Abstract

ABSTRACT Various doses of NPK fertilization  could increase plant growth. This research studied  the effect of NPK compound fertilizer with some kind of dose on the growth of seedlings of red jabon. This research was conducted at the Laboratory of Silviculture Faculty of Agriculture, University of Sam  Rarulangi which lasted from May until June 2012, The objectives of this study were to determine the effect of compound NPK fertilizers on the growth of seedlings of red jabon. The research used experimental design of Randomized Block Design (RBD), Each treatment was replicated 5 times and each replication consisted of 5 red jabon seedlings. The treatments being given were: (1) without fertilizer (control), (2) 1 g of NPK/ plant, (3) 2 g of NPK/plant, (4)  3 g of NPK/plant and (5) 4 g of NPK/plant.  The results of this research showed that compound fertilizer NPK influence to high growth, diameter,  number of leaves, root volume and dry weight of seedlings red jabon canopy. NPK fertilizer with a dose of 3 g/plant  (D) can increase height growth,  diameter and number of leaves. While the parameters of the root volume and dry weight of the canopy, NPK treatment media with 4 g/plant (E) gives better results.Keywords : NPK fertilization, growth seedling, red jabon ABSTRAK Pemupukan NPK dengan berbagai dosis dapat meningkatkan pertumbuhan tanaman.

Abstract

ABSTRACT Research on the Use of Multiple Types of Organic Materials with Different Application Times on Mustard (Brassica juncea L.) was conducted to study the effect of organic material source interaction and application time in improving the growth and yield of mustard and obtaining organic sources of materials and timing applications to improve growth and yield of mustard. Factorial research with two factors is designed using Group Random Design. The first factor was: source of organic material (A) consisted of: A1 = pig waste, A2 = cattle dung, A3 = rice straw. The second factor is application time (B) Time: B1 = 5 days before planting seedlings (SBTB), B2 = 10 days before planting seedlings (SBTB), B3 = 15 days before planting seedlings (SBTB) Each experimental unit is repeated three times there were 27 pot of experiments, the variables observed were: plant height, leaf number, leaf width, leaf length and weight of wet stratum. The data were analyzed using variance analysis and if there were difference followed by  Honest Real DifferenceTest at 5%. The results showed that effect of interaction between source of organic matter with different application time to the number of leaves, fresh weight, content of N, P, and K of soil after harvesting of mustard. Plant height and leaf length is singly affected by application time.  Source of organic material of cow dung and paddy straw at the time of application 10 and 15 days before planting seedlings give the best result on the number of leaves, fresh weight of mustard, N, P and K.Keywords: mustard, organic matter source, application time, organic fertilizer ABSTRAK Penelitian Penggunaan Beberapa Jenis Bahan Organik dengan Waktu Aplikasi yang Berbeda Pada Budidaya Tanaman Sawi (Brassica juncea L.) dilakukan untuk mempelajari pengaruh interaksi sumber bahan organik dan waktu aplikasi dalam meningkatkan pertumbuhan dan hasil sawi serta memperoleh sumber bahan organik dan aplikasi waktu yang tepat dalam meningkatkan pertumbuhan dan hasil sawi. Penelitian faktorial dengan dua faktor dirancang dengan menggunakan Group Random Design. Faktor pertama adalah: sumber bahan organik (A) terdiri dari: A1 = limbah babi, A2 = kotoran ternak, A3 = jerami padi. Faktor kedua adalah waktu aplikasi (B) Waktu: B1 = 5 hari sebelum penanaman bibit (SBTB), B2 = 10 hari sebelum penanaman bibit (SBTB), B3 = 15 hari sebelum penanaman bibit (SBTB) Setiap unit percobaan diulang sebanyak tiga kali Ada 27 pot percobaan, variabel yang diamati adalah: tinggi tanaman, jumlah daun, lebar daun, panjang daun dan berat lapisan basah. Data dianalisis dengan menggunakan analisis varians dan jika ada perbedaan yang diikuti oleh Jujur Real DifferenceTest sebesar 5%. Hasil penelitian menunjukkan bahwa pengaruh interaksi antara sumber bahan organik dengan waktu penerapan yang berbeda terhadap jumlah daun, bobot segar, kadar N, P, dan K tanah setelah pemanenan sawi. Tinggi tanaman dan panjang daun secara tunggal dipengaruhi oleh waktu aplikasi. Sumber bahan organik kotoran sapi dan jerami padi pada saat aplikasi 10 dan 15 hari sebelum penanaman bibit memberikan hasil terbaik pada jumlah daun, bobot segar sawi, N, P dan K.Keywords: tanaman sawi, sumber bahan organik, waktu aplikasi, pupuk organik

Factor II (B) = Phonska fertilizer, Consist of B1 = 25% Phonska, B2 = 50% Phonska, B3 = 75% Phonska, B4 = 100% Phonska. Each treatment was repeated three times to obtain 36 experimental plots. Response variables observed included: Plant dry weight, Length of cob, Cob diameter, Weight of cob, measured at harvest. Data were analyzed using variance analysis and if there was effect of treatment continued by using Test of Honest Real Difference (BNJ) at 5% test level. The results showed that the interaction between organic fertilizer formulation and NPK phonska significantly affect the diameter of cob and sweet corn cob weight. The dry weight of sweet corn plant is influenced by organic fertilizer formulation.
