Abstract

Adequate supply of nutrient by fertilizer are generally believed to improve soybean yield especially when it is grown in suboptimal soil condition.  In this study we grew a soybean variety and fertized them with N and K fertilizer to determine the response of the variety to the time of N application and the rate of K fertilizer. A field experiment was conducted in Agriculture Experiment Station near Pekanbaru by using a randomized completely block design with 3 replications. The rate of potassium fertilizer were 25 kg K2O per ha, 50 kg K2O per ha and 75 kg K2O per ha while the time of N application were 25 kg N per ha at planting date, 25 kg N per ha at 30 days after planting and 25 kg N per ha at planting and add another 25 kg N per ha at 30 days after planting. Seed were planted with a rate of 30 cm by 20 cm in a plot of 3 m length and 2 m wide in 2017.  Parameters observed were plant height, number of main branches, plant growth rate, leaf area index, flowering date, harvest date, number of filled pods per plant, seed weight per plant, seed yield per m2, weight of 100 seeds and harvest index. The results showed that application of N fertilizer affected leaf area index, number of filled pods, seed weight per plant, and grain yield per m2, however, the rate of K fertilizer only affected plant growth rate and leaf area index but did not for others characters. The treatment combinations indicated the significant effect on number of main branches and seed yield per m2, where the application of N 25 kg per ha at planting followed at the same rate at 30 days after planting and adding by 50 kg per ha K2O gave greater number of main baranches and more grain yield per m2. Keywords :  nitrogen aplication, potassium fertilizer, yield components, growth rate

Abstract

To increase soybean productivity required some efforts as one is to develop new high yielding variety or improving existing varieties. To obtain and improved a variety, one need to obtain a population with high genetic variability in order to ease the selection of new suitable cultivars. In this study, we usedinduce mutations using chemical mutagen, ie, Ethyl Methane Sulphonate (EMS),to increase the variability. This research had been conducted in the Plant Breeding Laboratory and Experimental Garden of the Riau University. Seed of Dega-1 Variety were soaked by solution of EMS in buffer phosphate within several concentration ie, 200 ppm, 300 ppm, 400 ppm, 500 ppm, 600 ppm and 700 ppm. Seed then were washed with aquadest to cleand remaining EMS solution and than planted together by initial Dega-1 as control in the field experiment using a completely randomized design (RAL) withfour replications. Parameters observed were plant height, number of internodesthe age of flowering, age of harvest, number of pods per plant, number of filled podsper plant, number of seeds per plant, seed weight per plant, number ofseeds per pod and type of growth, flower color, and pod color. Population variancewere calculated byMicrosoft Excel software. The homogeneity ofthe variance was tested with HOV in accordance tothe procedures of theLevene’s test. The results showed that the induction of mutations with 200 ppm of EMSincreased genetic variance in M1 generation compare toDega 1 variety for most quantitative character, including plant height, number of pods per plant, number of filled podsper plant, number of seeds per plant, and seed weight per plant. Induce the mutation by EMS solution, on the other hand, didn’t change all qualitative character.                                                    Keywords:Induced Mutation, Ethyl Methane Sulphonate, Population Variance, Quantitative Traits, Qualitative Traits

Abstract

Recently, fertilizer is considered as necessary cultural practices that could increase soybean production. So, this experiment was intended to determine the role of phosphorous fertilized on seed development and seed quality of several soybean varieties. Three varieties of soybean were grown in a plot of 3.2 by 3 m with planting density 40 x 15 cm. Ten days after planting, the plant were fertilized by mixing 53 kg Urea, 53 kg KCl and TSP as treatment applied. To obtained seed water concentration and seed dry weight, 300 flowers were randomly chosen from each plot, and 10 pods developed from the flowers were harvested every 5 days beginning from 15 days after anthesis (DAA) to 50 DAA. In addition to seed development, we observed dry matter accumulation rate, effective filling period, and seed quality at harvest. The change in seed moisture content was relatively fast from 15 DAA to about 45 DAA, then slightly slow until harvest time. Seed dry weight was very small until 20 DAA and contribute only 5 to 7% of its maximum dry weight. The linear increase in seed dry weight occurred from 20 DAA until 45 DAA, then tent to slow down before reaching physiological maturity. Application of P fertilizer increased KPBK and shortened WPE on Wilis and Gema but did not impact both traits on Gema. Grain yield of Kaba and Wilis was higher when fertilized by 25 kg P2O5 per ha, and tent to decline if fertilized by 50 kg P2O5 per ha.   Key Words : seed water content, seed dry weight, P fertilizer, seed development

Abstract

The objective of this research were to estimate genetic parameters such as variability, heritability, general combining ability (GCA), and specific combining ability (SCA),  of various agronomic traits in chili population through diallel cross. The research was arranged in a randomized complete block design in which 15 hybrids genotypes created by half diallel cross were evaluated with three replications. Seedlings of twenty eight days old was transplanted to a plot of 1 m x 5 m with planting space of 50 x 50 cm. Ten samples were chosen from each plot to obtain  plant height, height of stem dichotomous, weight per fruit, fruit length, fruit rind thickness, fruit diameter and fruit weight per plant. Data analyses were performed by analyses of variance and then translated to genetic parameters following the Griffing’s methods model IV. The results indicated that the value of GCA and SCA were significant for several characters but not for others. Due to its suitable GCA value, one genotype such as C5 may be selected as one parent to improve agronomic characters such as hastening days to flower and harvest,  increased stem diameter,  thick fruit pulp, fruit diameter, weight per fruit, and fruit weight per plant. Genotypes C120xC5 and C111xC19 may be utilized to improve stem diameter, thick fruit pulp, fruit diameter, weight per fruit, and fruit weight per plant. Heritability were significant for stem height,  dichotomous, stem diameter, fruit length, fruit flesh thickness, fruit diameter, total number of fruits per plant, and fruit weight per plant. Fruit rind thickness, fruit diameter, weight per fruit, and total number of fruits per plant was positively correlated to total fruit weight per plant.   Keywords  : Chili breeding, variability, heritability, combining ability

Abstract

Application of ethepon on soybean grown under densely population is expected to enhance plant growth and increase assimilate translocation to seed. Ethrel 40 PGR is chemical compound containing ethepon,  when it is in plant organ would be converted to ethylene and may accelerate flowering. This study aims to determine the effect of ethepon on soybean crop production under two different planting spaces. 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 plot and two levels of planting spaces ie; 40 cm x 15 cm and 40 cm x 20 cm were assigned as subplot. Traits observed were plant height, days to flower, days to harvest, filled pod numbers per plant, seeds number per plant, grain yield m² and 100-seed weight. The results showed that applicqation of ethepon shorten plant height, accelerate day to flowering faster but delay harvesting time at planting space of 40 cm x 15 cm and 40 cm x 20 cm. Yield components such as number of filled pods per plant and grain yiel per unit area were lower due to application of ethepon for both planting spaces.  The implication drawn from this research was that application of ethepon could not be recommended for soybean. Keywords: soybean, ethepon, planting spaces and production.
