ABSTRACT   This study used a randomized block design with five standard treatments as follows: A1 (15 days), A2 (20 days), A3 (25 days), A4 (30 days), A5 (35 days). The treatment was repeated three times. The purpose of this study was to obtain the best age of the seeds in order to obtain high growth and production. The results of statistical analysis showed that there was no siginifcant difference in the number of unproductive tillers 70 days after transplanting, but this was not the case for the leaf area index; 70 days after germination there was a significant difference. A1 treatment (15 days) had the highest LAI is 4, 56. The same result was shown in the weight of 1000 grains of rice where there was a significant difference among treatments; A1 treatment (15 days) weighted 31.12. It was concluded that the age of seedlings after transplanting had a significant effect on LAI and 1000 grain weight of rice grain after harvest. Keywords: Rice, seedling, transplanting ABSTRACT   Penelitian ini menggunakan rancangan acak kelompok dengan lima taraf perlakuan sebagai berikut : A1 (15 hari), A2 (20 hari), A3 (25 hari), A4 (30 hari), A5 (35 hari). Perlakuan diulang sebanyak tiga kali. Tujuan penelitian ini untuk mendapatkan umur bibit yang tepat sehingga diperoleh pertumbuhan yang tinggi. Hasil analisis statistika menunjukkan bahwa tidak terdapat perbedaan yang nyata pada jumlah anakan yang tidak produktif 70 hari setelah pindah tanam namun pada indeks luas daun 70 hari setelah berkecambah terdapat suatu perbedaan yang nyata, terlihat pada perlakuan A1 (15 hari) memiliki ILD tertinggi yaitu 4,56. Hal yang sama terlihat pada bobot gabah 1000 butir terdapat suatu perbedaan yang nyata antara perlakuan yaitu pada perlakuan A1 (15 hari) memiliki bobot tinggi yaitu 31,12. Disimpulkan bahwa umur bibit setelah pindah tanam sangat berpengaruh pada ILD dan bobot gabah 1000 butir padi setelah panen. Kata kunci: Padi, bibit, pindah tanam

A series of on-farm fi eld experiments were conducted in two locations in Padang, Koto Panjang and Koto Tingga, West Sumatera, Indonesia in 2015. The purpose of the experiment was to establish the formula of organic fertilizer derived from Tithonia supplied with micro nutrients, Zn and Mn, on rice. The experiments were conducted using completely-randomized block design with six treatments and three replications. The treatments were P = Tithonia Organic Fertilizer Plus (TOFP) + 3.0 kg Mn.ha-1, Q = TOFP + 3.0 kg Mn.ha-1+ 3.0 kg Zn.ha-1, R = TOFP + 4.5 kg Mn.ha-1 + 6 kg Zn.ha-1, S= TOFP + 4.5 kg Mn.ha-1+ 9 kg Zn.ha-1, T = TOFP only, U = 100% chemical fertilizer only. Treatment with micro nutrients as addition to TOFP (TOFP+ 3.0 kg Mn.ha-1 and TOFP+ 3.0 kg Mn.ha-1+3.0 kg Zn.ha-1) increased rice grain yield by 80 g per clump.

Two Factors

Rice is a rice-producing food crop which now plays an important role in economic life in Indonesia. Namely rice as a staple food is very difficult to replace by other staples. Among them are corn, tubers, sago and other carbohydrate sources. So that the existence of rice is now a top priority for the community in meeting the needs of carbohydrate intake that can be filling and is a source of primary carbohydrates that are easily replaced into an energy source. Rice as a staple food is consumed by approximately 90% of the total population in Indonesia for daily essential food (Saragih,2001). How to plant with the jajar legowo system has the advantage that the plants are on the edge so that optimal sunshine can cause plant productivity to be high, facilitate weed control and pests / diseases, use of fertilizer more effectively and the availability of empty space for regulating water channel circulation on land (Sirrapa, 2011). This research was conducted using Factorial Randomized Block Design (RBD) method, which consisted of two factors and each factor consisting of 3 levels repeated 3 times, namely: J1: Conventional,J2: Jajar Legowo 2: 1,J3: Jajar Legowo 4: 1. Factor II: Varieties with 3 levels, V1: Situ Bagendit, V2: Ciherang,V3: IR-64. Of the two factors 9 combinations of treatments were obtained and repeated 3 times. Data obtained from observations were calculated by analysis of variance with the Fisher test (-F test at the level of 5% and 1%), if there were significant differences, it would be followed by the Smallest Significant Difference test (LSD 5%). The treatment of the legowo 4: 1 row system and the ciherang variety (V2J3) produces a better value than other treatments.

High Production

Rice is the main staple food in Indonesia. The high needs of national rice must be balanced with the high production of rice crops. One of the efforts to increase the production of rice is the application of liquid smoke originated from agricultural waste, namely husk. The research was aimed to determine the effect of the application of husk liquid smoke on rice growth and production. The research used a single-factor randomized block design (RBD) with 5 treatments and 5 replications. The treatments consisted of several concentrations of liquid smoke : 0% (control), 0.5%, 1%, 2%, and 3%. This research employed several stages; land processing, seedling nursery, rice planting, applicating the liquid smoke, fertilizing, maintaining plants, and harvesting. The results showed that the application of husk liquid smoke significantly affected all observational parameters. On the parameters of rice growth and production, the application of 2% liquid smoke showed the best result. The plant height increased by 25.80% and the number of tillers increased by 49.70% compared to the control. The highest increase is in the number of grains per panicle and the weight of 1000 grains was 4,984% and 26.78% respectively.

The aim is to determine the optimum combination of inorganic fertilizer and organic materials for increasing the productivity of rice crop (Oryza sativa L.). The experiment was conducted in February- June 2015 in Kebadu, Sanggau, West Kalimantan, Indonesia. The study area was located at 00°0.08,785’N north latitude and 110°0.07,175’E east longitude with ultisol soil; the altitude is 32 m above sea level, rainfall level ranges between 185-267 mm month-1, and the solar radiation is 375.49- 452.58 cal cm-2 day-1. This study used a factorial randomized block design. The first factor was the inorganic fertilization (without fertilizer, inorganic fertilizer 50%, 100%, and 150%) and the second factor was the addition of organic materials (EM4 2 l ha-1, chicken manure 2 t ha-1, and manure 2 t ha-1 + EM4 2 l ha-1). Results showed that the application of chicken manure and a combination of chicken manure+EM4 could reduce the need for inorganic fertilizer NPK by up to 50% with productivity that ranged from 4.18-4.20 t ha-1; this is relatively similar to 100% and 150% inorganic fertilizer NPK, and can increase the harvest by up to 68% compared to the no-NPK inorganic fertilizer.

Research on "Study of Manure on Growth and Yield of White Glutinous Rice (Oryza Sativa L. var. Glutinosa)" has been carried out from November 11th, 2019 to March 2th, 2020 in Donoudan Village, Ngemplak District, Boyolali Regency, the height of the place around 150 masl and the type of soil grumusol. This study uses a Complete Randomized Block Design (RAKL) with a single factor consisting of 10 kinds of treatments and repeated 3 times. Consisting D0, A1, A2, A3, K1, K2, K3, S1, A2, A3. Obsevation was carried out by taking 8 sample plants at each treatment. Data from this study were analyzed with the Uji Duncan’s Multiple Range Test (DMRT) at 5%, the parameters observed included plant height, number of tillers per family, leaf color, panicle length of number of productive tillers, weight of grain harvest per plot, weight of grain harvest per clump, and weight of 1000 grains. The results of the research, it was shown that the application of manure affected the length of panicle, the number of productive tillers, the weight of dried grains per clump, the weight of unhulled rice per plot and the weight of 1000 grains. The use of chicken manure with a dose of 4,5 kg/plot gave the highest yield of grain weight per plot which was 1820,90 grams (8,67 tons/ha), had a significant effect with control without manure (increase of 38,73) but not significant effect by providing treatmen of cow manure and goat manure.
