Abstract Plots, 3.5 X 12 ft, arranged in a split-plot design with each chem-ical treatment replicated 3 times, and each of 4 genotypes replicated twice within each treatment strip, were planted at Moscow, ID on 20 Aug, 1995 at 9.5 lb/acre using a small-plot, cone seeder. Capture 2 EC and methyl parathion 4 E were applied 5 Jun with a CO2-pressurized tractor-mounted sprayer equipped with 80° fan nozzles on an 8.3-ft boom that delivered 20 gpa at 30 psi. At the time of treatment, wind conditions were calm (<5 mph), and ambient air tem-perature was above 60°F. Plots were sampled for adult CSW 2 before treatment and 2 d after treatment by dislodging them into a 5-gal plastic bucket with a beat of a hand at each end of a plot. To determine the number of exit holes, 10 pods were removed from 10 racemes from each side of each plot on 17 and 18 Jul. Plots were harvested 15 Aug with a small-plot combine (4.6 ft header). All data were subjected to analysis of variance.

ABSTRACT Objectives: The present study aimed to investigate the effect of staining solutions on microhardness and shade changes of a nanofilled resin composite, which had been previously in contact with bleaching agents. Materials and Methods: A total of 135 disk-shaped specimens (10 mm × 2 mm) were fabricated with a nanofilled resin (Filtek Supreme) and photocured with a Light Emission Diode (LED) unit and then allocated into three groups to be bleached with 10% or 16% carbamide peroxide (CP) bleaching agents or a 35% hydrogen peroxide (HP) product. Following bleaching, specimens within each group were subdivided into three groups to be immersed in coffee, red wine or distilled water. Microhardness and color were monitored at baseline, after bleaching and after staining. Results: Analysis of variance for split-plot design showed lower microhardness values when the composite had been in contact with HP (P < 0.0001). The specimens immersed in red wine and coffee provided lower microhardness values than those immersed in distilled water, regardless of the bleaching agent to which the composites were previously exposed. Kruskal Wallis and Dunn tests demonstrated that the composite was lighter after bleaching with a 35% HP agent (P < 0.0500). Conclusion: The composite was darker as a result of being immersed either in red wine or coffee, regardless of the bleaching agent.

Abstract Ten insecticide treatments were evaluated for control of CSPW in winter canola at the Bledsoe Research Farm near Griffin, GA. Canola was planted on 14 Oct in 7 inch rows with a grain drill. Treatments were applied at 50% bloom on 7 Apr and 7 d later at full bloom using a CO2-powered backpack sprayer (20 psi) equipped with 003 flatfan nozzles which delivered 27 gal/acre. Plots measured 30 × 30 ft and were arranged in a RCBD with 4 replications. CSPW adults were sampled at 0 (pretreatment), 3, 7, 10 and 14 DAT by taking 6 sweeps per plot with a 15-inch diam sweep-net. The percentage of CSPW infested pods was measured by inspecting 200 pods/plot on 25 May. The center 2 drill passes were harvested on 11 Jun with a small-plot combine. Grain weight and test weight were measured, and yields were adjusted to 8% moisture content.

This paper deals with the planning and modeling of a split-plot experiment to improve novel gas sensing materials based on Perovskite, a nano-structured, semi-conductor material that is sensitive to changes in the concentration of hazardous gas in the ambient air. The study addresses both applied and theoretical issues. More precisely, it focuses on (i) the detection of harmful gases, e.g., NO 2 and CO, which have a great impact on industrial applications as well as a significantly harmful impact on human health; (ii) the planning and modeling of a split-plot design for the two target gases by applying a dual-response modeling approach in which two models, e.g., location and dispersion models, are estimated; and (iii) a robust process optimization conducted in the final modeling step for each target gas and for each gas sensing material, conditioned to the minimization of the working temperature. The dual-response modeling allows us to achieve satisfactory estimates for the process variables and, at the same time, good diagnostic valuations. Optimal solutions are obtained for each gas sensing material while also improving the results achieved from previous studies.

Despite the presence of both fixed and random effects in most agricultural experiments, many crop researchers have continued use of the conventional analysis of variance (ANOVA) model or general linear model (GLM) that provides a correct analysis only if all the effects are fixed. Ignoring or mistreating random effects may have inadvertently led to inappropriate analyses and thus to dubious conclusions appearing in the scientific literature. The objective of this paper is to provide a tutorial account of the mixed-model methodology and its applications to the analysis of agricultural experiments. The description and discussion on ANOVA vs. mixed-effect models center on the use of PROC GLM vs. PROC MIXED of the SAS® System. This paper points out the need for mixed-model analysis, describes and discusses key new features and properties of mixed-model analysis that would facilitate the understanding and use of PROC MIXED. Additionally, it analyzes and interprets three examples: comparison between two samples, and analyses of randomized complete design and split-plot design. Appendices include SAS code and theory underlying mixed-model analysis which will help gain hands-on experiences and ensure correct interpretation of SAS outputs by PROC MIXED. Such a comparative assessment of GLM vs. MIXED procedures will help to underscore the key advantages of PROC MIXED and to convince GLM users to make a true transition towards the increased and appropriate use of PROC MIXED in agricultural experiments.Key words: Analysis of variance, fixed vs. random effects, general linear models, inference spaces, mixed models, randomized complete block design, split-plot design

Nepenthes adrianii (Kantong Semar) merupakan tanaman endemik khas Gunung Slamet, termasuk dalam Convention on International Trade of Endangered Species (CITES) terdapat apendiks I (Tahun 2003) dan II yaitu tanaman ini tergolong hampir punah dan langka. Mengingat besarnya potensi yang dimiliki tanaman ini, maka perlu adanya upaya konservasi untuk mengembangkan dan melestarikannya. Penerapan bioteknologi kultur jaringan atau kultur in vitro merupakan solusi yang tepat untuk melestarikan dan mengembangkan tanaman ini. Kultur in-vitro digunakan untuk multiplikasi tunas dan pembentukan plantlet.Penelitian ini bertujuan untuk: 1) mempelajari pengaruh interaksi BAP dan NAA pada multiplikasi tunas: 2)  menentukan konsentrasi interaksi BAP dan NAA yang paling baik untuk memacu multiplikasi tunas; 3) mempelajari pengaruh bahan penyangga eksplan dan NAA pada pembentukan plantlet kantong semar (Nepenthes adrianii); dan 4) menentukan jenis bahan penyangga eksplan dan konsentrasi zat pengatur tumbuh NAA yang paling baik untuk memacu pembentukan plantlet kantong semar  (Nepenthes adrianii).Metode yang digunakan adalah metode eksperimental, penelitian ini terdiri atas 2 tahap yaitu multiplikasi tunas dan pembentukan plantlet. Tujuan penelitian  pada tahap multiplikasi tunas adalah untuk perbanyakan tunas dan tujuan penelitian pada tahap pembentukan plantlet adalah untuk mendapatkan tanaman kecil yang sejati. Tahap Multiplikasi Tunas menggunakan Rancangan Acak Lengkap (RAL) pola faktorial dengan 2 faktor. Faktor I adalah konsentrasi BAP yang terdiri dari 4 taraf yaitu 0 µM, 5 µM, 10 µM, dan 15 µM, Faktor II  konsentrasi NAA yang terdiri dari 4 taraf yaitu yaitu 0 µM, 0,5 µM, 1 µM, dan 1,5 µM. Tahap Pembentukan Plantlet menggunakan Rancangan Petak Terpisah (Split Plot Design) sebagai petak utama adalah bahan penyangga eskplan (P) yaitu:  agar dan jembatan kertas saring, sedangkan sebagai anak petak adalah konsentrasi NAA yang terdiri dari 4 taraf yaitu 0 µM, 5 µM, 10 µM, dan 15 µM. Parameter yang diukur dalam multiplikasi tunas yaitu waktu muncul tunas, waktu muncul daun, waktu muncul akar, jumlah tunas, jumlah daun dan jumlah akar. Parameter yang diukur dalam pembentukan plantlet yaitu jumlah tunas, jumlah daun, jumlah akar, daun terpanjang, akar terpanjang dan tinggi tanaman. Data yang diperoleh dianalisis menggunakan Analisis Ragam (Anova : Analysis of Variance) dengan  tingkat kepercayaan 95%. Pengujian F menunjukan hasil sangat nyata kemudian dilanjutkan dengan uji Beda Nyata Jujur (BNJ) untuk mengetahui perbedaan antar perlakuan.Hasil penelitian menunjukan bahwa pada tahap multiplikasi tunas terbaik didapat pada perlakuan interaksi BAP 10 mM dan NAA 0,5 mM. Tahap Pembentukan plantlet terbaik di dapat pada perlakuan interaksi bahan penyangga jembatan kertas saring dengan zat pengatur tumbuh NAA 5 mM dan 10 mM.
