Abstract
Red Spinach has a high economic value compared to some other types of
spinach. High demand from some supermarkets, hotels, and restaurants. In some
developing countries, spinach promoted as a vegetable that could double that as
provider of nutrition and a source of public revenue. Superiority nutritional value
of red spinach is known as a highly nutritious vegetable because it contains
protein, vitamin A, vitamin C, and anthocyanins. To increase the growth, yield
and quality of red spinach, researchers used paranet and fertilizer N. The purpose
of this research (1) to known the level of shade is best for growth, yield and
quality of red, (2) to known the best fertilizer N on growth, yield and quality of
red spinach, and to known the interaction of shade and fertilizer N on growth,
yield and quality of spinach red. This research implemented in the garden
Experiment Wedomartani, Faculty of Agriculture UPN "VETERAN" Yogyakarta,
on August until October 2014. The research conducted with field trials were
arranged in a split plot factorial design 4x3. Main plot is paranet shade level is N0
(without paranet shade), N1 (25%), N2 (50%), N3 (75%). Sub Plot is fertilizier N
level is D1 (45 kg/ha), D2 (90 kg/ha), D3 (135 kg/ha). The results showed an
interaction shade treatment and dose of nitrogen to the anthocyanin content, fresh
weight per plot. The combination of 50% shade treatment with nitrogen dose of
135 kg / ha gives the best results in anthocyanin content and fresh weight per plot.
Shade paranet 50% (N2) are best, especially in affecting plant height (14, 21, 28,
35 days after planting), the number of leaves (14 days after planting), the levels of
anthocyanins, root volume, dry weight of plants, plant fresh weight. The dose of
nitrogen fertilizer 135 kg / ha affect the number of leaves (21 days after planting),
root volume, the levels of anthocyanins, and total fresh weight per plot.

Bayam merah (Alternanthera amoena Voss) mempunyai nilai ekonomis
tinggi dibandingkan dengan beberapa jenis bayam lainnya. Permintaan yang
cukup tinggi dari beberapa supermarket, hotel dan restoran. Di beberapa Negara
berkembang, bayam di promosikan sebagai sayuran yang dapat berfungsi ganda
yaitu sebagai pemenuh kebutuhan gizi dan sumber pendapatan masyarakat.
Keunggulan nilai nutrisi bayam merah dikenal sebagai sayuran bergizi tinggi
karena banyak mengandung protein, vitamin A, vitamin C, dan antosianin. Untuk
meningkatkan pertumbuhan, hasil dan kualitas bayam merah peneliti
menggunakan paranet dan pupuk N. Penelitian ini bertujuan untuk (1) mengetahui
tingkat naungan yang paling baik bagi pertumbuhan, hasil dan kualitas bayam
merah, (2) mengetahui dosis pupuk N yang paling baik terhadap pertumbuhan
hasil dan kualitas bayam merah dan (3) mengetahui interaksi naungan dan dosis
pupuk N terhadap pertumbuhan hasil dan kualitas bayam merah. Penelitian
dilaksanakan di kebun Percobaan Wedomartani Fakultas Pertanian UPN
“VETERAN” Yogyakarta, Kabupaten Sleman, Yogyakarta pada bulan Agustus
sampai Oktober 2014. Penelitian dilakukan dengan percobaan lapangan yang
disusun dalam Rancangan Petak Terbagi (Split Plot Design) secara faktorial 4 x 3.
Main Plot (Petak Utama) adalah tingkat naungan paranet yaitu N0 (tanpa
naungan), N1 (25%), N2 (50%), N3 (75%). Sub Plot (anak petak) adalah dosis
pupuk Nitrogen yaitu D1 (45 kg/ha), D2 (90 kg/ha), D3 (135 kg/ha). Hasil
penelitian menunjukkan terdapat interaksi perlakuan naungan dan dosis nitrogen
terhadap kadar antosianin, bobot segar perpetak. Kombinasi perlakuan naungan
50% dengan dosis nitrogen 135 kg/ha memberikan hasil terbaik pada kadar
antosianin dan bobot segar perpetak. Naungan paranet 50% (N2) paling baik
terutama dalam mempengaruhi tinggi tanaman (14, 21, 28, 35 hst), jumlah daun
14 hst kadar antosianin, volume akar, bobot kering tanaman, bobot segar tanaman.
Dosis pupuk nitrogen 135 kg/ha mempengaruhi jumlah daun (21 hst), volume
akar, kadar antosianin dan jumlah bobot segar perpetak.
Kata kunci : bayam merah, naungan paranet, Nitrogen
