Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi berbagai dosis biochar
terhadap karakter fisiologi dan hasil bawang merah, mengetahui pengaruh pemberian
berbagai dosis mikoriza terhadap karakter fisiologi dan hasil bawang merah, dan mengetahui
pengaruh berbagai dosis biochar dan dosis mikoriza terhadap karakter fisiologi dan hasil
bawang merah. Penelitian dilaksanakan pada bulan April sampai September 2019, di rumah
plastik experimental farm Fakultas Pertanian,Universitas Jenderal soedirman. Penelitian
menggunakan Rancangan Acak Kelompok Lengkap (RAKL) faktorial dengan dua faktor dan
tiga ulangan. Faktor pertama yaitu dosis mikoriza yang meliputi 0 g/polibag, 1 g/polibag dan
2 g/polibag. Faktor kedua yaitu dosis biochar yang meliputi 0 t/ha, 2,5 t/ha, 5 t/ha dan 10 t/ha.
Variabel yang diamati meliputi tinggi tanaman, total panjang akar, bobot kering akar, laju
pertumbuhan tanaman, laju asimilasi bersih tanaman, klorofil daun, persentase infeksi akar,
serapan P jaringan tanaman, bobot umbi, bobot tanaman dan indeks panen. Hasil penelitian
menunjukkan bahwa pemberian biochar 2,5 t/ha, 5 t/ha dan 10 t/ha hanya mampu
meningkatkan tinggi tanaman dan persentase infeksi akar. Pemberian mikoriza 1 g/polibag
dan 2 g/polibag hanya mampu meningkatkan tinggi tanaman, persentase infeksi akar dan
serapan P jaringan tanaman. Pemberian biochar dan mikoriza hanya mampu meningkatkan
tinggi tanaman dan persentase infeksi akar.

This This study aims were to know effect of the application of various biochar dosage
on the physiological characters and shallot yield, effect of the application of various
mycorrhiza dosage on the physiological characters and onion yield, and both effects of
various dosages of biochar and mycorrhiza on physiological characteristics and shallot
yield. The study was conducted from April to September 2019, at experimental farm screen
house of the Faculty of Agriculture, Jenderal Soedirman University. The study used a
factorial Complete Randomized Block Design (RCBD) with two factors and three
replications. Factor of mycorrhiza dosage viz. 0 g/polybag, 1 g/polybag and 2 g/polybag and
biochar dosage viz. 0 t/ha, 2.5 t/ha, 5 t/ha and 10 t/ha were tested with three replication. The
observed variables were plant height, total root length, root dry weight, plant growth rate,
net assimilation rate of plants, leaf chlorophyll, percentage of root infection, plant tissue P
uptake, tuber weight, plant weight and harvest index. The results showed that the application of biochar 2.5 t/ha, 5 t/ha and 10 t/ha had been able to increase plant height and percentage of root infection. The application of mycorrhiza 1 g/polybag and 2 g/polybag had been able to increase plant height, percentage of root infection and plant tissue P uptake. The both applications of biochar and mycorrhiza had been able to increase plant height and percentage of root infection.
