Abstract

Fruit flies is major pest on chilli. Controlling this pest can be used of atractan. The experiment to get species of fruit flies and the most fixed oil type both as atractan fruit flies pest at chilli plant (Capsicum annum L.). The experiment was conducted at Laboratory of Plant Pest and experimental garden University of Riau Pekanbaru, from January until April 2013. The experiment used a Randomized Block Design (RBD) with 4 treatments and 6 replications. The treatments are trap with fixed oil four. Atractan are sweet flag (Acorus calamus), sweet basil (Ocidum minimum), celery (Apium gravoelens) and lemongrass scanted (Andropogon nardus). Results of the research showed catch two fruit flies species. That species are B. dorsalis and B. umbrosa. Sweet basil is best atractan. That can catch fruit flies with averagely 26,83 numbers. All fruit flies which gotten are male fruit flies. Female fruit flies at most gotten of lemongrass scanted with averagely 0,33 number. Fixed oil of sweet basil constitutes at longest atractan its active term with averagely 4,66 days.

Abstract

Animal Science Faculty of Universitas Islam Negeri Sultan Syarif Kasim Riau. The objective of the research was to know the interaction between plant density and several varieties on plant growth and yield of cowpea. The experimental design was Randomized Complete Block design arranged in factorial between 2 plant densities (250.000 and 500.000 plants/ha) and 3 varieties of cowpea (KT6, KT7 and KT8) with 2 replications. The data were collected for plant height, plant dry weight, leaf area index, number and weight of nodules at 30 days after planting, number of pods/plant, number of seeds/plant, weight of 100 seeds and seed yield. Result of the research showed that increased plant density from 250.000 to 500.000 plants/ha increased leaf area index from 1,47 to 2,73 and increased seed yield from 230,2 to 271,9 g/plot. The other plant growth and yield components were not affected by different plant density. Variety affected plant dry weight, number and weight of nodules and yield components, but did not affect seed yield.

Abstract

The research was conducted on February to agustus 2013 in the Tambang and Tapung Districk, Kampar Regency, Riau Province. The purpose of this research was to observe changes of soil chemical properties from secondary peat forests wich was converted to oil palm plantations at 6th and 26th years. This study is conducture by observation and survey at 50 cm and 100 cm of depth. Chemical analysis of the soil included pH, total-N, P-bray, C-organic, Cation Exchange Capacity (CEC), and Basa Cations (K, Ca, Mg and Na). Results of the analysis showed converted of peat land to oil palm plantation cause an increase in pH (1.19%), reduction in C-organic (17.94%), N-total (62.54%), Mg-dd (62.54%) and Na-dd (0.13%). Increase occurred oil palm at 6th years for CEC by (11.87%), P-bray (3.35%), K-dd (0.05%) and Ca-dd (13.89%). Decline occurred oil palm at 26th years for the by CEC by (3.35%), P-bray (10.91%), K-dd (0.09%) and Ca-dd (63.2%).

Abstract

The objective of this research was to observ physiological process on soybean with diifferent soil moisture content and gibberelic acid concentration. The research was conducted at Experimental Field of KP4 Gadjah Mada University in Kalitirto, Yogyakarta. The research using split-plot design 5x3 factorial with 3 replications. The major plot was soil moisture content, which was arranged by randomized complete block design, consisted of 5 soil moisture content levels: 100, 80, 60, 40, and 20% field capacity. The Sub-plot was the concentration of gibberelic acid with 3 levels: 0, 100, and 200 ppm. The results showed that declining soil moisture content 60% soil capacity decreased transpiration rate 25,5%, leaf area and plant growth rate 2-6 WAP 11.25%. Interaction of soil moisture content 80% field capacity and 100 ppm gibberelic acid concentration increased plant dry weight 6 WAP.

Abstract

This Research aimed to select wheat genotypes which potential to be developed in a high rainfall area. It was conducted at September 2012 to January 2013 in Alahan Panjang, Solok Regency, West Sumatera. Seventeen wheat genotypes were planted at Alahan Panjang, Solok, West Sumatera from September 2012 – January 2013, including local varieties (Nias, Selayar, Dewata). It used random design block with 3 replications and 10 samples each block. If genotypes were significant according to test f then continued by test duncan on standard 5 %. Observed variables were amount of spikelet per spike, amount grain of spikelet, amount of floret per spike, spikelet length and width, grain length and width, amount of full grain, amount of unfull grain and a thousand grain weight. The result showed that UAGDM 13 had a good amount of spikelet per spike. All genotypes had high amount of floret per spike except UAGDM16. A good spikelet length was belonged to all genotypes except UAGDM11 and UAGDM13. Grain length and width were not significant among all genotypes. Three genotypes which had a high amount of full grain were UAGDM5, UAGDM6 and UAGDM17. Genotype UAGDM1 was the best of a thousand grain weight.

Abstract

Karakterisasi dan evaluasi beberapa genotipe sorgum koleksi dari fakultas pertanian Universitas Andalas telah dilakukan mulai Agustus 2012 sampai dengan Desember 2012 di Sukarami Kabupaten Solok. Tujuan penelitian ini adalah untuk melihat keragaman fenotipe sorgum di daerah dataran tinggi. Genotipe yang di uji adalah L1, L2, L3, L4 dan L5. Metoda yang digunakan adalah menanam genotipe sorgum dalam petakan berukuran 2x3 m, dengan sampel yang diamati masing-masing genotipe adalah 6 sampel. Kegiatan perekaman data dilakukan terhadap keragaan karakteristik tanaman sorgum secara kualitatif. Pada masa vegetatif pengamatan seperti (Bentuk Ujung Daun, Kehadiran Lidah daun, Permukaan Daun, Warna Batang Kecambah), dan pada masa generatif pengamatan berupa (warna biji, bentuk biji, ukuran biji, warna sekam dan sifat sekam). Pertumbuhan genotipe sorgum yang diamati pada masa vegetatif, tidak menunjukkan perbedaan yang signifikan secara morfologi antara genotipe L1, L2, L3, L4, dan L5. Morfologi daun seperti ujung daun, bentuk lidah daun, keadaan permukan daun, pertulangan daun kelima genotipe sorgum memiliki sifat yang seragam. Perbedaan genotipe sorgum dapat dikenali lebih jelas pada fase generatif dibandingkan fase vegetatif.
