Abstract

      The objectives of this study were to determine the components of variances, heritability and selections responce of several traits in a soybean population applied by liquid foliar fertilizer (LFF). A field  experiment was conducted  in the Faculty of Agriculture Experiment Station, University of Riau from February to May 2018 using a split plot design with three replications. Three rates of LFF concentrations applied to plant leaves; ie, no LFF, 2 g.l-1 and 4 g.l-1 were a signed as main plot and eight varieties were assigned as subplot. Seed of every cultivar was panted in a plot of 3 m long and 2 m wide with planting space of 40 cm x 20 cm on February 2018. In the control treatment, inorganic fertilizer was applied according to recommended rate; ie, 25 kg N, 30 kg P2O5, and 30 kg K2O per ha, respectively while for plots applied by LFF, the fertilizer was only applied by one half of recommended rate. Characters observed were plant height, flowering date, number of primary branches, harvest date, number of filled pods per plant, number of seeds per plant, seed weight per plant, seed filling rate, effective seed filling periods, grain yield and hervest index. Data were analyzed by analysis of varians and further tested by least significant different at 5% level. The component of variance and heritability were estimated by the procedure of Hallauer et al. (2004). The result indicated wide variability among varieties for all characters while LFF affected only on  number of primary brunches, plant high, flowering date, grain yield and harvest index. The value of genetic variance was significant for all traits and heritability value was different from zero for all characters. Predicted response to selection was quite high for  number of filled pods per plant and  number of seeds per plant but quite low for other characters. The result indicated that all characters could be used as selection criteria in a plant breeding program. However, number of seeds per plant  and number of filled pods per plant as selection criteria were potential to speed up in reaching plant breeding objective.  Keywords : varians component, heritability, black soybean, selection response

Abstract

An experiment has been designed to investigate the impact of Phosphorous (P) fertilizer on seed quaaliti during seed development of several Soybean (Glycine max L. Merrill) cultivars. The field experiment was carried at University of Riau Agriculture Experiment Station using a complete randomized block design with three replicates. Soybean cultivars such as Willis, Malabar, Kipas Putih and line KM-19-BE were planted in three rates of P fertilizer; ie P0 = 0 kg P2O5 as a control, P1 = 25 kg P2O5, and P2 = 50 kg P2O5 per hektare. Seed quality including seed viability and seed vigor was observed at 10 days interval from 20 to 50 days after anthesis (DAA). It was found that seed quality was very low at early stage of seed development and tent to reach its maximum value as seed matured. Addition of P fertilizer to the plant increased some components of seed quality at early stage of seed development until 40 DAA. The values of seed viability and seed vigor were higher in seed harvested from plant fertilized by P than control, mainly for seed obtained at early seed development. This results indicated that P fertilizer application would improve seed quality especially of seed harvested at early seed development of some soybean cultivars.

Abstract

Kang kong (Ipomeareptans Poir) is popular and tasty vegetable mainly grown in tropical asia. In this experiment, we tried to apply rice hay trichocompost to look at if the trichocompost could be utilized for fertilizer in cultivating kang kong.  The research was conducted at the Agriculture Experiment Station, University of Riau from June to July 2013. Five rates of trichocompost was applied and arranged in a randomized block design with four replications. Two seed of kang kong were planted each planting hill with planting space of 20 cm x 30 cm in. Plot size was 1,0 m in length and 1,5 m wide.Observations were made for plant height, shoot-root ratio, number of leaves per plant, leaf canopy area, and fresh weight per plant. The results showed that rice hay trichokompost improved plant growth, mainly in plant height, number of leaves and increased production as represented by vegetable fresh weight. However,leaf canopy area and shoot-root ratio showed no significant differences among the rate of trichokompost. The research suggested that rice hay trichocompost may be applied to the rate of 12 tons / ha in order to obtain better growth and higher fresh vegetable yield.

Abstract

This research was intended to determine the possibility of manure application to replace inorganig fertilizer on crop growth and seed yield of soybean. A field experiment was conducted at the experimental farm of the Faculty of Agriculture University of Riau, Pekanbaru in 2013. The experiment was arranged in randomized block designwith seven treatments and three replications. The treatments were recommended rate of inorganic fertilizers (Urea 55 kg/hectare, TSP 55 kg/hectare and KCl 73 kg/hectare), chicken manure at rates of 2 tons, 3 tons and 4 tons per hectare; cow manure at rates of 10 tons, 12 tons and 14 tones per hectare. Seed of G19BE genotype was planted in a plot of 3m x 2 m with the planting space of 40 cm x 20 cm. All rates of animal manure were apllied 10 days before planting while fertilizer was applied at planting date. The results showed that inorganic fertilizer and any kinds of manure affected vegetative growth of soybean at the same manners. Application of cow and chiken  manure, in general, yielded more filled pods, more number of seeds per plant, seed weight per plant and seed yield m -2 than inorganic fertilizer application. Chicken manure ate of 4 ton hectare yielded greater seed weight per m² compared to cow manure or artificial fertilizer. This result suggests that organic manure may be utilized to replace inorganic fertilizer in soybean cultivation.           Keywords: Chicken  manure, cow manure, soybean

Abstract

The objective of this researchis to determine the response of soybean (Glycine max (L) Merril) on application of ethepon under two planting spaces and to determine the concentration of ethepon application for a specific planting space.A field experiment was conducted by using split plot design, in which four levels of ethepon concentration ie; 100 ppm, 200 ppm, 300 ppm and control were assigned to main plots and two levels of planting spaces ie; 40 cm x 15 cm and   40 cm x 20 cm were assigned as subplot. Parameters observed were plant height 35 days after planting, number of primary branches, internode length of the main stem, plant growth rate, leaf area index, days to flowering, grain yield per plot , and 100-seed weight. The data were analyzed by analysis of variance andfurther investigated by least significant difference atp = 0.05. The result shown thatethepon application tented to shorten plant height and internodes height, lessen the number of primary branches, decreased leaf area and leaf area index, accelerate flowering dates and decreased grain yield per plot, but not for 100-seed weight. The implication drawn from this research was that application of ethepon could not be recommended for soybean.   Keywords: soybean, ethepon, plant spacing

Abstract

One of main problems in increasing soybean production is the attack of pests such as soybean  pod borer  (Etiella zinckenella Treitschke). The objectives of this research was to determine the variance components and heritability of various characters associated with resistance to soybean  pod borer. A field experiment was established by randomized complete block design where six cultivars of soybean including Gema, Grobogan, Kaba, Willis, lines KM 19 and KM 25 are planted in plots of  2.5 m in length and 2 m in wide. The experiment  was conducted at the Center for Integrated Seed production at Pasir Pengaraian, Riau  Province. The parameters observed were number of larva per plant, percentage of damage pods per plant, percentage of damage seeds per plant, number of pods per plant, number of seeds per plant, yield per m2, weight of 100 seeds dry and additional observations. The data were analyzed by using analysis of variance and then the components of genetic and phenotypic variance and heritability were calculated. The results showed that all parameters were relatively narrow genetic variation. Phenotypic variation was narrow for number of larva per plant, percentage of attacked pods and  weight of 100 seed dry, and considered wide for the percentage of seeds damage, number of filled pods, number of seeds per plant, and yield per m2.  Broad sense heritability values were high for percentage of attacked pods, the percentage of seeds damage, number of filled pods, number of seeds per plant, weight of 100 seed, and  very low for number of larvae per plant and yield per m2. Genotype Willis and KM 19 are two potential cultivars to be chosen as a parent to develop resistant cultivars to soybean pod borer. Keywords: soybean, variance components, heritability, genotype, resistant to soybean pod borer

Abstract

This study attempted  to determine the change of  morphological and  physiological traits of fruit palm oil during the fruit development until harvest. Forty eight fruit bunchs which antheses at the same day were selected at random from oil palm trees in the Experimental Station of PT Panca Surya Garden at Kubang Raya, Kampar. The fruit bunches were hand pollinated at 18 April 2015 and each was covered by pollination bag. Starting at 30 days after pollination (DAP), 3 fruits bunches were harvested at 15 day interval until fruits were ready to harvest. The change of morphological and physiological traits were observed  such as fresh weight, dry weight, fruit moisture content, thickness of mesocarp, fruit diameter, fruit volume and fruit color. The data analysis were performed by simple regression assingned day after pollination as independent variable and the traits observed as dependent variables.  The results indicated that change in morphological traits such as mesocarp thickness, fruit volume, fruit diameter occurred in similar pattern. Rapid change of  the value appeared from 30 to 75 DAP, followed by very slow increased from 75 to 150 DAP and finally the  rapid increase from 150 to 180 DAP. The pattern of dry weight and fresh weight change was similar, in which progressive increase was occurred  from 30 to 180 DAP then followed by decreased until 187 DAP. Moisture concentration of the fruit increased slightly from 30 to 45 DAP than decreased progressively from 45 to 187 DAP. Fruit color changed from dark purple to red purple and finally at harvest the color change to yellow red.

Abstract

Growth regulators such as gibberellic acid (GA3) is expected to remove and prevent barriers imposed by geneticand enviromnental effect on plant growth and supposed to increase crop production. In this study, we intended todetermine the effect of GA3 on agronomic and yield components of four soybean varieties. The field experiment wasarranged in a split plot design with three replications. Three levels of GA3 concentrations such as 0 ppm as control, 125ppm and 250 ppm were assigned as main plot and sprayed over the plant at 21 days after planting. Four varietiesincluding Kaba, Grobogan, Wilis and Anjasmoro were used as subplots and the seed of each variety was sown in a plotsize of 3,2 m x 3 m. Several growth parameters and yield components were observed from each plot. The results showedthat GA3 effect was inconsistent for the four varieties. It appeared from this study that GA3 did not affect leaf area index,time to flower, time to harvest, number of filled pods per plant, seed number per plant, and harvest index for all varieties.Application of GA3 at levels of 125 and 250 ppm increased crop growth rate, plant height and internode length of mainstem in all genotypes except Anjasmoro. The main impact of different levels of GA 3 application was an increase in seedweight per plant and grain yield. The highest grain yield was achieved with application of 125 ppm GA 3 for Kaba andGrobogan and of 250 ppm for Wilis and Anjasmoro. This imply that application of GA 3 to soybeans genotypes has to betaken care with cautiously according to the genotypes.

Abstract

The objective of this research was to determine phenotypic variability of mung bean M2 and M3 Mutant populations resulted from gamma ray irradiation. The Field experiment was conducted by using a completely randomized design in which three populations including M2, M3 and the parent (M0) were planted in 2017. Each population was planted in a plot of 3 m x 2 m with planting space of 30 cm x 20 cm to obtain 100 individual plant per plot. Every population was repeated 5 times so to get 500 plants per population. Observations were collected on all individuals in the population including plant height, number of stem internodes, length of internode, number of primary branches, age of flowering plants, date of harvest, length of pods, number of filled pods, number of seeds per pod, number of seeds per plant, weight of seeds per plants, and weights of 100 seeds. The results showed that gamma ray irradiation produced mung bean plants with a similar date of harvest. It could be seen from mean values ​​which were not significantly different, the values ​​of diversity, and range were almost equal which indicates the diversity of M2, M3 and M0 populations was relatively similar to the control. M2 and M3 generation of mung bean have large and high quality seeds weighing more than 6.5 g/100 seeds. The homogeneity of variance (HOV) analysis showed that variance of all population of all parameters observed were not homogeny except for plant height, number of stem internode and weight of 100 seeds.
