PENGARUH TEGANGAN AIR TERHADAP EFISIENSI PEMUPUKAN N, P, DAN K PADA TANAMAN PADI GOGO LOKAL VARIETAS KALPATALI (Oryza sativa L.) DI TANAH ULTISOL
Abstract: This research is
held at the greenhouse of Faculty of Agriculture, University of Riau, Pekanbaru
starts in March to August 2016. The
trial uses the factorial of Complete Random Program (RAL). The first factor of
the water tension comprises of three levels, they are : (pF 1 - 1,97), (pF 2,29
- 2,54) and (pF 2,70 - 3) and the second factor of the fertilization dosage
of N, P, and K which comprises of four
levels without fertilization of N, P, and K, given ½ x recommended dosage,
given recommended dosage, and given 1½ x recommended dosage. The process is
repeated three times. The data of observation result could be statistically
analysed with ANOVA and followed by Duncan test at 5% level. The observed
parametre are nutrients uptake of N, P and K, the efficiency of absorption of
N, P, and K, height of plants, phase of malai's appearances, number of
productive tiller, ratio of stem and root,
period of harvest, weight of 1000 paddy seeds and product efficiency.
The result of this research shows the interaction of water tension and
fertilisation dosage of N, P, and K visibly influnce the nutrients of N, P, and
K, height of plants, ratio of stem and
root, and weight of 1000 paddy seeds. Invisibly influence to the phase of
malai's appearances, period of harvest, and number of productive tiller.
Combination of water tension pF 1 - 1,97 and fertilization dosage 1 ½ x
recommeded dosage are the best combinations.
