Irrigation Water Management and Crop Production

Agriculture being a key element of the national economy is challenged by variety of problems in development planning. Among these the major ones are climatic changes, topographic constraints, population pressure, ecological degradation & low level of technological advancement, so it needs good potentials of agricultural development. One of the mitigation to reduce challenges of this development is Irrigation practices Looking at this Irrigation Project area, it is with trace amount of rainfall over the year, this does have direct impact on human & cattle population, so it has to be supported by irrigation. Residents of the area develop Teff, Maize & sorghum though the available rain is not promising to harvest yield that even can feed few months. There is no promising grazing area for the cattle of the area too. Irrigation from its very nature has the capacity to solve animal feeds. The methodology used in this development study was aimed at plainly defining and describing the agronomic situation of the area and out lining the major crop production constraints and developing recommendation for implementation. Primary and secondary data were collected from the Kebele development agents, farmers and Wareda agricultural and development office using checklists through group discussion and key informant interview on crop production, cropping pattern, farming practice and production constraints. Crop water requirements of crops are computed using crop wat 4 windows model. In general, as a conclusion the agro-climatic condition of the project site, the suitability of the soil for crop production, physical feature of the command area and the availability of irrigation water are suitable for development of irrigation. Despite the above facts, the sustainability of the project is very much dependent on the full participation of the beneficiaries in all aspects of the project implementation. The participatory approach will create a sense of responsibility and ownership and greatly contributes to the success of the irrigation schemes constructed in previous years.

Effect of the Fungicide Dimethomorph at Different Application Rates on Enzyme Activities in Groundnut (Arachis Hypogaea l.) Soils

Soil microbial diversity is indispensable to maintain functional diversity and enzyme-mediated critical soil processes that detoxify soil from environmental pollutants, like pesticides. Thus, the present study was carried out to assess the effect of different concentrations of the fungicide dimethomorph on the activities of phosphatase, and urease, of black and red soils of groundnut cultivated fields of Anantapuramu District , Andhra Pradesh, India

Study Of Mechanical Behavoir Of Composite Material By Vibration Analysis

In present time there is an increasing need for an alternative material to conventional materials. Growing interest in using environmental friendly materials brings natural fiber made the composite material in focus. They are strong, lightweight, cheap and biodegradable. But one needs to check whether its properties satisfy that of existing material. The target of the study is to experimentally justify biaxial fiber composite as a promising alternate material. The polymer composite samples are made with natural/synthetic fiber as reinforcement and a synthetic resin as matrix material. To find its natural frequency and damping of the composite materials, vibration test is carried out. ANOVA technique is used to find the level of the parameter.

Implementation of Secured Sensor Nodes Using Cryptographic Algorithms

Application of wireless sensor networks (WSN) to commercial, home environments and military purpose are increased in wide range. As the wireless sensor networks continue to grow, they are vulnerable to attacks and hence need for security mechanisms. Identifying suitable cryptography for WSN is important challenge due to limitation of energy, computation capacity and storage resources of sensor nodes. For this purpose, Cryptography plays a vital role in securing the data in W SN. In this paper we implemented two symmetric cryptographic algorithms algorithms: block cipher AES (Advanced encryption standards) and the Lightweight block cipher PRESENT. Our main aim of implementing the symmetric cryptographic algorithms in sensor nodes to provide secure communication which guarantees the confidentiality, integrity and avoids key exchange via unsecured channel that impose real threats. The experimental results are carried by implementing these algorithms in Atmega 32 bit microcontroller using simple C codes.

Experimental Investigation of Mortar Cube with Pumice Powder and Ceramic Tile Powder

An experimental investigation was carried out to evaluate the properties of cement Mortar. In this project study, ordinary Portland cement is replaced partially with pumice powder and fine aggregate is replaced partially with ceramic tile powder. In this research is to study the utilization of ceramic waste as a partial replacement of fine aggregate in a mortar. In this experimental investigation, prepare mortar cube of size 70.7mm x 70.7mm x 70.7mm with mix proportion 1: 3. The aim of this study is to determine the optimum % replacement of pumice powder in mortar cubes. .Cement mortar is made by replacing cement with pumice powder of different percentages like 5%, 10%, 15%, 20% & 25% with curing of 3, 7 & 28 days. The various combinations of pumice powder and ceramic waste powder were added to the mortar. Compressive strength test, splitting tensile strength test, water absorption test and the density test were performed and the results were analyzed. Mortar cube shows light weight behavior by replacing cement with pumice powder. The density of mortar is decreasing by adding pumice powder. The density of mortar cube is increasing by adding pumice powder and ceramic tile powder. Mortar cube shows almost similar strength compare to conventional mortar by adding pumice powder and ceramic tile powder.

Implementation of Anonymous and Secure Communication System with Group Signatures

For Privacy Preserving Communications Both Anonymity and end to end encryption mechanism is essential. Identity Based Encryption technique is best suitable for secure and anonymous communications. For solving anonymous and secure communication problems both cryptographic and IBE based protocols needed which governs the proper communication between two parties. For the purpose of authentication of the user proxy server is maintained between user and service providers. The GM and KGC is essential in anonymous communication for issuing both signing and decryption keys for getting plaintext from ciphertext in original form. Public key encryption and digital signature mechanism needed for guarantees of secure communication between both ends. Finally protocol realizes secure and anonymous communication between sender and receiver. The Communication Protocol along with IBE and Group signatures allow secure anonymous authentication. In this way, illegitimate users cannot use anonymous system and cannot effect the communication between source and destination whereas legitimate users access systems without compromising anonymity. In this way the proposed system get secure and anonymous communication over the network. Keywords: Anonymous Communication, Anonymous Authentication, Secure Channel, Identity-Based Encryption, Group Signature.
