Other organic fertilisers frequently used by farmers were goat manure and granulates of organic fertilisers. • Fertilisers are applied at higher application rates and at higher costs in inter/multiple cropping systems than in mono cropping systems. • There are many different organic fertiliser products used by farmers at an average application rate of 13 and 18 tons/ha at an average cost of 5.2 and 7.0 million IDR/ha in mono and inter/multiple

Consumer demand for potato in Indonesia increases while production stagnates. Government policy recognized this discrepancy and prioritized efforts to increase potato yields through farmer support programs with moderate effects to date. This study aimed to decompose potato yield gaps and identify agronomic yield constraints in West Java. Actual yield and management practices of 178 farm registrations over five consecutive growing seasons were analyzed with stochastic frontier analysis. The potential yield (Yp) for each registration was simulated with the LINTUL-POTATO-DSS crop model. The overall yield gap was decomposed into its efficiency, resource, and technology components. The potato yield gap was 21.5 t ha -1, corresponding to 54% of Yp. The efficiency and technology yield gaps were both ca. 10 t ha -1, corresponding to 26% of Yp, and the resource yield gap was negligible. All fields received sufficient inputs for potential production but most inputs were used inefficiently. An early first fungicide spray after emergence and frequently spraying to control late blight increased yields significantly. The seed generation planted was critical to potato yield gaps as yield decreased significantly with older generations. Some high yielding fields, however, were also planted with older generations, so other production factors contributed to the yield gap as well. Improving potato yield will require well performed late blight control, the use of high-quality seed, and improved management practices, which include reduced input rates, to reduce current yield gaps sustainably.

“…Some studies have investigated factors that affect the behavior of the farmers to use pesticides such as the characteristics of farmers, training (Hashemi & Damalas, 2011;Khan, Mahmood, & Damalas, 2015), education, various perceptions such as risk and technology of pesticides (Wilson & Tisdell, 2001), attitudes (Liu & Huang, 2013;Wang, Tao, Yang, Chu, & Lam, 2017), as well as external driving forces such as government regulations (Marcoux & Urpelainen, 2011;Schreinemachers & Tipraqsa, 2012). The best commodity for the horticulture sub-sector in Indonesia, one of which is potatoes which are national superior commodities with high economic value (Pronk et al, 2018).…”

This study aims to analyze the perception of farmers in Central Java, toward the organic pesticides regarding their benefits, the safety of use, price and quality, easiness level, usage, the internal, and external factors affecting the perception of farmers, then level of education and knowledge of pesticide organic. This study is cross-sectional research with a sample of 36 potato farmers from Dieng Plateau, uses primary data obtained from the questionnaire. The results showed that the main perception of using organic pesticide was influenced by internal factors, the lowest perception score is for the usage. The components of this paper consist of introduction, literature review, materials and methods, result and discussions, conclusions with limitation and future research. Keywords : Farmer, potato, pesticide, perception
