Abstract

This study aimed to determine the effect of cow urine and NPK fertilizers, as well as getting the best dose on production component of sweet corn on peatlands. The research was conducted on peat types sapric in Experimental Farm, Faculty of Agriculture Rimbo Panjang TambangDistrict of Kampar Regency and conducted over three months starting in December 2015 to March 2016. The study was conducted using a factorial RAL consisting of two factors with the first factor is giving of cow urine U1: cow urine concentration of 150 ml/l, U2: cow urine concentration of 300 ml/l, U3: cow urine concentration of 450 ml/l and U4: cow urine concentration of 600 ml/l. The second factor is the NPK fertilizer is P0: without fertilizer NPK, P1: award NPK 150 kg/ha and P2: award NPK 300 kg/ha. Data were analyzed statistically using analysis of variance followed by Duncan's multiple range test at 5% level. Parameters measured were plant growth rate, production per plot, weight per cob without husk, cob without husk lengthand diameter cob without husk.The results showed interaction NPK fertilizer of cow urine and cow urine as well as single factor effect is not real to each parameter of observation. Giving a single factor NPK showed an increased rate of plant growth, production per plot, weight per cob without husk, without husk cob lengthand cob diameter without husk. Increased production of sweet corn is highest at a dose of 300 ml of cow urine treatment with NPK fertilizer 150 kg/ha of 6,53 kg/5,25 m2 (equivalent to 5,0 tons/ha), increased 83% compared with no fertilizer NPK and 150 ml cow urine. Keyword: Cow urine, NPK fertilizer and sweet corn

Abstract

This study aimed to determine the effect of organic liquid fertilizer and liquid organic fertilizer obtain a concentration corresponding to the growth of seedlings of oil palm (Elaeis guineensis Jacq). The main breeding and looking for correlations of all parameters in the treatment gives the highest influence on the main nursery. Completely randomized design (CRD), consisting of 5 treatments with 4 replications. Data were  analyzed by analysis of variance, HSD (Honestly Significant Difference) at 5% level and correlation was used in this research. The parameters were observed in the study were plant height increment, the increase in diameter stump, in the number of leaves, root volume, fresh weight and dry weight. Liquid organic fertilizer significantly affects on plant height increment parameter, the increase in diameter stump, root volume, fresh weight and dry weight of oil palm seedlings, but no significant difference in the parameter number of leaves. Organic fertilizer at a concentration of 6 ml / l of water showed the highest value on each parameter observation that a high increment of plants, increase the diameter of the pulpit, in the number of leaves, root volume, fresh weight and dry weight of oil palm seedlings than other concentration.   Keywords : organic liquid fertilizer, palm oil, concentration

Abstract

This research aims to determine the influence of the concentration of coconut water, to find out the best concentration for the growth of seedlings of robusta coffee plant and look for correlation of all parameters on the treatment that gives the highest growth. This research has been carried out in the UPT area of research farm in the faculty of agriculture, University of Riau. This research was conducted in June to September. This design of this research was completely random design, 5 treatments and 4 replications. Each research unit consists of 3 plants, thus the number of sources used as many as 60 robusta coffee seeds. The results showed that an increase in the concentration of coconut water also improves the increment of plant height, the increase in the circumference of the trunk, broad leaves, root header ratio and dry weight of the plant. The results showed that an increase in the concentration of coconut water doesn't improve the increment of the number of leaves. Treatment of the application of the coconut water with a concentration of 50% gives the highest influence for the increment of plant height, the increase in the circumference of the trunk, broad leaves, root header ratio and dry weight of the robust coffee plant. The plant's dry weight is correlated very strongly with the increment of the number of leaves, broad leaves and root shoot ratio. Plant dry weight correlated strongly with the increase in the circumference of the trunk and the increment of plant height.   Keywords: coconut water, seeds, robusta coffee
