SKRIPSI PENGARUH KONSENTRASI PUPUK DAN ORGANIK TRESS PADA HASIL BEBERAPA VARIETAS SELADA (Lactuca Sativa L.)
ABSTRACT
Research entitle the influence of concentration leaf manure organic Tress on the yield of several varieties Lec ttuce (Lactuca sativa L.), has been carried out from June 6 th 1994 until July 15 th 1994 in Tonoboyo village, Ban- dongan district, Magelang Regency, Central Java. The alti- tude was 650 meters above sea level at the latosol soil with pH 6. The research method used was split plot design based
on complete group random design, cosists of 2 factors and 3 repetition. Factor 1. Several Varieties of Lecttuce (V) as main plot consists of 3 levels.
V1: Variety of White Boston V2: Variety of Great Lake
V3: Variety of Grant Rapid
Faktor 2. Concentration of leaf manure organic Tress (K) as sub plot consists of 4 koel.
Ko: 0 cc/1 litre of Concentration
K1: 0,625 cc/1 litre of Concentration
K2: 1,25 cc/1 litre of Concentration
K3 1,875 cc/1 litre of Concentration The result of the research showed that concentration
of Organic Tress obviously influence to high of plant, num ber of leaves, longest lef, gross weight, the net weight of every plant, the moment of crop formed, the diameter of a crop and both of them there is no obvious in teraction, Between variety of lecttuce gave no significant on crop formation, the diametre of crop, Obviousdy differant on height of plant, number of leaves, longest leaf, gross
weight and net weight every plant. The treatment concentration of Tress of 1,25 cc/1 11- tre (K2) on variety of great lake (V2) indicated the hig- hest net weight of every plant with average weight 354,83 gram but concentration of Tress O0 cc/1 litre on variety of White Boston (V1) indicated the lowest with average weight 167,08 gram.
