Abstract

Sweet corn (Zea mays saccharata L.) is a plant that contains more carbohydrates so that it becomes one of the second most important commodities after rice, both as a source of food and feed. The objectives of this study were to obtain the best Paclobutrazol Concentration on the Growth and Yield of Sweet Corn on Peat Soil in Rasau Jaya 2 and to obtain the best Planting System on the Growth and Yield of Sweet Corn on Peat Soil in Rasau Jaya. The research was conducted on Mr. Sugianto's land located at Patok 28, Rasau Jaya 2 Village, Rasau Jaya District, Kubu Raya Regency. This research took place from July 24, 2023 - September 30, 2023. This study used a Split Plot Design consisting of 2 factors. The first factor is the concentration of Paclobutrazol (P) which consists of 4 treatment levels and the second factor is a modified double row planting system (D) with 3 treatment levels, so that the total treatment combination is 12. Each treatment combination was repeated 3 times and each treatment unit consisted of 5 plant samples.  In the Split Plot Design, Paclobutrazol concentration (P) was used as the main plot, while the modified double row planting system (D) was used as a sub plot. The observed variables were plant height, stem diameter, number of leaves, plant fresh weight, plant dry weight, leaf area, root volume, ear weight per plot, weight of ear, weight of ear without shell, weight per ear without shell, ear with shell and ear without shell. Observation data were statistically analyzed using variance (F test at 5% level). If the F test showed a real effect, then the Honestly Significant Difference (HSD) test was continued at the 5% level. On the basis of the results of the study, it can be concluded that the single application of paclobutrazol can suppress the plant height but has the same effect of reduction of plant height by 3-5 cm. The planting system (15+15) cm x 80 cm with the use of paclobutrazol 1000 ppm can increase the weight of cob per plot better than other planting systems. Keywords: Soil, Sweet Corn, Paclobutrazol, Planting System. INTISARIJagung manis (Zea mays saccharata L.) merupakan tanaman yang mengandung karbohidrat lebih banyak sehingga menjadi salah satu komoditi terpenting kedua setelah padi, baik sebagai sumber pangan maupun pakan. Tujuan penelitian ini adalah untuk mendapatkan Konsentrasi Paclobutrazol terbaik terhadap Pertumbuhan dan Hasil Jagung Manis pada Tanah Gambut di Rasau Jaya 2 dan untuk mendapatkan Sistem Tanam terbaik terhadap Pertumbuhan dan Hasil Jagung Manis pada Tanah Gambut di Rasau Jaya. Penelitian dilaksanakan di lahan Bapak Sugianto yang berada di Patok 28, Desa Rasau Jaya 2, Kecamatan Rasau Jaya, Kabupaten Kubu Raya. Penelitian ini berlangsung dari tanggal 24 Juli 2023 – 30 September 2023. Penelitian ini menggunakan Rancangan Petak Terbagi (Split Plot Design) yang terdiri dari 2 faktor. Faktor pertama yaitu konsentrasi Paclobutrazol (P) yang terdiri dari 4 taraf perlakuan dan faktor kedua adalah modifikasi Sistem Tanam double row (D) dengan 3 taraf perlakuan, sehingga total kombinasi perlakuan sebanyak 12 . Setiap kombinasi perlakuan diulang sebanyak 3 kali dan masing-masing unit perlakuan terdiri 5 sampel tanaman.  Pada rancangan Split Plot Design konsentrasi Paclobutrazol (P) dijadikan petak utama (main plot), sedangkan modifikasi Sistem Tanam double row (D) dijadikan sebagai anak petak (sub plot). Variabel yang diamati yaitu tinggi tanaman, diameter batang, jumlah daun, bobot segar tanaman, bobot kering tanaman, luas daun, volume akar, bobot tongkol per petak, bobot per tongkol berkelobot, bobot per tongkol tanpa kelobot, panjang tongkol dan diameter tongkol. Data hasil pengamatan dianalisis secara statistik dengan menggunakan varians (uji F taraf 5%). Apabila uji F menunjukkan adanya pengaruh nyata, maka dilanjutkn uji Beda Nyata Jujur (BNJ) pada taraf 5%. Berdasarkan hasil penelitian maka dapat disimpulkan bahwa pemberian paclobutrazol secara tunggal dapat menekan tinggi tanaman namun memberikan pengaruh yang sama pengurangan tinggi tanaman 3-5 cm. Sistem tanam (15+15)cm x 80 cm dengan penggunaan paclobutrazol 1000 ppm dapat meningkatkan bobot tongkol perpetak lebih baik dibandingkan sistem tanam lainnya. Kata Kunci : Gambut, Jagung Manis, Paclobutrazol, Sistem Tanam.
