Abstract

Field experiment with banana crop was conducted on moderately drained clayey soil which was classified earlier as “deep black soil” in Southern Gujarat. The study indicated that the fertilizer sources influenced significantly on growth parameters. Maximum plant height (3rd and 7th MAP), stem girth (3rd, 5th and 7th MAP), total leaf area (3rd and 5th MAP) was recorded with water soluble fertilizer (S2). Moreover, fertilizer sources and fertigation frequencies failed to exert any significant effect on crop duration. Considering the effect of fertigation levels, viz., 80 % RDF (L3) and fertigation frequencies, viz., fertigation applied at twice in a week (F2) induced early and vigorous vegetative growth was observed in terms of plant height, stem girth, number of leaves and total leaf area at various stages of growth of banana i.e. at 3rd, 5th and 7th MAP, and after harvest in banana cv. Grand Naine. The treatment L3 (80% RDF) was also found better with respect to crop duration parameters viz., early initiation of inflorescence, maturity of the fruit as well as total crop duration. In drip control vs. rest, all the rest of the treatments except 40% RDF (L1) were recorded higher values in plant height. However, stem girth and total leaf area were recorded maximum in treatment S2 (WSF), L3 (80% RDF) and F2 (twice in a week) as compared to drip control.

Abstract

Todays engineering research is highly motivated towards the nature inspired metaheuristic computational algorithm as they have the capability to give better results as compared to the conventional methods. Wireless Sensor Networks(WSNs) have become increasingly popular due to their extensive array of applications. Desing of energy efficient routing algorithms is an important issue in the designing of WSNs applications as the lifetime of the sensor node is based on the limited battery powered devices. Therefore to maximize the lifetime of sensor node a comprehensive survey of energy efficient routing algorithms based on natural science have been addressed in this paper. The paper will take the readers into the detailed survey of existing energy optimized routing algorithms considering the natural science (metaheuristic) as the base and considering parameters related to energy efficiency as the core objective. The final part of the paper discusses the limitations of various algorithms that has been addressed in this paper and suggestions to overcome them.

Abstract

In this paper, a new design of wireless sensor network (WSN) node is discussed which is based on components with ultra low power. We have developed a Low cost and low power WSN Node using MSP430 and nRF24L01. The architectural circuit details are presented. This architecture fulfils the requirements like low cost, low power, compact size and self-organization. Various tests are carried out to test the performance of the nRF24L01 module. The packet loss, free Space loss (FSL) and battery lifetime calculations are described. These test results will help the researchers to build new applications using above node and to work efficiently with nRF24L01.
