Pengendalian weed seed bank penting dalam strategi pengendalian gulma secara terpadu. Sejumlah teknik untuk mengurangi seed bank tergantung system pertanian, lokasi, dan penguasaan gulma. Bahan aktif Indaziflam merupakan salah satu herbisida pre emerganceyang digunakan sebagai pengendalian gulma untuk mengantisipasi resistensi dan suksesi gulma terutama terhadap herbisida. Penelitian bertujuan untuk menentukan efikasi indaziflam terhadap kedalaman tanah dan daya tumbuh seed bank gulma E. indica. Percobaan menggunakan rancangan acak kelompok (RAK) faktorial dengan tiga ulangan. Faktor pertama yaitu herbisida dan tidak menggunakan herbisida, faktor kedua kedalaman tanah meliputi kedalaman 0 cm, 2 cm, 4 cm dan 8 cm. Dan faktor ketiga yaitu kadar air tanah meliputi 25% KL, 50% KL, 75% KL dan 100% KL.Hasil menunjukkan bahwa perlakuanherbisidaberpengaruhnyatapadaperlakuantanpaherbisidaterhadap parameter gulma yang tumbuh, dan kedalaman tanah 0 cm dan 2 cm berpengaruh nyata terhadap kedalaman tanah 4 cm dan 8 cm dan perlakuan kadar air 100% KL bepengaruh nyata pada kadar air 25% KL terhadap gulma yang tumbuh, tetapi tidak berpengaruh nyata pada kadar air 50% KL dan75% KL

ABSTRACT
Nico Jan Sianipar : Effect indaziflam and depth soil of grow seed bankEleusineindicaL.Gaertn.Supervised by Edison purba and mariati.
Controlling seed bank of weed is important in an integrated weed control strategy. A number of techniques to reduce the seed bank depending on the agricultural system, locations, and control weeds. The active ingredient herbicide Indaziflam is one of the pre emergance used as a weed control to anticipate resistance and a succession of weeds, especially to the herbicide. The objective of this study was to determine the efficacy indaziflam against soil depth and ability to grow weed seed bank E. indica. Experiments using a randomized block design factorial with three replications. first factor was aplication herbicide and not use herbicide, the second factor includes the depth of soil 0 cm, 2 cm, 4 cm and 8 cm. And the third factor was Soil Water Content includes 25%, 50%, 75% and 100%field capacity. The results showed that the real effect on the herbicide treatments without herbicide treatment on parameters weeds, and soil depth of 0 cm and 2 cm real impact on soil depth of 4 cm and 8 cm and the treatment of the soil water content of 100%field capacity real impact on the water content of 25%field capacity against weeds, but had no significant effect on the water content of 50%field capacity and 75%field capacity.
