Consumption of herbal medicines by Indonesian people is increasing because of the price and ease of obtaining them. One of the main ingredients of herbal medicine is mint leaves because they contain tannin and flavonoid secondary metabolites. However, the generative mint plant is very slow and needs vegetative cuttings propagation. This study aims to examine the effect of auxin-type growth regulators and the composition of the growing media on the growth and yield of mint plant cuttings. This study used a complete randomized block design with two factors. The first factor was the auxin growth regulator with four levels: without growth regulator, IBA 500 ppm, IAA 500 ppm, NAA 500 ppm. The second factor was the composition of the planting medium with three levels, namely soil, husk charcoal, and goat manure 3:3:1; 3:2:2, and 3:1:3. Three repetitions were carried out. Auxin affects the number and area of leaves. Applying 500 ppm NAA encouraged the highest leaf growth, with the number of leaves at 163.38. Growth regulator NAA 500 ppm increased the number of leaves and leaf area of mint plants, i.e., by 0.01% and 1.16% compared to the control. The growing media composition affected the crown fresh weight, root biomass, and crown root ratio. The media composition of 3:3:1 produced a crown fresh weight of 41.07 g, and the media composition 3:3:3 produced the highest biomass of 5.97 g. The media composition 3:1:3 showed the highest root crown ratio, 2.69%. Auxin and the composition of the growing media synergistically promote the growth and yield of mint cuttings.

Mentik Susu is a popular rice germplasm in Indonesia. Due to field constraints in Mentik Susu rice cultivation, farmers switched to better varieties with higher yields. Farmers switch to superior types with high yields due to high plant posture, long harvest life, and low yields. Rice plants usually have a protein content of 4-5% per gram while without given radiation. It will be expected that after receiving gamma rays, the protein content in mutant plants will increase up to 7-8% per gram. The aim of this research was to evaluate the productivity and protein content of rice grain of 35 mutant strains of rices that could be developed into new varieties. The research took place at the Tegalgondo Rice Seed Garden Agricultural Land between June to October 2020. This research used Randomized Complete Block Design method with a single factor. Each treatment was repeated three times. The data obtained was analyzed with analysis of variance and followed with Duncan’s Multiple Range Test at a 5% level if any significant influences. The results of this research showed productivity of 35 Mentik Susu rice lines ranged from 4.28 to 6.69 ha-1, with either a high protein content ranging from 5-8% per gram and intermediate high yield potential strains G63T11-B6-T27(1), G15T5-14-B5-T60, G15T5-14-B5-T46, G11T22-19-B1-T48, G15T5-14-B3-T36, M-MS2-G15T3-2-5 -T27, M-MS2-G18T7-4-12-T13, M-MS2-G18T7-4-9-T12. These strains might be cultivated as potential candidates for new high-yielding varieties, which would then be evaluated for higher yields or multilocation tests before becoming published as new varieties.

The bean fly (Ophiomyia phaseoli) is a major pest of soybean in Indonesia which causes the plants to die early in growth. Most farmers use insecticide synthetics to control this pest. Therefore the alternative control of bean flies is needed to reduce reliance on farmer's usage of chemical pesticides. One of the alternative control is with application of husk ash that has a high silica content. This study examined husk ash to know the effect of husk ash to population and proportion of bean flies attacks. This research conducted in Pengkok Village, Kedawung, Sragen from June - September 2019. The method used was field experiment with a Randomized Completely Block Design (RCBD) with one factor, namely the dose of husk ash five levels (0 tons ha-1, 1.25 tons ha-1, 2.5 tons ha-1, 3.75 tons ha-1, and 5 tons ha-1) and five replications. The results showed that the application of husk ash not affected significantly on the adults of the bean fly population, but affected significantly the percentage of attacks only in the cotyledons. The application of rice husk ash can reduce the percentage of attack on the cotyledons by 2.11-3.04% than without husk ash application. The number of plant deaths apparently followed the populations of bean flies. Furthermore, the height of soybean with application looked taller than without application.

Biochar is a carbon-rich solid material derived from the pyrolysis of agricultural residue biomass, which takes longer to decompose than the raw material biomass. Biochar has been observed to have agronomic benefits. Because of its persistence in the soil, biochar has the potential to extend its agronomic benefits. The purpose of this study was to obtain evidence that biochar has a longer effect so that its residual effect can increase the growth and yield of soybean. A series of pot experiments which included 4 consecutive plantings were carried out. The treatments consisting of: control; rice husk biochar (RHB) 20 ton.ha-1; RHB 40 ton.ha-1; RHB 50 ton.ha-1; RHB 60 ton.ha-1; RHB 10 ton.ha-1 + chicken manure (CM) 10 ton.ha-1; RBH 20 ton.ha-1 + CM 20 ton.ha-1; RHB 30 ton.ha-1 + CM 30 ton.ha-1. The treatments were applied to the first planting of the series experiment (September-December 2018). To determine the residual effect of the treatments, the second experiment was carried out in February-June 2019 with planting aerobic rice plants, third experiment in March-June 2020 with soybeans plant, and fourth experiment in July-October 2020 with soybean plants. The results showed that the effect of residual rice husk biochar did not significantly increase growth and soybean yields in the 3rd and 4th planting.

Wheat is the largest cereal food in the world's staple food supply. The expansion of the wheat crop needs to be done through extensification efforts in the lowlands to increase domestic production. The main obstacles faced in the lowlands are the high air temperature and the intensity of sunlight. The research objective was to provide adaptive wheat mutant in the lowlands, especially in North Sumatra. The seeds of 3 varieties of wheat: Dewata, Basribey and G-21 were treated with gamma irradiation with a dose 100, 200, 300, 400, 500, and 600 Gy. Each treatment was repeated three times. The highest percentage of germination and vigor index due to the combination of treatment of wheat varieties with gamma rays was the combination of Dewata and 200 Gy which was significantly different from Basribey and G-21. Gamma irradiation treatment of 100 Gy on the three mutant wheat varieties showed differences in plant height, namely the G-21 variety, followed by Dewata and Basribey. The number of productive tillers showed significant variation between the gamma ray treatments for each mutant wheat genotype and the most productive tillers were at a gamma ray dose of 100 Gy for all wheat genotypes. The 100 Gy gamma ray treatment caused the number of seeds of the Dewata variety to be much higher than that of Basribey and G-21. The mutants obtained with the desired characters are the basic materials in assembling new superior varieties of wheat that are adaptive in the lowlands.

The mutants obtained with the desired characters are the basic materials in assembling new superior varieties of wheat that are adaptive in the lowlands.","PeriodicalId":107826,"journal":{"name":"Agrotechnology Research Journal","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139367638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The demand for butternut squash which continues to increase every year makes farmers try to increase their production, one of which is by applying biological and organic fertilizers. This study aims to determine the response of growth and production of butternut squash to the application of mycorrhiza and quail manure. This study used a randomized block design with 2 factors and 3 replications. The first factor was the application of mycorrhiza which consisted of 3 levels, namely: 0, 2.5, and 5 g/plant, while the second factor was quail manure which consisted of 4 levels, namely: 0, 1, 2 and 3 kg/plot. The results showed that the application of mycorrhizae had a significant effect on fruit length and fruit weight. The application of quail manure had a significant effect on increasing fruit weight. The interaction of mycorrhizae and quail manure did not significantly affect all observed parameters. Although it had no significant effect, the application of mycorrhiza and quail fertilizer was proven to increase the growth and production of butternut squash compared to the control (without the application of mycorrhiza and quail manure). The combination of mycorrhizal 2.5 g/plant and quail manure 1 kg/plot could increase butternut squash production.

Soybean are basic need and the main source of vegetable protein for most of the Indonesian population. Organic matter and Rhizobium are improvement efforts to optimize soybean growth between durian plants. The purpose of the research was to determine the use of Rhizobium and organic fertilizers on the growth and yield of soybeans between durian plants in LubukKelik village, Bangka. The experiment used split plot and RAL design. The main plot was Rhizobium applications consist of without Rhizobium (P0) and Rhizobium application (P1). The sub plot was the use of organic fertilizers, which consists of chicken manure (K1) and empty oil palm fruit bunches compost (K2). The results showed that the types of organic fertilizer application not significantly affected soybeans growth dan yield in between durian plants. Empty fruit bunches compost provided the best growth on soybean plants. The best yield of soybean in between durian plants are shown by empty fruit bunches treatment. Rhizobium application significantly affected growth parameters of soybean and effective root nodules. Soybean growth parameters with Rhizobium application was better than without Rhizobium application. Interaction between organic fertilizers and Rhizobium significantly not affected soybeans growth dan yield. Combination of empty oil palm fruit bunches compost with Rhizobium is treatments that provide the best growth of soybean.

The activity of changing land functions from rubber and cocoa plantations to sugar cane plantations and using conventional technical land processing systems can affect the population of ground surface insects such as ground beetles. Ground beetles are one of the important insects that act as predators and are sensitive to environmental conditions. The aim of this research is to determine the diversity and number of ground beetle populations in the sugar cane fields at PTPN XII Kalitelepak Plantation. This research used a pitfall trap consisting of 5 plots and 9 traps were installed in each plot with a distance of 10 m between traps. Samples were taken 15 times every 3 days. The research results showed that the ground beetles caught were from the Carabidae family which consists of the species Chlaenius bimaculatus, Chlaienius virgulifer, Chlaenius pictus, Chlaenius cambodiensis, Pheropsophus occipitalis, Pterostichus melanarius, Harpalus affinis, Nebria brevicollis, Planetes puncticeps with a total of 143 individuals. The highest important value index is the species Chlaenius bimaculatus at 104.96. The diversity of ground beetles in sugar cane plants at PTPN XII Kalitelepak Plantation is in the low category because it is less than (<) 1, namely with a value of 0.79. Human activities such as taking grass and changing land use can affect diversity, so conservation needs to be carried out to increase the diversity of ground beetles.
