Johar (Cassia seamea) is a medicinal plant with a cassiarin A compound to combat malaria and has a low Cassiarin A is an active compound in Johar (Cassia seamea) medicinal plant capable of combating malaria, despite showing a low seed production rate due to dormancy. This inactivity is severed using gibberellic acid (GA3) treatments. This study aims to determine the effects of concentration and soaking period of GA3 on seed germination and growth of Johar seedlings. A completely randomized design (CRD), consisting of 2 treatments was applied as the research method. The first treatment employed GA3 concentrations of 0, 45, 90 and 135 ppm, while the second was based on the soaking interval at 6, 12, 18 and 24 hours. The results showed the capacity of GA3 able to shatter the seed dormancy with percentage germination of 43.03% and a concentration of 50.28 ppm. Therefore, the interaction of the two treatments significantly influenced the growth of Johar seedlings. Consequently, the concentration of GA3 at 79.89 ppm increased the root length to 52.19 cm, while 84.68 ppm produced a total of 20.91 roots, after a 6 hour soaking. In addition, the 96.67 ppm expanded the stem diameter by 0.93 cm.

Soybean is including a major protein source with a relatively higher consumption rate. Similarly, various efforts have been adopted towards boosting production, including selecting high-yield species and soil fertility improvement using fertilizers. This research aims to increase soybean production by employing the appropriate variety and phosphate fertilizers to improve soil fertility. This experiment was conducted in Takalar, South Sulawesi, between April-July 2019. The split-plot design method was applied with three replications. Consequently, the main plot encompasses the treatment of three varieties, termed Argomulyo, Anjasmoro and Gema, while the subplots relate to phosphate fertilization, comprising three levels, including fertilization with a dose of SP-36 at 50, 100 and 150 kg.ha-1. The results showed that the modifications in variety and phosphorus fertilization significantly influenced soybean production, as Argomulyo obtained the maximum rate of 2.77 t.ha-1, followed by Anjasmoro at 2.45 t.ha-1. Furthermore, phosphate fertilization with a dose of SP-36 at 100-150 kg.ha-1 demonstrated the optimal soybean production as indicated by the maximum productive nodes and pods. Therefore, no interaction was observed between the various species and phosphate fertilization.

Shallot production in Central Sulawesi recorded a decline from 8.651-8.362 tons, between 2017-2018. However, the use of an accurate composition of the planting medium serves as a possible alternative to boost the yield. Also, the introduction of organic matter tends to increase the nutrient content, influence the aeration, and subsequently leads to drainage. This study is aimed at determining the effect of plant media composition on shallot growth and yield. A randomized block design comprising 4 treatments, termed soil composition, husk charcoal, and goat manure. Each treatment was repeated at 5 times to achieve 20 experimental units. The results showed that the plant media composition indicated a significant effect on the parameters of plant height at age 4 and 6 Weeks After Plantings (WAP), quantities of leaves aged 4 WAP, tillers aged 6 WAP as well as tubers per clump. Similar impacts were also reported on plant height at 2 WAP, the number of leaves aged 2 and 6 WAP, fresh tuber weight, tuber diameter, accumulated weight loss, root length, and available moisture content. Furthermore, the addition of husk charcoal and manure at a volume ratio of soil: husk charcoal: manures = 2:1:1, tends to increase the quantities of leaves, tillers, tubers per clump, as well as plant height, fresh tuber weight, and shallot bulb diameter.

Nutrient availability is very significant in supporting plant growth. The low content of organic fertilizers and existing minerals appear as the primary limiting factors for soybean cultivation on acid soils. Therefore, the purpose of this research is to determine the effect of organic fertilizers and Plant Growth Promoting Rhizobacteria (PGPR) on plant growth and yield. A completely randomized block design (CRBD) factorial with three replications was employed, where the first variable involved the chicken and cow composts as well as Tithonia green fertilizer. Meanwhile, the second referred to PGPR at 0, 5, 10 and 15 ml.L-1. The results showed no interaction between the application of organic fertilizers and PGPR on soybean growth as well as the yield. Furthermore, the cow manure treatment of 10 t.ha-1 reportedly increased the total dry weight and sample growth rate by 0.44 and 0.86%, respectively, compared to the chicken manure at similar composition. Also, 10 ml.L-1 of PGPR was known to improve the pod quantity per plant and harvest index by 0.58 and 2.66% harvest index, correspondingly, than without PGPR.

Sloping topography, clay textures and improper fertilizer application create a high risk of surface runoff and nutrient loss. Phosphorus occurs as an important nutrient in coffee beans. The objective of this research is to analyze the effects of biopore infiltration hole with compost (BIHC) on the total and available phosphorus in robusta coffee in Bangelan plantation, Malang. A complete randomized block design with 4 replications was applied and the treatments consisted of control and BIHC. The BIHC process involved biopore hole depth of 30 and 60 cm for the goat manure and coffee pulp compost, respectively. Several parameters were also observed, including pH, total and available phosphorus as well as soil organic carbon (SOC) between 0-20, 20-40 and 40-60 cm in soil depth. Subsequently, the analysis of variance (ANOVA) and Duncan's Multiple Range Test (DMRT) were used to comprehend the data. The results showed the ability of BIHC to significantly increase the pH, SOC and total-P, compared to the control with less available-P. These total-P improvements up to 103.27, 108.73 and 132.09% were reported at soil depths between 0-20, 20-40 and 40-60 cm, respectively, while available-P were possibly enhanced up to 77.59, 28.27 and 151.99% at corresponding depth ranges.

The aimed of this study to study the effect of herbicide paraquat dichloride 276 g / L in suppressing weed growth in hybrid corn plantations with NTS. The study was conducted in April-September 2017 on land located in Tenjolayar Village, Cigasong District, Majalengka with an altitude at 193 above the sea level. The experiments used Randomized Complately Block Design (RCBD) with 6 treatments and 4 replications so there’re 24 experimental plots. The treatment were 1) 0.75 L / ha + TOT, 2) 1 L / ha + TOT, 3) 1.25 L / ha + TOT, 4) 1.5 L / ha + TOT, 5) Weeding manual + TOT, and 6) Control (OTS). Differences between treatments were tested using the F test, while to test the average value of treatment used Duncan's Multiple Distance Test 5%. Herbicide paraquat dichloride 276 g / L affects could suppress weed growth done on 1 week after application and 5 weeks after application. The optimum dose of paraquat dichlorthereide 276 g / L in weed control in hybrid corn plantations was 1.5 L / ha at 1 week after application and 5 weeks after application.","PeriodicalId":107826,"journal":{"name":"Agrotechnology Research Journal","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130691102","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}

Fertilization is any effort that aims to increase the availability of nutrients needed by plants, and increase crop production. The study aimed to obtain fertilizer types, fertilizer dosages and combinations of types and dosages of fertilizers suitable for growth and yield of Crystal Guava plants. The study was conducted on October 2018 to Mei 2019 on farmer’s land, Banjarsari Kulon Village, Sumbang District, Banyumas Regency and Agronomy and Horticulture Laboratory of the Faculty of Agriculture, Jenderal Sudirman University. The experimental design used was a Randomized Completely Block Design (RCBD) with 2 factors and 3 replications. The first factor was the type of fertilizer, namely NPK, SP-36 and MKP fertilizers. The second factor was fertilizer dosage, namely 20 g / plant, 30 g / plant, 40 g / plant and 50 g / plant. Observed data were done by Analysis of Variance and if it significantly affected then DMRT (Duncan’s Multiple Range Test) was carried out at the level of 5%. The results showed that the most effective type of NPK fertilizer and dosage of 20 g / plant. The combination of NPK fertilizer with a dose of 20 g / plant was the most effective treatment for increasing the growth and yields of the Crystal Guava plant.
施肥是任何旨在增加植物所需养分的可用性和增加作物产量的努力。本研究旨在获得适合水晶番石榴生长和产量的肥料种类、肥料用量以及肥料种类和用量的组合。该研究于2018年10月至2019年9月在Banyumas县Sumbang区Banjarsari Kulon村的农民土地和Jenderal Sudirman大学农学院农学和园艺实验室进行。采用随机完全区组设计(RCBD)， 2因素，3个重复。第一个因素是肥料类型，即NPK、SP-36和MKP肥料。第二个因素是肥料用量，分别为20 g /株、30 g /株、40 g /株和50 g /株。观察到的数据通过方差分析完成，如果它显著影响，则在5%的水平上进行DMRT(邓肯多元范围检验)。结果表明，氮磷钾肥类型和用量为20 g /株最有效。氮磷钾配施20 g /株是提高水晶番石榴植株生长和产量的最有效处理。
