plant height, number of pods, number of filled pods, number of empty pods, seed production, and 100-seed weight. In contrast, the number of productive branches and stem diameter had no effect. Giving rice straw compost enriched with goat manure affects the number of productive branches and the number of filled pods, while plant height, stem diameter, number of pods, number of empty pods, seed production, and 100 seed weight do not have an effect. The interaction between the application of several varieties of soybean plants and composted rice straw waste enriched with goat manure did not show a significant effect on all parameters of the growth and production of soybean plants.

Abstract

Maize (Zea mays) plays an important role in the diet of the community after rice and has the potential to be a substitute for rice. One of the causes of the decline in corn productivity is the presence of plant-disrupting organisms, namely corn stalk borer (Ostrinia furnacalis) and corn cob borer (Helicoverpa armigera). Waimital Village, Kairatu Subdistrict, West Seram Regency is one of the corn center villages where farmers rely on synthetic insecticides in pest control without knowing the intensity of the damage caused. This study aims to determine the number of populations and the intensity of damage caused by Ostrinia furnacalis and Helicoverpa armigera pests that attack corn plants, as well as the relationship between the number of populations and the intensity of damage to each pest. The method used was the survey method in the corn planting area of Waimital village, then 5 farmers were taken with the determination of plants divided into 4 plots with details of each plot of 10 plants. The results of this study showed that the average population of Ostrinia furnacalis was 4.37 heads, the average population of Helicoverpa armigera was 1 head, the average damage intensity of Ostrinia furnacalis was 42.71% (medium criteria), the average damage intensity of Helicoverpa armigera was 11.83% (light criteria) and the relationship between Ostrinia furnacalis and Helicoverpa armigera pest populations and damage intensity showed that the larger the pest population, the higher the damage intensity.

Abstract

This research aims to analyze the potential of essential compounds of Cinnamonum burmannii and Cinnamonum cullilawan as a bioagent for Fusarium oxysporum and to test the efficacy of both essential oils in controlling the growth of the fungus F. oxysporum. Oil extraction was carried out using the steam-water distillation method, and analysis of the components of the oil compounds of the cinnamon was carried out using the GC-MS method. Essential oils were tested for their efficacy for inhibiting F. oxysporum with four concentrations, namely 0.06%, 0.125%, 0.25%, and 0.5% on PDA and PDB media. The results show that the main essential compound in C. burmannii is cinnamaldehyde at 20.61%, and in C. cullilawan, it is eugenol at 26.33%. The essential compounds of both have antifungal activity against F. oxysporum, with a concentration rate of 0.125% being able to inhibit the growth of F. oxysporum. The main active compounds, such as cinnamaldehyde and eugenol, play an important role in the fungus control mechanism. This research concludes that the essential compounds from both have the potential to inhibit F. oxysporum growth.
