Abstract

West Sumatra is one producing coffee area in Indonesia a significant contribution to economy in Indonesian, because production coffee in West Sumatra unstable, it is necessary to expand the area. The propagation plants coffee is carried out in generative manner and needs be optimized with treating gibberellin hormone and water temperature to germination stage of coffee seeds.This research was conducted at the Seed Technology Laboratory of the Faculty of Agriculture, Andalas University from May to August 2021. The parameters observed were initial seed weight (g), seed weight after treatment (g), initial seed moisture content (%), seed moisture content after treatment (%). The results showed that the observation of initial seed weight and initial seed moisture content showed no significant effect. While the data had a significant effect on the observation of seed weight after treatment with the concentration of gibberellin hormone and seed moisture content after treatment in the treatment of water types, where the observation of seed weight after the highest treatment was in the treatment of gibberellin hormone concentration of 400 ppm with aquadest (G4J1) of 4.23 g and on the observation of the water content of the seeds after the highest treatment, namely the treatment with the concentration of the hormone gibberellin 300 ppm with aquadest (G3J1), which is 46.32%. Key words: Seed Weight, Moisture Content, Aquadest

Abstract

The increase in market demand red spinach (Amaranthus Gangeticus) makes the prospects very promising less than optimal for the growth of red spinach (Amaranthus Gangeticus) because soil fertility is low so that the provision of organic material can improve soil fertility through the improvement of the physical, chemical, and biological soil so that it can support the growth of red spinach. This study aims to determine the dose of manure, the dosage of rice husk ash as well as the interaction of dosage that is optimal for the growth and yield of red spinach.this research was conducted experimental farm of the faculty of science and technology with a height of 28 meters above sea level Labuhanbatu district in March to October 2020. Research design using group factorial consisting of two factors. The first factor, namely the granting of cow manure (L) with three levels, namely : L0 = 0 ton/ha (control) L1 = 2 ton/ha, equivalent to 200 g/m2 (the recommended dose), L2 = 4 ton/ha, equivalent to 400 g/m2, L3 = 6 ton/ha, equivalent to 600 g/m2. The second factor, rice husk ash (A) consists of 4 levels, namely : A0 = 0 ton/ha (control), A1 = 1 ton/ha equivalent to 50 g/m2 (the recommended dose), A2 = 1.5 tons/ha, equivalent to 75 g/m2.The Parameters measured were plant height (cm), number of leaves (strands), Weight per Plant Sample (g). The results showed that the administration of cow manure 4 ton/ha, equivalent to 400 g/m2 can increase plant height, leaf number, and weight per Plant of amaranth red. The provision of 1.5 tons/ha, equivalent to 75 g/m2 can increase plant height, the number of leaves plant red spinach (Amaranthus Gangeticus).Keywords: Rice Husk Ash, Red Spinach, Cow Manure, Plant Growth

Abstract

Land evaluation is useful as a basis for sector development in an area that is useful for reorganizing existing land use so as to assist in making land use planning decisions. Peanuts have great potential to be cultivated and developed commercially because they have wide adaptability, high productivity, are resistant to plant pests and are more resistant to marginal conditions. This research is descriptive with survey methods. The sampling method used is based on land map units with a free grid system for data. climates classified by climate type Schimdt and Ferguson. Land evaluation was carried out using the matching method by matching and comparing land characteristics with land suitability class criteria so that to obtain land suitability classes for peanut plants in Rantau Selatan District, Labuhanbatu Regency, there were 6 sample points so that the determination of soil characteristics values for soil samples was carried out using a soil drill tool. at a depth of 0-60 cm. Research results for peanut plants in Pardamean Village, Rantau Selatan District according to marginal / S3. Land suitability for peanut plants cultivated in Rantau Selatan District Labuhanbatu Regency 2.017 ha. The actual land suitability class for peanut plants is Nwa, while the potential land suitability class is S2tcwa. Keywords: Land Evaluation, Peanut Plants, Rantau Selatan, Labuhanbatu

umatera Barat merupakan provinsi penghasil kopi di Indonesia. Luas areal perkebunan kopi pada tahun 2016 sampai 2018 yakni 38.365 Ha; 33.276 Ha; dan 34.024 ha dengan produksi 22.721 ton; 17.553 ton; dan 18.026 ton. Buah kopi harus ditangani secara cepat menjadi bentuk yang lebih stabil agar aman untuk disimpan dalam jangka waktu tertentu. Kriteria mutu biji yang meliputi aspek fisik, cita rasa dan kebersihan serta aspek keseragaman dan konsistensi sangat ditentukan oleh perlakuan pada setiap tahapan proses produksinya. Penelitian ini dilaksanakan di Laboratorium Teknologi Benih Fakulltas Pertanian Universitas Andalas dari bulan Agustus 2020. Pelaksanaan penelitian ini digunakan bahan antara lain benih kopi robusta yang diambil di daerah solok, Alat yang digunakan dalam penelitian ini adalah meteran, botol-botol plastik, pisau, timbangan analitik, beaker glass, gunting, karung goni, ember, kamera, sarung tangan, masker dan alat tulis. Penelitian ini dilakukan secara deskriptif yakni mengambil beberapa sampel buah tanaman kopi robusta dan mengamati perubahan fisik dari buah yang diambil secara random disuatu areal perkebunan kopi robusta.

Abstract

Brassica juncea is one of vegetable consumed by many people. One of the ways to expand genetic diversity is by inducing the occurrence of mutations. Mutations can be induced by offering chemical mutagens as well as physical mutagens. One of chemical have been successful to induce mutation is colchicine. The aim of this research was to determine effect of colchicine on Brassica growth. This research was conducted in June 2019 in the Experimental Field, Labuhanbatu University. The result show that soaking brassica seeds using colchicine make a decrease in the average plant height, leaf widht and number of leaves compare to control cause abnormal cell division.

Abstract

The plants acquire phosporus from soil solution as phosphate anion. The availability of nutrients is very low in soil and crops compared to the other macronutriens. It precipitates in soil as orthophosphate or absorbed by Al and Fe so that inhibiting the plant growth. Phosphate solubilizing bacteria are able to release the P bond of clay minerals and provide it for crops. The research aimed to get phosphate solubilzing microbes from maize (Zea mays L.) rhizosphere. The soil samples were taken from the maize rhizosphere in both the vegetative and generative phases in the Cikabayan Bogor experimental farm. The phosphate solubilzing bacteria were determined for its ability to dissolve phosphate in liquid Pikovskaya media. The results of research were obtained 16 phosphate solubilizing bacteria, each of the 12 isolates derived from maize rhizosphere in vegetative phase (JM FIO) and 4 isolates in generative phase (JT FIO). The phosphate solubiliton index of each phosphate solubilizing bacteria was varied, namely 2,2-4, the largest dissolution index obtained at JM FIO 1. The largest phosphate dissolving ability in liquid Pikovskaya media was showed by JM FIO 3 isolate, P value was 0,60 ppm or increased 300% of control then followed by JM FIO 9 with 0,43 ppm P. The research also showed that JM FIO 3 and JM FIO 9 were not pathogenic and potentially could be used as biological fertilizer with number of cells at each 4.2 x 109 and 1.2 x 109 CFU/g of carrier.Key Words : Phosphate Solubilizing Microbe, Maize, Rhizosphere

Abstract

Sago is a plant produces high carbohydrate source. The problem of sagoo propagation by generative are limited number of seeds and low germination. Vegetative propagation of sago can be done through sago tillers, however, the very slow root growth will affect the ability of the sago to survive. One way to accelerate root growth is by administering IBA growth regulators. This study aims to determine the response to the growth of sago saplings by immersing IBA (0, 25, 50, 75) ppm. The results showed that the highest percentage of living plants was found in the 25 ppm IBA immersion treatment with the percentage of live tillers 88.89%. For the parameters of the number and length of roots and the highest plant height was also found in the 25 ppm IBA immersion treatment with an average number of roots of 6.7, 12.43 cm of root length and an average plant height of 49 cm.
