Abstract

One of the main pests and many damaging rice plants is gold snails. The damage caused can reach 13.2–96.5%. This pest is difficult to control despite the application of pesticides. The purpose of the study was to determine the effect of organic pesticide-producing plants on the mortality of gold snail pests in rice fields. The experiment using Complete Randomized Design consisted of 5 treatments, namely: P0 (control), P1 (tubal root extract), P2 (soursop leaf extract), P3 (lemongrass extract), P4 (papaya leaf extract) and P5 (jatropha leaf extract). The results showed that the highest average consumption rate was found at P1 (70.73%) and the lowest at P0 (1.73%). The highest average mortality rate from this pest was found at P1 (80) and lowest at P0 (0) during the observation period 4 hours after application. While at 8-hour observations the average mortality was highest at P4 and P5 (60) and lowest at P0 (13) after application. The highest average death time velocity was observed at P1 (3) and lowest at P0 (0) in the observation period 4 hours after application, while the highest average death time speed 8 hours after application was found at P4 and P5 (5) and lowest at P0 (2).

Abstract

Biological control of several types of pests and diseases of horticultural vegetables and plantations qualitatively and quantitatively. The results of the study found the genus Steinernema spp in every type of plant in both sample villages. The highest NEP population density was found in Negeri Rumahtiga in eggplant plants with an average population of infective juvenile phase NEP (661.8 heads) and the lowest average population is found in chili plants (228.8 heads). The highest average population in Wayame village was found in tomato plants (425.8 ji NEP), while the lowest average was in chili plants (245.0 ji). In addition, the results of various analyses of population density showed a real influence on entomopathogenic nematodes in Rumahtiga Country, while in Wayame village there was no real effect

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.
