RESPON TIGA VARIETAS BAWANG MERAH TERHADAP DUA MACAM PUPUK KANDANG DAN EMPAT DOSIS PUPUK ANORGANIK

Abstract

Percobaan pot tentang respon tiga varietas bawang merah terhadap dua macam pupuk kandang dan
empat dosis pupuk anorganik telah dilakukan di Screen house (rumah kasa) pada Kebun Percobaan Batang,
Batang. Rancangan Percobaan yang digunakan adalah Rancangan Acak Kelompok Lengkap (RAKL). Hasil
penelitian menunjukkan bahwa varietas Bima Juna (V1) menunjukkan tinggi tanaman, dan volume umbi
tertinggi. Varietas Tiron (V3) menunjukkan jumlah anakan per rumpun, jumlah daun per rumpun, dan
jumlah umbi per rumpun tertinggi. Macam pupuk kandang berpengaruh pada bobot basah umbi per rumpun,
bobot kering umbi per rumpun dan volume umbi. Pupuk kandang yang berasal dari kotoran ayam (M2)
memberikan hasil yang lebih tinggi dibandingkan yang berasal dari kotoran sapi (M1). Dosis pupuk
anorganik berpengaruh pada bobot kering umbi per rumpun. Bobot kering umbi per rumpun tertinggi
dicapai pada dosis pupuk anorganik 200 kg/ha (P3) dan pupuk kandang 20 t/ha. Tidak terdapat interaksi
antara varietas, macam pupuk kandang dan dosis pupuk anorganik pada semua variabel yang diamati.
Varietas Bima Juna (V1), pupuk kandang yang berasal dari kotoran ayam (M2) dan dosis pupuk anorganik
400 kg/ha (P1) mempunyai nilai serapan N dan P jaringan tanaman bawang merah tertinggi.

Kata kunci: bawang merah, pupuk kandang, pupuk anorganik, varietas

 

ABSTRACT
The experiment about the response of three varieties of shallot to two kinds of manure and four dosage
inorganic fertilizers was conducted in screen house at Batang Experimental Station, Batang. Randomized
Complete Block Design was employed to arrange environmental site. The result showed that Bima Juna
variety (V1) has the highest plant height and volume of bulb. Tiron variety (V3) has the highest amount of
tiller per plant, amount of leaves per plant and the amount of bulb per plant. The kind of the manure
significantly affected fresh weight of bulb per plant, dry weight of bulb per plant and volume of bulb. The
plants fertilized with chicken manure (M2) produced higher yield than that of cow manure (M1). Dosage of
inorganic fertilizer significantly affected the dry weight of bulb per plant. The highest was obtained in dry
weight of bulb per plant 200 kg/ha inorganic fertilizer (P3) and 20 t/ha manure combination. There was no
interaction between varieties, the kind of manure and inorganic fertilizer dosage for all of the variables. Bima
Juna (V1) variety, plant fertilized with chicken manure (M2) and plant fertilized with inorganic fertilized
dosage 400 kg/ha (P1) has the highest absorption N and P.
