Abstract

The soybean population of F4 strain descended from a cross between Grobogan varieties with KM19 and KM25 lines aims to observe the selection progress of several lines selected from the F3 population in the Faculty of Agriculture Experimental Garden, Riau University. The experimental design in the field used a randomized block design with 4 replications, the treatment consisted of 20 different soybean genotypes and 3 elders, thus there were 72 experimental plots measuring 300 cm x 100 cm, with a spacing of 20 cm x 30 cm. The parameters observed in this study were plant height, number of branches, age of flowering, age of harvest, seeds per pod, seeds per plant. seed weight per plant, weight 100 seeds, total pods, pith pods, yield per m2 and harvest index. Harvest age has a high heritability value, while the parameters of plant height, total pods, pod pods, number of seeds per plant, weight of seeds per plant, flowering age have moderate heritability values which means inheritance of these parameters in the next generation is not too large. The number of branches, seeds per pod, weight of 100 seeds and harvest index, has a low heritability value. The largest selection response value is the yield character per m2 that is equal to 46.04%, which means that each selection cycle using the yield criteria per m2 will change the middle value of 46.04%. Next there will be a change in the middle value of 33.47% in the number of seeds per plant, followed by a change in the middle value of 4.10% at the age of harvest, then a change in the mean value of the pods of 10.32%, followed by a change in the mean value seeds per plant is 33.47%, and the change in the mean value of the total number of pods is 10.75% if selected with criteria for the number of seeds per plant, age of harvest, number of pods in a row, and number of seeds per plant in a row. Keywords: Soybean, variability, selection, heritability,

Abstract

The expansion of the use of peat was not wise, causing the rate of peat destruction to be very fast. Peatlands in Riau have a large enough potential to be planted with various types of forest plants. Efforts are needed to achieve optimal plant growth on peat soils. Trichoderma sp. as Tricho-Compost, it was hoped that it can spur growth and improve the quality of Arenga pinnata plants. The purpose of this study was to determine the effect of Tricho-Compost application on the growth of Arrenga pinnata seedlings on peat media and to determine the best dosage of Tricho-Compost on Arenga pinnata seedling growth on peat media. The research was conducted using a completely randomized design (CRD) consisting of 4 treatments with 5 replications in order to obtain 20 experimental units.The compost of compost at several levels of concentration, namely: D0 = Without Tricho-Compost (Control) application, D1 = 25% Tricho application -Compost + 75% peat soil, D2 = Application 50% Tricho-Compost + 50% peat soil, D3 = Application 75% Tricho-Compost + 25% peat soil. The data obtained from the research results were statistically analyzed using Analysis of Variance (ANOVA) and further analyzed using Duncan's New Multiple Range Test (DNMRT) at the 5% level. The application of Tricho-Compost fertilizer has an effect on the growth of Arrenga pinnata seedlings. The application dose of Tricho-compost D2 fertilizer (application of 50% tricho-compost + 50% peat) shows the best treatment to increase the growth of Arenga pinnata seedlings in peat medium showed of a percent live yield as 96%, height increase as 17.25 cm and a top-root ratio as 3.71.Keywords : Arenga pinnata, Tricho-Kompos, growth

Abstract

The aim of this research was to get better yields of the true shallot (Allium ascalonicum L.) seed of Tuk Tuk variety on land that had been given plastic mulch and sprayed with coconut water. The research was carried out under the experimental garden shading net of the Faculty of Agriculture, Riau University, Pekanbaru, from July to October 2019, in split plot design experiment of simple random pattern with 3 replications. The main plot is a type of plastic mulch (M), consisting of: m1 = no mulch, m2 = silver black mulch, and m3 = silver mulch. The subplots was concentration of coconut water (K) as follows: k0 = 0%, k1 = 25%, k2 = 50%, and k3 = 75%. Variables observed were clump height, number of leaves per tuber, number of leaves per clump, tuber weight per clump, number of tubers per clump, tuber diameter, tuber height, weight of fresh tubers per plot and weight of dry tubers per plot. The observational data were analyzed of variance and Duncan New Multiple Range Test (DNMRT) at the 5% level. The results showed that no interaction between the type of mulch and the concentration of coconut water on the growth and production components of Tuk Tuk shallot seedlings. The growth components of the clump height and the number of leaves per clump, as well as the production components of tuber diameter and tuber height of the Tuk Tuk variety of shallots seedling is better if the plants are on land with silver mulch. The growth and production of the Tuk Tuk shallots seedlings  is not optimal because of weather disturbances and the shading net environment does not meet the growing requirements.Keywords: True Shallot Seed, mulch, coconut water
