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

Tujuan penelitian untuk mengetahui pengaruh efektivitas gulma Ludwigia parviflora dan Portulaca oleracea dalam mengendalikan gulma Eleusine indica di lahan budidaya cabai. Penelitian ini menggunakan rancangan acak kelompok dengan 9 perlakuan dan 3 ulangan. Perlakuan yang digunakan yaitu P0 = kontrol, P1 = L. parviflora 25%, P2 = P. oleracea 25%, P3 = L. parviflora 50%, P4 = P. oleracea 50%, P5 = L. parviflora 75%, P6 = P. oleracea 75%, P7 = L. parviflora 100%, dan P8 = Portulaca oleracea 100%. Parameter pengamatan yaitu mortalitas gulma, tinggi gulma, jumlah daun gulma, berat basah pupus gulma, berat kering pupus gulma, berat basah akar gulma, berat kering akar gulma, tinggi cabai dan jumlah daun cabai. Hasil penelitian menunjukkan bahwa perlakuan pengamatan P8 pada parameter pengamatan mortalitas gulma 4 MSPT, 6 MSPT perlakuan tinggi gulma 2 MSPT, dan 4 MSPT  berbeda nyata dengan perlakuan lainnya. Perlakuan pengamatan jumlah daun gulma 2 MSPT, 4 MSPT dan 6 MSPT, tinggi tanaman cabai 2 MSPT, 4 MSPT dan 6 MSPT dan jumlah daun cabai 2 MSPT, 4 MSPT, dan 6 MSPT tinggi gulma 6 MSPT, berat basah pupus gulma, berat kering pupus gulma, berat basah akar gulma dan berat kering akar tidak berbeda nyata terhadap perlakuan lainnya.
