Penggunaan Pupuk Multihara Lengkap PML-A gro terhadap Pertumbuhan dan Hasil Cabai Merah

Holil Sutapradja

Abstract


ABSTRAK. Percobaan dilaksanakan di Kebun Percobaan Wera, Subang, dari bulan Mei sampai November 2005, dengan tujuan mendapatkan dosis dan formula pupuk tablet dan pupuk tepung PML-Agro yang tepat untuk meningkatkan hasil cabai merah dan efisiensi aplikasi unsur hara tanaman. Percobaan menggunakan rancangan petak terpisah dengan 3 ulangan. Perlakuan terdiri dari bentuk pupuk PML-Agro sebagai petak utama, sedangkan dosis dan formula pupuk PML-Agro dan pupuk tunggal sebagai anak petak. Hasil percobaan menunjukkan bahwa perlakuan pupuk PML-Agro 2 (600 kg/ha) dan kombinasi pupuk PML-Agro 1 (150 kg/ha)+PML-Agro 3 (150 kg/ha) menghasilkan buah cabai merah tertinggi, meskipun tidak berbeda nyata dengan kombinasi pupuk tunggal (Urea, ZA, TSP, KCl, dan dolomit). Peningkatan hasil dari kedua pupuk tersebut masing-masing sebesar 16,38 dan 11,41%. Penggunaan pupuk tablet dan tepung tidak berpengaruh terhadap pertumbuhan dan hasil tanaman cabai merah. Pemberian pupuk PML-Agro 1 (150 kg/ha)+PML-Agro 3 (150 kg/ha) baik dalam bentuk tablet maupun tepung dapat dianjurkan, karena lebih efisien dari penggunaan pupuk PML-Agro 2 (600 kg/ha) maupun pupuk tunggal (Urea, ZA, TSP, KCl, dan dolomit) dengan efisiensi penggunaan hara makro primer 25% lebih rendah daripada pupuk tunggal. Teknologi pemupukan yang dihasilkan ini lebih menguntungkan karena penggunaan pupuk yang efisien dan daya hasil meningkat.

ABSTRACT. Sutapradja, H. 2008. Application of PML-Agro Complete Multinutrient Fertilizer on Growth and Yield of Hot Pepper.This experiment was conducted at Wera, Subang Experimental Garden, started from May to November 2005, to find out the proper dosage and formulation of tablet and powder fertilizers to increase yield of hot pepper and nutrient efficiency. The experiment was arranged in a split plot design with 3 replications. The treatment consisted of PML-Agro fertilizer as main plot, and dosage formulation of PML-Agro fertilizer and combination of single fertilizers as subplot. The results showed that PML-Agro 2 fertilizer (600 kg/ha) and combination of PML-Agro 1 fertilizer (150 kg/ha)+PML-Agro 3 fertilizer (150 kg/ha) produced highest yield of hot pepper, although both treatments were not significanly different from the combination of single fertilizers (Urea, ZA, TSP, KCl, and dolomit). Yield increased due to the application of both fertilizers were 16.38% and 11.41% respectively. Application of tablet and powder fertilizers did not significantly affect the growth and yield of hot pepper. Combination of PML-Agro 1 fertilizers (150 kg/ha)+PML-Agro 3 fertilizer (150 kg/ha) in tablet and powder forms seemed to be more applicable for farmers, since they were more efficient than those of PML-Agro 2 (600 kg/ha) fertilizer and combination of single fertilizers (Urea, ZA, TSP, KCl, and dolomit) with efficiency of macro nutrient application about 25% lower than that of single fertilizer application. The use of PML-Agro fertilizer was more profitable due to its efficiency and yield improvement.
