Sebanyak 8 hibrida dan 2 varietas pembanding ditanam pada rancangan tersarang tiga ulangan. Genotipe tersarang pada taraf pupuk N. Taraf pupuk N meliputi 100 kg N ha-1 dan 200 kg N ha-1. Indeks toleransi meliputi Tolerance (TOL), Mean Productivity (MP), Geometric Mean Productivity (GMP), Harmonic Mean (HM), Stress Tolerant Index (STI), Relative Tolerant Index (RTI), Stress Susceptibility Index (SSI), Yield Index (YI), Stress Relative Index (SI), Yield Stability Index (YSI), Stress Susceptibility Percentage Index (SSPI). Hasil penelitian menunjukkan bahwa indeks toleransi menunjukkan bahwa MP, GMP, HM dan STI merupakan yang paling sesuai untuk menyeleksi hibrida toleran N rendah.

The study purposed to determine the effect of different pH conditions both without and with Al on the viability and vigor of different varieties of soybean seeds. This research was a factorial experiment in a Completely Randomized Block Design (RCBD). The first factor was seven soybean varieties, namely Anjasmoro, Grobogan, Detap 1, Derap 1, Deja 1, Dega 1, and Dena 1. The second factor was three pH levels in Al solution, namely without Al pH 7, solution with AlCl3.6H2O pH 6—7, and solution with AlCl3.6H2O pH 4.5. There were 21 treatments with three replications. The differences between treatments were analyzed using the Least Significant Difference (LSD) at a 5%. The results showed that media without Al had the best viability and vigor followed by Al pH 6—7 media and Al pH 4.5 media. Varieties with the best vigor and viability were obtained in the Dega 1 variety as reflected in the variables of radicle emergence, germination, vigor index, hypocotil, and root dry weight, and root length.

In terms of control, many farmers in Indonesia are still using synthetic insecticides that are not environmentally friendly, so intoxicating yam (Dioscorea hispida Dennts) and tropical whiteweed (Ageratum conyzoides L.) are used as botanical insecticide that are environmentally friendly. The objective of this research is to determine the effect of botanical insecticide that made of intoxicating yam extract, tropical whiteweed extract, and mixed extract of intoxicating yam and tropical whiteweed on the mortality of cocoa pod sucking pests. This research was carried out from November 2020 to February 2021, at the Plant Laboratory II Estate Crop Department, Politeknik Negeri Lampung. The research used a Randomized Block Design (RBD) consisting of four treatments, namely: P0 (control), P1 (intoxicating yam extract), P2 (tropical whiteweed extract), and P3 (combination of both extracts), which were repeated six times. The highest mortality of cocoa pod sucking pests was found in treatment P1 (72.73%). The mortality of cocoa pod sucking pest was caused by extract of intoxicating yam which contains the active ingredients of saponins, alkaloids, flavonoids, and cyanide which enter the digestive system of the cocoa pod sucking pest as stomach poisons, resulting in the death of the cocoa pod sucking pest. Based on the results of the research, it was concluded that intoxicating yam extract is the most potential as botanical insectiside for cocoa pod sucking pest.","PeriodicalId":34207,"journal":{"name":"Jurnal Agro Industri Perkebunan","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47165156","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}
