Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pertumbuhan dan produksi Padi sawah varietas mekongga yang disebabkan oleh pengaruh olah tanah dan pemberian Pupuk N berdasarkan bagan warna daun. Di desa singali, Kecamatan Padangsidimpuan hutaim baru, Kota Padangsidimpuan. Dengan menggunakan Rancangan Spil Plot Desain dan tiga ulangan, parameter yang diamati dalam penelitian ini Pengukuran Warna Daun Padi Dengan BWD, Tinggi Tanaman, Jumlah Anakan, Umur Keluar Malai, Jumlah Malai, Jumlah Gabah Hampa Per Malai, Jumlah Gabah Isi Per Malai, Berat Gabah Per Seribu Butir, Produksi Per Plot. Pengukuran warna daun padi dengan BWD dimulai pada 21-28 hari setelah tanam (HST) kemudian secara berkala diulang setiap 7 -10 hari sekali sampai diketahui nilai kritis saat pupuk N harus diaplikasikan, sampai tanaman dalam kondisi bunting atau fase primodia. cara ini berlaku varietas unggul biasa. Khusus untuk padi hibrida dan pada tipe baru, pengukuran tingkat kehijauan daun tanaman dilakukan sampai tanaman sudah berbunga 10 %. Menurut hasil analisis sidik ragam pengamatan terhadap pengukuran warna daun Padi varietas mekongga dengan perlakuan olah tanah menunjukkan pengaruh tidak nyata pada umur 21 hst, dan umur 35 hst, Sedangkan pada perlakuan pemberian pupuk N menunjukkan pengaruh yang tidak nyata. Begitu juga pada interaksi kedua perlakuan tersebut menunjukkan pengaruh nyata.

Abstract

This study aims to determine the quality of coffee in several different geographical indications. This research was conducted at the Laboratory of the Faculty of Agriculture, University of Muhammadiyah South Tapanuli with a sampling method, namely sampling technique from 3 geographically indicated locations of coffee, namely Lintong Arabica Coffee, Mandailing Arabica Coffee and Sipirok Arabica Coffee. Observation parameters were altitude, water content, seed size and acidity (pH). Data analysis was carried out by analyzing the process hierarchy, correlation and concluded by descriptive method. Coffee quality is influenced by geographical indications, namely altitude. The highest water content is Mandailing Arabica Coffee and the lowest is Sipirok Arabica Coffee. The best bean size is Mandailing Arabica Coffee which has the highest size and the highest coffee acidity is Sipirok Arabica Coffee and the lowest is Lintong Arabica Coffee.

Abstract

This research program aims to determine the responsegiving organic fertilizer to the vegetative growth of robusta coffee plants (CoffeaCanephora). Using a 2 factorial Group Design (RAK), each treatment was given 3 replications. Factor 1 was liquid organic fertilizer for bamboo shoots (P0: control, P1: 200 ml + 1000 ml water, P2: 500 ml + 1000 ml water, and P3: 800 ml + 1000 ml water). Factor 2 is using vegetable compost (K0: control, K1: 10 grams/polybag, K2: 20 grams/polybag), K3: 30 grams/polybag). Parameters observed were plant height, number of leaves, stem diameter, and leaf width. Based on the data on the response variance of the application of liquid organic fertilizer (POC) for bamboo shoots, it was shown that there was no significant effect on the parameters of plant height, number of leaves, stem diameter, and leaf width at the ages of 2, 4, 6, 8, 10, 12 mst. The results of the response variance data for the application of vegetable compost showed no significant effect on the parameters of plant height, number of leaves, stem diameter, and leaf width at the ages of 2, 4, 6, 8, 10, 12 mst. And the results of the interaction of the two treatments showed no significant effect on the parameters of plant height, number of leaves, stem diameter, leaf width.

Abstract

This study aims to determine the effect of KNO3, H2SO4, and GA3 in breaking dormancy and germination of salak (Salacca zalacca) plants. In this study using a non-factorial randomized block design with one factor, namely P0 (control), P1 (KNO3 60%), P2 (KNO3 70%), P3 (KNO3 80%), P4 (H2SO4 60%), P5 (H2SO4 70%), P6 (H2SO4 80%), P7 (GA3 25 ppm), P8 (GA3 50 ppm), P9 (GA3 75 ppm), P10 (KNO3 60% and GA3 25 ppm), P11 (KNO3 70% and GA3 50 ppm), P12 (KNO3 80% and GA3 75 ppm), P13 (H2SO4 60% and GA3 25 ppm), P14 (H2SO4 70% and GA3 50 ppm), P15 (KNO3 60% and GA3 75). Parameters observed were germination, maximum growth potential, plant height, number of leaves, leaf length, and leaf width. Based on the results of the DMRT test at 5% level, it showed that each treatment had an effect on the chemical scarification treatment showing a significant effect on germination, maximum growth potential, plant height, number of leaves, leaf length, and leaf width. However, it did not have a significant effect on the number of leaves at 12 WAP, leaf width at 11 and 12 WAP. Keywords: Plant Height, Leaves, Leaf Width

Abstract

This research was conducted in Aek Nabara Village, Marancar District, South Tapanuli Regency. This study aims to determine the production of sap and palm sugar production based on differences in companion plants. Plant samples were taken from rubber companion plants, salak companion plants, cinnamon companion plants, durian companion plants, and cocoa companion plants. The highest sap production was found in sugar palm plants with durian companion plants, while the lowest sap production was found in sugar palm plants with rubber companion plants. The highest sugar production was found in palm plants with rubber companion plants, while the lowest sugar production was found in sugar palm plants with cinnamon companion plants.

Abstract

Tujuan penelitian ini adalah untuk mengetahui Pengaruh Pemberian Pupuk Organik Petrobio dan Beberapa Varietas Terhadap Pertumbuhan dan Produksi Tanaman Kacang Panjang (Vigna sinensis L). Penelitian ini dilaksanakan pada bulan Nopember 2020 sampai bulan Februari 2021. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) faktorial dengan dua factor yaitu : Faktor pemberian pupuk Organik Petrobio disimbolkan (N) terdiri dari 4 taraf yaitu : N0 = Kontrol, N1(1,5 cc /liter), N2 (2 cc /liter), N3 (2,5 cc/liter). Faktor beberapa varietas disimbolkan (V) ada  3 Taraf yaitu : V1(Varietas Bintang Asia), V2(Varietas Matahari), V3( Varietas Hijau Super). Dari hasil analisa secara statistik pada perlakuan pupuk organik petrobio tidak menunjukan pengaruh yang nyata terhadap tinggi tanaman, jumlah cabang pada umur 2 - 4 minggu setelah tanam, berat polong per sampel dan berat polong per plot pada pengamatan panen 1, tetapi berpengaruh nyata pada pengamatan panen 2 dan 3. Sedangkan  perlakuan beberapa varietas tidak menunjukan pengaruh yang nyata terhadap tinggi tanaman, jumlah cabang pada umur 2 - 4 minggu setelah tanam, berat polong per sampel pada pengamatan panen 1 dan 2, tetapi berpengaruh nyata pada panen 3 berat polong per plot. Dari hasil analisa secara statistik kedua perlakuan tidak menunjukan pengaruh yang nyata terhadap semua parameter yang diamati. Namun hasil terbaik dalam penelitian ini terdapat pada perlakuan pupuk organik petrobio yaitu pada berat polong per plot.
