The Imidacloprid insecticide, Gaucho 70 WS at 1.5, 2.5, 3.5, 4.5 and 5.5 g/kg seed was used as seed treatment and monocrotophos 40 WSC at 1120 ml/ha was applied as foliar spray on CB9 cotton cultivar to suppress aphid, whitefly and thrips, and impact on their natural enemies during 2008-2011 at the Regional Cotton Research Station, Dinajpur, Bangladesh. The activity of natural enemies, such as ladybird beetle, lacewing, syrphid, and spider population on the sucking pests attacking cotton cultivar CB9 and yield of cotton were recorded. Imidacloprid significantly reduced aphid, whitefly, and thrips population on cotton crops compared to untreated control or foliar spray of monocrotophos 40 WSC at 1120 ml/ha. Ladybird beetles, lacewings, syrphids, and spiders were abundant in the field but their population decreased in the treated plots compared to untreated control. The CB9 cotton cultivar produced significantly higher yield (1.73 t/ha) with a benefit cost ratio 12.47 when seeds were treated with Imidacloprid at 5.5 g/kg fuzzy seed. This study indicated that Imidacloprid (Gaucho 70 WS) used as a seed treatment may be suggested to the cotton growers for controlling sucking pests. Bangladesh J. Agril.

Abstrak: Pengelolaan sampah di Kota Pematangsiantar masih bertumpu pada pendekatan akhir (kumpul-angkut-buang), dengan tingkat pelayanan yang rendah, sehingga untuk meningkatkan pelayanan sampah, perlu dilakukan pemilahan di tempat penampungan sementara (TPS). Penelitian ini bertujuan untuk mengkaji sistem pengelolaan sampah dengan melakukan pemilihan di TPS dapat meningkatkan pelayanan aset persampahan sampai tahun  2015 secara teknis operasional dan dari aspek keuangan. Analisa teknis operasional aset pengelolaan sampah mulai dari pewadahan, pengumpulan dan pengangkutan sedangkan analisa keuangan dan analisa kelayakan menggunakan Net Present Value, Internal Rate of Return, Benefit/Cost Ratio, dan Payback Period. Dari hasil analisa tersebut diperoleh suatu sistem pengelolaan sampah dengan pemilihan di TPS berdasarkan zona pelayanan dengan skala prioritas secara bertahap daritahun 2013-2017, dapat meningkatkan cakupan pelayanan sampah eksisting rata-rata 6,69 %, cakupan pelayanan TPS eksisting rata-rata 8,29 %, dan cakupan pelayanan truk pengangkut sampah eksisting rata-rata 12,03 %.

Rice Processing

Rice production and processing over the years has been on an increase with more small holders entering the business. This study on profitability of processing and marketing of small scale rice processors had as objective to analyse the profitability levels of rice processing and marketing by small scale processors, determine the value added to the commodity at each stage  and also identify the constraints faced by these processors. The study used primary data collected using well-structured questionnaire from millers only, miller traders for white/parboiled rice through a multistage sampling technique. Results showed that the net processing income (3,151,201), value added (8,147,456) and efficiency (138) for miller-traders of white rice was highest, followed by miller-traders for parboiled rice and lastly millers only. Results further showed that millers only had Benefit/cost ratio of 0.4 indicating that milling only is not profitable due to small quantities milled, and high fixed cost. Miller-traders for parboiled rice had a benefit/cost ratio of 2.3 implying that their venture is most profitable. Based on the results, it was recommended that millers only should purchase large quantities of paddy to enable them reduce the overhead cost. Also the services of parboilers should reflect in the sales price of parboiled rice so that the parboiling services can be paid for.

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

These books are numbers 4 and 5, respectively, in the series "Studies in the Economic Development of India". The two books are interesting complements to one another, both being concerned with the analysis of projects within national plan formulation. However, they treat different sorts of problems and do so on very different levels. Marglin's Public Investment Criteria is a short treatise on the problems of cost-benefit analysis in an Indian type economy, i.e., a mixed economy in which the government accepts a large planning responsibility. The book, which is wholely theoretical, explains the many criteria needed for evaluation of projects. The work is aimed at beginning students and government officials with some training in economics. It is a clear and interesting "introduction to the special branch of economics that concerns itself with systematic analysis of investment alternatives from the point of view of a government".

Penelitian ini bertujuan untuk menganalisis tingkat pelayanan simpang berdasarkan data lalu lintas simpang tersebut apakah derajat jenuhnya sudah melewati ambang batas DS = 0,75, jika nilai DS>0,75, akan dikaji penerapan beberapa alternatif penanganan untuk meningkatkan tingkat pelayanan simpang, untuk kemudian dipilih lagi alternatif terbaik untuk jangka pendek, menengah dan panjang. Metode pengumpulan data yang digunakan dalam penelitian ini adalah metode traffic counting, sedangkan untuk pengkajian alternatif penanganan simpang secara teknik menggunakan metode MKJI 1997, secara ekonomi menggunakan metode LAPI ITB, analisa nilai waktu dengan nilai waktu hasil penelitian Dirjen Bina Marga dan analisa biaya investasi dengan analisa Benefit Cost Ratio dan Net Present Value.  Dari tiga alternatif manajemen lalu lintas yang diajukan, hanya alternatif ke-3 yaitu kombinasi peniadaan hambatan samping, pelarangan belok kiri dan optimasi traffic light  yang menghasilkan nilai DS<0,75 untuk kondisi eksisting, sedangkan untuk tahun 2020 nilai DS-nya adalah 0,79 untuk Hari Selasa dan 0,83 untuk Hari Rabu. Sedangkan dengan alternatif pembangunan flyover, untuk jangka pendek atau 5 tahun nilai BCR dan NPV-nya 1,25 dan 48,9 milyar rupiah, tahun ke-10  2,29 dan 256,4 milyar rupiah, serta tahun ke-15 3,35 dan 472,19 milyar rupiah, sehingga dapat disimpulkan bahwa pembangunan flyover adalah solusi penanganan terbaik untuk menignkatkan kinerja Simpang Pasar Pagi Arengka.
