FAKTOR BUDIDAYA DAN KAITANNYA DENGAN KEPARAHAN PENYAKIT KARAT PURU PADA SENGON (Falcataria moluccana (Miq.) Barneby & J.W. Grimes)

Abstract

Until now, gall rust disease is a major threat for Falcataria moluccana plantations in Indonesia. One of the environmental factors that can influence the development of plant diseases is the cultivation practice. However, the studies related to the influence of cultivation practice to the F. moluccana gall rust disease are still limited. This study aimed to determine the correlation between cultivation practice to the incidence and severity of F. moluccana gall rust disease. The incidence and severity of F. moluccana gall rust disease were observed from 47 planting sites distributed throughout Java. Its correlation to the cultivation practice was analyzed using chi square analysis followed by coordinate analysis. The results indicated that 6 of 13 variables were significantly correlated with disease incidence. Meanwhile, only 3 of 13 variables were significantly correlated to disease severity. These factors were plant age, use of organic fertilizer, and chemical control. Based on coordinate analysis result, organic fertilizer and chemical control application showed strong association with low level disease severity.

Agroforestry management systems through landscape-life scape integration: A case study in Gowa, Indonesia

“…Silk tree (F. moluccana), is native to Indonesia, namely Maluku, Papua, and South Sulawesi (Gunawan et al 2019), Papua New Guinea, and the Solomon Islands (Niemiec et al 2017). Silk tree (F. moluccana), is recognized for its rapid wood development (Lelana et al 2018;Gunawan et al 2019), with a canopy width and height of up to 10 m and 30 m, respectively, and an 80 cm trunk diameter (Hughes et al 2012). This plant, however, was shown to be an invasive species (Niemiec et al 2017;Nopiyanti et al 2019).…”

The Cause of Sengon (Paraserianthes falcataria) Damping-off Disease: Survey and Identification in Permanent Nursery, IPB University

“…Nilai skoring dilakukan berdasarkan Tabel 1. Nilai skoring dibuat berdasarkan Lelana et al (2018) Lelana et al (2018) Semai sengon dengan kondisi terserang penyakit dengan gejala damping-off kemudian diisolasi. Daun sengon dipotong ± 5 mm diantara bagian yang terserang dan sehat.…”

“…Penggunaan fungisida yang intensif saat semai dikeluarkan dari greenhouse ke open area menyebabkan intensitas keparahan penyakit berkurang drastis. Lelana et al (2018) menyatakan bahwa penggunaan pupuk organik dan pengendalian secara kimiawi memiliki asosiasi dengan intensitas keparahan penyakit yang rendah. Hal ini didukung oleh Cahyaningrum et al (2017) yang menyatakan bahwa besarnya intensitas serangan penyakit ditentukan salah satunya oleh kemampuan patogen dalam menyerang tanaman.…”

Capacity Building of Forest Local Community, Tree Seeds Providers and Forestry Extension Workers on Plus Tree Selection Technique in Kediri, East Java, Indonesia

“…Sengon, mahogany, acacia, teak, and African wood are among the plant species that are frequently chosen to be grown in the community forest [3]. Among those species Sengon (Falcataria moluccana) is preferred by community due to its ability to grow on all types of soil, short harvest life, and economic significance [4]- [6]. National Forest Estate (Perum Perhutani) cultivates sengon especially in Kediri Regency, East Java and engages local community in their plantation activities.…”
