Abstract

Various treatment were tried for efficient pod breakage which is a barrier for seed germination. Effective protocol was standardized for in-vitro germination. High per cent of healthy seedlings were obtained by supplementing the media with 0.1 mg/1 BAP. Multiple shoots were recorded when cultured on media fortified with 3 mg/1 BAP.

Abstract

A field experiment was conducted during Kharif 2009 and rabi 2009-10 at Maize Research Centre, Rajendranagar, Hyderabad with the maize hybrid (30V92) in Randomized Block Design with seven treatments for bio-efficacy i.e., coragen 30, 40, 50 and 60 g a.i/ha along with two standard checks, carbaryl 50 WP @ 700 g a.i/ha, endosulfan 35 EC @ 350 g a.i/ha and an untreated control against maize stem borers. Stem borer damage in terms of per cent infestation and per cent dead hearts in four dosages of coragen varied between 1.27 to 2.96 and 0.0 to 0.68 during Kharif, 1.06 to 5.60 and 0.0 to 4.31 during Rabi. The population of Coccinella spp. remained unaffected.Phytotoxicity symptoms were not noticed on maize crop.

Abstract

Background/Objectives: Search engines such as Google uses the indexed results to respond to the user’s query. It also uses ranking algorithm namely Pagerank algorithm to rank the web pages. Ranking mechanism works offline and the value is static. Pagerank algorithm uses uniform probability distribution and Power iteration to rank the web. Though the method is simple and efficient, applying it to large scale is not effective since the computational cost is expensive and the convergence occurs at slower rate. Methods: The proposed work Proximity Prestige algorithm uses degree prestige along with proximity prestige and the calculation method used is Incremental Iteration. In Degree Prestige, a web page has more prestige if it has many in links. Proximity Prestige is defined by the closeness of other web pages that links to that page. It uses non-uniform transition probability for computing the rank vector. Findings: This work enhances the rank of a web page. From this work it is proven that when a page is more close to its home page and if it receives more in links, its rank value increases. Applications: It can be used by the search engines to compute the rank of a web page in accordance with the proximity and the incremental iteration method could be applied in the area where computational cost is expensive.

Keywords

Abstract

A field experiment on seasonal incidence of stem borers in corn was conducted at Maize Research Centre, Rajendranagar, Hyderabad. Undertaking sowings at monthly intervals from Jan 2013 to Dec 2013 in an area of 150 m² as a replicated trial. DHM 117 hybrid was sown in ridge and furrow method at 75x20 cm spacing. Random destructive sampling was done twice at 30 and 60 DAG @ 4 plants per replication to quantify the genera wise stem borer larval population and also stem tunneling. Observations on stem borer incidence and yield were recorded. Data was subjected to arcsine and square ischolar_main transformation and two way analysis was conducted. It is evident from the results that among the monthly sowings, September and February are subjected to severe stem borer attack, however, low yields are observed in summer. Hence, it is advisable to take up sowings in July during Kharif and in November during Rabi to obtain maximum yields with low stem borer incidence.

Abstract

A field experiment was conducted during Rabi 2011-12 and Kharif 2012 at Maize Research Centre, Rajendranagar, Hyderabad with DHM 117 maize hybrid inRandomized Block Design with eight treatments for bio-efficacy of Virtako 1.5 G @ 4, 5, 6, 7 kg/ha against maize stem borer along with three standard checks, Chlorantriniliprole 0.4 G @10 kg/ha, Thiamethoxam 75 SG @ 0.125 kg/ha, carbofuran 3 G @ 33 kg/ha at 15-18 days after sowing and an untreated control. Two years pooled data shows that among all the treatments, Virtako 1.5 G @ 7 kg/ha followed by chlorantriniliprole and virtako 6 kg/ha were highly effective in reducing the stem borer damage with 3.98, 4.41, 4.78 per cent infestation and 1.99, 1.94, 2.57 per cent dead hearts, respectively compared to 11.19 per cent infestation and 5.64 per cent dead hearts in control. Virtako 1.5 G@ 7 kg/ ha and 6 kg/ha were effective in reducing the aphid population to 5.33 aphids/plant compared to 12.33 aphids/plant in control. The population of Coccinella spp. and spiders differed slightly among the treatments.Virtako did not cause any of the phytotoxic symptoms on maize even at the dosage of 12 kg/ha. Highest grain yield of 10.11 t/ha and 5.09 t/ha was obtained in the plots treated with Virtako @ 7 kg/ha as compared to 9.15 and 4.28 t/ha in control during Rabi and Kharif, respectively.

Abstract

Modeling of generation of wind power systems is useful for an effective management and balancing of a power grid, supporting real-time operations. Forecasting the expected wind power production could help to deal with uncertainties. In comparison with the mathematical approach, the data driven approach is useful where both detailed information about the system and real time measurements are unavailable. Winds being a natural phenomenon, statistical methods are more suitable for wind power plants than that of conventional power plants. In this paper, the data on the wind speed and power generated from a location in the state of Karnataka, India, has been analyzed and shown that the probability distribution of wind speed follows Rayleigh or Gaussian/Normal distribution. Short-term wind power forecasting is carried out using Autoregressive models.

Keywords

Abstract

In the field experiments conducted during Kharif 2012 and Rabi 2012-13 at Maize Research Centre, Rajendranagar to find out an alternative to endosulfan which was recommended against stem borer in maize, insecticides were sprayed at the recommended dosages at 12 DAG and observations were recorded at 45DAG and subjected to RBD analysis after angular transformation. Mean infestation was observed to be the lowest in the plot treated with chlorantriniliprole 18.5 SC (1.28%) followed by £cyhalothrin 5CS (2.33%). Mean per cent deadhearts was lowest i.e., 0.41 in the £-cyhalothrin treated plot followed by 0.61 in Indoxacarb treatment.
