Abstract

The fluctuations of the availability of water is a matter of in growth this licensing process for rice. The availability of the water sufficient is advantages for the growth of plants rice farming. The rice crop need the different volume for each phase the real sector growth reached. Water had a very important role at the time of the nymph formation and initiation panicles . This studied attempts to watchful over the influence of the waterworks frequency on the growth and production of rice fields with water. Design was used in this research was Random design a group ( a shelf ) non factorials consisting of 5 treatment and 3 preparation of test questions, Namely A = ( times inundated by persistently even rising up early ), B = the frequency of of waterworks 4 once over days, C = the frequency of of waterworks 8 once over days, D = 12 day once upon the irrigation system, and E = frequency irrigation 16 days once. Data was analyzed statistically each observation treatment, and when markedly dissimilar was continued by test said different real give an bnj ) the first 5 percent. Based on the research, with analysis design a rack non factorials, can be concluded that the use of frequency irrigation to optimize its growth and the production of in plants rice yield real impact to higher plants and heavy grain dry.

Abstract

The purpose of this study is to obtain a early-harvest rice mutant maturity, ideal height, number of tillers, and ideal height. The method was used in this study is the method of pedigree. Planting M2 was the first stage of selection to be carried out next by pedigree. Prospective mutants in M2 generation of irradiated cultivars of sijunjuang consist of; a) 2 genotypes of very mature candidate mutants (104 hss), b) 152 genotypes of maturing mutant candidates (110 hss - 120 hss), c) 18 genotypes of prospective mutants mature and have ideal high criteria, and d) 2 genotypes of mating candidates that are mature and have the ideal total number of tillers; e) 7 genotypes of prospective mutants with weight of dry harvest grain above average yield per hectare from the description of kutivar Sijunjuang ie 5.5 Tons/Ha. Mutant candidates in M2 generation resulting from irradiation Kuriak Kusuik consist of; a) 2 genotypes of very early genetic candidates (104 hss), b) 76 genotypes of mature candidates (113 hss -124 hss), c) 323 genotypes of moderate mutant candidates (126 hss -147 hss), d ) 123 genotypes of prospective mutants very mature and have ideal high criteria and e) 4 genotypes of prospective mutants mature with high and total number of ideal tillers, f) as many as 18 genotypes of prospective mutants who have weight of dry grain harvest above the average production per hectare of Kuriak Kusuik cultivar description and g) has one genotype of prospective mutants that have a early-harvest age and have an ideal agronomic character.

Abstract

Palm oil is one of the fastest growing commodities in the last two decades. Termites are one type of pest in oil palm plantations. This pest is a major pest of young oil palm plantations, especially re-planting in peat areas. The impact is very large, such as a decline is not production. These pests can be growth from seedlings to harvest. This research aims to know the types and characteristics termites in oil palm plantations Simpang Raya, Singingi Hilir, Riau February until June 2016. The method of this research was using descriptive method and field observations. Data were analyzed with descriptive assessment study and using a guidebook used to description pest. The sample were conducted by unload nests in any point sample, when the sample were done in the morning and to identify type termites can use a book. The result showed that the termites attacked in the corner kingdom is the type Coptotermes curvignathus and Macrotermes gilvus. Has often rise after the rainy season this to be supported by conditions of temperature that fits perfectly.

Abstract

The daro fruit is a plant peculiar to Dharmasraya, until now there is no information about the characteristic of such a plant. The purpose of this research is to invent and to characterize of the morphology of the daro at the District of Koto Baru Regency of Dharmasraya. This research is conducted under both surveys and interview methods then followed with the morphological inventory and characterization. There are found about 103 trees of daros. The descriptive result shows that the tree grows standing upright, woody, and the bark of the tree is rough with light brown and white spotted. The cross-section is round. The leaf is incomplete for it only has a stalk, and a blade of leaf with the dark green upper surface and smooth and light green lower surface, and the leaf spine is fish bone like. Both ends of leaf are conical. The fruit is round and the peel is light brown with dark brown spots. The fruit meat is white and thin. The seeds are dark brown and shiny with 1 cm diameter.

Abstract

The center of planting salak Sidimpuan in the district of West Angkola is in highlands, whereas the center of planting Sidimpuan Snake Fruit in South Angkola in the district is in lowland. Fruits of Sidimpuan Snake Fruit are originated from West Angkola, generally tastes sweeter compared with salak of South Angkola. Differences of altitude level from salak planting area is suspected to be one of the factors causing the different levels of sweetness and production salak Sidimpuan. This research was conducted in district of West Angkola and district of South Angkola with altitude of 600-700 m asl and 200-300 m asl, starting from December until January 2017. Analysis of salak sugar level was done at Agricultural Faculty Laboratory of Graha Nusantara University, Padang Sidimpuan. The method was used in this research is survey and purposive sampling. To determine the comparison of production and sugar content of Sidimpuan Snake Fruit in lowland and high plains were analyzed using an independent t-test. The results showed that the comparison of Sidimpuan Snake Fruit production in the plateau (1,231 kg per tree) was significantly different with the production of Salak Sidimpuan in the lowlands (0.991 kg per tree). The comparison of sugar content of Sidimpuan Snake Fruit in highland area (10,550%) was significantly different with sugar content of Sidimpuan Snake Fruit in lowland area (9,100%).
