PENGARUH URINE SAPI TERFERMENTASI DENGAN DOSIS DAN INTERVAL PEMBERIAN YANG BERBEDA TERHADAP PERTUMBUHAN TANAMAN SAWI (Brassica juncea L.)
ABSTRAK: A
research was conducted at research farm of Agriculture and Animal Science
Faculty of State Islamic University Sultan Syarif Kasim Riau from April to June
2011. The objective of this research was to determine a combination of
concentration and application interval of cow’s urine that maximizes the growth
of chinese cabbage (Brassica juncea L.). Combinations of four cow’s urine
concentration (0, 15%, 30% and 45%) and three application intervals (every 2, 3
or 4 days) were arranged in Randomized Complete Block Design (RCBD) wirh 3
replications. The experiment was conducted in pots with peat soil The plants
were harvested at 40 days and data were collected for plant height, number of
leaves/plant, leaf length (measured for the longest leaf), shoot fresh weight
and shoot dry weight. Results of the research showed that there were no changes
in plant height, number of leaves/plant and leaf length was observed for
different application intervals. However, the increase of every 15% of cows’
urine concentration increased 2.7 cm plant height, 1.2 leaves/plants, and 1.5
cm leaf length. Significant interaction of concentration and application
interval was observed for shoot fresh weight and shoot dry weight. A
combination of 45% concentration and 2 days application interval produced the
best shoot fresh weight and shoot dry weight, but there was no effect of
application interval on 15% concentration.
