Inceptisol is a young and newly developed soil so it needs to be optimized for crop cultivation. The aim of this research is to know the availability of soil P, P uptake and corn yield after application of granular composting of sago waste (KGES) together with phosphate fertilizer to Inceptisols soil. The experimental treatment was KGES which consisted of three levels: without KGES, 40 tons KGES ha-1, and 80 tons KGES ha-1, and the use of SP-36 (P) fertilizer consisting of three levels: without P fertilizer, 120 kg P ha-1, and 240 kg P ha-1. The experiment used a complete randomized design with 3 replications. The result of the experiment was analyzed variance and relationship test using interlaced analysis. The results showed that KGES together with phosphate fertilizers could increase soil pH causing phosphate to be available and plant roots could absorb nutrient phosphate well, so that the yield of corn kiln dry weight also increased. The highest yield of dry weight of grains (7.85 tons per ha) was obtained from a combination of 80 tons of KGES ha-1 and 240 kg P ha-1.Keyword: Keywords: Ella Sago, Inseptisols, maize, phosphate

This study aimed to determine the effect of different biostimulant applications (solid and liquid) on the growth and yield of mustard plants. This study used a single factor Randomized Block Design (RBD), consisting of solid or liquid biostimulant treatment, each has twelve levels, i.e. K0 = without biostimulant, K1 = NPK 1 g per plant, solid and liquid biostimulant each consisting of 10 treatments = B1, B2, B3, B4, B5, B6, B7, B8, B9, B10. Solid biostimulant was given at 2.5 g per plant and liquid biostimulant at 10 ml per plant. The results showed that liquid biostimulant gave a significant effect on plant height, crop fresh weight, and crop dry weight; whereas solid biostimulant gave a very significant effect on entire weight, i.e. fresh weight of mustard plant, fresh root weight, and crop dry weight. The best treatment for liquid biostimulant was B1 treatment; whereas for the solid biostimulant was B7 treatment. Keywords: biostimulant, mustard, growth, yield   ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi biostimulan yang berbeda (biostimulan padat dan cair) terhadap pertumbuhan dan produksi tanaman sawi. Penelitian ini menggunakan rancangan acak kelompok faktor tunggal yang terdiri dari perlakuan Biostimulan (padat dan cair) yang masing-masing perlakuan terdapat dua belas taraf (P): K0 = tanpa biostimulan, K1 = NPK 1 g/tan, Biostimulan padat dan cair masing-masing terdiri dari 10 perlakuan = B1, B2, B3, B4, B5, B6, B7, B8, B9, B10. Biostimulan padat 2.5 g/tan dan biostimulan cair 10 ml/tan. Hasil penelitian menunjukkan bahwa biostimulan cair memberikan pengaruh yang nyata terhadap tinggi tanaman sawi, berat segar tanaman, dan berat kering tanaman, sedangkan biostimulan padat memberikan pengaruh yang sangat nyata terhadap semua bobot berat tanaman sawi yaitu berat segar tanaman, berat segar akar, dan berat kering tanaman. Perlakuan terbaik untuk biostimulan cair adalah perlakuan B1, sedangkan untuk biostimulan padat perlakuan yang terbaik adalah perlakuan B7. Kata kunci: biostimulan, sawi, pertumbuhan, produksi

This research was intended to determine the rate of Organic Soil Treatment (OST) and the interval of application of Landeto solution or their interaction on the growth of shallots grown in the regosol soil. This research was conducted in the green house of Departement of Soil Science, Faculty of Agriculture Gadjah Mada University. A Randomized Complete Block Design, employing a factorial treatment was chosen. The first factors was rates of OST, i.e,: 0, 3, 6, 9 and 12 ton ha?. The second factors was interval of application of Landeto Solution, i.e, : 3, 5 and 7 days. The combination treatments were repeated 3 times. Results of the research showed that; 1) Intermedien between rates of OST at 6 ton ha? and interval of application of Landeto solution ot 5 days, was found in bulb number per hills ( 29.87, cm2 ) respectively. 2) Application of OST, at 6 ton ha? had a significant effect on the plant fresh weight and the fresh bulb weigth, 3) Application of Landeto solution at different intervals had no significant effect on all components and crop yield.

Indonesia has a lot of germplasm diversity, one of which is the banana plant. Tongka Langit banana plant (Musa troglodytarum L.) is a type of banana endemic to eastern Indonesia, namely Maluku and Papua, which is quite unique. Morphological characterization is an approach used to identify a plant. In banana plants, characterization was carried out in the vegetative and generative phases which included the characters of leaves, stems, flowers and fruit. The method used in this research is a survey and direct observation at the research site. Based on the results of observations, it can be concluded that there is variation in the leaf character, while the flower and fruit characters for the two research locations show no variation
