Abstract

Research was conducted in Limau Manis, Padang City of West Sumatra. Theexperimental design used was a non-factorial randomized block design. Job’s tears used in this study is a cultivar of beras. The research objective was to determine the effect of various levels of population density on job’s tears growth in sub-optimal area. The density of the population used in this study is that A1 = 62,500 plants / ha (spacing of 40 x 40 cm), A2 = population of 50,000 plants / ha (spacing of 50 x 40 cm), A3 = 40,000 plants / ha (spacing 50 x 50 cm), A4 = 33,333 plants / ha (spacing 50 x 60 cm), A5 = 28,571 plants / ha (spacing 50 x 70 cm), A6 = 25,000 plants / ha (spacing 50 x 80 cm), A7 = 22,222 plants / ha (spacing 50 x 90 cm), and A8 = 20,000 plants / ha (spacing 50 x 100 cm). The results showed that the density of the plant population that was too dense had an effect on the decline in several growth components but showed the highest average ILD value. Whereas treatment with population density that was not too high or by using spacing that was tenuous gave the best effect on the variables of plant height, number of tillers and number of leaves. Further observations are needed to determine the effect of the treatment given on theyield components.

Abstract

The conversion of fertile land into industrial areas and construction development has contributed to the decline of rice production in Indonesia. Therefore, it is necessary to expand the rice fields to the sub-optimal land, i.e. lands with high levels of Fe and Al and low soil pH. One of the solutions that can potentially solve the problem is choosing varieties of rice that can adapt to the suboptimal land environment; the rice varieties can be obtained by estimating rice genetic parameters and selecting the optimal planting methods. One method that can potentially improve rice yield is “System of Rice Intensification”, or SRI method. Our study was conducted in the rice fields on suboptimal land at Pasar Ambacang, Kuranji District, Padang, Sumatra, from December 2019 to April 2020. The aims of the experiment are to determine the genetic parameters and responses of the three rice varieties to suboptimal land using the SRI method. A complete randomized design with four replications was used to set up the experiment using three varieties of rice, i.e. “Batang Piaman”, “Bujang Marantau”, and “IPB3S”. Based on the plant growth measurement and analysis of the genetic parameters, we found that the plant growth characters, particularly height and panicles length, had high heritability and genetic progression values.

Abstract

Hanjeli is one of the alternative food crops that are high in nutrients, healthful, easy to grow, and adaptable to a wide range of environmental circumstances. Due to the limited understanding of people who believe Hanjeli is a wild plant or weed, usage of this commodity is still quite low in Indonesia. To save and prevent the loss of genetic resources, it is vital to study, inventory, and characterize Hanjeli so that plant breeders can use it to create greater varieties in the future. The goals of this study are to: (1) learn about the existence and types of Hanjeli plants in West Sumatra Province; (2) collect Hanjeli germplasm; and (3) learn about the morphological diversity and level of similarity of Hanjeli plants as a starting point for germplasm conservation of Hanjeli plants in West Sumatra. This study took place in four districts/cities in West Sumatra Province from June to November 2021. This study is carried out using a survey method with purposive sampling. The NTSYSpc2.02i application is used to present morphological data descriptively and for similarity analysis. 69 Hanjeli accessions were discovered throughout the exploration process. Hanjeli grows between 6 to 1575 meters above sea level and can thrive in a variety of environments, including arid ground and regions near water sources (starting on the outskirts of streams to the edges of rice fields). For all characters, the phenotypic similarity study of Hanjeli plants yielded similarity coefficients ranging from 0.67 to 1. At 0.67, the accessions were divided into two groups: 66 accessions in the first group, and 3 accessions in the second group.

Abstract

Aprisal. et al. Dynamics of Some Physical Properties of Soils Under Conservation Farming System on the Critical Land Aripan in the DTA Singkarak. JLSO 5(2):137-144.The conservation farming on critical land can improve the soil properties and maintantain for a periode of time. The purpose of this research is to study the dynamics of critical land’s physical characteristics under the influence of conservation farming at Singkarak Water Catchment Area (DTA) in Nagari Aripan. The analysis of soil sample is conducted in Soil Science Department Laboratory, Faculty of Agriculture, Andalas University. This research is designed with Split Plot Design (RPT). The main plot is a soil processing system which is: conventional soil processing (po), soil processing with mulch (p1), soil processing with compost and manure (p2) and minimum soil processing (p3), while the sub plot consists of three types of plants, they are; sweet corn (t1), soy bean (t2) and peanut (p3). Each treatment is repeated three times. Result of the research is observation data in each season of the first, second and third year. To see the dynamics of soil characteristics, data of each season is viewed through graphic which based on its trend. The result of the research indicates that utilization of critical land with conservation farming system could repair and maintain some physical characteristics of soil in each growing season, such as: decreasing volume, increasing soil organic matter, porosity, and soil permeability. Productivity of soil increases on the conventional processing with mulch, compost, and manure. Conventional soil processing with added compost and manure increases productivity for 32.58% in the first year, 45.16% in the second year, and 59.73% in the third year.

Abstract

Potato (Solanum tuberosum L.) is of important major crops for its carbohydrate and plays important roles to support food sovereignty along with rice, wheat, corn, and sorghum. Potato growth and yield at West Sumatra has not reached its maximum potential due to some factors including cultivation. One major important constraint in potato growing in West Sumatra is the fact that farmers use the 8th to 12th generation of potato seedlings which have a very low agronomic potential. Yet, weeds have caused another problem in the field and reduce potato yield. An experiment has been conducted at the Laboratory of Microbiology, Faculty of Agriculture, Universitas Andalas and Nagari Alahan Panjang, Subdistrict Lembah Gumanti, Solok Regency from November 2018 to March 2019. The experiment was aimed at determining the best indigenous rhizobactria isolates to increase the growth and yield of potato plants as well as weed population dynamics associated with potato plants. Six isolates of indigenous rhizobacteria and a control treatment group were tested in a completely randomised design with three replicates. The isolates were L1 S3.1, L1 S3.2, L1 S4.4, L2 S1.2, L2 S2.3, L2 S3. 2. Data were analyzed with analysis of variance and mean separation with Duncan's New Multiple Range Test (DNMRT) at 5%. Results showed that isolate L1 S4.4 was best in increasing the number of branches, number of tubers, and weight of potato yield. The isolates tested affected weed populations dynamics, prior to treatments there were 8 species of weeds found at the field i.e Bidens pilosa L., Leptochloa chinensis, Eleusine indica L., Agerathum conyzoides, Richardia sp, Galinsoga parviflora, and Sonchus arvensis. During potato growing at the field, weed species of Eleusine indica L. and Gynura divaricata dissappeared from the soil. In contrast,  Amaranthus spinosus emerged demonstrating that weed population dynamic has occurred.

Abstract

The Effect of Rhizobacteria Types and Arbuscular Mycorrhiza Fungi to Potato Yield (Solanum tuberosum L.). Production and productivity of potatoes (Solanum tuberosum L.) in Indonesia is still relatively low compared to other countries. The research aimed to study the effect of interaction between rhizobacteria types and arbuscular mycorrhiza fungi to potato yield. The research was conducted in Laboratory of Microbiology, Faculty of Agriculture, Andalas University and Balai Pengkajian Teknologi Pertanian Sumatera Barat from October 2017 to March 2018. Factorial design with 2 factors in block randomized design was used in the research. The first factor was rhizobacteria isolates (no rhizobacteria, RZ1.L2.4, RZ1.L2.1 and RZ2.L2.1). The second factor was Arbuscular mycorrhiza fungi (AMF) doses (5 g/plant, 10 g/plant and 15 g/plant). The results showed that the interaction between rhizobacteria and AMF did not affect the yield components of potato. The best rhizobacteria isolate was RZ2.L2.1 and 15 g/plant was the best AMF dose for fresh weight of tuber per plant, per plot and per hectare.Keywords: potato, Arbuscular mycorrhiza fungi, rhizobacteria, Solanum tuberosum LABSTRAKProduksi dan produktivitas kentang (Solanum tuberosum L.) di Indonesia secara nasional masih tergolong rendah dibandingkan dengan negara lain.

Abstract

The majority of Lambung Bukik Village people, Pauh Subdistrict, Padang City, make a living from farming horticultural crops, secondary crops, forest plants (Sungkai and gaharu) and raising cattle and chickens. The Sungkai Permai Farmer Group has a 2-5-year-old gaharu tree, the seeds obtained through the Elok Nagari CSR activities of PT Semen Padang. Currently, the agarwood tree has good potential through the inoculation of fungal pathogens on the agarwood tree to form economically valuable sapwood and the use of its leaves as a health drink. This activity aims to: 1). the community knows how to cultivate agarwood plants, know its benefits, and know-how to process parts of the agarwood tree, such as sapwood and leaves, into raw materials for tea drinks, 2). provide special skills for farmer groups members so that they are expected to be used as independent businesses; 3). They empower the community in utilizing empty land through the cropping pattern of aloes agroforestry with plantation crops, 4). as a form of community activity from Andalas University, especially the Faculty of Agriculture. This activity was carried out in the Sungkai Permai Farmer Group, Lambung Bukik Village, Padang City. The Sungkai Permai farmer group has acquired knowledge about gaharu cultivation and tea use through participatory methods and training in the form of demonstrations and demonstration plots by planting approximately 150 gaharu seeds as raw material for tea through an agroforestry pattern. The Sungkai Permai farmer group has acquired knowledge of using the part of gaharu to become aloe tea as a drink and health medicine from the leaves and sap of aloes. The Sungkai Permai farmer group can manage raw materials for gaharu leaves and sap derived from gaharu trees around farmers' land in Limau Manis sub-district, or other areas. They can be a productive business opportunity as tea and medicine in health drinks to improve the community's economy.
