PENGARUH TAKARAN BOKASHI FLY ASH TERHADAP PERTUMBUHAN DAN HASIL TANAMAN BABY LOBAK (Raphanus sativus L) Var. Greenbow

The research was conducted in the greenhouse Faculty of Agriculture, Winaya Mukti University Sumedang district, from April 2011 until June 2011, which is located at an altitude of 850 meters above sea level. The aim of research to study the effect of fly ash Bokashi on growth and baby yield of rapeseed varieties Greenbow. The design used in the study is a randomized block design, which consists of five treatments and five replications. Treatment trial is dose flay ash Bokashi, which is 0 tonnes ha-1, 5 ton ha-1, 10 ton ha-1, 15 ton ha-1 and 20 ton ha-1. The results showed that the fly ash Bokashi effect on plant height, number of leaves per plant, diameter and weight of sweet potatoes per plant. Award dose Bokashi fly ash 5 ton ha-1 showed equally good results by administering doses of fly ash Bokashi 10 ton ha-1, 15 ton ha-1 and 20 ton ha-1 on plant height, leaf number, diameter and weight of tuber turnip var. Greenbow, so enough with a dose of Bokashi fly ash 5 ton ha-1 can give good results for plant radishes var. Greenbow

MIKROORGANISME LOKAL DALAM PENGOMPOSAN PADA MUTULOBAK VAR. GREENBOW YANG DIPANEN BERBEDA

The use of local microorganisms in the composting process will influence the final outcome compost or different according to the dominant species of microorganisms contained in the local microorganisms. This indirectly will respond differently to the growth and quality of radish tubers produced. Formulation of the problem of the research is as follows: How is the interaction between the use types of microorganisms locally in the process of composting organic material and harvesting time in the cultivation of rapeseed for the quality of radish, what type of microorganisms local and harvest time how many days after planting gives the crop rapeseed best. The research was conducted in the greenhouse of the Faculty of Agriculture, Winaya Mukti University. Experimental approach using experimental design factorial randomized block design consists of the first factor of compost a wide treatment with different local microorganisms, consists of five levels, and the second factor of different harvesting time which consists of four levels that are repeated twice. The results showed local Microorganisms snails on composting give significantly different results on the length and weight of tuber tubers radish Var. Greenbow, while the quality of radish tubers obtained from harvesting time at the age of 53 HST

Pengaruh Perbandingan Komposisi Media Tanah Pasca Tambang dengan Pembenah Tanah Faba terhadap Kemasaman Tanah dan Pertumbuhan Land Cover Crop (Pueraria javanicum)

The higher the use of coal in the industry, the higher the waste produced. This causes environmental problems such as air, soil, water pollution and a decrease in the quality of ecosystems and public health in industrial environments. For this reason, it is necessary to make efforts to utilize coal waste so that unwanted things do not occur, one of which is by using coal ash waste as a soil repairer to improve soil quality in post-mining land. This experiment was carried at the Faculty of Agriculture screenhouse, Winaya Mukti University, Tanjungsari, Sumedang Regency on the altitude of 850 M above sea level. The trial period is from Jully to August 2020. The experiment aims to determine the effect of comparisons of post-mining soil media composition with Faba fixer on the value of growth of Pueraria javanicum plants. The experimental design used was a randomized block design (RBD) which consisted of five treatments and was repeated five times. Treatment is the ratio of Fla Ash Bottom Ash soil repairer and post-mining soil with the following dosages; A = 100% post-mining soil, B = 25% Faba soil repairer + 75% post-mining soil, C = 50% Faba soil repairer + 50% post-mining soil, D = 75% Faba soil repairer + 25% post-mining soil, E = 100% Faba soil repairer. The results showed that treatment C (50% Faba soil repairer + 50% soil) had a good effect on plant height and shoot wet weight, treatment D (75% Faba soil repairer + 25% soil) had a good effect on the number of leaves, root length, number of effective nodules, and root wet weight of Pueraria javanicum plants.

Pengaruh Dosis Amelioran dan Umur Panen terhadap Hasil Benih G1 Kentang (Solanum tuberosum L.) Varietas Medians

The purpose of this study was to study the effect of amelioran dose and harvest age on the yield of G1 potato varieties of Medians. This research was conducted in the experimental garden of the Faculty of Agriculture, University of Winaya Mukti, on Inceptisol soil with an altitude of 850 meters above sea level. The experiment was carried out from February to June 2021. The experimental design used was a Randomized Block Design consisting of nine combinations of amelioran treatments and harvest age, namely A (Amelioran 0 tons ha-1 + harvest age 90 days), B (Amelioran 0 tons ha-1 + harvest age 100 days), C (Amelioran 0 tons ha-1 + harvest age 110 days), D (Amelioran 10 tons ha-1 + harvest age 90 days), E (Amelioran 10 tons ha-1 + harvest age 100 days), F (Amelioran 10 tons ha-1 + harvest age 110 days), G (Amelioran 20 tons ha-1 + harvest age 90 days), H (Amelioran 20 tons ha-1 + harvest age 100 days), and I (Amelioran 20 tons ha-1 + harvest age 110 days) each treatment was repeated three times. The results of the experiment showed that the ameliorant dose and harvest age had an effect on the number of tubers, the weight of the tubers planted, and the G1 potato seed class. Dosage of ameliorant 10-20 tons ha-1 and harvest age of 90-110 days gave better yields of potato G1 seeds

Pengaruh Jenis Bakteri Pelarut terhadap Pertumbuhan dan Hasil Benih G3 Kentang (Solanum tuberosum L.) Varietas Medians.

This article aims to examine the effect of phosphate solubilizing bacteria (PSB) on the growth and yield of G3 seeds of potato (solanum tuberosum L.) varieties of medians. The experiment was conducted in the experimental garden of The Faculty of Agriculture of Winaya Mukti University Tanjungsari, Sumedang with a height of 850 meters above sea level with the order of land Andisol. Time trials are conducted from May to August 2019. The design used is a simple RandomIzed Group Design consisting of five types of phosphate Solubilizing bacteria, namely without PSB, Pseudacidovorax intermedius, Agrobacterium fabrum, Agrobacterium tumefaciens, Serratia nematodiphila and repeated five times each. The results of the experiment showed that the administration of this type of PSB was able to increase the height of the plant and the number of leaves at the age of 28 DAP and 42 DAP and give the result of the number of potatoes and the weight of the perpetak tubers on the potato crop of the medians varieties better

Composition and dose of ameliorant against C/N ratio, soil PH, plant phosphate content on potato plants

This article aims to learn the addition of ameliorant material on the ground so as to increase the level of soil fertility especially for the potato plants that are buenabled on the medium plains. The experiments were conducted on medium plains with a height of 750 m above sea level in Jatinangor area, Indonesia with land type Incepticol. The composition of ameliorant consists of chicken manure, coconut shells and dolomite biochar. The seeds of the potatoes used are relatively good varietal when cultivated in a medium plain. The design of the environment used is the group's random draft repeated 3 times, the treatment design consists of K0: control; K1: Cattle manure 10 ton ha-1; K2: Cattle manure 20 ton ha-1; K3: Cattle manure 8 tons ha-1, dolomite 1 ton ha-1, 1 ton ha-1 biochar; K4: Cattle manure 16 tons ha-1, dolomite 2 ton ha-1, 2 ton biochar ha-1, K5: Cattle manure 8 tons ha-1, dolomite 2 ton ha-1; K6: Cattle manure 16 ton ha-1, dolomite 4 ton ha-1; K7: Cattle manure 8 tons ha-1, biochar 2 ton ha-1; K8: Cattle manure 16 ton ha-1, biochar 4 ton ha-1. Results showed that the composition and dose of ameliorant able to increase the value of soil pH, but have not been able to improve the C/N ratio and absorption of phosphorus plants. Best result obtained from the treatment of Cattle manure composition 16 ton ha-1, dolomite 2 ton ha-1, 2 ton ha-1 biochar. Soil pH is capable of increased by 16.83% and the size of the potato bulbs of Class L (450-550 mm) amounted to 35, 11%, size M (350-450 mm) by 25.89% and size S (200-350 mm) amounting to 34.37% when compared with control
