Abstract

The objective of this research was to determine the growth and fiber content of five kenaf varieties and find out the variety that able to give the best fiber yield. This research was conducted in the agricultural experimental unit, Agriculture Faculty, Riau University from May until September 2015. The study arranged experimentally using Randomized Block Design (RBD) consist of 5 treatments and 4 replications. Varieties those used are Karang Ploso 6, Karang Ploso 9, Karang Ploso 11, Karang Ploso 12 and Karang Ploso 14.The data were examined by analysis of variance and means separation by Honestly Significant Difference (HSD) test at 5%. The parameters those observed were flowering age, harvesting age, plant height, stem diameter, plant fresh weight, stem fresh weight, fiber dry weight, and ratio of stem fiber. Varieties of  Karang Ploso 6, Karang Ploso 9, Karang Ploso 12 dan Karang Ploso 14 has same plant height potential. Higher plant will produce longer fibers.   Keywords : kenaf, varieties, growth.

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

The objective of this research was to determine the effect of TKKS compost, P2O5 and TKKS interaction with the P2O5 as well as to get the best dose for growth and production of red rice. This research was conducted in the agricultural experimental unit, Agriculture Faculty, Riau University, Bina Widya Street, sub-district of Simpang Baru, district of Tampan, Pekanbaru. This research was conducted for six months from  May until October 2015. The study arranged experimentally using Randomized Block Design (RBD) factorial. The first factor was TKKS with 4 levels consisting of: 2,5 ton/ha, 5 ton/ha, 7,5 ton/ha and 10 tons/ha and second factor was P2O5 with 4 levels consisting of: 15,525 kg/ha  (TSP33,75 kg/ ha), 31,05 kg/ha (TSP 67,5 kg/ ha), 46,575 kg/ha (TSP 101,25 kg/ha and 62,1 kg/ha (TSP 135 kg/ha). The parameters those observed were plant height, number of maximum tillers,  number of productive tillers, the panicle emergence age, panicle length, number of grains per panicle, filled grain percentage, dry milled grain weight/m2, and weight of 1000 grains milled rice.Analysis of variance and HSD 5% was used for data analysis. The results of research suggested that an increase in all variable observations with increasing dose of treatment. Dry milled grain weight/m2 positively correlated with all the variable observations except for the observation panicle age youth are correlated negatively. TKKS 7.5 ton/ ha and P2O5 46,575 kg/ha treatment can be used as combination to increase growth and yield of red rice.   Keywords: red rice, TKKS, P2O5

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
