of Research Findings The project has now completed two crop-years of experimentation. Four more crop-years are required for all crop rotations to complete a full cycle. This report covers the 2004-05 cropyear results. CBARC experiment (Moro): Grain yields of winter wheat following fallow (conventional or chemical) produced significantly higher yields than yields of annual cropping systems invol...

Cropping system level study is not only useful to understand to overall sustainability of agricultural system, but also it helps in generating many important parameters which are useful in climate change impact assessment. Considering its importance, Space Applications Centre, took up a project for mapping and characterizing major cropping systems of Indo-Gangetic Plains of India. The study are...

Multiple cropping, a common practice of intensive agriculture that grows crops multiple times in the agricultural land in one growing season, is an effective way to fulfill the food demand given limited cropland areas. Deriving cropping cycles from satellite data provides the spatial distribution of cropping intensities that allows for monitoring of the multiple cropping activities over large a...

This paper presents a new technique for copyright protection of images using integer wavelet transform (IWT), singular value decomposition (SVD) and Arnold transform. We divide the cover image into four sub-images by picking alternate pixels from consecutive rows and columns and embed the copyright mark into the sub-image having the largest sum of singular values. The embedding is done by modif...

In order to reduce the cropping force and enhance the cropping cross-section quality, a new type of cropping machine is proposed in this paper. The basic structure and working principle of the cropping machine are introduced. Based on D'Alembert's principle, the vibration equations of the cropping machine along the Y direction, X direction and around X, Y, Z axis are built in detail and the mot...

Yield gap analyses of individual crops have been used to estimate opportunities for increasing crop production at local to global scales, thus providing information crucial to food security. However, increases in crop production can also be achieved by improving cropping system yield through modification of spatial and temporal arrangement of individual crops. In this paper we define the croppi...

Predicting the hydrologic consequences of biomass cropping systems requires an understanding of how different crops and management practices affect soil hydraulic properties across space and time. To inform such predictions, I investigated the impacts of five biomass cropping systems on the hydraulic properties of soils across a landscape gradient in wet, dry, and average rainfall years. I used...

In a first step, we present what we call the " symbolic virtualization " that illustrates the " consumer-oriented " dimension of finance where recent marketing methods present the financial market as a " fashion game ". We also emphasize the speculative impacts of this evolution. We introduce then what we call the " technological virtualization " of finance, that derives from the growing comput...

Virtual and distributed collaboration are increasingly important for organizations. This paper presents episodes of negotiated term definitions used to complete tasks in a voluntary, ad hoc game forum of an Alternate Reality Game (ARG). Episodes analyzed focus on specialized language used during problem solving. Terminology analysis reveals that players do not explicate definitions and construc...

Continuous cropping changes soil physiochemical parameters, enzymes and microorganism communities, causing "replant problem" in strawberry cultivation. We hypothesized that soil nematode community would reflect the changes in soil conditions caused by long-term continuous cropping, in ways that are consistent and predictable. To test this hypothesis, we studied the soil nematode communities and...
