Seeds used to plant wheat, corn and rice crops in Brazil are treated with the insecticide carbofuran associated with the dye rhodamine B, attracting granivorous birds and causing mortality during sowing. The objective of this study was to evaluate if using camouflaged seeds can minimize mortality caused by the ingestion of seeds with carbofuran. Alternatives for reducing mortality, such as using carbofuran without rhodamine B or replacing carbofuran by carbosulfan, were compared. Three experiments were carried out in regions of known bird mortality in the states of Paraná and São Paulo, Brazil, using conventional sowing over plowed soil in the traditional planting system, 15,896 kg of seeds in 111.46 ha. Bird carcasses were collected and dissected to unveil which poisoned seed treatments had caused birds' deaths. The mortality mounted to 296 birds of 11 species. Eared doves were the most numerous casualties (263). There was significant correlation between mortality and number of consumed seeds. The consumption of camouflaged seeds was lower than that of commercial seeds treated with rhodamine B. The mortality caused by seeds with both rhodamine B and carbofuran was higher than mortality caused by seeds camouflaged only with carbofuran. The replacement of carbofuran with carbosulfan also seemingly reduced mortality, but carbosulfan mortality might have been underestimated as a result of the apparent movement of affected birds after exposure. Seeds treated with carbofuran and rhodamine B and without any dye, were attractive. Because legal requirement for seeds treated with pesticides to be differentiated by dying, the substitution of rhodamine B by camouflaging must be encouraged.

Currently, planting onion through seedling production is predominant in the state of Rio Grande do Sul. Thus, the present work aimed to evaluate the agronomic potential of new onion genotypes as a function of the planting system for this region. Eleven genotypes were evaluated, as follows: “commercial genotypes” Bola Precoce, Mulata, Sprint, Suprema and “pre-commercial genotypes” TE 201, TE 209, TE 216, TE 230, TE 242, TE 316 and TE 329, submitted to four planting systems: seedling production, seedling production with leaf pruning before transplanting, no-tillage manually planted at the definitive site and seedling production in trays. Treatments were arranged in an 11 x 4 factorial scheme (eleven genotypes and four planting systems). Although little practiced, the no-till system for onion cultivation for the northwestern region of Rio Grande do Sul can potentially be explored. Genotypes that best adapted to this system were: Bola Precoce, Suprema, Sprint, Mulata and TE 201. Comparatively, “commercial” genotypes showed an increase of 10.81 t ha-1 in relation to “pre-commercial” genotypes in the no-till system, proving the efficiency of this system.

<p>Abstract : One of the efforts to increase the productivity of paddy rice by setting the<br />right spacing. At this time,  developing technology engine planting of rice seedlings<br />(rice transplanter) which introducing plant spacing ranging from narrow spacing to<br />large plant spacing both on legowo row planting system and tile planting system. With<br />regard to the introduction of these technologies, further research is needed in the<br />effect of plant spacing on growth, productivity (grain yield) and income of paddy rice<br />farmers. The assessment was carried out on the wetland of farmer group of Rukun<br />Tani Sulur  Blimbing Village of Sragen Regency on July – October 2014. The<br />assessment consisted of 3 planting distance treatment of legowo row 2: 1 planting<br />system, ie 20 x 10 x 40 cm, 20 x 13 x 15 cm and 20 x 15 x 40 cm, each treatment<br />repeated 7 times. The area of each treatment is about 0.33 ha. The assessment<br />involves 7 farmers, each farmer carrying out 3 treatment. The seedlings using legowo<br />2:1planting system of rice transplanter. This rice transplanter has 3 combination of<br />plant distance, that is 20 x 10 x 40 cm, 20 x 13 x 15 cm and 20 x 15 x 40 cm. The data<br />collected includes the number of productive tillers, productivity, input and output of<br />farming. Data analysis to compare between 3 treatment by using paired t test. While<br />the analysis of financial feasibility of paddy farming technology using partial budget<br />analysis. The results of this assessment showed that a legowo row 2:1 planting system<br />with plant distance 20 x 15 x 40 cm resulted in highest productive tillers, productivity<br />and income compared to the legowo 2:1 with a narrower plant distance 20 x 10 x 40<br />cm and 20 x 13 x 40 cm.</p><p> </p><p>Abstrak: Salah satu upaya untuk meningkatkan produktivitas padi sawah melalui<br />pengaturan jarak tanam yang tepat. Pada saat ini, berkembang teknologi mesin tanam<br />bibit padi (rice transplanter) yang mengintroduksikan jarak tanam mulai dari jarak<br />tanam sempit sampai dengan jarak tanam lebar baik pada sistem tanam jajar legowo<br />maupun sistem tanam tegel. Berkenaan dengan introduksi teknologi tersebut perlu<br />dilakukan penelitian lebih dalam pengaruh jarak tanam terhadap pertumbuhan,<br />produktivitas (hasil gabah) dan pendapatan petani padi sawah. Pengkajian<br />dilaksanakan pada lahan sawah kelompok tani Rukun Tani Sulur  Desa Blimbing Kec.<br />Sambirejo Kab. Sragen Jawa Tengah pada MT-3 2014. Pengkajian terdiri dari 3<br />perlakuan jarak tanam pada sistem tanam jajar legowo 2:1, yaitu  20 x 10 x 40 cm, 20<br />x 13 x 15 cm dan 20 x 15 x 40 cm dengan 7 kali ulangan. Luas masing-masing<br />perlakuan sekitar 0,33 ha.  Pengkajian melibatkan 7 orang petani, setiap petani<br />melaksanakan 3 perlakuan. Tanam bibit padi menggunakan mesin tanam bibit padi  4<br />baris sistem tanam jajar legowo 2:1. Mesin tanam ini mempunyai 3 kombinasi  jarak<br />tanam, yaitu  20 x 10 x 40 cm, 20 x 13 x 15 cm dan 20 x 15 x 40 cm.  Data yang<br />dikumpulkan meliputi jumlah anakan produktif, produktivitas, input dan output<br />usahatani.  Analisis data untuk membandingkan antara 3 perlakuan jarak tanam dilakukan uji t berpasangan dengan menggunakan software SPSS Statistics 17.0. <br />Sedangkan analisis kelayakan finansial teknologi usahatani padi sawah menggunakan<br />analisis anggaran parsial.  Hasil pengkajian menunjukkan bahwa sistem tanam jajar<br />legowo 2:1 dengan jarak tanam lebar (20 x 15 x 40 cm) menghasilkan jumlah anakan<br />produktif,  produktivitas dan pendapatan yang lebih tinggi dibandingkan sistem tanam<br />jajar legowo 2:1 dengan jarak tanam yang lebih sempit (20 x 10 x 40 cm dan 20 x 13 x<br />40 cm).</p>

This study aims to analyze how much profit is gained by applying the Legowo row planting system, analyzing the factors of production that affect rice production by applying the Legowo row planting system, analyzing whetherthe use of production factors allocated by farmers to the Legowo planting system economically already efficient. The study was conducted from January to April 2019 in Tomohon Barat Subdistrict, Tomohon City, North Sulawesi Province. The research location was chosen purposively with the consideration that West Tomohon Subdistrict was the center of rice production in Tomohon City with a total area of 447.40 ha of rice fields ( 52% of the total area of rice fields in Tomohon City). The method used in this study is a survey method in the Kelurahan that has paddy fields in the West Tomohon District with interview techniques to respondent farmers. Determination of the sample is done by quota sampling method as many as 50 people taken from 7 (seven) villages in the District of West Tomohon by considering the area of land and the purpose of farming (commercial farm). The variables to be examined in this study are age, education, business experience, group membership, land area, seeds, fertilizer (Urea, SP36 and NPK), labor (HKSP), production, and price. The results showed that the benefits of lowland rice farming with the application of the legowo planting system, farmers in Tomohon Barat Subdistrict, Tomohon City were not yet maximum and had not yet reached economic efficiency, production factors affecting rice production were land area, seeds, fertilizer (Urea, SP 36 and NPK Phonska) and labor, the use of production factors of land area, fertilizers(Urea, SP 36 and NPK Phonska) have not reached economic efficiency, the use of seed production factors and labor is inefficient.*eprm*
