RESPON PERTUMBUHAN BIBIT KARET (Hevea brasilliensis Muell. Arg) ASAL STUM MATA TIDUR TERHADAP PEMBERIAN MIKORIZA
No full textThis research method using a Random Design Group (RAK) nonfaktorial with 5 replicates, with four plant samples. The treatment is dosage of mycorrhizal (M) as follows: M0 = 0.0 g / plant, M1 = 2.5 g / plant, M2 = 5.0 g / plant, M3 = 7.5 g / plant, M4 = 10, 0 g / plant. Observed variable is the time to grow shoots (HST), height of shoots (cm), coiled shoots (cm), number of petiole (stalk), root length (cm), number of roots (pieces), root weight (g). The analysis showed that the diversity of mycorrhizal treatment dose is very real effect on all variables were observed. The results showed that giving doses of mycorrhizae 7.5 g / plant the best effect on rubber seedlings, as in the growing bud (HST), shoot height (cm), coiled shoots (cm), number of petiole (strands), weight of roots (g), root length (cm) and number of roots (pieces)

Penelitian dilaksanakan pada bulan Mei – Agustus 2017 di Screen House Fakultas Pertanian Universitas Palembang dengan ketinggian sekitar 6 m dpl. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola tunggal satu faktor. Faktor perlakuan pupuk organik hayati adalah Takaran Pupuk Organik Hayati yang terdiri dari P0 = Kontrol (tanpa perlakuan), P1 = Pupuk Organik Hayati 100 kg/ha, P2 = Pupuk Organik Hayati 200 kg/ha, P3 = Pupuk Organik Hayati 300 kg/ha, P4 = Pupuk Organik Hayati 400 kg/ha, P5 = Pupuk Organik Hayati 500 kg/ha. Data hasil penelitian dianalisis berdasarkan analisis sidik ragam (ANOVA) dan dilanjutkan dengan uji beda nyata jujur (BNJ) pada taraf 0.05 %. Hasil penelitian menunjukan bahwa pemberian takaran pupuk organik hayati sebanyak 400 kg/ha mampu meningkatkan hasil pertumbuhan tanaman seledri yang terbaik
UJI ADAPTASI PERTUMBUHAN VEGETATIF BEBERAPA GENOTIPE TANAMAN JAGUNG (Zea mays. L) PADA BERBAGAI KONDISI TERNAUNGI
No full textThe aims of this research was to evaluate aduptation ability of some maize varieties planted in tidal wetland in the condition of low light intensity against vegetative growth. The research was conducted at the Suka Tani Vallage, Tanjung Lago Subdistrict, Banyuasin District, South Sumatera Province, Indonesia. Split plot Design was used in this experiment by 22 varieties were tested as subplot and four levels of light intensity as main plots, each of treatment repeated three times. Result showed that light intensity significantly imfluence number of seed growing, number of leaves and heihgt of plant 45 days after planted. The most seed growing and number of leaves occured on C3 treatment (light intensity 360-400 µmol m-2s-1) and local variety Air Sugihan and B-41 variety. While light intensity 760-800 µmol m-2s-1 ,and variety B-26 give the highest of plant height
PENGARUH KONSENTRASI PUPUK PELENGKAP CAIR TERHADAP PERTUMBUHAN DAN PRODUKSI TOMAT RANTI (Lycorpercium pimpinelifolium)
No full textoai:jurnal.unpal.ac.id:article/4Penelitian ini dilakukan pada Bulan Februari 2013 sampai dengan Bulan Mei 2013 di Kelurahan Mariana Kecamatan Banyuasin I Kabupaten Banyuasin. Penelitian ini menggunakan Penelitian ini dilakukan dengan menggunakan Rancangan Acak Kelompok dengan 6 perlakuan dan ulangan sebanyak 4 kali serta 4 contoh tanaman. Analisis data hasil pengamatan dianalisis menggunakan analisis ragam (ansira). Adapun parameter yang diamati pada penelitian ini yaitu 1) Tinggi Tanaman (cm), 2) Jumlah Cabang (cabang), 3) Jumlah Buah Per Tanaman (buah), 4) Berat Buah Per Tanaman (g), 5) Berat Berangkasan Basah (g), dan 6) Berat Berangkasan Kering (g). Perlakuan konsentrasi pupuk pelengkap cair 3 ml per liter air merupakan perlakuan terbaik dalam mempengaruhi pertumbuhan dan produksi tanaman tomat ranti dimana dapat dilihat adanya peningkatan tinggi tanaman (66,92 cm), jumlah cabang (11,58 cabang), jumlah buah per tanaman (91,26 buah), berat buah per tanaman (832,08 g), berat berangkasan basah (430,17 g), berat berangkasan kering (96,67 g). Pupuk pelengkap cair didalam melakukan penanaman tanaman tomat ranti sehingga unsur hara yang diperlukan oleh tanaman baik unsur hara makro dan mikro dapat terpenuhi didalam peningkatan produksi dan produktivitas tanaman
KEANEKARAGAMAN ARTHROPODA DI EKOSISTEM TANAMAN PADI RATUN YANG DIAPLIKASIKAN BIOINSEKTISIDA Beauveria bassiana
No full textPenelitian ini bertujuan untuk mengetahui keanekaragaman arthropoda di ekosistem tanaman padi ratun yang diaplikasikan bioinsektisida Beauveria bassiana. Penelitian dilaksanakan pada bulan Agustus - Oktober 2013. Metode yang digunakan dalam penelitian ini adalah metode eksperimental dengan menggunakan dua perlakuan dan empat ulangan. Pengambilan artropoda di tajuk dilakukan dengan menggunakan jaring serangga yang dilakukan 15 kali ayunan ganda. Hasil penelitian menunjukan bahwa populasi hama dari umur 1-8 minggu setelah potong menunjukan hasil yang berfluktuasi. Hasil analisis dengan menggunakan uji chi-square populasi hama antara petak yang diaplikasikan bioinsektisida dengan petak kontrol tidak berbeda nyata. Persentase serangan hama di tanaman padi ratun akibat serangga hama meningkat dengan bertambahnya umur tanaman. Persentase serangan tanaman padi ratun tertinggi pada umur 7-8 msp. Indeks keanekaragaman ditajuk tertinggi pada petak kontrol, namun di permukaan tanah tertinggi terjadi di petak yang diaplikasikan bioinsektisida
APLIKASI BIO URINE DAN PUPUK NITROGEN PADA TANAMAN JAGUNG MANIS (Zea mays sacharata) DI LAHAN RAWA
No full textThis research has been conducted in the Faculty of Agriculture experiment station Musi Rawas This study aims to look at the effect of giving cows Bio Urine and various doses of nitrogen fertilizer on the growth and yield of sweet corn in swamp land. This study uses a randomized block design consisting of 2 factors were repeated 3 times. Each treatment unit in a grid with a size of 2 m x 1 m. The treatment in this study are as follows: the first factor treatment biourine B1 = 25 ml / liter of water, B2 = 75 ml / liter of water and B3 = 100 ml / liter of water and treatment factors both doses of nitrogen fertilizer N1 = 100 kg / ha, N2 = 150 kg / ha, and N3 = 250 kg / ha. The results showed the treatment biourine 75 ml / liter of water (B2) showed the best results on plant height. While treatment biourine as much as 100 ml / liter of water (B3) showed the best results at the variable length of the cob, cob diameter, heavy crop cob, cob heavy perplot, heavy wet upper canopy, and wet weight roots. For the dosage of nitrogen fertilizer dose of 150 kg / ha (N2) showed the best results on plant height, weight wet canopy top, ear length, ear cropping weight and cob weight per plot. While the dose of 200 kg / ha (N3) give the best results at the variable wet weight root and ear diameter
PENGARUH TAKARAN PUPUK ORGANIK CAIR TERHADAP PERTUMBUHAN TANAMAN SAWI CAISIM (Brassica Juncea L) DI POLIBAG
No full textThis study aimed to determine the effect of liquid organic fertilizer on improving growth and yield of mustard greens (Brassica juncea, L.), planted in randomized block design (RBD) with one treatment factor. Factors tested were dose Liquid Organic Fertilizer (LOC) which consists of cow dung A0 = control (no treatment), A1 = Liquid Organic Fertilizer Cattle manure 10 cc/liter of water, A2 = Liquid Organic Fertilizer Cattle manure 15 cc/liter of water, and A3 = Liquid Organic Fertilizer 20 cc/liter of water. The treatment level test was repeated 3 times to have 12 sets of experiment. Each set consisted of 12 mustard green plants . The data were further analyzed using variance procedure and continued using the Honest Significant Difference (HSD) test at the level of 0.05%. The results showed that, the application of Liquid Organic Fertilizer doses gave different responses in the growth and production of mustard greens. Organic Liquid Fertilizer of 15 cc/liter of water produces increased plant height, number and width of leaves and the wet weight of plants
