<p><em>Seed coated</em> merupakan teknologi pelapisan benih dengan bahan tertentu untuk mempertahankan mutu benih dan membuat bentuk benih lebih teratur. Prosesing benih kapas saat ini masih menggunakan bahan kimia seperti asam sulfat (<em>seed delinted</em>) untuk menghilangkan kabu-kabu (<em>linter</em>) yang masih menempel pada biji setelah proses pemisahan serat dan biji. <em>Seed delinted</em> memungkinkan terjadinya kerusakan kulit hingga lembaga biji dan dapat menimbulkan masalah lingkungan dari limbah yang dihasilkan dalam proses tersebut. Penelitian ini bertujuan untuk menguji pengaruh perlakuan benih pada tiga jenis varietas terhadap viabilitas benih kapas. Penelitian ini menggunakan Rancangan Faktorial dalam RAK. Faktor Pertama terdiri atas beberapa perlakuan benih yaitu benih berkabu, benih <em>delinted</em>,<em> coated</em> dengan tapioka dan kaolin serta <em>coated </em>dengan<em> arabic gum</em>. Sedangkan, faktor kedua terdiri atas varietas kapas yaitu Kanesia 10, Kanesia 18 dan Kanesia 19. Hasil penelitian menunjukkan bahwa interaksi antara perlakuan benih dengan varietas kapas berpengaruh nyata untuk parameter panjang radikula dan menghasilkan koefesien keragaman mencapai 9.85%. Perlakuan benih <em>coated</em> dengan bahan <em>arabic gum</em> menunjukkan hasil yang terbaik untuk semua parameter pengamatan. Sedangkan, varietas Kanesia 10 menunjukkan persentase keserempakan tumbuh, persentase daya berkecambah, dan persentase potensi tumbuh maksimum terbaik masing-masing 92.25%, 96.25%, dan 98.00%. Perlakuan benih dengan teknologi <em>seed coated</em> menggunakan <em>arabic gum</em> pada Varietas Kanesia 10 dapat menunjukkan persentase viabilitas benih kapas terbaik.</p><p> </p><p><strong>Effect of Seed Coating on the Seeds Viability of Three Cotton Varieties ( Gossypium hirsutum L.) </strong></p><p><br />Seed coating technology with certain materials is objected to maintain seed quality and to make seed shapes more regular. Currently, cotton seeds processing is using chemicals such as sulfuric acid (acid seed delinted) to remove the linter which is still attached to the seeds after the separation of fibers and seeds. Acid seed delinting could causing damage on the seed skin as well as to the seed embryo and also cause environmental problems from the waste produced in the process. Seed coated technology has the prospect to be applied in the process of cotton seeding, so the process becomes environmentally friendly. This study aims to evaluate the effect of seed coating treatment on three cotton varieties on the seed viability. This study uses Randomized Block Design Factorial. The first factor consisted of four seed treatments namely fuzzy seed (control), seed delinted, seed coated with tapioca and kaolin and seed coated with arabic gum. The second factor were cotton varieties namely Kanesia 10, Kanesia 18, and Kanesia 19. The results showed that the interaction between seed treatments with cotton varieties significantly affected the radicular length parameters and produced a coefficient of varians 9.85%. Seed coated with arabic gum showed the best results for all observation parameters. Kanesia 10 showed the best of growing simultaneity, germination, and the potential maximum growth by 92%, 96%, and 98%, recpectively. The cotton cotton seed coated with arabic gum is prospective to be applied in the cotton seeding process as an alternative to the acid delinting technique that is not environmentally friendly. </p>

Nesse contexto, o objetivo deste trabalho foi avaliar os impactos da irrigação suplementar do algodoeiro, sem e com adubação química com NPK, e simulando-se as condições de umidade do solo baseada em uma série histórica de dados de precipitação dos últimos 30 anos para a região do Baixo Jaguaribe-CE, considerando-se cenários normais, seca e seca severa. A pesquisa foi desenvolvida no município de Russas – CE, em uma área vizinha à lagoa de estabilização da CAGECE. O ensaio foi instalado em delineamento em blocos ao acaso, com arranjo dos tratamentos em parcelas subsubdivididas, com quatro repetições. Os resultados mostram impactos de cenários hídricos e da suplementação sobre a maioria das variáveis de crescimento das plantas de algodoeiro. A irrigação suplementar com águas residuárias incrementa a produção de biomassa e o vigor das plantas de algodão durante a fase inicial de desenvolvimento, independente da presença ou ausência da adubação com NPK. Esses efeitos foram significativos especialmente nos cenários de seca e seca severa.   Palavras-chave: Gossypium hirsutum L, reuso de água, Irrigação.     ARAUJO, A. F. B.; LACERDA, C.

SUPPLEMENTAL IRRIGATION OF COTTON WITH TREATED WASTEWATER: BIOMETRIC ANALYSIS AND BIOMASS PRODUCTION     2 ABSTRACT   The use of treated wastewater in stabilization ponds for supplementary irrigation emerges as a strategy to increase agricultural production sustainably during the rainy season, eliminating, at least partially, the losses associated with summer. In this context, this work evaluated the impacts of supplementary cotton irrigation, without and with chemical fertilization with NPK, on soil moisture conditions based on a historical series of precipitation data for the last 30 years for the region of Baixo Jaguaribe-CE, considering normal scenarios, drought and severe drought. The research was conducted in the municipality of Russas - CE, in an area adjacent to the CAGECE stabilization pond. The trial was installed in a randomized block design, with the treatments arranged in sub-divided plots, with four replications. The results show impacts of water scenarios and supplementation on most growth variables of cotton plants. Supplementary irrigation with wastewater increases the production of biomass and the vigor of cotton plants during the initial stage of development, regardless of the presence or absence of NPK fertilization. These effects were significant, especially in drought and severe drought scenarios.   Keywords: Gossypium hirsutum L, wastewater, irrigation.

Seed coating using biological pesticides such as clove oil and citronella oil, was expected to have the ability to control seed-borne pathogens on rice. The aim of the research was to determine the effectiveness of seed coating using clove oil and lemon grass oil against seed-borne fungi and bacteria on rice seed variety “Hipa 8” during storage. The experiment was conducted in Cimanggis, from February to September 2012, using completely randomized design with single factor, consisting of four levels: (1) clove oil 1% + chitosan 3%; (2) lemon grass oil 2% + carboxymethyl-cellulose 1%; (3) Synthetic pesticide (streptomycin sulphate 0.04% + benomyl 0.1%) + arabic gum 10%; and (4) control (without coating). Results showed that seedborne fungi pathogens on seed of Hipa 8 rice were detected at 6-month storage consisted of Fusarium sp., Curvularia sp., Alternaria sp., Cladosporium sp., Aspergillus sp. and Penicillium sp. The detected pathogenic bacteria were Xanthomonas oryzae pv. oryzae and X. campestris pv. oryzicola. Coating formula most compatible with the rice seed of HIPA 8 was chemical pesticide + 10% arabic gum, which suppressed fungal infection from 80% to 45% at the first month and from 90% to 70% at the fifth month, suppressed populations of Xoo + Xco from 7.6 x 108 cfu/g of seed to 5.86 x 105 cfu/g of seed at the first month and 7.0 x 106 cfu/g of seed to 1.4 x 104 cfu/g of seeds at the sixth month. The treatment caused the smallest decrease of seed viability compared to the other coating treatments.

<p>Kapas (Gossypium hirsutum L.) merupakan penghasil serat alam yang digunakan untuk bahan baku tekstil. Pengembangan kapas diarahkan ke lahan-lahan marginal, walaupun sebagian ada yang ditanam pada sawah sesudah padi. Tingkat produktivitas serat kapas, saat ini masih rendah sekitar 0,8 sampai dengan 1 ton per hektar. Usaha peningkatan produksi kapas antara lain dengan pemberian zat stimulan (paclobutrazol), teruta-ma untuk memacu pertumbuhan vegetatif dan generatif seperti tinggi tanaman, jumlah cabang, jumlah bu-nga, dan jumlah buah. Kedua komponen tersebut menjadi penentu hasil serat. Paclobutrazol adalah zat stimu-lan bagi tanaman. Penelitian dilaksanakan di Kebun Percobaan Sumberrejo, Bojonegoro pada bulan Mei sam-pai dengan Oktober 2010, pada lahan sawah sesudah padi. Perlakuan disusun secara faktorial dengan meng-gunakan rancangan acak kelompok yang diulang sebanyak empat kali. Sebagai faktor pertama adalah 4 varietas kapas yang terdiri atas 1) Kanesia 8, 2) Kanesia 13, 3) Kanesia 14, dan 4) Kanesia 15. Faktor kedua adalah pemberian paclobutrazol melalui penyemprotan pada tanaman dengan dosis: a) 0; b) 1,50 l/ha diberikan sekali pada umur 60 hari; dan c) 1,50 l/ha diberikan dua kali umur 60 hari dan 75 hari. Hasil penelitian menunjukkan bahwa kapas varietas Kanesia 8 dan 13 yang ditanam di lahan sawah sesudah padi mempunyai pertumbuhan vegetatif dan generatif optimal, kemudian disusul dengan Kanesia 13, Kanesia 14, dan Ka-nesia 15. Paclobutrazol yang disemprotkan pada tanaman kapas, tidak berpengaruh nyata terhadap pertumbuhan baik vegetatif maupun generatif. Hasil kapas berbiji untuk varietas kapas Kanesia 8 dan Kanesia 13 sama, masing-masing sebesar 1.643 kg/ha dan 1.686 kg/ha.</p><p> </p><p>Cotton is a natural fibre crop for some textile raw material. The development of cotton is directed mainly to marginal lands, although few of it is planted in paddy fields after rice harvested. The productivity level of cotton fibre, is still low, about 0.8 to 1 ton per hectare. Effort to increase cotton production is done through the application of growth regulator aiming at enhancing to the growth of plant height, number of branches, number of flower, and boll. These components are fibre determinans. Research conducted at Sumberrejo Ex-perimental Garden, Bojonegoro from May to October 2010, in paddy fields after rice harvested. Factorial treat-ment arranged using randomized block design repeated four times. The first factor consisting of four cotton varieties: 1) Kanesia 8, 2) Kanesia 13, 3) Kanesia 14, and 4) Kanesia 15. The second factor is application of pa-clobutrazol by spraying the plants with usage of: a) 0, b) 1.50 l/ha given once at age 60 days, and c) 1.50 l/ ha given twice at the age of 60 days and 75 days. The research showed that Kanesia 8 and Kanesia 13 varie-ties gave optimum vegetative and generative growth followed with Kanesia 13, Kanesia 14, and Kanesia 15. Paclobutrazol did not contribute significant effect on the growth of both vegetative and generative of cotton.

Drying rice grain is one of the problems faced during the rainy season. This study aims to obtain information about the height of the tent, the thickness of the appropriate seed layer, and the interaction between the height of the tent and the thickness of the seed layer on the quality of rice seeds. The research method used is a field experiment prepared with a completely randomized block design using a split-plot design. As the main plot is the treatment of the height of the tarpaulin cover are 50, 80, and 110 cm. As a subplot is a thick layer treatment is 5, 7, 9, and 11 cm. Each treatment combination was repeated three times. The results showed that tarpaulin height has a significant effect on the parameters of the maximum growth potency and plant height at week 4. A tent height of 50 cm had the highest maximum growth potential. Layer thickness gave a significant effect on the parameters of the number of tillers at week 4 and plant height at week 4. The number of tillers in the fourth week of treatment with a layer thickness of 7, 9, and 11 cm was not significantly different but was significantly better than the layer thickness of 5 cm. The highest parameter of plant height at week 4 was 7 cm thick. There was an interaction between tarpaulin height and layer thickness on the parameters of the number of tillers at week 6, plant height at week 2 and 6.

Research aimed to evaluate the application of biological agents to promote plant growth and to control bacterial leaf blight (BLB) disease in rice seed production. This research consisted of two experiments, the first was in the nursery while the second was in the field. The first experiment conducted in a completely randomized  design with one factor (seed treatments) and three levels, i.e., control (untreated), matriconditioning + streptomycin sulphate 0.2% (BsM), biomatriconditioning + B. subtilis 5/B + P. diminuta A6 (BM). The second experiment was conducted in a randomized complete block design with one factor (biological agent aplication methods) and nine levels, i.e., control (untreated), matriconditioning +  streptomycin sulphate 0.2% (BsM), biomatriconditioning + B. subtilis 5/B + P. diminuta A6 (BM), soaking of seedlings root with  B. subtilis 5/B + P. diminuta A6 (RA), foliar spraying with Aeromonas sp. F112 (SD), BM + RA, BM + SD, RA + SD, BM + RA+ SD. The result showed that seed treatments significantly increased field emergence. Eventhough all treatments did not significantly affect plant growth, incidency and severity level of BLB disease, and yield components, biomatriconditioning showed a better improvement in yield components. The seeds produced from plants treated with the biological agents showed significantly higher vigor index than untreated and matriconditioning + streptomycin sulphate 0.2%. </em><br /><br /><em>Keywords: Aeromonas sp., Bacillus subtilis, biomatriconditioning, seed quality, Pseudomonas diminuta</em>

The aim of this study was to evaluate the influence of pod wall permeability on the physiological quality of soybean seed. The cultivars studied were Sant'Ana, FT-2, FT-10, Bossier, Davis and the breeding line F 84-7-30, with a black seed coat. Pods were collected from plants at the R4, R5, R6, R7 and R8 development stages, which composed the treatments in regard to time of harvest. The parameters of permeability and the lignin content of the pods and the seeds within the pods were evaluated. The seeds were collected just after full maturity (R8), and the following tests were performed: germination, electrical conductivity, and tetrazolium, which determined seed viability and vigor. A randomized complete block design in a split-plot in time arrangement was used, with four replications per treatment. The soybean genotypes (six) composed the plots, and the split-plots consisted of the development stages (R4, R5, R6, R7 and R8). In seed evaluation, the same design was used, reducing the number of treatments to three in the split-plots (R6, R7 and R8). Pod permeability varied with the genotype and stage of development; this affected seed vigor, but not the viability of newly-harvested seeds. The pod lignin content did not show any influence on pod permeability.
