Abstract

The aim of this study is to determine the way in which water management and rice cultivation techniques are carried out in tidal land. This study uses a survey method and interviews with rice farmers in Sanglar Village, Reteh Regency, Indragiri Hilir Regency. Farmers 'respondents were collected by means of targeted sampling based on the location of farmers' groups downstream, in the middle and upstream of the secondary channel. Each part of upstream, middle and downstream will be taken 2 farmer groups as samples then 8 farmers will be taken as survey respondents. So thatthe total respondents were 48 tidal rice farmers. The results of the research data are presented in the form of tables and images that are described descriptively. The management of water used in Sanglar Village is classified as simple water management, characterized by the condition of buildings that are still made of earth and there are no building meters and retention. The cultivation technique used in Sanglar Village is one of the traditional cultivation techniques. This can be seen from planting to harvesting, most farmers have not used Alsintan and agricultural innovations. The highest productivity is indicated by the downstream channel with 3.73 tons. Ha-1 is still relatively low due to simple water management and traditional breeding techniques that require improvement in water management and cultivation techniques.Keyword : Water Management, Rice Cultivation, Tidal Land

Abstract

Merremia peltata is a type of Invasive Allien Species (IAS) that belongs to one type of liana plants located in the tropics. Efforts to combat exgan for now are still very minimal because information about morphology and physiology of Merremia peltata is still lacking. The importance of this research is directed to develop an innovation in the control of exgan weeds by utilizing liquid smoke as a natural herbicide. This study aims to: (1) to find out the influence of liquid smoke as a natural herbicides in controlling the growth of Merremia peltata weeds; (2) to know the best dose of liquid smoke as a natural herbicide in controlling the growth of Merremia peltata. The study used the Complete Randomized Design (CRD) method which used five treatments and five repeats. Merremia peltata that has been grown for 14 days in 25 polybags 30x45 cm each polybag contains three Merremia peltata. After that spraying using grade 3 liquid smoke of various concentrations is carried out on the 15th day after planting. Spraying of grade 3 liquid smoke as much as 15 ml per polybag is carried out every two days until the 33rd day after planting. The data obtained was analyzed using fingerprint analysis test, if the real effect continued with Duncan's New Multiple Range Test (DNMRT) at a level of 5%. The data obtained and analyzed statistically using the SPSS application program. The results showed that the application of natural herbicides with grade 3 liquid smoke base material has an effect in suppressing the growth of Merremia peltata. Application of grade 3 liquid smoke with a dose of 15 ml / l is the most influential control and best in suppressing the growth of Merremia peltata as weeds Keywords : Merremia peltata, weed, liquid smoke, control, grade 3

Abstract

 1.2. The purpose of this research is to determine some potential lines to be continued with the preliminary yield trial. The Lines used obtained from selected F3 plants resulted from a cross between Grobogan and KM19 having large seed and early maturity. Thirteen genotypes, consisting of the 11 F6 lines and two parents namely Grobogan and KM19 were planted in the Experimental Station of the Faculty of Agriculture, University of Riau, Pekanbaru. Field experiments were established by using a randomized block design in a 3 m x 2 m plot with three replications. Plant materials were maintened according to standard cultivation techniques and spacing of 40 cm x 20 cm. The parameters observed included plant height, number of branches, age of flowering, age of harvest, number of filled per plant, number of seeds per plant, weight of seeds per plant, weight of 100 seeds, dry weight of plants, and yield per m2. The data were analyzed according to the Dunnet test at the 5% level by the SAS Program version 9.0. The results indicated wide variability between lines for seed number per plant, seed weight per plant, and seed yield per m2. Genetic component of variance was greater than 0 for the three characters with high heritability. There were detected several linesw having high yield potential; ie, GK19-3-12, GK19-3-27 and GK19-3-41 with greater number of filled pods, higher seeds weight per plant and seed weight per m2than Grobogan and KM19. Keywords : genetic variance,  heritability, yield potentials, yield components

Abstract

The objective of this research aims to determine phenotypic performance and variability of M1 generation of Dega 1 soybean variety after irradiated seed by gamma ray radiation and get suitable rate of the mutagen to obtain genetic variability. Irradiation by gamma ray to the seed of Dega 1was established in the Laboratory of Badan Tenaga Atom Nasional, Jakarta while phenotypic observation was conducted in the Experimental Garden, Faculty of Agriculture, University of Riau beginning on January until April 2018 by using a completely randomized design. The treatments wereG1(50 Gy), G2 (100 Gy), G3(150 Gy) and G4(200 Gy) gamma ray radiation and parental line as a control. The characters observed were growth habits, leaflet number, leaf shape, flower crown color and pod color. Result of the research showed that gamma ray irradiation to the seed caused some levels of mutation on qualitative characters including, the change in leaflets number, and leaf shape but not for flower color and pod color.  Irradiation seed by gamma ray  causedwide variability on leaf shape for all rates of irradiation with the coefficient of variation (CV) of ranging from 0.43 to 0.64. This inferred that the values of population variability of M1 resulted from seed irradiation was not similar in magnitude.Keywords:Soybean, qualitative characters, variability, gamma ray
