Abstract :
DELAYUNISA, The effect of giving types of biological fertilizers and
humic acid dose on the growth and production of shollot plasts (Allium
ascalonicum L.) (guided by mother ROSMIAH and mother HENIYATI
HAWALID). This study aims to determine and determine the types of biological
fertilizers and humic acid doses that can provide thr best groth and produktion for
onion plants (Allium ascalonicum L.). This research has been carried out in the
landowned by farmers who are in the vilangge of Steko Indaralaya, Nort Ogan Ilir
Regency Sumatra 32 km. Resrarch time is from june to july 2019. The research
method used was a Split Plot Design with eight treatment combination and three
replications. Main plot is a type of biological fertilizer (H) H1 biophosphate and
H2 mycorrhizae, as a sub plot is adose of humic acid fertilizer (A) A0 =(without
fertilizer), A1 = 25 kg/ha (5g/plot), A2 = 50 kg/ha(10g/plot), A3 = 75 kg/ha
(15g/plot).The observed variables were plant height (cm), number of leaves
(strands), numberof tillers per clum (g), numbe of tumbers per clump (gloves),
fresh weight per clump (g), tuber weight per plot (kg). Based on the results of
diversity research showed tha the treatment of mycorrhizal species significantly
affeted the number of tillers per clump, number of tubers per clump and the dose
of humic acid 75 kg/ha had a significant effect oh the number oftillers per clump,
number of tubers per clump, tuber weight per plot but affected no effect on the
observed variables. The interaction treatment did not significantly affect al
observed variables.
