Pengaruh Dosis Pupuk Organik Cair Daun Lamtoro terhadap Pertumbuhan dan Hasil Tanaman Pakcoy (Brassica rapa l.) Varietas Nauli-F1

Abstract

The research was conducted in Padasari Village, Cimalaka Sub-district, Sumedang District, from June to September 2018, located at an altitude of 600 m asl. The objective of experiment was to study the effect of dosage of lamtoro leaf organic fertilizer to growth and yield of Pakcoy (Brassica rapa L.) plant varieties Nauli-F1. The research was conducted by experimental approach through field experiment. The design used in the experiment was a simple randomized block design consisting of six treatments and four replications. The dose of liquid organic fertilizer treatment Lamtaro leaves consist of: A : 0 L Ha-1, B: 100 L Ha-1, C: 200 L Ha-1, D: 300 L Ha-1, E: 400 L Ha-1, and F: 500 L Ha-1. The result of experiment showed that the use of lamtoro liquid organic fertilizer gave a good effect on all observation variables. The dose of Lamtoro leaf organic fertilizer 500 L Ha-1 showed the best result an plant height, number of leaves, net weight per plant, net weight per plot, and the shoot root ratio.

The Effect of Seaweed (Sargassum sp.) and Plant Extract Combinations on the Growth of Mustard Plant (Brassica juncea L.) Grown in Hydroponic Wick System

“…Further research to find the best organic nutrition which has the same quality as AB mix is needed. According to Hidayat and Suharyana (2019) and Rop et al (2019), N contained in liquid organic fertilizer made from lamtoro leaves functions as a protein constituent, while the P and K in lamtoro leaves can stimulate meristem tissue division, stimulate root growth, leaf development so that N, P and K increase plant fresh weight and increasing crop production. Rambe (2014) stated that plants will survive if the nutrients needed by plants are available in a balanced proportion, especially macronutrients such as N, P and K both in soil and in organic matter.…”

The growth and yield responses of two bean cultivars to organic and inorganic nitrogen sources

“…Pramitasari et al (2016), stated that higher N absorption by plant leads to larger growth of the leaves. Furthermore, the application of LOF from leucaena leaves showed significant growth in plant height, numbers of leaves, and fresh weight of mustard greens (Pary 2015), the highest yield on the number of pakcoy leaves (Hidayat and Suharyana 2019), and increased the growth and number of fruit in tomato plants (Septirosya et al 2019). The number of trifoliate leaves is a plant characteristic that affects the rate of photosynthesis to capture sunlight.…”

Pengaruh Pupuk Organik Cair Daun Lamtoro (Leucaena leucocephala) dengan Daun Kelor (Moringa oleifera L.) terhadap Pertumbuhan dan Hasil Tanaman Cabai Rawit (Capsicum frutescens L.) Var. Dewata 43 F1

“…Hasil ini menunjukkan bahwa pemberian bahan organik dari pupuk organik cair daun lamtoro dengan daun kelor mempengaruhi pertumbuhan jumlah daun tanaman dan semakin tinggi dosis pemberian pupuk organik cair semakin banyak unsur hara yang diserap oleh tanaman. Hal ini sesuai dengan teori Hidayat & Suharyana (2019) bahwa pemberian pupuk organik cair daun lamtoro dapat memperbaiki aerasi tanah, menambah kemampuan tanah menahan unsur hara, meningkatkan kapasitas menahan air, meningkatkan daya sangga tanah, sumber energi bagi mikroorganisme tanah dan sebagai sumber unsur hara bagi tanaman.…”
