Abstract

The Effect of Seaweed Liquid Fertilizer on the Growth of Oil Palm (Elaeis guineensis Jacq) in Pre Nursery. The purpose of this research is. Knowing the growth response of oil palm seedlings (Elaeis guineensis Jacq) with the application of liquid seaweed fertilizer. This research was conducted from July 2020 - September 2020, starting from sampling the height of the seeds, the number of leaves, the diameter of the stem, the wet weight of the plant, the dry weight of the plant to data processing. This study used a non-factorial randomized block design (RBD) method, namely by collecting samples of seed height, number of leaves, stem diameter, plant wet weight, plant dry weight to be analyzed by Analysis of Variance (ANOVA) with the continued test of Duncan's Multiple Range Test. (DMRT) at the 5% level. Key words: Oil palm, Pre Nursery, Seaweed

Abstract

Oil palm plants are monocotyledonous plants where there are male flowers and female flowers in one tree, the appearance of oil palm flowers is at the base of the midrib, the average time at different stages of flower development. The T-Test sex ratio test was not significantly different. The photos shown refer to the standards set by BBCH (Biologische Bundesantalt Bundessortenamt und Chemische Industrie) explaining the stages of flower and fruit development in oil palm plants. Vegetative development includes plant height, number of leaves, rachis length, petiole thickness, number of leaflets, leaflets. The research was conducted at the Indonesian Palm Oil Institute (ITSI) Medan practice garden. The time of the study starts from August 2021 to March 2022. This study aims to determine and study the stages of flowering of oil palm plants in two different varieties by observing each flowering stage that occurs in oil palm plants. The method used is descriptive with qualitative and quantitative models. The results showed that the use of different varieties gave different results on the generative and vegetative growth of oil palm plants. The photos shown refer to the BBCH (Biologische Bundensartalt Bundessortenamt und Chemische Industrie) standard of flower development stages. The results of the T-test showed that the value of sex ratio, rachis length, petiole thickness, petiole cross section (LxT), number of leaflets on one side, length and width of leaflets, leaf area gave the effect of accepting H0 (not significantly different) while the T-test -Test on plant height, number of leaf fronts and total leaf area gave the effect of rejecting H0 (significantly different).

Abstract

Abstrak Tujuan penelitian ini adalah untuk mengetahui resistensi klon IRR seri 400 terhadap penyakit gugur daun Corynespora di laboratorium. Penelitian tingkat resistensi klon karet IRR seri 400 dilakukan di laboratorium Proteksi Unit Riset Sungei Putih, Pusat Penelitian Karet. Penelitian dilaksanakan pada bulan Juli sampai Desember tahun 2020. Penelitian disusun dengan menggunakan rancangan acak lengkap non faktorial, dengan tiga ulangan. Karakter pengamatan yang diamati adalah intensitas serangan yang diamati pada hari ke 2, 4, 6, 8 hari setelah inokulasi (hsi). Hasil penelitian menunjukkan bahwa klonIRR 425, IRR 434, IRR 440, IRR 450, IRR 455 dan klon pembanding PB 260 tergolong moderat. Klon IRR 428, IRR 429 dan IRR 449 tergolong agak rentan, sedangkan klon IRR 431 dan IRR 451 tergolong rentan. Nilai heritabilitas pada delapan hari setelah inokulasi tergolong tinggi, hal ini menandakan bahwa tingkat ketahanan genetik klon IRR seri 400 terhadap penyakit daun Corynepora lebih dipengaruhi faktor genetik dibandingkan pengaruh lingkungan.
UJI SERAPAN HARA N PADA APLIKASI PUPUK KOMPOS SAMPAH ORGANIK DAN PUPUK MAJEMUK DENGAN MEDIA TANAH ULTISOL TERHADAP PERTUMBUHAN BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.) DI MAIN NURSERY Ingrid Ovie Yosephine; Sri Murti Tarigan; Yoemas Brillian Tarigan

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pemberian pupuk kompos sampah organik dan pupuk majemuk (NPK) terhadap pertumbuhan vegetatif tanaman dan serapan hara N tanaman pada pembibitan utama kelapa sawit. Penelitian ini dilaksanakan di areal Pembibitan Sekolah Tinggi Ilmu Pertanian Agrobisnis Perkebunan Medan dan Laboratorium Sentral Fakultas Pertanian Univeristas Sumatera Utara pada bulan Desember 2019 sampai Juli 2020. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 2 Faktor yaitu Faktor 1 yaitu  Kompos Organik Sampah Pasar dan Faktor 2 yaitu Pupuk Majemuk (NPK) 16:16:16 dengan ulangan 3x dengan jumlah tanaman per plot 2 tanaman, jumlah polybag keseluruhan adalah 54 polybag. Pengujian parameter disusun daftar Sidik Ragam atau Uji Analysis of Variance (ANOVA) dengan taraf 5% dan 1% dan dialnjutkan dengan Uji Duncan’s Multiple Range Test (DMRT) pada taraf 5%. Hasil menunjukkan bahwa perlakuan kompos organik sampah pasar dan pupuk majemuk berpengaruh nyata terhadap parameter yang diamati yaitu tinggi bibit (cm), jumlah daun (helai), berat basah akar (gr), berat kering akar (cm), berat basah tajuk (gr), berat kering tajuk (gr). Namun tidak berpengaruh nyata terhadap Lingkar batang (cm) dan serapan hara N (%).
