Abstract

This study aims to obtain the composition of soil and cow dung that provides the best growth for kepok banana seedlings using banana corm.. This research was conducted in Sijunjung Regency. Efforts to provide banana seeds are carried out by utilizing banana corm which will produce 3 and 4 tillers per tuber and the production time is much faster than seeds from tillers. To get the best banana corm growth, a study was conducted using a mixed planting medium of soil and cow manure with five comparisons. The treatments were: A. Soil with cow manure 1:1 ratio, B. Soil with cow manure 2:1 ratio, C. Soil with cow manure 3:1 ratio, D. Soil with cow manure 4:1 ratio, E .Soil only. The treatment was repeated 5 times. The design used was a randomized block design and continued with DNMRT (Duncan New Multiple Range Test). Parameters observed were when shoots appeared, percentage of growth, shoot height, stem diameter, number of leaves, leaf length, root length and number of roots. The results showed that the best planting medium for planting banana kepok from corm was a medium consisting of soil and cow manure with a ratio of 1:1. This treatment gives the best results for all parameters.

Abstract

Weed Eleusine indica L. was reported to have been difficult to control using glyphosate in Oil palm plantation during the time. Sulfentrazone was used as an alternative herbicide for the management of resistant weeds. The aim of this study was to determine the effects of two active ingredients Glyphosate and Sulfentrazone on weed Eleusine indica L. resistant to herbicide. The study was conducted using Completely Randomly Designed (CRD) with 14 treatments and 3 replications. 14 treatments consisted of single herbicide Glyphosate, which was applied at field rate 2 l/ha, Sulfentrazone was sprayed at the numerous dose of 500, 750, 1000, and 1250 ml/ha, and the mixture of Glyphosate and sulfentrazone at the dose of 500 ml/ha + 2 l/ha and 750 ml/ha + 2 l/ha, respectively. The research was conducted at the Greenhouse of the Faculty of Agriculture, Andalas University, Padang, from August to December, 2021. The results showed that there were significantly effect when used in combination of herbicides Glyphosate and Sulfentrazone, showed 100% of mortality weed after 3 week application. For a single active ingredient, Glyphosate controlled eficiently weed at the 4-leaf stage, Sulfentrazone had same impact on managing weed on the 4 and 6-leaf stage, both caused 100% weed dead. However, weed Eleusine indica L. was treated with Glyphosate still survived on 6 and 8 leaves weeds. Similar to Glyphosate, Sulfentrazone could not completely control resistant weeds at the 8-leaf stage. Classification of resistant weed Eleusine indica L. are herbicide-developing resistance 14%, herbicide-resistant 22%, and herbicide-susceptible 64%.

Abstract

Areca nut is one of Indonesia’s leading export commodities that must adhere to certain phytosanitary requirements, including being pest-free. It is infested by several types of insect pests during the storage process. Therefore, this study aims to determine the diversity of warehouse pests that infest areca nuts. It was conducted using a survey method at three warehouses of large collectors and exporters of areca nut in the Padang city and the Padang Pariaman regency. The purposive sampling method was adopted to collect samples from three traders' warehouses. Furthermore, the nut was taken diagonally in a pile, namely the corner and center of 1 kg each, and repeated 4 times. The identification key was used to identify 15 insect types from 10 families and 3 orders. The Cryptolestes pusillus, C. ferugineus, and Carpophilus sp. were found with the highest number of individuals in each warehouse. The diversity index of the three warehouses is 1.78, 2.14, and 1.90 indicating a moderate level. Additionally, the similarity index between warehouses shows a high and very high level of species similarity.

Abstract

One of the efforts that can be done is to increase the national corn productivity by developing prolific composite corn varieties. This is done because prolific corn is a type of corn with a tendency to produce two or more cobs, so that it can increase the value of corn production. The purpose of this study was to obtain prolific corn candidates (two cobs) with high yield and uniformity. This research was conducted using the mass selection method. Mass selection is done by selecting plants that have the desired character, namely prolific corn (cob two). The observed variables were the diversity in the F4 population, the percentage of prolific maize, and the comparison of the yield components of prolific maize with non-prolific maize. This study succeeded in obtaining 50% prolific corn on the cob and has wide diversity criteria. Of the 561 prolific corn plants, there are 91 corn plants that are classified as productive prolific. Prolific maize has a higher yield component than non-Prolific maize. Seed weight with cobs on productive prolific corn reached 318 g and seed weight reached 268 g.

Abstract

This study aims to determine the role of biochar and mycorrhizal fungi in increasing soil fertility Inceptisols as suboptimal soil, which are poor in nutrients, low in carbon, and phosphorus, are suitable for planting of purple pulut corn (Zea mays ceratina Kulesh). This study used a randomized block design (RAK) with a factorial pattern of 3 replications, namely the dose of biochar (B) 0 t/h, 2 t/h, 4 t/h, and mycorrhizae (M) with a dose of 0 t/h, 0.2 t/h, 0.4 t/h. The data obtained were further tested with Duncan's multiple range test at a level of 5%. The application of biochar and mycorrhizae affected the number of leaves, days of flowering for males and females, and rows of This study aims to determine the role of rice husk biochar and mycorrhizal fungi in increasing soil fertility. Inceptisols, which are poor in nutrients, low in carbon, and phosphorus, are suitable for planting. There is an interaction in the administration of biochar 2 t/h + mycorrhiza 0.2 t/h on rows per row of purple pulut corn cobs. The application of biochar and mycorrhizae can overcome land infertility and provide the nutrients suitable for crops for supporting sustainable agriculture.

Abstract

Citronella grass (Cymbopogon nardus L) is one of the essential oil-producing plants from the Gramineae group. This research was conducted in the Greenhouse of the Faculty of Agriculture, Andalas University, Padang from August 2017 until January 2018. This study aimed to determine the effect of Acaulospora sp and different water treatments on the growth of citronella grass in ultisol. A completely randomized design with two factors was used. The first factor was treatment with or without Acaulospora sp. The second factor was the water supply which consisted of three treatments (saturated, three quarters saturated and half saturated soil). Every treatment was repeated three times. Data were analyzed by analysis of variance using the F-test at the 5% level. Significant differences were further tested using Duncan’s New Multiple Range Test also at the 5% level. Treatment with Acaulospora sp and 75% saturated soil gave the best number of leaves and canopy to root ratio. Treatment with Acaulospora sp showed the best results for the number of tillers, stem diameter, root dry weight, and dry weight of the citronella plants. Acaulospora spp promote the growth of citronella grass.
