Therefore, drought-tolerant rice varieties are needed, but until now, the number is very limited. It is crucial to produce drought-tolerant rice because Indonesia has a relatively sizeable dry land of 148 million ha. This study aimed to obtain a genotype of upland rice that is tolerant to drought with high productivity and can be developed in the dry land.   This research was then continued with drought tolerance testing by giving water below field capacity in a greenhouse. This study was in a factorial form using a Split Plot Design, with the main plot of drought stress treatment consisting of tree levels, namely water availability field capacity water,  field capacity water, and field capacity water. The sub-plots were four genotypes of upland rice from Deli Serdang North Sumatra consisting of Sialus, Arias, Silayur, Sirabut and one drought-tolerant variety for comparison is Inpago11. The observed variables included plant height, chlorophyll content, number of tillers, number of productive tillers, age of flowering, harvest period, grain weight per clump, and weight of 100 grains. The heaviest drought stress (FCW) caused a significant decrease in plant height, number of tillers per clump, number of productive tillers, and grain weight per clump and extended the flowering and harvesting ages. Based on the tolerance index criteria, it was found that the Silayur genotype was more tolerant to drought stress than the other upland rice genotypes.","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130699274","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 other objective is to know the effect of the type of compost on the growth of oil palm seedlings in pre nursery with coastal sandy soil. Lastly, the study examines the right dose of compost that provides the best growth of oil palm seedlings in pre nursery with coastal sandy soil. The experimental design was set in a factorial completely randomized design (CRD) consisting of two factors from April to June 2020  at the Tridharma Research Station  Faculty of Agriculture, INSTIPER. The first factor is the type of compost which consists of 2 levels, Lamtoro compost, and vermicompost. The second factor is the dose of compost consisting of 4 levels: control (without compost), 50 gr compost/polybag, 75 gr compost/polybag, and 100 gr compost/polybag. The research data were analyzed using analysis of variance (α =0,05), and if there was a significant effect, it was continued with the Duncan multiple range test ( α = 0,05). Parameters observed included seedling height, total leaf, leaf width, stem diameter, shoot dry weight, root dry weight, root length, and total roots. The results showed that no combination of types and doses of compost significantly affected the growth of oil palm seedlings in pre-nursery. Using vermicompost can significantly increase oil palm seedlings' leaf area and root dry weight. Using compost at a dose of 50 g/polybag increased seedling height, stem diameter, and root dry weight in pre-nursery of oil palm seedlings.","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116686676","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 research was carried out at the Tamanbogo Lampung Experimental Garden in the 2021 planting season (MT) using an augmented design with five replications of comparison varieties: Inpago 8. Inpago 12, Inpago 13. Situbagendit, and Situpatenggang. As many as 247 promising breeding rice lines were used as materials in this experiment with their respective advantages. Each line was planted with a 0.9 m x 5 m plot size with a spacing of 30 cm x 15 cm. Fertilizer used is 300 kg/ha NPK + 100 kg/ha Urea. Weeding is done twice, precisely at the time before the next fertilization I and II. The observations include 50% flowering age, harvest age, plant height, tiller quantity, dry-milled grain yield, and resistance to biotic and abiotic stresses. The analysis of variance showed that the genotype significantly affected plant height and productive tiller quantities. High heritability and genetic advances in plant height characters indicate that this character is a selection criterion so that selection can be made to increase these characters. The comparison varieties significantly affected the character of plant height and productive tiller quantities. From this activity, 37 breeding lines were obtained with higher yields than the comparison varieties.","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131679708","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}

SQI is a soil variable with the following characteristics: 1) well correlated with ecosystem processes; 2) integration of physical, chemical, and biological soil properties; 3) good sensitivity to human-induced soil changes; 4) simple measurement and interpretation; and 5) Reproducibility Soil quality index (SQI) is a diagnostic procedure to evaluate soil function and overall health. This research was carried out on a unit of land in a dry area in Aceh Besar District with a study area of 239,439.63 ha. Analysis of biomass samples and soil samples was carried out at the Laboratory of Soil and Plant Sciences and Soil Physics Laboratory, Faculty of Agriculture, University of Syiah Kuala. The tools used in this study include a set of computers with the Microsoft Windows 10 operating system that are equipped with several software for analysis, writing instruments, and other supporting tools. The main materials used in this study were soil samples, tree diameter measurement data, and land use maps, including geology, climate, slope class, soil, and topography. The results of the correlation analysis test showed a value of 0.6358. This shows that the relationship between soil C potential and soil quality index is a strong correlation. The distribution of carbon in the soil also has a close relationship with the soil quality index and is an effort to maintain carbon stocks in the soil. C - organic content is a very important parameter in compiling soil quality index criteria. Soil quality can be affected by many factors, such as parent material, environmental factors, land use type, and human activities. The percentage of soil organic C is an indicator of the percentage of soil organic matter (BOT), and BOT is able to improve soil structure and aggregates. Soil organic carbon (SOC) concentration is closely related to soil quality and vegetation productivity. This relationship occurs because of the many contributions of soil carbon to soil properties such as the improvement of soil structure and water retention, provision of cation exchange capacity, and supply of plant nutrients through mineralization. This effect is especially important in small-scale tropical farming systems where the use of external inputs is often limited, and SOC concentrations have been positively correlated with yield levels for a variety of tropical soils.","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126071966","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}

In Cangkringan, Sleman, Yogyakarta, this study aims to discover diseases. Compute the percentage of disease attacks, and determine the causes of diseases that affect coffee plants. The Central Laboratory of the Yogyakarta Institute campus is located in the Sleman Regency's Maguwoharjo District. The sample took place in the hamlets of Kopeng, Petung, and Gondang Pusung in the Cangkringan District, D.I. Yogyakarta. The research was done between March and September of 2021. The survey, collection, and identification of fungi that cause coffee plant illnesses in the field and laboratory were the research techniques used. Additionally, farmers who work on coffee plantations were interviewed. Descriptive analysis was done on observational data related to illness symptoms. According to data on environmental conditions in the three coffee plantations, Petung Hamlet had the highest elevation (875.7 masl), Kopeng Hamlet and Gondang Pusung Hamlet had the highest air temperature (27.9 °C), Gondang Pusung Hamlet had the highest air humidity (75%), Kopeng Hamlet had the highest irradiation intensity (1947 Lux), and the three hamlets' soil pH ranged from 5.5-7. A quantitative analysis of the illness attack rate was performed. On the macro- and micro-morphological characteristics of mushrooms, qualitative analysis was conducted. The findings revealed that fungi were to blame for four different types of coffee plant illnesses. These illnesses include sooty mildew, leaf spot, scurvy, and leaf rust (all caused by the fungus H. vastatrix) (Capnodium sp.).
