Abstract

The control of the Spodoptera exigua Hubner (Lepidoptera: noctuidae) through sex pheromones is feasible by mass trapping, mating disruption, and population monitoring. Both synthetic sex pheromones and virgin females were used on the mass trapping and population monitoring methods as attractant source. The virgin females must be available through the mass rearing without affected on its pheromone content production. Therefore, a study on the response of the female’s pheromone which reared by artificial and natural diets was important to be done. The GCMS analysis result had shown that female’s pheromone glands extract which had reareded by natural diets contained tetradecan-1-ol (0.23%) pheromone compounds and several other compounds, such as hexadecane (14.31%), heptadecane (0.42%), nonadecane (1.09%), and beta-caryophyllene (1.37%). Meanwhile, only tridecanol (3.39%), hexadecane (8.52%), nonadecane (0,23%), and trans-caryophyllene (3.11%) compounds had been found on the artificial ones. The cross-copulation test showed that both types of moths could do mating. The field trapping test showed that both extracts were attractive to males

Abstract

Tujuan dari penelitian ini adalah mengetahui pengaruh pengolahan tanah dalam menekan pertumbuhan gulma sertameningkatkan produksi tanaman kedelai. Penelitian dilaksanakan di kebun percobaan Fakultas Pertanian, Universitas Mulawarman diDesa Karang Tunggal, Kecamatan Tenggarong Seberang. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan empatperlakuan (p0 tanpa olah tanah, p1 olah tanah satu kali, p2 olah tanah dua kali, p3 olah tanah tiga kali) dan enam ulangan. Analisis datamenggunakan sidik ragam. Karakter agronomi kedelai yang diamati meliputi tinggi tanaman, waktu berbunga, jumlah polong hampa,berat biji saat panen, berat biji kering, dan produksi per hektar. Perlakukan pengolahan tanah tidak berpengaruh terhadap pertumbuhangulma dilihat dari Nilai Jumlah Dominan total berat kering gulma, keragaman gulma, dan karakter agronomi.

Abstract

Ultisols in Indonesia have the potential for agricultural development, but the soils have low pH and nutrient contents that hinder plant growth and yield. Using animal manure can be an alternative to improve soil productivity and crop yields. This study aimed to examine the effects of animal manure on the chemical properties of Ultisol, yield, and secondary metabolic of Zingiber montanum. The treatments tested were combinations of types of manure (cow and chicken manure) and manure application levels, namely P0 (control), P1 (cow manure 20 t/ha), P2 (cow manure 40 t/ha), P3 (cow manure 60 t/ha), P4 (chicken manure 20 t/ha), P5 (chicken manure 40 t/ha), and P6 (chicken manure 60 t/ha). The results showed that the application of chicken manure of 60 t/ha increased N and P contents of the soil, and the application of cow manure of 60 t/ha increased soil cation exchange capacity. The application of cow manure of 60 t/ha gave the highest plant height, the number of leaves, and the number of at 18 weeks after planting, while the application of chicken manure dose of 60 t/ha produced the longest plant roots. The highest fresh and dry rhizome weight was observed for the 60 t/ha cow manure treatment. The highest secondary metabolic levels in each parameter were found in dry rhizomes (phenolic, flavonoid, and tannin) and fresh rhizomes (phenolic and flavonoid), with the highest tannin compound in the treatment of 40 t chicken manure/ha. The application of chicken manure at a dose of 60 t/ha resulted in a strong antioxidant yield in fresh and dry rhizomes.
