Abstract

The research was conducted in the Faculty of Agriculture and Animal Science State University of Sultan Syarif Kasim Riau. This research aimed to determine best ameliorant which can increase the chemical content of peat soil such as pH, N, P, K and decrease C, C/N. The research used random sampling method, there are: without ameliorant, chicken manure fertilizer, compost of oil palm empty fruits bunches, rice husk ash, and bunch ash. The results showed that give rice husk ash and dolomite can increase some nutrient content of peat. Based on result of the research rice husk ash can increase P  from lowest to highest criteria. Giving dolomite increase best pH value, from sour to neutral.

Abstract

Plant intercropping that interplanted with young palm oil plantation indicated that there was change on ecosystem balance which resulted diversity alteration of insect as bio indicator area. The objective of the research was to obtain information on diversity of insect related to its intercropping system interplanted with young palm oil plantation. The research was conducted from December 2015 to February 2016 at privately-owned oil palm plantation, Kualu district, Kampar regency, Riau province. Descriptive methods by range survey on corn monoculture, soybean monoculture, bera, between corn and soybean intercropping in young palm oil area were used as experimental methods. Insect sampling was conducted by using pitfall trap, sweeping net and hand collection at 16 research units. The result showed that there were ten different insect ordo consisted of 50 families in all intercropping system sampled in this study. Diversity index (H’) reached as high as 3.07 with the best average (E=0.07) that was observed in soybean monoculture. Corn - soybean intercropping posessed the highest point of insect dominance (0.34), which is mean that there was only one kind of insect dominated on the community. The utilization of soybean monoculture system interplanted in young palm oil plantation is best to be used as a reference of ecological indicator on environment utilization, due to the reason that the existence of pest is balanced by the predator.

Abstract

Palm oil (Elaeis guineensis Jacq.) is a plantation crop which is quite important in Indonesia because it accounts for foreign exchange and create employment that is high enough. Palm oil empty fruit bunches (EFB) is estimated at 20% of fresh fruit bunches ( FFB ) and coco in (cocopeat) are very much in Riau as raw material for fertilizer / compost. Subsoil ultisol a bottom layer of soil with sufficient depth within therefore very potential as a medium of palm oil nursery but has a low fertility signified by the nature of physics, chemistry and biology poor. Organic matter such as EFB compost and cocopeat can improve physical, chemical and biological subsoil ultisol. The research aimed to study the effect of EFB compost , cocopeat and a mixture of both the subsoil ultisol medium on the growth of palm oil seedlings in pre nursery. The study was conducted at the experimental station of Agriculture Faculty of the University of Riau from June to August , 2015. Research conducted an experiment using a completely randomized design (CRD) consisting of 6 treatments (K0 : without treatment , K1 : 100 g cocopeat , K2 : 100 g compost EFB , K3 : 50 g compost EFB + 50 g cocopeat , K4 : 75 g of compost EFB + 25 g cocopeat and K5 : 25 g compost cocopeat EFB + 75 g per plant) each repeated 4 times. The results showed treament EFB compost 50 g and cocopeat 50 g produce in the growth palm oil seedlings better than the other treatments on medium subsoil ultisol in pre nursery.

Abstract

This research was conducted from January until May 2015 at Pangkalan Panduk Village Kerumutan Subdistrict of Pelalawan Regency of Riau Province. The research aimed to determine the differences value pH, C-organik, KTK, N-total, P-total, and K-total at 0-50 cm, samples from forest peatlands, oil palm plantations at the age of 7 years and industrial forest plantations Acacia crassicarpa at the age of 6 years. The results showed an increase in pH by 0.03 % from peat forests into oil palm plantations and increased pH also occurs in peat forests into industrial forest by 0.96 %; an increase KTK of peat forests into oil palm plantations amounted to 22.62 mg/100g and peat forests into plantations amounting to 113.87 mg/100g; P-total increased from peat forests into oil palm plantations amounted to 22.62 mg/100g and peat forests into plantations also increased by 12.74 mg/100g; K-total increased from peat forests into oil palm plantations of 2.73 mg/100g and peat forests into plantations by also increased by 12.31 mg/100g. For C-organic chemical character changes occur perbedan where a decline of peat forests into oil palm plantations amounted to 11.15 % and an increase of C- organic peat forests into plantations by 0.05 % . Neither the N - total increased from peat forests into oil palm plantations of 0.51 % and a decline of peat forests into plantations by 0.31 %. We conclude changes in the chemical character of peat for all parameters measure were influenced by the changes in secondary forest peatland into oil palm plantations age of 7 years and plantation forests Acacia crassicarpa age 6 years.

Abstract

At this time the oportunity increasing soybean production still open through optimize the fulfill of the nutrient of plants. Phosphorus is one of element nutrient essentiality macro those as very important to growth and development of plants. The existence it in land abundance, but the concentration P who are get reserve by plant is very low. At acid land P bunching aluminum (AI) and iron (Fe) meanwhile in land Alkhalin P bounded calsium (Ca). The increasing efesiency of supply fosfat at plant can effort with exploit microorganism soluble phosphate group. Test potential solubility P by BPF isolated from peat soil Biosphere Reserve Giam Siak Kecil Bukit Batu, Riau. Test was conducted and taken in semi-quantitative which able to dissolve Ca3 (PO4) 2, FePo4 and phosphate rock. However adaptability and potential dilution BPF origin peat soils of Riau indigenus inoculated soybean in mineral soil until now unknown. This research was conducted in order to determine the effect of inoculation BPF indigenus Riau toward growth and yield of soybean. The study was conducted in factorial experiment using completely randomized design (RAL Factorial), as the first factor is soil treatment consisting of two levels ie: T0: soil without sterilization, T1: sterilized soil. The second factor is the provision isolates BPF which consists of 4 levels, namely: B0: without inoculation, B1: 2 isolates BPF (BB_UB6 and BB_K9), B2: 3 isolates BPF (BB_UB6, BB_K9 and BB_K2), B3: 4 isolates BPF (BB_UB6, BB_K9, BB_K2, and BB_HS13). The results showed soil sterilization decrease the number of primary branch becomes 5.67 and 1.49 g dry weight of the plant. The fastest time of harvest occurs in plants without inoculation of sterile soil that is 78.78. The highest weight of 100 seeds produced by the plant without inoculation of sterile soil that is 13.17 g.

Abstract

Orchids are a very popular ornamental plants, but orchids have a very slow vegetative growth, thus requiring special treatment in the grown.To  spur grow than development can be used through tissue culture techniques of multiplication. But the success of the technique of tissue culture is inseparable with give a substance on the plant growth regulator. This study aims to determine the growth  an influence  D.phalaenopsis Fitzg orchids of giving a gaint swith IBA administration and Kinetin according to in vitro  and as well as to obtain a concentration combination of  IBA and Kinetin on the best orchid D.Phalaenops is Fitzg explants.  Base don’t he results of the study indicate that the combination of IBA and Kinetin concentration giving a influence percentage of live explants,   number of shoots and number of roots orchid D. phalaenopsis Fitzg explants.Combination treatment of IBA 1.0 ppm and 0.1ppm Kinetin is a combination of the best treatment to produce a number of shoots orchids.The giving of IBA 0.5ppm in the medium without the addition of kinetin concentration can increase the number of roots of the orchid D.phalaenopsis Fitzg.
