The optimum plot size is required at the time of experiment lay out to obtain the accuracy and reliability of the experimental result. In absence of uniformity trail, an alternative procedure is described to get the idea of optimum plot size. The process involves for determining the accurate estimate of soil heterogeneity coefficient followed by optimum plot size through the past experimental data of split plot design and the expression for the determination of soil heterogeneity has been derived and illustrated through several artificial and real data. The result indicated the considerable gain in efficiency to the tune of 19 and 22 per cent in some cases. This procedure leads to the saving of plot size from 20 per cent to 75 per cent.

<p>Perbanyakan karet (Hevea brasiliensis Muell. Agr.) dengan okulasi cokelat membutuhkan waktu yang lama dalam pembibitannya, sedangkan perbanyakan dengan okulasi hijau belum banyak dilakukan karena tingkat keberhasilan masih sangat rendah. Salah satu faktor yang diduga berpengaruh terhadap keberhasilan okulasi hijau adalah umur bibit batang bawah. Tujuan penelitian adalah mengetahui pengaruh perbedaan umur batang bawah terhadap persentase keberhasilan okulasi hijau pada tiga klon karet. Penelitian dilaksanakan di Kebun Percobaan (KP.) Pakuwon, Balai Penelitian Tanaman Industri dan Penyegar pada bulan Januari-Desember 2013. Penelitian menggunakan rancangan petak terbagi, tiga ulangan dan ukuran petak 25 pohon. Petak utama adalah jenis klon batang bawah, terdiri dari 3 klon, yaitu K1 = AVROS 2037, K2 = PB 260, dan K3 = GT 1. Anak petak adalah umur batang bawah terdiri dari 4 taraf, yaitu U1 = 4 bulan, U2 = 5 bulan, U3 = 6 bulan, U4 = 7 bulan. Okulasi dilakukan dengan cara membuka kulit batang bawah, kemudian entres dimasukkan ke dalam jendela sayatan hasil pembukaan. Pengikatan sambungan dilakukan dengan menggunakan plastik khusus dengan cara dililitkan dari bawah ke atas. Pengamatan dilakukan terhadap persentase keberhasilan okulasi hijau pada umur tiga minggu setelah okulasi (MSO). Hasil penelitian menunjukkan bahwa keberhasilan okulasi hijau pada tanaman karet dipengaruhi oleh umur batang bawah. Untuk Klon PB 260 dan GT 1, makin tua umur batang bawah sampai maksimum 7 bulan di polybag maka semakin meningkat persentase keberhasilan okulasi, sedangkan pada klon AVROS 2037 belum memperlihatkan perbedaan yang nyata.</p><p>Kata kunci: Hevea brasiliensis, umur batang bawah, klon, keberhasilan okulasi hijau</p><p>Propagation of rubber (Hevea brasiliensis Muell. Agr.) using brown budding need a long time in the nursery, whereas the propagation usinggreen Budding has not yet been done due to the success rate is still very low. One of the factorthat might influence the successfulness of green budding is rootstock age.. The purpose of this study was to determine the effect of different age of rootstock on the percentage of green budding success in three rubber clones. The experiment was conducted at the Pakuwon experimental station (ES), Indonesian Industrial and Beverage Crops Research Institute, from January-December 2013. The research was done using split plot design with three replications, and the plot size is 25 trees. The main plot was the type of clones used for rootstock that comprised of 3 clones: K1 = AVROS 2037, K2 = PB 260, and K3 = GT 1. Meanwhile, the subplots were rootstock age consists of 4 levels, namely: U1 = 4 months, U2 = 5 months, U3 = 6 months, U4 = 7 months. Observations were made on the percentage of green budding success at 3 weeks old after grafting . The results showed that the success of the green budding on the rubber plants is influenced by the age of rootstock. The use of rootstock up to 7 months old in polybag in PB 260 dan GT 1 clones would increase the percentage of grafting success, whereas AVROS 2037 clone did not show any significant different.</p><p> </p>

Abstract Four 80 acre commercial sunflower fields were divided into 40 acre strips 0.5 mile in length. Furadan at a rate of 1.0 lb (AI)/acre was applied with the seed at planting time in 1 strip and a similar strip was left untreated. Fields were bordered with 32 treated rows Asana XL was applied by air in equal width strips perpendicular to the direction of planting. An early treatment using Asana XL in 1.0 gpa total was applied at the 4-6 leal plant stage. A late treatment of Asana XL was applied at bud stage; both applications were made to 1 strip, and one strip remained untreated. Treatments were randomized and arranged in a split plot design. Individual plot size was approximately 10 acres. Yields were obtained by taking two 3 ft X 20 ft subsamples per 10 acre plot from the center of each 10 acres. Means were compared using LSD.

<p><strong>The effect of living post and pepper vines primings on the pepper yield</strong></p><p>To obtain good yield of pepper, farmers fequently apply various treatments to their crops, including pruning of the pepper vines and or their living post. Studies on the aspects of the pruning ae however very limited. Therefore a ield experiment was conducted to investigate the effects of pruning of pepper vines and their living post on the pepper yield. The experiment was carried out at Sukamulya Research Station, Sukabumi. A split plot design with three rcplicaties was used. The main plot was the pruning of living post, and the sub plot was the pruning of pepper vines Plot size was 20 plants per plol wilh spacing of 2.5 m x 2.5 m Results showed that there was signiicant interaction between the pruning of living post and pepper vines. The pruning of living post may be carried out either 3 times (October, January and April) or twice (October and January) a year. However. If the pruning of the living post is carried out 3 times per year, Ihe vine would be pruned once a year or not at all. On the other hand, if the pruning of living post is carried out twice a year, the pepper vines would be pruned 6 times a year.</p>

Electron microscopic methods have been applied increasingly during the past fifteen years, to problems in structural molecular biology. Used in conjunction with physical chemical methods and/or Fourier methods of analysis, they constitute powerful tools for determining sizes, shapes and modes of aggregation of biopolymers with molecular weights greater than 50, 000. However, the application of the e.m. to the determination of very fine structure approaching the limit of instrumental resolving power in biological systems has not been productive, due to various difficulties such as the destructive effects of dehydration, damage to the specimen by the electron beam, and lack of adequate and specific contrast. One of the most satisfactory methods for contrasting individual macromolecules involves the deposition of heavy metal vapor upon the specimen. We have investigated this process, and present here what we believe to be the more important considerations for optimizing it. Results of the application of these methods to several biological systems including muscle proteins, fibrinogen, ribosomes and chromatin will be discussed.

In order to measure the concentration of arsenic atoms in nanometer regions of arsenic doped silicon, the HOLZ analysis is carried out underthe exact [011] zone axis observation. In previous papers, it is revealed that the position of two bright lines in the outer SOLZ structures on the[011] zone axis is little influenced by the crystal thickness and the background intensity caused by inelastic scattering electrons, but is sensitive to the concentration of As atoms substitutbnal for Siatomic site.As the result, it becomes possible to determine the concentration of electrically activated As atoms in silicon within an observed area by means of the simple fitting between experimental result and dynamical simulatioan. In the present work, in order to investigate the distribution of electrically activated As in silicon, the outer HOLZ analysis is applied using a nanometer sized probe of TEM equipped with a FEG.Czodiralsld-gown<100>orientated p-type Si wafers with a resistivity of 10 Ώ cm are used for the experiments.TheAs+ implantation is performed at a dose of 5.0X1015cm-2at 25keV.

<p><em>Penelitian ini bertujuan untuk mempelajari pengaruh sistem tanam alur dan pemberian jenis pupuk terhadap pertumbuhan dan produksi kacang tanah (Arachis hypogaea L.). Penelitian dilaksanakan di KP Leuwikopo IPB Dramaga, Bogor pada bulan Februari - Juni 2013. Percobaan menggunakan rancangan petak terbagi (Split Plot Design) dengan perlakuan terdiri dari dua faktor, yaitu sistem tanam alur sebagai petak utama dan jenis pupuk sebagai anak petak. Hasil penelitian menunjukkan bahwa perlakuan sistem tanam alur meningkatkan daya hasil pada produktivitas biji kering, produktivitas polong kering, dan bobot kering biji per tanaman lebih baik dibandingkan sistem tanam konvensional. Hal tersebut ditunjukkan dengan perlakuan sistem tanam alur yang memiliki produktivitas 2.93 ton/ha polong kering, sedangkan sistem tanam konvensional sebesar 2.55 ton/ha polong kering. Sistem budidaya kacang tanah pada sistem tanam alur dapat meningkatkan efisiensi tanaman dalam memanfaatkan unsur hara yang telah diberikan baik pupuk organik maupun anorganik, sehingga pertumbuhan dan hasil tanaman kacang tanah menjadi lebih baik. Pemberian jenis pupuk kandang ayam + Dolomit + NPK memberikan respon terhadap pertumbuhan dan  daya hasil rata-rata tanaman yang lebih baik dibandingkan jenis pupuk lainnya.</em></p>
