Abstract

One effort to improve chemical properties of Dystrudepts is to use an organic mulch Mucuna bracteata (MB). The study aims to determine the effect of application of organic mulch MB on soil chemical properties and plant root growth of oil palm. The research was conducted in experimental station and the soil laboratory, Faculty of Agriculture, Riau University, Pekanbaru. The research was conducted in September 2014 – February 2015. The research was non factorial experiment that arrangge by Randomized Complete Design (RAL) with treatment control, M1 (15 kg of organic mulch/plant), M2 (30 kg organic mulch/plant), and M3 (45 kg organic mulch/plant). The results showed that application of an organic mulch MB with more increasing dose resulted more increasing of pH value, C-organic, N-total, KTK, KB and root growth.   Keywords: organic mulch, Dystrudepts, Mucuna bracteata

Abstract

The objective of this research was to study the effect of liquid waste biogas in the topsoil and subsoil media, and to determine  theappropriate dosage for the growth of palm oil (Elaeis guineensis Jacq.) plant seeds in main nursery.The research was done in a Completely Randomized Designwith two factors and was replicated three times. The first factor is the liquid waste biogas and the second factor is difference medium layer. Data were analyzed by analysis of variance (ANOVA) and further tested using Duncan`s New Multiple Range Test (DNMRT) at the level of 5%. The parameters observed were the increment of seeds height (cm), leaf number (midrib), tuber diameter (cm), ratio of the root crown (g), dry weight of seedling (g) and quality index of palm oil plant seeds (g).Combination the application of liquid waste biogas with top soil and sub soil were not significantly to all parameters. The combination liquid waste biogas dose of 300 ml/plant with top soil media tends to gave the best results. The application of liquid waste biogas showed the real impact on the leaf number accretion,tuber diameter, dry weight of seedlings and ratio of the root with crown.The application of liquid waste biogas dose of 300 ml/plant showed the best growth increment to oil palm seedlings varieties of topaz aged 3-6 month. Used of top soil media showed the good effect on dry weight of plant seed oil palm age 6 months. Key word: liquid waste biogas, sub soil, top soil and oil palm seedlings.

Abstract

This study aims to look at the effect of sawdustash and guano fertilizer on the growth and production of pepper plants in peatland as well as to get appropriate dose of sawdust ash and manure guano. This research was conducted at the experimental peat garden, Faculty of Agriculture, University of Riau, RimboPanjang, Kampar. The research lasted for five months, from December 2013 until May 2014. The experiments was conducted using factorial randomized block design consisting of two factors and three repetition. The first factor is the sawdustash 10 ton / ha (4 kg/plot), 20 tons / ha (8 kg/plot), 30 t / ha (12 kg/plot) and the second factor is the guano fertilizer, 100 kg / ha (40 gram/plot), 200 kg / ha (80 gram/plot), 300 kg / ha (120 gram/plot). Parameters measured were plant height, days to flowering, fruit length, fruit diameter, harvesting age, fresh fruit weight and fruit weight per plot. The data obtained were statistically analyzed using analysis of variance followed by Duncan's multiple range test at 5%. The result show that the best dose for enhancing chili growth and production is 20 ton/ha (8 kg/plot) sawdust ash and 300 kg/ha (120 gram/plot) guano fertilizer. The best treatment parameters: flowering age, harvesting age, fruit length, fruit diameter, and fresh fruit weight, fruit weight per plot.   Keywords: chili,sawdust ash, guanofertilizer and peatland

Abstract

Chili (Capsicum annum L.) is one of horticultural commodities has significant economic value, however land in Riau that used for this farming have low fertility as peatland. Therefore the use of organic fertilizer that low complete material is indispensable in improving the productivity of chili, one of the organic fertilizer that is maize rubbish Tricho-compost. This research aimed to determine the effect of multiple dosage application maize rubbish Tricho-compost in enhancing the growth and productivity of chili plants on peatsoil medium. The data were analyzed statistically using analysis of variance followed by Duncan’s New Multiple Range Test (DNMRT) at 5% level and regression analysis  Orthogonal. The result showed that differences in the growth and productivity of chili of several dosage of the treatment, that the provision Tricho-compost with a dosage 15-20 ton ha-1 was found to give highest circle stem, fruit weight per plant and stimulated harvesting time. Tricho-compost with a dosage 20-30 ton ha-1 was found give highest plant height, volume of root, fruit length and stimulated flowering time. Keyword : Chili, corn waste Tricho-compost, peatsoil

Abstract

The objective of this study was to know the growth and  yield of some varieties of sorghum  which were given several dose phosphorus fertilizer.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 study,s  arranged experimentally Randomized Block Design with two factors namely varieties of sorghum and phosphorus fertilizer with three block. First factor are  Kawali, Numbu, Pahat dan Mandau. Second factor are SP-36 45 kg/ha, SP-36 90 kg/ha dan  SP-36 135 kg/ha. Parameters observed were plant height, trunk base diameter, the number of leaves, number of segments per plant, flowering age, age of harvest,  panicle lenght, weight seeds per panicle, weight 1000 seeds and yield per m2. Data were analyzed statistically using ANOVA and followed by Duncan’s New Multiple Range Test at level of 5%.The results showed that the provision of phosphorus fertilizer was significantly on various varieties who researched. The provision dose phosphorus fertilizer 90 kg/ha and 135 kg/ha significantly increase higher plants on varieties of Numbu. The different dose of phosphorus fertilizer 45 kg/ha and 90 kg/ha significantly increase the number of segments on varieties of Kawali and Numbu. The provision dose phosphorus fertilizer 45 kg/ha – 135 kg/ha significantly speed up the age of harvest on varieties of Pahat and Numbu. The provision dose phosphorus fertilizer 90  kg/ha has given highest yield/m2 on varieties of Pahat (8,5 ton/ha) and Mandau (8,7 ton/ha). The provision dose of phosphorus fertilizer 135  kg/ha given highest yield/m2 on varieties of Kawali (9,0 ton/ha). The increase dose phosphorus fertilizer 45 kg/ha – 90 kg/ha given highest yield on varieties of Pahat and Mandau, while increase dose phosphorus fertilizer until 135 kg/ha given highest yield on varieties of Kawali and Numbu. Keywords : Sorghum bicolor (l.) Moench, phosphorus fertilizer, yield component.
