Get PDFResearch with the aim to determine the Effect of Concentration and Botanical Incecticide (neem leaf) On the Yield of Soybean (Glicine max, L Merrill) Variety Grobogan, have been performed in Kalurahan Ledok, Argomulyo, Salatiga. The research method used was a factorial study method RAKL (Completely Randomized Design) with 12 combinations of treatments and 3 replications. As for the treatment factor K0: Without treatment (control) K1: neem leaf extract 150 ml / liter, K2: neem leaf extract 300 ml / liter. Spraying intervals A1: 30 days (30,37,44,51), A2: age 37 days (37,44,51,58), A3: age 44 days (44,51,58,65), A4: age 51 days (51,58,65,72). The result study showed that the concentration of neem leaf treatment was not significantly different in plant height, stover fresh weight, dry stover weight, seed weight per plot and weight of 100 dry seeds but significant reducing the intencity of pests and the percentage of infected plants. The best results on the highest weight of 100 seeds on KOA4 (20.156 g), seed weight per plot K2A1 (546.67 g

The purposes of this study were to determine the effect of organic fertilizer residues and addition of urea fertilizers in improving soil fertility in the C excavation paddy soil and the yield of corn (Zea mays, L). Research was conducted by using completely randomized design (CRD) single factor, consisting of six treatments, as follows, P0: Control, residue treatment of : inorganic fertilizer (P1), Cow manure (P2), Bokhasi fertilizer (P3), manure and inorganic fertilizer (P4), Bokhasi and inorganic fertilizer (P5). Urea fertilizer was added a quarter of recommended dose for each treatment residue. It was given twice, except for the control treatment, and repeated 4 times, and placed randomly. Observations of soil chemical properties comprising: soil pH, C-organic, BS, CEC and the N-total crop land, while parameters of the plants, including components of the growth and yield of corn, were also observed. The results showed that the residue of organic fertilizer and the addition of urea fertilizer were able to increase the fertility of the C-excavation paddy soil. It has been proved by the growth and yield of corn were increased, such as plant height, fresh and dry weight of plant, weight and girth of the highest cob. Residual treatment obtained from the treatment of organic and inorganic fertilizer showed significantly different with the addition of urea fertilizer, as compared to control, however it showed not significantly different to other treatments

Efficiency of Nitrogen And Phosphorus Fertilizer With Vesicular Arbuscular Mycorrhiza (VAM) Application In Yield of Situbagendit Rice Variety On Rainfed Lowland Rice
Get PDFThe area of rainfed lowland rice in Indonesia was 3,292,578 ha or 24% of the total area of rice, but the used is still very small, so that opportunities are still open for the development of rice plants. The main constraints on rainfed lowland are drought stress and inefficient use of nitrogen (N) and phosphorus (P) nutrients. The purpose of this study was to determine the effect of mycorrhizal fungi on the efficient use of nitrogen and phosphorus in rice planted in rainfed lowland. This research was conducted in rainfed lowland in April to July 2019 in the village of Demangan, Sambi, Boyolali, Central Java. The research method was a randomized completely block design. Factor 1: Doses of nitrogen fertilizer (N) 0; 45; 90; 135 kg/ha. Factor 2: phosphorus dose (P) 0; 25; 50; 75 kg/ha. Observations included the number of total tillers, number of productive tillers, panicle number, panicle length, 1000 grain weight, and grain weight per plot. Data Analysis was analysis of variance. If there was a difference between treatments then it was tested further by using Duncan's New Multiple Range Test at 5% level. To know the relationship of direct and indirect influence, regression and correlation analysis were done. Data were analyzed by computer using SAS for window 9.0 programs. The results showed that the application of VAM could save the use of nitrogen fertilizer and eliminate the use of phosphorus fertilizer
KARAKTER PERAKARAN DAN HASIL BERBAGAI VARIETAS PADI SAWAH (Oryza sativa L.) DENGAN APLIKASI MIKORIZA PADA LAHAN SAWAH TADAH HUJAN
Get PDFPadi (Oryza sativa L) merupakan komoditas pangan yang sangat penting peranannya dan menjadi komoditas utama pangan di indonesia. Salah satu upaya untuk meningkatkan produksi padi melalui teknik budidaya padi dengan menambahkan mikoriza pada tanaman. Akar adalah bagian terpenting pada tanaman yang berada didalam tanah dan memiliki peran yang sangat penting dan menyerap air dan unsur hara. Penelitian ini bertujuan untuk mengetahui pengaruh mikoriza terhadap karakter perakaran dan hasil varietas padi sawah yang dibudidayakan pada lahan tadah hujan. Penelitian ini dilaksanakan pada bulan Januari 2018 sampai dengan Juli 2018 di di desa Demangan, kecamatan Sambi, kabupaten Boyolali. Dengan lahan sawah tadah hujan dan ketinggian tempat 130 mdpl dengan jenis tanah Regosol dan Laboratorium Ilmu Tanah Fakultas Pertanian Universitas Tunas Pembangunan Surakarta dan di Laboratorium Ilmu Tanaman Fakultas Pertanian Universitas Gadjah Mada Yogyakarta. Penelitian ini menggunakan Rancangan Acak Kelompok Lengkap (RAKL) yang disusun secara Split Plot dengan dua faktor yaitu mikoriza sebagai main plot dan varietas sebagai sub plot dan diulang tiga kali dengan taraf mikoriza sebagai berikut ; M0 : tanpa mikoriza, M1 : dengan mikoriza dan varietas dengan taraf sebagai berikut ; V1 : varietas situbagendit, V2 : varietas pepe, V3 : varietas mentikwangi, V4 : varietas way apo buru, V5 : varietas memberamo, V6 : varietas mekongga, V7 : varietas IR 64, V8 : varietas inpari13. Hasil penelitian ini menunjukkan bahwa : (1) perlakuan penggunaan mikoriza pada tanaman padi menunjukkan berpengaruh berbeda nyata terhadap panjang akar, luas permukaan, berat segar dan kering akar, berat kering tanaman dan berat gabah kering panen/petak. (2) Perlakuan berbagai varietas tanaman padi merupakan cara untuk mengetahui varietas terbaik. Varietas yang terbaik adalah varietas memberamo karena dapat terinfeksi mikoriza dengan sangat efektif. (3) Hasil tertinggi berat gabah kering panen/hektar terdapat pada M1V1 dengan perlakuan dengan mikoriza varietas memberamo dengan berat 3.725 kg, dan hasil terendah berat gabah kering panen/petak terdapat pada M0V7 dengan perlakuan tanpa mikoriza varietas IR 64 dengan berat 1.956 kg

No full textHeavy metal contaminants in land agriculture are environmental problems, and they affect food safety, so there is a need for the research of Pb, Cd and Cu decrease absorption by plants using organic chelating agent, i.e. substance of humus (humic and fulvic acid) in the manure. The research was done with a completely block design, in Gagaksipat, Ngemplak, Boyolali; heavy metal analysis in manure, land and seeds used an atomic absorption spectrophotometer-flame (AAS Jena Contr AA 300, Germany). It was aimed to identify contaminants of Pb, Cd, and Cu in sweet corn and soybean seeds. The research treatments were doses of cow manure: 15, 20, 25, 30, 35, 40, 45 and 50 kg per hectare. The results showed that the enrichment coefficient (EC) of Pb and Cu in sweet corn seeds had low accumulator plants categories; the EC of plumbum in soybean seeds had low accumulator plants categories, whereas the EC of copper soybean seeds had moderate accumulator plants categories; and the EC of cadmium in the sweet corn and soybeans seeds was undetectable. Exposures of Pb and Cd in corn sweet and soybean seeds were undetectable, while exposures of Cu in sweet corn and soybean seeds were 2.03 and 12.39 ppm, respectively. Contamination of Pb, Cd and Cu exposures in land after sweet corn harvested were 30.99; undetectable and 60.58 ppm, respectively. While Pb, Cd and Cu residues in land after soybean harvested were 33.24; undetectable and 56.26 ppm, respectively
