Wheat seedlings pre-exposed to aluminum (Al) prior to fungal inoculation resulted in enhanced hydrogen peroxide (H2O2) content in the roots coupled with increase in glutathione (GSH) and salicylic acid (SA) levels in the shoots, which were not directly inoculated with the pathogen. Over-accumulation of GSH and SA at the shoot level indicated systemic expression of enhanced defense responses upon pathogen attack. Higher concentrations of GSH and SA in the shoots induced resistance responses, which were manifested through the biochemical imprint of the seedlings. Aluminum pre-exposure before pathogen inoculation resulted in significant increase in the assimilatory pigments, total soluble carbohydrates and total phenolic compounds on 7 and 14 days after inoculation as compared to untreated control seedlings. Untreated seedlings infected with Fusarium showed significant decline in the biochemical parameters studied and were highly susceptible to the pathogen. Disease severity index calculated in case of Fusarium infected seedling was significantly higher than co-stressed seedlings. © 2016, Indian Society for Plant Physiology.

A detailed soil fertility inventory study was carried out in Bhadrak district of Odisha during 2012-13 using the Global Positioning System (GPS) and Geographical Information System (GIS) tools. Geo-referenced soil samples were collected from the different villages in each blocks of the district. Soil samples were processed and analysed in laboratory for pH, EC, organic carbon, available nitrogen, phosphorus, potassium, sulphur and boron. The results reveal that soils of all the blocks were found to be acidic (4.9 to 5.2) in reaction and medium to high in organic carbon content (6.1 to 9.4 g kg-1)-Available soil nitrogen content was low (148.9 to 190.7 kg N ha-1), available soil phosphorus content was low to medium (3.7 to 17.8 kg P ha-1) whereas, available soil potassium content was medium to high (178.9 to 484.3 kg K ha-1). On the other hand, available sulphur was found to be deficient in some blocks and sufficient in other blocks of the district (8.04 to 32.86 mg S kg-1). Hot water soluble boron content remained above the critical limits (0.57 to 1.03 mg kg-1) in all the blocks. The soil fertility maps of Bhadrak district were prepared by using the Arc GIS software. The generated data and maps are very useful for planning, monitoring and evaluation of soil fertility status for sustainable crop production.

A field experiment was conducted at Main Agricultural Research Station (MARS), Agriculture College, Dharwad to study the effect of sequential application of herbicides on microbial activities and yield of maize. Six herbicides, namely, glyphosate, paraquat, glufosinate ammonium, saflufenacil, halosulfuron and imazathapyr were tried as post-emergence in addition to pre-emergence application of atrazine. Totally nine treatments were tested using randomized block design having three replications with three controls [Weedy check, weed free check and standard recommended package of practices (RPP)]. Weed free check was recorded higher weed control index (WCI) than rest of the weed control methods at all the growth stages of maize. However, the treatment, pre-emergence application of atrazine @ 1 kg/ha fb post-emergence application of glyphosate @ 2.5 kg/ha recorded WCI of 92.12% next to weed free check. Weed free check recorded significantly higher grain yield (84.59 q/ha), stover yield (114.10 q/ha) and harvest index (42.57%). At different growth stages of maize, both pre- and post-emergence applications of herbicides, all the enzymatic activities in the soil were reduced as compared to untreated plots. © 2016, Gaurav Society of Agricultural Research Information Centre.

This paper introduces a method of preference analysis based on electroencephalogram (EEG) analysis of prefrontal cortex activity. The proposed method applies the relationship between EEG activity and the Egogram. The EEG senses a single point and records readings by means of a dry-type sensor and a number of electrodes. The EEG analysis adapts the feature mining and the clustering on EEG patterns using a self-organizing map (SOM). EEG activity of the prefrontal cortex displays individual difference. To take the individual difference into account, we construct a feature vector for input modality of the SOM. The input vector for the SOM consists of the extracted EEG feature vector and a human character vector, which is the human character quantified through the ego analysis using psychological testing. In preprocessing, we extract the EEG feature vector by calculating the time average on each frequency band: θ, low- β, and high- β. To prove the effectiveness of the proposed method, we perform experiments using real EEG data. These results show that the accuracy rate of the EEG pattern classification is higher than it was before improvement of the input vector. © 2014 IEEE.

The post- emergence application of quizalofop ethyl at 1.0 kg ha-1 at 15 DAS with one hand weeding at 25 DAS was the most effective and economical for controlling the grassy weeds in groundnut with maximum pod yield and haulm yield of 22.6 q ha-1 and 20.46 q ha-1, respectively. This treatment also minimized nitrogen, phosphorus and potash removal by weeds to a tune of 91.2, 84.1 and 89.7%, respectively over that of weedy check, resulting in better nutrient uptake by the crop. The maximum dry weed biomass at harvest was 250.3 g m-2 in weedy check followed by quizalofop ethyl at 0.75 kg ha-1 at 25 DAS. The weed control efficiency was highest (72.3 %) in application of quizalofop ethyl @1.0 kg ha-1 with one hand weeding, which gave maximum benefit- cost ratio of 2.49 and net return of Rs.53067 ha-1 with additional income of Rs.36534 ha-1 over weedy check.

Dissipative effect on magnetohydrodynamic (MHD) mixed convective unsteady flow of an electrically conducting fluid over a stretching sheet embedded in a porous medium subject to transverse magnetic field in the presence of non-uniform heat source/sink has been investigated in this paper. The method of solution involves similarity transformation. The coupled nonlinear partial differential equations governing flow, heat and mass transfer phenomena are reduced into set of nonlinear ordinary differential equations. The transformed equations are solved numerically by using Runge-Kutta fourth order method associated with shooting technique. The numerical computation of skin friction, Nusselt number and Sherwood number is presented in tables. The work of previous authors is compared with the present work as particular cases in the absence of unsteady parameter, solutal buoyancy, Darcy dissipation and chemical reaction. The results of steady and unsteady cases are also discussed. The important findings are as follows: effect of electric field enhances the skin friction contributing to flow instability. Higher Prandtl number is suitable for the reduction of coefficient of skin friction which is desirable. © 2015 Faculty of Engineering, Ain Shams University.

Now this era of Agriculture is treated as ICT mediated Market Led Agriculture Extension era. So in this Information revolution age we can't able to survive without Information. As per R.T.I. act 2005 every person deserves his/her right for Information. So by giving respect to Information we should create a Revolution on Information by the enchanting mantra "Soochana se Samadhan".India is second largest producer of commodities such as fruits and vegetables. One of the key issues, which require research, is the method by which we can reduce the post harvest loss, which is quite substantial at present. This would need design of cost effective, efficient, environment friendly storage system. Also, there is need for value addition to agricultural produce to maximize the agriculture return. This paper attempts to highlight the importance of ICT in improving marketing activities of retail business in agricultural areas in Indian economy. This paper also discusses vast potential of implementing the same in Indian agricultural business activities with some success stories, models for justification of the importance of ICT in Agriculture Retail Marketing. © 2015 The Authors.

Boron and molybdenum are essential micronutrients required for normal plant growth and development of vegetative and reproductive parts including yield. But the deficiency of these micronutrients causes many anatomical, physiological and biological changes and has threatened the cultivation of cole crops. Keeping this in view, the present investigation was undertaken to study the effect of organic manures, micronutrients and bio-fertilizers on growth, yield and management of physiological disorders in broccoli (Brassica oleracea L. var. Italica Plenck) during 2008-09 and 2009-10 at Regional Research and Technology Transfer Station, Keonjhar, Odisha. Out of 24 treatment combinations, the treatment M3F5 (100% RDF + bio-fertilizer + boron @ 18 kg ha-1 + ammonium molybdenum @ 1.8 kg ha-1 + FYM @ 5 t ha-1 + vermicompost @ 2.5 t ha-1) recorded the highest curd yield (139.5 q ha-1) and 82% less incidence of stem cracking as well as whiptail disorder than control. Higher levels of ascorbic acid, reducing sugar and total sugar were also recorded in broccoli manured with FYM and vermicompost as compared to other treatment combinations. It also resulted better quality curd, but comparatively low yield. The highest cost of cultivation (Rs. 43,508/-) per hectare was recorded under the treatment supplemented with vermicompost @ 5 t ha-1 + 100% RDF (150:45:80 kg ha-1) + bio-fertilizers (Azotobacter + Azospirillium + PSB @ 2 kg each ha-1) + boron @ 18kg ha-1 +molybdenum @ 1.8 kg ha-1. The maximum gross income of Rs. 2,09,235/-and benefit cost ratio of 5.1 were recorded when broccoli crop was grown by applying 100% RDF + bio-fertilizer + Boron @ 18 kg ha-1 + molybdenum @ 1.8 kg ha-1 + FYM @ 5 t ha-1 + vermicompost @ 2.5 t ha-1 by spending Rs. 41,188/-. It was concluded that out of 24 treatments application 100% RDF + bio-fertilizer + boron @ 18 kg ha-1 + ammonium molybdenum @ 1.8 kg ha-1 + FYM @ 5 t ha-1 + vermicompost @ 2.5 t ha-1 was ideal for effective yield and less incidence of stem cracking as well as hollowness of stem.

Farming system research is a multi-disciplinary holistic approach to solve the problems of small and marginal farms. Small and marginal farmers are the core of the Indian rural economy constituting 80% of the total farming community but possessing only 36% of the total operational land. The declining trend of per caput land availability poses a serious challenge to the sustainability and profitability of farming. Under such conditions, it is appropriate to integrate land-based enterprises, viz. dairy, fishery, poultry, duckery, apiary, field and horticultural crops within the farm, with the objective of generating adequate income and employment for these small and marginal farmers and thereby improved livelihoods. The production system adopted during Green Revolution has been explorative and the natural resources like soil and water were subjected to immense pressure beyond carrying capacity. As a result sustainability of agricultural production system and the farming system is in crises. This suggests the urgent need of integrated farming system development where the various components of the farming system may be integrated to improve productivity and profitability as well as resource conservation along with maintenance of the environment. Rice (Oryza sativa L.) occupies a position of overwhelming importance in Asian agriculture and it constitutes the bulk of the Asian diet. For many people in the poor countries, rice is the main source of energy, and it plays an important role in providing livelihood to the Asian population. It is largely grown in Asia (90% area) under diverse conditions of soil, climate, hydrology and topography. Rice farming is the single most important source of employment and income for the majority of rural people in these regions. Among the various farming system options in rice ecologies, rice - fish farming has great potential particularly in eastern India in view of the resources, food habits and other socio-economic conditions. Rice-fish diversified farming system with the integration of compatible components, such as improved varieties of rice, fish, prawn, pulses, oilseeds, horticultural crops, agroforestry, mushroom, poultry, duckery, goatery, floriculture, apiculture etc. can increase the farm productivity, besides farm employment over traditional rice farming. There exist chain of interactions and flow of resources among the different enterprises in a integrated farming system. To make farming profitable and improve resource use efficiency at the farm level, the synergy among interacting components of farming system needs to be exploited. In this paper focus is on different aspect of rice-based farming system involving methodology, determinants, and forms of rice-based farming systems and their impact on livelihood of farming communities.
