Respon Pertumbuhan Sawi Pakcoy (Brassica rapa L.) Var. Astri Terhadap Dosis Kompos Daun Lamtoro, Kulit Pisang dan Cangkang Telur

Abstract

Penggunaan pupuk anorganik secara terus menerus menyebabkan penurunan kesuburan tanah dan terganggunya mikroorganisme dalam tanah. Solusi untuk meninimalkan dampak dari pemakaian pupuk anorganik salah satunya yaitu penggunaan pupuk kompos dari campuran bahan organik seperti daun lamtoro, kulit pisang, dan cangkang telur. Penelitian ini bertujuan untuk mengetahui pengaruh dosis pupuk kompos daun lamtoro, kulit pisang, dan cangkang telur terhadap pertumbuhan dan hasil sawi pakcoy. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan faktor dosis pupuk kompos daun lamtoro, kulit pisang, dan cangkang telur yaitu P1 (0 gram/ tanaman), P2 (20 gram/ tanaman), P3 (40 gram/ tanaman), P4 (60 gram/ tanaman), P5 (80 gram/ tanaman). Masing-masing perlakuan diulang sebanyak lima kali. Hasil penelitian menunjukkan bahwa perlakuan dosis kompos berpengaruh nyata terhadap tinggi tanaman, jumlah daun, luas daun, bobot akar basah, bobot akar kering, bobot tajuk basah, bobot tajuk kering, bobot brangkasan basah, dan bobot brangkasan kering, tetapi tidak berpengaruh nyata terhadap total klorofil. Perlakuan dosis kompos 80 gram/ tanaman memberikan hasil terbaik dalam memacu komponen pertumbuhan dan hasil sawi pakcoy.

Continuous use of inorganic fertilizers causes a decrease in soil fertility and disruption of microorganisms in the soil. One of the solutions to minimize the impact of using inorganic fertilizers is using compost from a mixture of organic materials such as lamtoro leaves, banana peels, and egg shells. This research aims to determine the effect of doses of lamtoro leaf compost, banana peels and egg shells on the growth and yield of pakcoy mustard greens. This study used a randomized block design (RBD) with dosage factors of lamtoro leaf compost, banana peels, and eggshells, namely P1 (0 gram/plant), P2 (20 gram/plant), P3 (40 gram/plant), P4 ( 60 grams/plant), P5 (80 grams/plant). Each treatment was repeated five times. The results showed that the compost dosage treatment had a significant effect on plant height, number of leaves, leaf area, wet root weight, dry root weight, wet crown weight, dry crown weight, wet stover weight, and dry stover weight, but had no significant effect on the total chlorophyll. Treatment with a compost dose of 80 grams/plant gave the best results in stimulating growth components and yields of pak choy mustard greens.
