RESPON TANAMAN BAWANG MERAH (Allium ascolonicum L.) VARIETAS TUK TUK TERHADAP PENGATURAN JARAK TANAM DAN KONSENTRASI PUPUK ORGANIK CAIR NASA
ABSTRACT: The research
objectives are to: (1) study the response of the red onion upon the plant
spacing and application of Nasa liquid organic fertilizer (POC) concentrations
and their interactions, and (2) to obtain the proper plant spacing and Nasa POC
concentration for red onion crop. The study was conducted from May to September
2011 start of preparation, data collection, analysis and report writing.
Research site is in the South Sempaja Urban village, Sub district of North
Samarinda, Samarinda. Completely Randomized Block Design was applied for this
study, using 4 x 4 factorial pattern with 3 replications. The first factor was
the plant spacing (J) consists of: 10cm x 15cm (j1), 15cm x 15cm (j2), 15cm x
20cm (j3), and 20cm x 20cm (j4). The second factor was the Nasa POC (P)
consists of: no POC Nasa application or 0 ml l -1 water (p0) , 1 ml l -1 water
(p1), 2 ml l -1 water (p2), and 3 ml l -1 water 1 (p3). Analysis of the data
using analysis of variance, when the results were significantly different (F
count > F table 5%) or very significant (F count > F table 1%), then to compare
the two treatments used the least significant difference test at level of 5%.
The results showed that: (1) the responses of plant height at age 20 and 60
days after planting, the number of leaves at age of 40 and 60 days after
planting, and tuber production are significantly different to highly
significant upon the plant spacing. The highest tuber production was attained
at plant spacing of 10cm x 15cm (j1), with 11.72 Mg ha -1 ; (2) responses of
plant height at age 20, 40 and 60 days after planting, the number of leaves at
age 20, 40 and 60 days after planting, the number of tillers at the age of 40
and 60 days after planting, tuber weight per plot, and the production of tubers
are significantly different upon the Nasa POC concentration. The highest tuber
production was attained at Nasa POC treatment with concentrations of 3 ml l -1
water (k4), with 9.12 Mg ha -1 , and (3) there is no interaction between the
plant spacing and Nasa POC concentration on all parameters observed.
