Penelitian Ini Bertujuan Untuk Mengetahui Pengaruh Pupuk Organik Cair Ekstrak Babandotan (Ageratum Conyzoides) Dan Pupuk Kandang Ayam Terhadap Pertumbuhan Vegetatif Tanaman Jagung (Zea Mays). Penelitian Ini Telah Dilaksanakan Pada Bulan Desember 2018 – Juni 2018 Di Mini Screen Fakultas Pertanian Universitas Borneo Tarakan. Metode Yang Digunakan Adalah Rancangan Acak Kelompok (RAK),Terdiri Dari Enam Perlakuan Dan Empat Ulangan. Adapun Dosis Yang Digunakan Yaitu P0 (Kontrol), P1 (15 Ml Poc Babandotan), P2 (30 Ml Poc Babandotan) ,P3 (Pupuk Kandang Ayam), Dan P4 (15 Ml Poc Babandotan+Pupuk Kandang Ayam) , P5 (30 Ml Poc Babandotan + Pupuk Kandang Ayam 4 G), Hasil Penelitian Menunjukkan Bahwa Pemberian Dosis Yang Berbeda Berpengaruh Nyata Terhadap Jumlah Daun, Berat Basah Pupus Dan Berat Kering Pupus Tanaman Jagung Dan Berpengaruh Tidak Nyata Terhadap Tinggi Tanaman, Berat Basah Akar, Berat Kering Akar, Jumlah Akar, Panjang Akar, Rambut Akar, Volume Akar, Dan Nisbah Pupus Akar Tanaman Jagung. Dosis Terbaik Ditunjukkan Pada Perlakuan P5 (30 Ml Poc Babandotan + Pupuk Kandang Ayam 4 G).
Kesimpulan Dari Penelitian Ini Adalah Berdasarkan Hasil Penelitian Pengaruh Pupuk Organik Cair Ekstrak Babandotan (Ageratum Conzoides) Dan Pupuk Kandang Ayam Terhadap Pertumbuhan Akar Tanaman Jagung Bahwa Pada Perlakuan P5 (30 Ml Ekstrak Babandotan Dan Pupuk Kandang Ayam 4 G) Memberikan Pengaruh Terbaik Terhadap Peningkatan Jumlah Daun, Berat Basah Pupus Dan Berat Kering Pupus Dibandingkan Dengan Perlakuan Yang Lain.

This Study Aims To Determine The Effect Of Liquid Organic Fertilizer Babandotan Extract (Ageratum Conyzoides) And Chicken Manure On The Vegetative Growth Of Corn (Zea Mays). This Research Has Been Carried Out In December 2018 - June 2018 At The Mini Screen Of The Faculty Of Agriculture, University Of Borneo Tarakan. The Method Used Was Randomized Block Design (RBD), Consisting Of Six Treatments And Four Replications. The Doses Used Were P0 (Control), P1 (15 Ml Poc Babandotan), P2 (30 Ml Poc Babandotan), P3 (Chicken Manure), And P4 (15 Ml Poc Babandotan + Chicken Manure), P5 (30 Ml Poc Babandotan + Chicken Manure 4 G), The Results Showed That Different Doses Gave Significant Effect On The Number Of Leaves, Wet Weight Loss And Dry Weight Of Corn Plants And No Significant Effect On Plant Height, Root Wet Weight, Root Dry Weight, Amount Root, Root Length, Root Hair, Root Volume, And Ratio Of Root Loss Of Corn Plants. The Best Dose Was Shown In P5 Treatment (30 Ml Poc Babandotan + 4 G Chicken Manure). The Conclusion Of This Study Is Based On The Results Of The Study Of The Effect Of Liquid Organic Fertilizer Babandotan Extract (Ageratum Conzoides) And Chicken Manure On Root Growth Of Corn Plants That In P5 Treatment (30 Ml Of Babandotan Extract And Chicken Manure 4 G) Give The Best Effect On Increasing The Number Of Leaves , Wet Weight Was Lost And Dry Weight Was Lost Compared To Other Treatments.
