Uji Tinggi Muka Air Tanah Gambut Dan Pemberian Abu Sekam Padi Terhadap Pertumbuhan Dan Produksi Tanaman Padi Gogo (Oryza Sativa L.)
The purpose of this study was to determine the interaction of ground water
level and the administration of rice husk ash to the growth and production of
upland rice (Oryza sativa L.) in peat soils. This research was conducted at the
UPT Gauze House Experimental Garden Faculty of Agriculture, University of
Riau in March to June 2018. This study used a factorial complete randomized
design (RAL) consisting of 9 treatments and 3 replications. The first factor is the
depth of the ground water level consisting of 3 levels, namely 30 cm, 40 cm, 50
cm and the second factor is the provision of rice husk ash which consists of 3
levels namely 18,75 g/paralon, 37,50 g/paralon, 56,25 g/paralon. The parameters
observed were plant height, maximum number of tillers, panicle length,
percentage of productive tillers, number of rice grains per panicle, percentage of
rice grains, weight of 1000 grains and grain dry weight per clump. The data
obtained were analyzed using variance analysis and continued with DNMRT test
at 5% level. Variance test results showed that the interaction between peat ground
water level and the administration of rice husk ash were not significantly different
in all characters observed except the number of rice grains per panicle and grain
dry weight per clump and the average comparison test results showed high
combinations 40 cm peat soil water level and 7,5 tons/ ha-1 of rice husk ash can
give the best results on the parameters of the maximum number of tillers (22,33
stems), 1000 grain weight (26,25 g), and grain dry weight per family (71,00 g).
