Merah Delima is potential to be cultivated on tidal swampland. The problems of tidal swampland are low degree of pH and low nutrient availability in the soil, thus it needs additional liming and fertilization. This study aimed to obtain the best dose of lime, also phosphorus and potassium fertilizers to increase the productivity and quality of papaya cv. Merah Delima. The study was conducted at TTP Siak, Sai Mandau district (BPTP Riau) from January 2018 to December 2019. The study used a Split Plot Design with the main plot was two doses of lime (6 and 9 t ha-1) and the subplot was combination of three doses of P2O5 fertilizer (100, 200, 300 g plant-1) and three levels of K2O fertilizer (150, 300, 450 g plant-1), with three replications. The results showed the application of lime at dose of 6 t ha-1 combined by P and  K fertilizer of 300 g plant-1 + 300 g plant-1, respectively, could increase papaya production up to 51%, whereas average production 98.00 kg plant-1, average number of fruits 95.45 plant-1, fruit weight 1,031.30 g fruit-1, TSS 11.81 °Brix, and fruit hardness of 55.08 kg cm-2. Application of lime and additional fertilizer into the tidal swampland are effective to improve its characteristics and able to increase the papaya Merah Delima production.","PeriodicalId":34207,"journal":{"name":"Jurnal Agro Industri Perkebunan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90646978","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}

Microclimate differences in the cultivation area are thought to have a significant impact on the production of secondary metabolites, such as saponins. This research aimed to observe the saponins content in the root of shallot plants cultivated in marginal agricultural land and their antimicrobial activity against bacteria (Ralstonia solanacearum) and fungus (Fusarium oxysporum). This research was observational research with a random sampling method. The samples were collected from the shallot plantation with two different cultivation conditions. Two varieties of ‘Bima' and 'Tiron' cultivated by farmers in sandy coastal land Samas, Bantul were used. The plants were harvested at 1, 1.5, and 2 months after planting, respectively. The crude saponins extract was used to test antimicrobial activity. Shallot plants cultivated in marginal coastal sandy land produced higher saponins accumulated in their roots. The saponins production increased along with the maturity of shallot plants, both cultivated in marginal coastal sandy land and regular paddy field. The saponins extracted from the roots of shallots cultivated in both marginal and regular land showed higher antimicrobial activity than antifungal activity. Saponin merupakan salah satu metabolit sekunder yang terdapat pada bawang merah (Allium cepa L.), terutama pada bagian akar. Perbedaan iklim mikro pada lahan budidaya diduga akan berpengaruh terhadap produksi metabolit sekunder termasuk saponin. Tujuan penelitian ini adalah untuk mengetahui kandungan saponin pada bagian akar tanaman bawang merah yang dibudidayakan di lahan pertanian marginal serta aktivitas antimikrobanya terhadap bakteri (Ralstonia solanacearum) dan jamur (Fusarium oxysporum). Penelitian ini merupakan penelitian observasi dengan metode pengambilan sampel secara acak. Sampel berasal dari perkebunan bawang merah dengan dua lahan budidaya yang berbeda. Digunakan dua varietas yaitu 'Bima' dan 'Tiron' yang dibudidayakan oleh petani di daerah pantai Samas,kabupaten Bantul. Bahan tanaman dipanen pada tiga waktu berbeda, yaitu 1 bulan, 1,5 bulan dan 2 bulan berturut-turut setelah tanam. Ekstrak kasar saponin digunakan untuk menguji aktivitas antimikrobanya. Tanaman bawang merah yang dibudidayakan di lahan marginal pasir pantai menghasilkan saponin yang  lebih tinggi yang terakumulasi pada akarnya. Produksi saponin semakin meningkat seiring dengan umur tanaman bawang merah, baik yang dibudidayakan di lahan marginal pasir pantai maupun di lahan sawah biasa. Saponin yang diekstraksi dari akar bawang merah yang dibudidayakan di lahan marginal dan lahan biasa menunjukkan aktivitas antimikroba yang lebih tinggi daripada aktivitas antijamurnya.","PeriodicalId":34207,"journal":{"name":"Jurnal Agro Industri Perkebunan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78182709","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}

Perlakuan priming pada benih diyakini mampu memperbaiki perkecambahan pada lingkungan yang kurang menguntungkan. Penelitian dilakukan untuk mengetahui pengaruh priming pada perkecambahan benih kedelai yang dikecambahkan dalam media masam dan mengandung aluminium. Penelitian disusun dalam Rancangan Acak Lengkap (RAL) pola faktorial. Faktor pertama adalah jenis priming : tanpa priming, H2O (air), KNO3 1%, KNO3 2%, GA3 50 ppm, GA3 100 ppm, dan PEG 6000 7,5%. Faktor kedua adalah varietas kedelai yaitu: Anjasmoro, Burangrang, dan Grobogan. Data dianalisis sidik ragamnya dan dilanjutkan dengan uji Beda Nyata Jujur (BNJ) 5% menggunakan program statistika R Studio. Hasil penelitian menunjukkan priming PEG 7,5% dan varietas Burangrang secara mandiri merupakan perlakuan terbaik untuk meningkatkan vigor benih kedelai berdasarkan variabel waktu muncul kecambah, kecepatan perkecambahan, dan panjang hipokotil.

The first factor was priming type : no priming, H2O (water), 1% KNO3, 2% KNO3, 50 ppm GA3, 100 ppm GA3, and 7.5% PEG 6000. The second factor was soybean variety : Anjasmoro, Burangrang, and Grobogan.  The data obtained were analyzed using the R Studio statistic program with a 5% HSD test. The study resulted that each PEG 7.5% priming and Burangrang  variety independently was the best in increasing soybean seed vigor based on sprout time emergence, germination speed and hypocotyl length.
