SKRIPSI KAJIAN MACAM PUPUK DAUN DAN FREKUENSI PEMBERIAN TERHADAP PERTUMBUHAN BIBIT ALPUKAT (Persea americana Mill)
ABSTRACT
The experiment wes conducted from March to Juni 1993, on Potrobangsan, Magelang, Central Java, take the matter of regosol soil, pH 6,5 at on altitude of 375.
The research wes purposed to know the effect of a kind leaf fertilizer and the seedling growh frequency of avocado (Persea americana Mill).
The experimental method used the factorial wiht system Which was based on A Randomized Complete Block Design (RCBD), with 2 factor wes a kind leaf fertilizer at 5 level and frequency at 3 level. The fist factor wes a kind leaf
fertilizer Po Not treatment
P Manure Grow Morre, consentration 2 g/1
P 1 Manure Gemari, consentration 3 00/1
P: Hanure Handasil D, consentration 3 g/1
3 P manure Vitana, consentration 2,5 g/1. The scand factor
wes frequency F1: To fertilize each 7 day once, 30, 37, 44, 51, 58, 65. 72.
F: To fertilize each 14 day once 30, 44, 58, 72. 2 To fertilize each 21 day once 30, 51, 72.
3 Leaf fertilizer give very significant effects to the such as height of seedling, mount at leafes, top root lenght, number of branch root, fresh weight of seedling. dry weight of seedling, stem diameter and lenght of the leafes.
Fertilizing frequency give very significant effects to the height of seedling, mounnt of leafes, top root lenght, number of branch root, fresh weihht of seedling, dry weight of seedling sten diameter and lenght of the leafes.
The two treatment indicated significant intersction mount at leafes, fresh weight of seedling, and dry weight of seedling.
Fertilizing with leafes fertilizer of the frequency of once in 7 days, indicated highest in fluence of leafes fertilizer Grow Morre effect to mount of leafes, fresh weight of seedling, dry weight of seedling, sten dianeter and lenght of leafes, Mean while leafes fertilizer Gemari give heighest of the height of seedling, top root and number of branch root.
