The objective of this research was to study the response of tomato plant on paclobutrazol and different planting media composition. The study used Completely Randomized Design factorial 4x3with the first factor wasapplication of paclobutrazol 0 ppm (P0), 50 ppm (P1), 100 ppm (P2), dan 150 ppm (P3), and the second factor was composition of planting media (soil:compost) 80%:20% (M1), 60%:40% (M2), dan 40%:60% (M3),with 3 replications. The parameters observed were plant height, number of leaves, number of flowers, leaf chlorophyll content, number of fruit. Data were subjected to analysis of variance and further test by Duncan's Multiple Range Test (DMRT). The results showed that the application of paclobutrazol doses 50, 150 ppm, and without paclobutrazol (control) resulted in the number of flower of 70.56, leaf chlorophyll content index of 53.16, and plant height of 157.78 cm that ware significantly higher (p<0.05) than other treatments. The treatment without paclobutrazol with 60%:40% planting composition resulted in a significantly higher (p<0.05) leaf number than other treatments. Paclobutrazol doses of 100 ppm and 60%:40% of planting media composition yielded 10.33 fruitsthat was higher (p<0.05) than other treatments.

The purpose of this research was to analyze the response of growth and production of red rice (Oryza nivara) under drought and nanosilica fertilization condition. This research was conducted in Greenhouse and Laboratory of and Plant Physiology and Breeding of at Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarang from April to July 2017. The research was arranged using completely randomized factorial design. The first factor was drought stress (control, drought 20-35 DAP (Days After Planting), 40-55 DAP and 55-70 DAP). The second factor was the use of nanosilika fertilizers (without nanosilika, with nanosilica). The data were analyzed by anova and followed by Duncan’s Multiple Range Test (DMRT). The results showed that the drought stress during tiller production stage decreased the total number of tillers, productive tillers and grain weight per clump, but not in weight of one thousand seeds. Drought stress during flowering stage and seed filling only decreases the weight of one thousand seeds. Application of nanosilica increases the number of productive tillers and the weight of grain per hill. There was no interaction between drought stress treatment and nanosilika fertilization. Keywords: red rice, production, drought, nanosilica.

ABSTRACT The purpose of the research was to determine the effect of plant spacing and type of biofertilizer to the production of coriander biomass. This study used Randomized Block Design with two factors and repeated 3 times. The first factor was the different plant spacing (A) ie 20 × 20 cm (A0), 20 × 15 cm (A1) and 20 × 10 cm (A2). The second factor was the type of biofertilizer (B) ie without biofertilizer (B0), with biofertilizer A (B1) and with biofertilizer B (B2). The parameters observed were number of leaves, leaf area, leaf chlorophyll content, plant biomass per plant and production of plant biomass per plot. Data were analyzed using Duncan Multiple Range Test (DMRT) test of 5% level. The result of the analysis of different treatment range of spacing and the application of biofertilizer did not give interaction on the production of coriander biomass. Plant spacing of 20×20 cm (A0) increases leaf area and chlorophyll contents. Plant spacing of 20×10 cm (A2) yields the highest crop production per plot. The application of biofertilizer significantly increases the number of leaves and leaf area compared without biofertilizer. Keywords: Coriander, plant spacing and biofertilizer ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh jarak tanam dan jenis pupuk hayati berbeda terhadap produksi biomassa ketumbar. Penelitian ini menggunakan Rancangan Acak Kelompok dengan dua faktor dan diulang sebanyak 3 kali. Faktor pertama adalah jarak tanam yang berbeda (A) yaitu 20 × 20 cm (A0), 20 × 15 cm (A1) dan 20 × 10 cm (A2). Faktor kedua adalah jenis pupuk hayati (B) yaitu tanpa pupuk hayati (B0), dengan pupuk hayati A (B1) dan dengan pupuk hayati B (B2). Parameter yang diamati adalah jumlah daun, luas daun, kandungan klorofil daun, biomassa ketumbar per tanaman dan produksi biomassa ketumbar per petak. Data dianalisis dengan menggunakan uji Duncan Multiple Range Test (DMRT) taraf 5%. Hasil analisis ragam perlakuan jarak tanam dan jenis pupuk hayati berbeda tidak memberikan interaksi pada produksi biomassa ketumbar. Jarak tanam 20 × 10 cm (A0) meningkatkan luas daun dan kandungan klorofil. Jarak tanam 20 × 10 cm (A2) menghasilkan produksi tanaman per petak yang paling tinggi. Aplikasi pupuk hayati secara signifikan meningkatkan jumlah daun dan luas daun dibanding tanpa pupuk hayati. Kata kunci : Ketumbar, jarak tanam dan pupuk hayati.

ABSTRACTThis research aimed to indentify the impact of single species (G. fasciculatum, Acaulospora sp., G. etunicatum), double species, and multi-species AMF inoculation for plant growth and Pb accumulation ability of marigold plant. The research used monofactor randomized complete design with eight treatments and three replications.The treatments were M0. Control, M1. G. fasciculatum, M2. Acaulospora sp., M3. G. etunicatum, M4. G. fasciculatum + Acaulospora sp., M5. G. fasciculatum + G. etunicatum, M6. Acaulospora sp. + G. etunicatum, dan M7. G. fasciculatum + Acaulospora sp. + G. etunicatum. The parameters observed were plant height, number of branches, BCF, TF, and final concentration of Pb. Data analyzed using anova and followed by DMRT at α = 5%. The result indicated that AMF inoculation had significantly impact to the plant growth of marigold, BCF value, and Pb final concentration, but had no impact to the TF value. Inoculation of G. fasciculatum(M1) showed the highest plant growth of marigold. Inoculation of G. fasciculatum + Acaulospora sp. + G. Etunicatum(M7)showed the highest ability of Pb accumulation (BCF) and the lowest Pb final concentration in growing media. Based on BCF and TF values, the mechanism of Pb accumulation by marigold is phytoextraction.Keywords: Marigold, Pb, G. fasciculatum, Acaulospora sp., G. etunicatum. ABSTRAK Penelitian ini bertujuan untuk mengkaji pengaruh inokulasi CMA tunggal (G. fasciculatum, Acaulospora sp., G. etunicatum), ganda, dan multi-spesies terhadap pertumbuhan tanaman dan kemampuan akumulasi Pb pada marigold. Penelitian dilaksanakan menggunakan Rancangan Acak Lengkap (RAL) monofaktor dengan delapan perlakuan dan tiga ulangan. Perlakuan yang diberikan adalah M0. Kontrol, M1. G. fasciculatum, M2. Acaulospora sp., M3. G. etunicatum, M4. G. fasciculatum + Acaulospora sp., M5. G. fasciculatum + G. etunicatum, M6. Acaulospora sp. + G. etunicatum, dan M7. G. fasciculatum + Acaulospora sp. + G. etunicatum. Parameter penelitian meliputi tinggi tanaman, jumlah cabang, TF, BCF, dan konsentrasi Pb akhir media tanam. Data dianalisis ragam dan dilanjutkan uji jarak berganda Duncan pada taraf α = 5%. Hasil penelitian menunjukkan inokulasi berbagai spesies CMA berpengaruh terhadap pertumbuhan tanaman, nilai BCF, dan kadar Pb akhir media tanam, tetapi tidak berpengaruh terhadap nilai TF. Inokulasi G. fasciculatum(M1)memberikan pertumbuhan tanaman marigold tertinggi. InokulasiG. fasciculatum + Acaulospora sp, dan G. etunicatum(M7) menunjukkan kemampuan akumulasi Pb (BCF) tertinggi dan kadar Pb akhir media tanam terendah. Berdasarkan nilai BCF dan TF, mekanisme tanaman marigold dalam mengakumulasi logam Pb adalah fitoekstraksi.Kata kunci : Marigold, Pb, G. fasciculatum, Acaulospora sp., G. etunicatum.
