Abstract

Cayenne pepper is known as one of main commodities which is often used as food seasoning in Indonesia. The growth of cayenne pepper plant is strongly influenced by fertilizer application. It is because the addition of fertilizer will increase the productivity of cayenne pepper. This research  had aim to determine the effect of NPK fertilizer dosage on cayenne pepper vegetative growth at marginal field. This study used a non-factorial randomized block design (RAK) with 5 replications. The treatments were conducted i.e. P0 = Control, P1 = 2.5 grams of NPK, P2 = 5 grams of NPK, P3 = 7.5 grams of NPK, and P4 = 10 grams of NPK. Parameters were observed i.e. plant height, stem diameter, number of leaves, leaf width, leaf length and number of flowers. The data were analyzed using ANOVA, then it were  continued with  DMRT test. The results showed that the dose of NPK fertilizer had a significant effect in line with the increase in the dose of NPK on the vegetative growth of cayenne pepper plants. The Application of NPK fertilizer 10 grams on plant height was 29.37% higher than without treatment. The Application of NPK fertilizer 10 grams on plant stem diameters was 25.86% wider than it was without treatment. The Application of NPK fertilizer 10 grams on the number of leaves was 36.89% more than it was without treatment. The Application of NPK fertilizer 10 grams on leaf width was 16.25% wider than it was without treatment. The Application of NPK fertilizer 10 grams on leaf length was 23.97% longer than it was without treatment. The Application of NPK fertilizer 10 grams on the number of flowers was 90.93% more than it was without treatment. The P4 treatment, i.e. the application of NPK fertilizer 10 grams, was the best treatment for all vegetative growth parameters of cayenne pepper plants.

Abstract

Cabai merupakan tanaman hortikultura yang banyak ditanam oleh petani di Kota Tarakan karena cabai memiliki nilai ekonomi yang tinggi dan kendala budidaya tanaman cabai yaitu kehadiran gulma. Kehadiran gulma pada lahan budidaya tanaman cabai berdampak kepada berkurangnya hasil produksi tanaman cabai. Gulma yang sering dijumpai lahan budidaya cabai petani di Kota Tarakan yaitu gulma Eleusine indica Salah satu cara untuk mengendalikan gulma Eleusine indica di lahan budidaya cabai yaitu pemberian herbisida alami. Herbisida alami yang digunakan dalam penelitian ini adalah gulma Cyperus compressus dan Eleusine indica. Tujuan penggunaan herbisida alami yaitu dapat menekan pertumbuhan pertumbuhan gulma Eleusine indica di lahan budidaya cabai. Penelitian menggunakan rancangan acak kelompok dengan 1 faktor dengan 9 perlakuan dan diulang 3x, Perlakuan yaitu P0 (Kontrol), P1 (25% Cyperus compressus), P2 (25% Eleusine indica), P3 (50% Cyperus compressus), P4 (50% Eleusine indica), P5 (75% Cyperus compressus), P6 (75% Eleusine indica), P7 (100% Cyperus compressus), dan P8 (100% Eleusine indica). Parameter pengamatan yaitu mortalitas gulma, tinggi cabai, jumlah daun cabai, tinggi gulma, jumlah daun gulma, berat basah pupus gulma, berat kering pupus gulma, berat basah akar gulma, dan berat kering gulma. Data dianalisis menggunakan ANOVA, apabila terdapat data berbeda nyata maka dilanjut dengan uji lanjut Duncan. Hasil penelitian menunjukkan bahwa semua parameter pengamatan vegetatif tanaman cabai dan gulma tidak berbeda nyata. Perlakuan P5 (75% Cyperus compressus) memiliki kemampuan menekan pertumbuhan gulma terbaik pada pengamatan tinggi gulma jumlah daun cabai, berat basah pupus cabai, berat kering pupus cabai, berat basah akar cabai dan berat kering akar cabai, Perlakuan P7 (100% Cyperus compressus) memiliki perlakuan terbaik pada tinggi tanaman cabai dan jumlah daun cabai.Kata kunci: Cabai, Cyperus compressus, Eleusine indica, Gulma
