Shallots are considered a shallow-rooted crop and have been reported to have little tolerance to drought conditions. One of the efforts to increase plant tolerance to drought conditions is through the addition of Methyl Jasmonic Acid (MeJA). MeJA is involved in several physiological and biochemical procedures in plant growth and development. Application of MeJA can increase the plant tolerance to drought conditions through chlorophyll synthesis, stomatal conductivity, transpiration, net photosynthetic rate and biomass production. This research was conducted in a complete randomized block design with three replications to determine the response of shallot plants to the application of MeJA (0 µM, 25 µM, 50 µM and 100 µM) under drought conditions, which was simulated through the frequency of watering (once daily, every other day, once in three days). Soil water content calculated before the watering treatment was 24.45%, 20.34% and 18.45% for watering once daily, every other day, once in three days, respectively. The results showed that the addition of MeJA played a role in enhancing the growth and productivity of shallot plants under normal and drought conditions. Application of 50 µM of MeJA could increase the Water Use Efficiency, maintain the Relative Water Content, increase the width of stomatal aperture, and increase the leaf area and Leaf Area Index. This also led to increasing Net Assimilation Rate and Plant Growth Rate. Application of 50 µM of MeJA gave in increasing bulb productivity and reached 7.86 ton.ha-1, which was 58.2 % higher than that of in control (without MeJA application). Application of MeJA to shallot plants exhibited avoiding type of physiological tolerance.","PeriodicalId":13282,"journal":{"name":"Ilmu Pertanian (Agricultural Science)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44802576","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 experiment was conducted from July to October 2019 and from January to April 2020 at the Department of Crop Science teaching and research farm, University of Nigeria Nsukka, South Eastern Nigeria. The experiment applied a randomized complete block design with nine replications spread over three blocks. The treatments were four doses of poultry manure (0, 10, 20 and 30 t.ha-1) tried in two seasons (wet and dry season). Prior to the investigations, soil analysis of the experimental site and poultry manure nutrient content were carried out. The growth pattern and yield was higher during the wet season. Poultry manure at amount of 30 t.ha-1 gave the best growth attributes (number of leaves, leaf length, and leaf diameter) 14.22, 53.67 cm and 0.88 cm respectively while the 20 t.ha-1 had the highest plant height and bulb fresh weight, 60.86 cm and 2 kg/plant respectively. The trend was not the same as in dry season planting because 20 t.ha-1 poultry manure differs significantly from other rates of poultry manure considered. Plant height, leaf length, leaf diameter and bulb fresh weight (57.64 cm, 55.28 cm, 0.84 cm and 0.63 kg/plant respectively) were statistically significantly (p < 0.05) different at 5% probability level.

Nano-technology fertilizers are more reactive and on target with minimum use. Nanotechnology fertilizers can be utilized as slow-release fertilizers, allowing for optimum fertilizer uptake by plants. Because of the holes that can store nitrogen fertilizers, zeolite and bovine bone can be utilized as fertilizer coatings. This study was conducted at Universitas Gadjah Mada's Faculty of Agriculture. The research method used was a 2X5 factorial completely randomized design (CRD) with each treatment being repeated 3 times so that the total polybags used were 30 polybags. The first factor was the type of coating material for urea, nano zeolite, and nano bovine bone. The second factor consisted of a dose of coated urea fertilizer with five kinds of dose treatments, which were 0, 100, 200, 300, and 400kg.ha-1. ANOVA was used to analyze parameter data, followed by testing using the DMRT (Duncan's Multiple Range Test). When compared to nano bovine bone, the effectiveness of N removal with nano zeolite generated the best results as a slow-release fertilizer on N uptake. The best N fertilization dose with nano zeolite coating was 200 kg.ha-1, which increased corn plant growth by producing the highest plant height (167.17 cm) and N uptake of 1.6 g/plant. This research can be a recommendation for more effective and efficient Nitrogen fertilization for corn farmers.","PeriodicalId":13282,"journal":{"name":"Ilmu Pertanian (Agricultural Science)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41412405","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}

Therefore, further steps need to be evaluated regarding yield potential and the plant quality. This study aimed to identify fourteen promising lines of high yield and high quality and compared to commercial varieties. Fourteen tomato accessions were evaluated by three control varieties.

Data collections were analyzed using Analysis of variance (ANOVA) and continued with Duncan Multiple Range Test (DMRT) analysis with α = 5%. Path analysis showed that the selection criteria for selecting high yield of tomato lines were fruit length, pulp thickness, fruit weight /plant, and flowers number per bunch.

Organic matter needs to be applied to maintain soil fertility and balancing the dose of inorganic fertilizers.

The second factor was the use of N, P, K fertilizers in 100%, 75%, 50%, and 0% of recommended doses. The application of biochar 10 t/ha on soybeans was able to increase physiological components which include stomatal opening, stomatal density, and N, P, K uptake; growth components which include root length density, root area density, leaf area, leaf area index, net assimilation rate, crop growth rate, plant dry weight, harvest index, and yield components which include number of nodes and pods per plant, 100 seed weight, grain weight per plant and grain yield.
