Abstract

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.

Abstract

Setting the temperature of the storage space of seeds and storage containers will greatly affect the quality of the seed. The aim of this research was to study the effect of temperature treatment, storage container and their interaction on seed quality and seedling growth of chilli. The study was conducted in Jetis Village and Laboratory of Plant Physiology and Breeding, Faculty of Animal and Agricultural Sciences, Diponegoro University from January to June 2017. The study was conducted using nesting experiments on the basis of Completely Randomized Design (RAL). The first factor was Storage Temperature (R1 = Room Temperature 24-29 oC, R2 = Refrigerator Temperature 5oC) and second factor was storage container nested at storage temperature that was (P1 = Alumunium foil, P2 = Paper and P3 = Plastic). Each treatment had 5 replications and each replication consisted of 100 seeds, so there were 30 experimental units. The data were analyzed by using analysis of variance (ANOVA) and continued with test of HSD (Honesty Significant Difference) 5% significance level. The results showed that the storage temperature (5oC) temperature increased the temperature and the seed vigor index was larger than the room temperature (28oC), the aluminum foil packaging produced the maximum growth potential and germination rate was higher than the plastic and paper packaging but there was no different growth rate and index vigor. Low storage space temperatures (5oC) can not maintain maximum seed quality where the 4 parameters were still below the standard quality of the seed. Seeds stored in low temperature (5oC) rooms producedfresh weight and dry weight of seedlings larger than high temperature (28oC), but the number of leaves, seed height and hypothetical vigor index were not significantly different. The aluminum foil packaging producedfresh weight and dry weight of seeds higher than plastic and paper packaging. However, the number of leaves, the height of seed and the hypothetical vigor index were notsignificantly different. Keywords : Temperature, container store, seeds quality, seedling growth, chilli.

Abstract

ABSTRACT The purpose of the research was to obtain the morphological variability of M1 sunflower ornamental plant and information of lethal doses (LD50) effect of mutation by gamma ray irradiation. The research was arranged in monofactor experimental with Completely Randomized Design (RAL) with 5 treatments and 5 replication, each replication consisted of 5 sunflower seeds was irradiated by gamma ray of 0, 5, 25, 45, and 65 Gy. The data observed were analyzed by anova and followed with BNT of 5% level. Parameters observed included germination, plant height, stem diameter, tube flower diameter, tape flower diameter, initiation time, perfect bloom age, chlorophyll, ribbon flower number, seed number, total seed weight, weight of 100 seeds, LD50, Flower color and heritability. The result showed that irradiation significant effected to plant height, stem diameter, tube flower diameter, ribbon flower diameter, initiation time, seeds number, seed weight, weight of 100 seeds. Lethal doses of sunflower is 74,19 Gy. Heritability value range from 23,47 to 73,81%.Keywords : Helianthus annus L., irradiation, LD50, heritability

Abstract

The research aimed to increase the quality of manure to “Kotpi Plus” and to study the effect on growth and yield of sweet corn. The research used monofactor randomized block design with six treatments and 5 replications. The treatments were T0. Control; T1. 100% “Kotpi Plus” + 0% Urea and TSP (UT); T2. 75% “Kotpi Plus” + 25% UT, T3. 50% “Kotpi Plus” + 50% UT; T4. 25% “Kotpi Plus” + 75% UT; and T5. 0% “Kotpi Plus” + 100% UT. Parameters measured were plant height, leaf number, cob length, cob weight with cornhusk, and sum of seed row in a cob. Data were subjected to analysis of variance and followed by DMRT at α = 5%. The result on plant height and leaf number showed that T4 167.7 cm was significantly higher compared to control and 8.21 leaves significantly higher compared to control and T1, respectively. “Kotpi Plus” combined with inorganic fertilizer produced cob length significantly higher compared to control. Cob weight with cornhusk on T4 was significantly higher compared to T0 and T1. The given of “Kotpi Plus” fertilizer was not affecting on sum of seed row in a cob.

Abstract

The purpose of the research was to study the influence silica and concentration of NAA for moon orchid (Phalaenopsis amabilis L.) growth in acclimatization. The experiment was assigned in completely randomized factorial design with the first factor was silica (non silika and with silica) and the second factor was NAA concentrations (0, 50, 100, and 150 ppm). Each treatments was repeated three times. Parameters measured were the percentage of plant life, number of leaves,  length of leaf,  width of leaf, number of roots, length of root and fresh weight of plants. Data were subjected to ANOVA and followed by Duncan Multiple Range Test. The result showed that aplication silica increased fresh weight of plants. Application of NAA concentrations (50, 100, and 150 ppm) decreased percentage of plant life, leaght of leaf, and fresh weight of plants. Interaction of silica and NAA concentrations showed did not significantly effect. Keyword : Moon orchid, silica, NAA, aclimatization
