Abstract

As a genetic resource, local rice can provide insight into the inheritance of favorable traits. Local rice varieties have naturally been tested for resistance to pests and diseases, high yields, good rice quality (including class 1 quality), and a taste that people like, but also have some disadvantages, such as long life and high plant height that easily collapses. For this reason, the characteristics of local rice varieties that have these advantages are improved using the gamma-ray induced mutation technique. Before planting in the field, it is necessary to test the vigor and viability of local rice genotypes (Oryza sativa L.) Padang Pariaman seeds first. In this study, researchers used three different rice varieties, namely: "Madang Pulau", "Putiah Papanai", and "Banang Kuniang" and gamma irradiation, with radiation doses of 0, 100, 200, 300, 400, 500, and 600 Gy. Based on the results of the study, the local rice seed varieties of Padang Pariaman Regency and the dose of gamma irradiation had a significant effect on maximum germination, while germination speed, germination capacity, vigor index, and growth uniformity were significantly affected by the dose of gamma irradiation. Gamma irradiation with doses of 400-600 Gy resulted in a more significant decrease in seed vigor and viability compared to irradiation with doses of 100-300 Gy.

Abstract

Maize is a second important food crop, its yield is the raw material for the feed industry. As for other crops, maize can not avoid weed association and interference. Weed may cause farmers’ economic loss. An experiment to determine the efficacy of thiencarbazone methyl+isoxaflutole herbicide and its effects to control weeds and maize yield was conducted from October 2022 to February 2023 at Ultisol of Universitas Andalas, Limau Manis, Padang. The experimental units were laid out according to a completely randomized block design (CRBD) with 10 treatments and three replications. The treatment was different types of weed control namely: no weeding, various doses of herbicide thiencarbazone-methyl 90 g L-1+isoxaflutole 225 g L-1 i.e 250 mL ha-1, 300 mL ha-1, 350 mL ha-1, and 400 mL ha-1 applied at 2 and 10 DAP, respectively, and manual weeding. Herbicide thiencarbazone-methyl 90 g L-1+isoxaflutole 225 g L-1 effectively controlled Erechtites valerianifolia, Oxalis barrelieri, and Asplenium rhizophyllum. Herbicide at 350 mL ha-1 applied dose at 2 DAP reduced weed dry weight per m-2 as much as 93% at 6 WAP. Weed control by herbicide application increased 72.20% of maize yield per ha compared to the no-weed-control treatment group without causing phytotoxicity on maize plants.ABSTRAK Tanaman jagung merupakan tanaman pangan penting kedua dan menjadi bahan baku industri pakan. Seperti tanaman lainnya, tanaman jagung juga tidak dapat terhindar dari interaksi dan asosiasi dengan gulma. Keberadaan gulma pada pertanaman jagung dapat menimbulkan kerugian ekonomis.

Abstract

Weeds are plants whose presence is unwanted by humans because of competition with cultivated plants for nutrients, sunlight, and growing space, producing allelochemicals that interfere with plant growth, reduce production and product quality, and increase farming costs. The continuous use of synthetic herbicides has adverse effects on the environment and health, so it is necessary to seek a weed control mechanism that is more efficient and environmentally friendly. One is utilizing secondary metabolites, namely sunflower plant allelochemicals, that can control weeds. This study aims to determine the response of weeds to the application of extracts of sunflower plant parts as bioherbicides. This research was conducted in three stages: raw material preparation, extraction, and application. The results obtained 17 weed species in the experimental field of Nagari Selayo Tanang Bukit Sileh from 7 families (Asteraceae, Poaceae, Lythraceae, Polygonaceae, Brassicaceae, Caryophyllaceae, and Mazaceae) and two weed classes (broadleaf weeds and grasses). The bioherbicide efficacy of sunflower extract (Helianthus annus L.) has not caused symptoms of toxicity in weeds.

Abstract

Expansion of planting areas by utilizing sub-optimal land and the use of superior varieties is one of the alternatives in increasing soybean production in Indonesia. Therefore, this study aims to analyze the growth of three soybean varieties on Ultisol land in the Experimental Garden of the Faculty of Agriculture, Andalas University. This activity was conducted from September to November of 2022. The soybean varieties used in this study were Dena 1, Devon 1, and Demas 1. This research was designed using a Randomized Group Design with 1 factor, namely the type of variety with 3 groups of replications. The observation results of each treatment were analyzed statistically. If F count is greater than F table, then continued with Tukey's Further Test at the 5% level. It was concluded that some of the observed characters of the three soybean varieties showed that there were significant differences in growth in the observation of plant height and leaf area index. While in the observation of plant growth rate and the ratio of crown: root there was no significant difference between the tested varieties.

Abstract

Rainfall variability, in terms of amount, distribution, and timing, can increase the risk of crop failure and reduce crop yields. This study aims to analyze CHIRPS (Climate Hazards Group InfraRed Precipitation with Stations) rainfall dynamics across several coastal areas of West Sumatra and to evaluate agroclimatic zones to assess the suitability of climate-adaptive cropping patterns. Monthly rainfall data for the period 1995-2024 were analyzed using the IDW interpolation method to produce rainfall distribution maps. This study also classified agroclimatic zones using Oldeman's classification to assess the suitability of cropping patterns. The analysis showed significant annual rainfall fluctuations, with high rainfall dominating the 1995-2014 period and a decline in the 2015-2024 period. Changes in monthly rainfall patterns, particularly the increase in rainfall from March to May during the 2015-2024 period, may affect planting times and irrigation management. The three regions studied (Padang Pariaman, Pariaman, and Padang) are in climate zone A1, with more than 9 consecutive wet months, allowing year-round rice cultivation. However, rainfall fluctuations require adjustments in planting timing and the selection of secondary crops that are more drought-resistant. The results of this study provide a stronger basis for agricultural planning that is more adaptive to climate change, with recommendations for adjustments to the planting calendar and irrigation management to ensure the sustainability of efficient and sustainable agricultural production.

Abstract

Gamma ray irradiation is a mutagenesis method used to obtain new genetic variations in plants, including rice. Local varieties were chosen because they have good adaptability to the local environment and can play an important role in increasing agricultural productivity. The local varieties of rice seeds from Padang Pariaman Regency used in the research were "Madang Pulau", "Putiah Papanai" and "Banang Kuniang". The irradiation doses used were 100 Gy, 200 Gy, 300 Gy, 400 Gy, 500 Gy and 600 Gy. Seeds without irradiation were also used as controls. The results showed that the germination response of local varieties of rice seeds to gamma ray irradiation varied depending on the dose given. In terms of germination percentage, the irradiation dose of 100 Gy showed a significant increase compared to the control in the white Papanai variety. However, irradiation doses of 200 Gy and 300 Gy caused a significant reduction in germination percentage compared with the control. Apart from that, observations were also made on other parameters such as seedling height and root length. The results showed that at irradiation doses of 100 Gy, 200 Gy and 300 Gy, there was a significant reduction in these parameters. Based on these findings, it can be concluded that the use of gamma rays as an irradiation method can influence the germination response of local varieties of rice seeds in Padang Pariaman Regency differently depending on the dose and the variety used.

Abstract

One of the factors causing the low productivity of rice in West Sumatra Province is quality seeds, which are still very low. Also, many rice varieties currently used have a low resistance to pests and diseases, particularly the leafhoppers, which currently attack rice in West Sumatra. The National Nuclear Energy Agency (BATAN) is one of the institutions that produce new rice varieties through mutation technology, one of the varieties produced in the Kahayan variety. Kahayan varieties have several advantages over the previous varieties, namely early age, high productivity, and resistance to certain pests and plant diseases. This activity aims to disseminate the breeding of Kahayan rice seeds to breeding farmer groups so that they can fulfill their needs for rice seeds independently. The activity was carried out at the Air Sarasah Farmer Group in Nagari Sungai Batang, Tanjung Raya District, Agam Regency, from November 2019 to March 2020. The activity consisted of disseminating breeding activities, implementing Kahayan rice breeding, and assisting Kahayan rice varieties' breeding. From this activity, farmer groups have been able to better breed rice, according to the operational standards for seed breeding set by the Ministry of Agriculture of the Republic of Indonesia. Also, farmer groups have been able to increase their knowledge of certifying rice seeds. From the results of rice seed breeding, it was obtained that the Kahayan rice seed class Basic Seed (BD) yield was 6.1 tonnes/hectare, which exceeded the national average rice yield, namely in 2018, it was 5.2 tonnes/hectare.

Abstract

The Lubuek Kabau Sepakat farmer group is one of the farmer groups that actively cultivates strawberry plants. However, the strawberry production obtained is not optimal because of the lack of knowledge related to organic fertilizers and the source of planting material used is not clear about the origin of the variety because it is only vegetatively propagated from the previous plant. Therefore, the objectives of this service activity are 1) to educate farmer groups about ecoenzymes so that they can be used as one of the organic fertilizers to be applied to strawberry plants; 2) to provide seedlings of superior strawberry varieties so that the quantity and quality of strawberry production can increase. The activity was carried out at the Lubuk Kabau Sepakat Farmer Group, Nagari Batang Barus, Solok Regency, West Sumatra. The stages of activities carried out include: identification of partner needs and problems, preparation of programs that are in accordance with the needs / problems of partners, implementation of activities in accordance with the plans that have been made, then monitoring and evaluation. The result of this activity is that the partners' knowledge or skills related to ecoenzyme have increased so that they are able to independently produce ecoenzyme and will apply ecoenzyme to strawberry plants. A total of 150 strawberry seedlings of the premium Sweet Japanense variety have been delivered to partners so that the quantity and quality of strawberry production can increase. The results of the activity evaluation showed that 95% of the participants were very satisfied with the activities carried out by the service team. As many as 85% of participants said that this training activity was very useful in helping to reduce organic waste in the form of fruit peel residue. The relevance of themes and materials is in accordance with the needs and can be applied in everyday life.
