Abstract

Cabbage production in 2022 in various regions in Indonesia will experience a decline, the largest decline in West Sumatra, reaching 11,005 tons. This condition is caused by a reduction in productive agricultural land and increasingly intensive attacks by plant pests. Cabbage leafworm (Plutella xylostella) and cropworm (Crocidolomia binotalis) are the main pests on cabbage plants which continue to be the main factor in reducing cabbage production. Plutella xylostella and Crocidolomia binotalis attacks, if not treated, can reduce cabbage production by up to 100%. Meanwhile, currently handling the main pests of cabbage plants still uses very excessive insecticides, both in dosage and spraying time intervals, this has a negative impact on the environment and human health. Integrated Pest Management (IPM) needs to be carried out, one of which is with entomopathogenic fungi. Metarizhium rileyi is a type of entomopathogenic fungus that efficiently and effectively controls several types of plant pests. This research aims to test the effectiveness of the entomopathogenic fungus Metarhizium rileyi against the main pests on cabbage plants in the UMM Rusunawa experimental field. This research used a simple Randomized Block Design (RBD) consisting of 2 control treatments and 3 treatments giving biological agents with various densities. The densities used in the treatment were 104 conidium/ml, 106 conidium/ml and 108 conidium/ml. Each treatment was infested with 4 cropworm larvae and 4 cabbage leafworm larvae. The results of a conidia density level of 108/ml in the Metarizhium rileyi fungus produced the highest percentage of mortality for Plutella xylostella larvae at 100% and Crocidolomia binotalis larvae at 90% and obtained the fastest time to kill 50% of test larvae (LT50) range of 2,193 days LT50 Plutella xylostella and 3,644 days LT50 Crocidolomia binotalis.

Abstract

Potato productivity in Indonesia remains relatively low at 13.38 t ha⁻¹, compared with its optimal potential yield of up to 26.5 t ha⁻¹. This low productivity is largely attributed to the use of poor-quality seed tubers, inefficient cultivation practices, and limited farmer access to appropriate technologies and production inputs. The present study aimed to evaluate the growth and yield performance of Generation-2 (G2) seed potatoes derived from stem cuttings and seed tubers of the Granola Lembang variety under field conditions in Pujon, Malang. The experiment was conducted using standard cultivation techniques, including the application of organic and inorganic fertilisers, hilling, irrigation, and integrated pest and disease management. Agronomic parameters observed included plant height, stem diameter, number of primary branches, number of leaves, number of tubers, and tuber weight per plant. Data were analysed using t-tests to compare the treatments. The results revealed significant effects of the treatments on all growth and yield parameters measured. T-test analysis showed p-values < 0.05 across all parameters at 56, 70, and 84 days after planting. These findings indicate that both stem cuttings and sprouted seed tubers can be effectively utilised for the production of G2 potato seed, thereby offering alternative approaches to improve seed availability and productivity in potato cultivation.
