This study aims to look at the interaction of PPC administration with different concentrations and different spraying frequency and get the best combination of the growth of oil palm seedlings were planted in peat media are flooded periodically. This research has been carried on in the greenhouse UPT Faculty of Agriculture, University of Riau, Pekanbaru, from November 2013 to February 2014. This study used a completely randomized factorial design consisting of two factors and three replications. The first factor was the concentration of PPC consists of 4 levels K0: no PPC, K1: 0.2%, K2: 0.4%, K3: 0.6% and the second factor the frequency of spraying PPC F1 consists of 3 levels: 1 times, F2: 2 times, F3: 3 times. Parameters measured were plant height increase, in the number of leaves, stem diameter, length of the primary root, root number, root volume, shoot root ratio. The mean separation of the tested by Duncan's multiple range test at 5%. The results showed the effect of interaction between the concentration and frequency of spraying PPC parameters contained in the stem base diameter, but not in the parameters as height of plants, increase the number of leaves, the primary root length, number of roots, root volume and shoot root ratio. A PPC concentration of 0.2% to 2 times, spraying showed the best growth at high accretion seed, in the number of leaves and root crown ratio, a PPC concentration of 0.6% with 3 times, spraying showed the best growth in root length, 1 time spraying on a number of roots, and 2 times spraying on the root volume.

This research aims to gain palm oil seed that fulfill quality standard while give liquid complementary fertilizerthough the seeds that stressed by flooding. The research was done in a Completely Randomized Design 3x3 and 3 replication. The first factor is seeds age, there are u0 = 3 months, u1 = 5 months, and u2 = 7 months age of palm oil, and the second factor is concentrate of liquid complementary fertilizer, there are p0 = 0 ppm, p1 = 6 ppm, and p2 = 12 ppm. Data were analyzed by analysis of variance andfurthertestedusingDuncan`sNewMultiple RangeTestatthe level of 5%,to decide criteria of seeds quality used standard of seeds quality according to Sihombing (2013). The result of research shows that there is no interaction between seeds age and concentrate of liquid complementary fertilizer on all observation variable. Seeds which is 5 months old and have stressed by flooding fulfill standard of seeds quality, but seeds which is 3 months and 7 months old don’t fulfill the standard of seeds quality only on height diference seeds. The ratio of roots, dry weight of seeds, and standard index of palm oil seed that stressed by floodingare better if we give liquid complementary fertilizer in 6 to 12 ppm. Key words : Palm oil seeds, flooding stress,liquid complementary fertilizer, growth.

The objective of this research was increase yield components and physiological seed quality and determined the proper dose of phosphorus fertilizer on four sorghum varieties. This research has been conducted in Field Experiment and the plant breeding laboratory, Faculty of Agriculture, University of Riau, from April 2014 to October 2014. The research conducted by using randomized block design (RBD) which arranged factorial with 2 factors and 3 replications. The first factor was a fertilizer dose of SP-36, namely: 45 kg SP-36, 90 kg SP-36 kg and 135 kg SP-36 / ha. The second factor was the sorghum varieties those Kawali, Numbu, Pahat and Mandau. The mean separation of analysis of variance was tested using Duncans multiple range test at 5%. Parameters those observed: seed weight / panicle, weight of 1000 seeds, seed weight/m2, seed moisture content, germination test, first count test, rate of germination, seedling dry weight, plumule growth and radicel test. The results showed that phosphorus fertilizer increases the grain weight / panicle, weight of 1000 seeds and seed weight/m2.The phosphorus fertilizer application of 90 kg/ ha showed the best effect on the variety Pahat (8,50 ton/ha) and Mandau (8,7 ton/ha). The Phosphorus fertilizer application increases the physiological seed quality on all parameters except the water content.The phosphorus fertilizer application 135 kg/ha gave the best quality of the seed physiology of Mandau and Numbu.
