Abstract

Hoya diversifolia Blume (Asclepiadaceae) is one of Indonesian’s native plants that has potential to be developedas ornamental plant. The short flowering period in one year, however, is a big problem in developing Hoya as anornamental plant. The objective of this research was to determine the flower developmental phases and to study thecorrelation of endogenous sugar content with floral induction of H. diversifolia Bl. Morphological and anatomicalobservations showed that floral development of H. diversifolia Bl. consisted of 6 phases i.e. induction, early initiation,late initiation, differentiation, flower maturity, and anthesis. Total sugars and sucrose content were not significantlydifferent between inductive and non-inductive buds, while the amount of reducing sugar were significantly higher in theinductive buds (7.40 mg g-1 fresh weight) compared to non-inductive buds (4.14 mg g-1 fresh weight).Key words: Asclepiadaceae, flowering plant, Indonesian native ornamental plant

Abstract

The objective of this study was to determine the impact of phosphorous (P) fertilizer on soybean seed dry weight andseed quality during seed development. Four genotypes of soybean ie; G1=Willis, G2=Malabar, G3=KM-19 BE, andG4=Kipas Putih were planted in an experiment arranged in a completely randomized block design consisting of threerates of P fertilizer including P0=0 kg P2O5/ha, P1=25 kg P2O5/ha, P2=50 kg P2O5/ha were applied to every genotype.Beginning 20 days after flowering, fresh weight and dry weight of the seed were collected every five days while seedquality components were observed every teen days from each plot. Fresh and dry weight were plotted to the graphs andanalysis of variance were performed to seed quality. The results showed that the seed development was slow until 20 daysafter flowering (DAF) but both tend to steadily increase then until around 40 DAF and then started to levelling off until50 DAF. Seed viability and seed vigor remained low until 30 HSP and achieved reached maximum values at around 40to 50 DAF. Applying P fertilizer at a rate of 50 kg P2O5 per ha accelerated grain filling and increased the germination rateof the seed harvested at beginning 20 DAF to 40 DAF on every genotype. This result implied that genotypes respondeddifferently to fertilizer P as indicated by differences in seed weight and seed quality during seed development.Keywords : seed development, viability, vigor, soybean

Abstract

To get good productivity, the management of dryland in acid soil require specific technologies that made farmingmore effective, efficient and sustainable. Riau province has potential for crop agriculture, with the majority of plantationcrops and apart of food crops such as upland rice, soy, peanuts and corn.. The purpose of this study is to study severalvarieties of soybean response to three levels of inputs in dry land areas Tandun Riau province. The experimental designused is a randomized block design with two factors. The first factor is the level of input that consists of a). A low input (50kg.ha-1 urea, 50 kg.ha-1 SP-36, 50 kg.ha-1 KCl); b) Medium input (75 kg.ha-1 urea, 100 kg.ha-1 SP-36, 75 kg.ha-1 KCl and500 kg.ha-1 lime); c) High input (75 kg.ha-1 urea, 100 kg.ha-1 SP-36, 100 kg.ha-1 KCl and 1000 kg.ha-1 lime. Factor II issoybean varieties that consist of a). Anjasmoro, b). Agromulyo, c). Tanggamus, d). Kaba and e). Wilis. Observationsincluded plant height, number of branches, number of empty pods per plant, number of pods per plant and pod yield. Thestudy shows the input level and variety affect the number of branches, number of empty pods, number of pods and soybeanyields. Anjasmoro varieties with high input gives the highest yield (1.5 t.ha-1) when compared to other treatmentcombinations. While the lowest yield was obtained at Kaba and Wilis varieties with low input, ie, 0.8 t.ha-1.Keywords: varieties, soybeans, input level, sour dry land

Abstract

Isolation and utilization of peat soil mycorrhizae have been started, yet for local peat soils of Riau has not beenwidely studied. The odjective of this study were to determine the types of mycorrhizae on oil palm plant stands on peatland in several districts in Riau. Peat soil sampling in several Bengkalis districts (Bantan Middle Village, DistrictBantan), Kampar (Village Rimbo Panjang, District Tambang), Pelalawan (Sungai Ara Village, District Sungai Ara) andSiak (Temusai Village, District Bunga Raya). The research was conducted in the laboratory with soil sampling inaccordance with the purposes of research and analysis in the laboratory according to the method of each parameter.This study had found that 2 genus Acaulospora spores and Glomus. The genus consists of Acaulospora, Acaulosporatuberculata, Acaulospora foveata and Glomus genus consists of Glomus diaphanum, Glomus etunicatum and Glomussp.1. but the types of spores are more dominant in the 4th District is the kind of spores Glomus sp.1.Keywords : isolation, identification, peatsoil, mycorrhizae, palm oil

Abstract

Chili production in Indonesia is less than optimal due to many factors, such as plant disease and pest attack. Plantdisease and pest attack can be controlled with increased resistance of plants through plant breeding, genetic engineering,as well as by inducing plant resistance using microbes such as Arbuscular Mycorrhizae Fungi (AMF). This researchaims to study the effect of the potential of the growth and resistance of chili crops, AMF exploration needs to be doneand propagated in two types of medium sand to facilitate application in chili. Stages of research are the exploration,identification and propagation of AMF and test preparation of chili crops. AMF inoculum propagation results withsand mediums are used in research as much as 50 g, 100 g, 150 g and 200 g per polybag. AMF inoculum was added tothe planting hole with time transplanting. This research used a completely randomized design with three replications.The purpose of this study was to determine the response of the growth and yield of chili crops on the application of FMAin sand medium. Variables measured include crop height, number of leaves, number of flowers, number of fruits, fruitweight and percentage of fruit maturity. Based on the results of this study concluded that the multiplication of AMFspores in the medium sand gives good results. The number of spores on the mountain sand is higher than the sea sand. Allvariables of growth and yield of chili crops treated with AMF showed good results and significantly different than thecontrol. The author recommends to use a formulation FMA medium sand mountain with 200g dose because it producesthe highest fruit weight .Keywords : Arbuskular Mycorrhiza Fungi, sand medium, chilli crops.

Abstract

An experiment to study the growth and yield components the efficiency of N, P and K fertilizers for paddy rice in theprogram of prosperous Riau food operation (OPRM) and to define the exactly recommended fertilizer in Kampar district hasbeen conducted from July to November 2011. The research was conducted using Randomized Block Design (RBD) with 6treatments and 4 replications. The further test has been conducted using DNMRT 5 %. The treatments consisted of : A0=withoutfertilizer; A1=7.5 g Urea, 6 g TSP and 3 g KCl per plot; A2=15 g Urea, 12 g TSP and 9 g KCl per plot; A3=22.5 g Urea, 18 gTSP and 15 g KCl per plot (dosage of fertilizers recommended in the program of prosperous Riau food operation in Kampardistrict); A4=30 g Urea, 24 g TSP and 21 g KCl per plot; and A5=45 g Urea, 30 g TSP and 15 g KCl/plot (dosage of fertilizersrecommended in the program of prosperous Riau food operation in Riau). The results showed that effect of N, P and K fertilizersfor paddy rice was significant in increasing the number of productive tillers, the percentage of grain filled and grain yield,whereas the parameters of 100-grains weight, and the efficiency of grains was not significant. The application of N, P and Kfertilizers 45 g Urea, 30 g TSP, and 15 g KCl per plot (150 kg.ha-1 Urea, 100 kg.ha-1 TSP, and 50 kg.ha-1 KCl) which was thedosage of fertilizers recommended in the program of prosperous Riau food operation at Riau increased grain yield better thanthe other dosage. If converted to hectar, the yield was equals to 4,07 tons.ha-1.Whereas, the highest of grain yield efficiency wasat dosage of 7.5 g Urea, 6 g TSP and 3 g KCl per plot (25 kg.ha-1 Urea, 20 kg.ha-1 TSP and 10 kg.ha-1 KCl). The recomendeduse of fertilizers for paddy rice planted with PB-42 variety in Kampar District was suggested at a dosage of 150 kg.ha-1 Urea,100 kg.ha-1 TSP and 50 kg.ha-1 KCl.Keyword: recommendation, N, P, K fertilizers, paddy- rice, efficiency, OPRM program
