Abstract

Penelitian ini dilaksanakan pada bulan Juli 2022, di perkebunan Kelapa Sawit Desa Pondok Bungur Kecamatan Rawang Panca Arga Kabupaten Asahan Sumatera Utara. Penelitian bertujuan mengetahui Efek Pertumbuhan Tanaman Jagung terhadap Aspek Agronomi di Bawah Naungan Kelapa Sawit. Penelitian ini menggunakan Rancangan Acak Kelompok Faktorial dengan dua faktor dan tiga ulangan. Perlakuan pertama terdiri dari Tingkat penaungan (P) dengan 4 taraf perlakuan yaitu (P0) Tanpa penaungan, (P1) penaungan 35%, (P2) penaungan 70%. Perlakuan kedua terdiri dari Varietas jagung (J) dengan 6 varietas yaitu Varietas Exsotic Pertiwi (V1), Paragon (V2), Bonanza F1 (V3), Bisi 2 (V4). Hasil penelitian menunjukkan tanaman yang tertinggi 113,98 cm terdapat pada perlakuan yang diberi naungan 35%, sedangkan pada penggunaan Varietas Bisi-2 tanaman tertinggi yaitu 112,83 bila dibandingkan dengan varietas lainnya. Penggunaan varietas berpengaruh nyata terhadap luas daun pada umur 6 dan 8 minggu setelah tanam. Persentase tingkat penaungan dan perbedaan varietas menunjukkan kesamaan kualitas kehijauan daun. Tingkat penaungan menunjukkan pengaruh yang nyata terhadap klorofil-a dan total klorofil-a dan b dimana jumlah klorofil-a tertinggi terdapat pada blok kontrol yaitu tanpa naungan dan pada penaungan 70%. Sedangkan penggunaan beberapa varietas berpengaruh nyata dalam menghasilkan fotosintesis bersih yang terbentuk.

Abstract

The study  aimed to determine the agronomic study of the tolerance of corn plants to conditions shaded by oil palm trees. This research was conducted from July to October 2022. At the Oil Palm Plantation of the Community of Bunut Seberang Village, Asahan Regency, North Sumatra. This study used a factorial randomized block design with two factors and three replications. The first treatment consisted of a shading level (P) with 4 treatment levels namely (P0) without shading, (P1) 35% shading, (P2) 70% shading. The second treatment consisted of a variety of corn (J) with 6 varieties, namely Exsotic Pertiwi (V1), Paragon (V2), Bonanza F1 (V3), Bisi 2 (V4) varieties. The best plant height parameter in the shade level treatment showed 35% shade (P1) resulted in the highest plant height of 113.98 cm, while in the Variety (V4) Bisi-2 variety treatment showed the highest plant, namely 112.83 when compared to other varieties. The effect of various varieties on leaf area showed a significant effect at the age of 6 and 8 WAP. The degree of shade and differences in varieties show the similarity in the quality of the green leaves. The level of shade showed a significant effect on chlorophyll-a and total chlorophyll-a and b where the highest amount of chlorophyll-a was found in the treatment without shade, which was not significantly different from the level of 70% shade, while varieties had a significant effect in producing net photosynthesis formed
