Abstract

Penelitian bertujuan mengetahui pengaruh macam naungan dan dosis pupuk nitrogen terhadap pertumbuhan bibit kakao (Theobroma cacao l.). Penelitian ini menggunakan rancangan acak kelompok lengkap (RAKL) yang disusun secara factorial dengan dua faktor. Faktor pertama adalah naungan yang terdiri dari perlakuan tanpa naungan (S0), atap rumbia (S1), atap plastic (S2), dan atap gedeg (S3), sedangkan faktor kedua adalah pupuk nitrogen yang terdiri dari dosis 0 gram Urea/bibit (N0), dosis 2,5 gram Urea/bibit (N1), dosis 5 gram Urea/bibit (N2), dosis 7,5 gram Urea/bibit (N3), dosis 10 gram Urea/bibit (N4). Pengamatan meliputi tinggi tanaman, jumlah daun,ndiameter batang, berat basah tajuk, berat kering tajuk, berat basah akar, berat kering akar.             Perlakuan pemupukan berpengaruh tidak nyata terhadap tinggi tanaman, diameter batang, berat basah akar, berat kering akar, tetapi berpengaru sangat nyata terhadap jumlah daun, berat basah tajuk dan berat kering tajuk. Perlakuan naungan berpengaruh sangat nyata terhadap semua parameter, yaitu tinggi tanaman, jumlah daun, diameter batang, berat basah basah tajuk, berat kering tajuk, berat basah akar dan berat kering akar. Hasil penelitian pengaruh dosis pupuk nitrogrn dan macam naungan  tidak terdapt interaksi terhadap pertumbuhan bibit kakao Kata Kunci : Tanaman kakao, Pupuk nitrogen, Macam naungan

Abstract

This study aimed to determine the interaction between Giberellin Plant Growth Regulator (ZPT) and NASA Liquid Organic Fertilizer (POC) and their effects on the growth of matoa seedlings (Pometia pinnata). This research was conducted in Talang Giring Village, Lubuk Sandi District, Seluma Regency, Bengkulu Province, from April to June, two-factor Randomized Complete Block Design (RCBD) was used. The first factor was Gibberellin ZPT (Z) with four concentration levels: Z0 (control), Z1 (30 ppm), Z2 (60 ppm), and Z3 (90 ppm). The second factor was NASA POC (P) with three concentration levels: P1 (5 ml/l), P2 (7.5 ml/l), and P3 (10 ml/l). There were 12 treatment combinations, replicated 3 times, resulting in a total of 36 experimental units. The observed parameters included plant height, number of leaves, number of roots, and root length. The analysis results indicated that there was no significant interaction between Giberellin ZPT and NASA POC for all observed parameters. The application of Gibberellin ZPT had a significant effect on plant height at 28 days after planting (DAP) and a highly significant effect on the number and length of roots. Meanwhile, the application of NASA POC had a highly significant effect on the number of leaves at 70 DAP and root length.
