Abstract: This research is geared towards employing modern technology to enhance agricultural productivity through local and mechanized farming systems. The research work involves the construction of a device that controls water flow in an irrigation system most especially, in areas where there is acute shortage of water supply or insufficient rainfall which may be due to climate change resulting or causing draught and other environmental conditions. It is a device that is solar powered, as an alternative source of power supply to the entire irrigation system. The solar power supply consist of two modules or panels, a battery and charge regulator whose function is to control the battery charge and as well supply power to the load (motor) at various weather and soil moisture conditions. The device was tested and it was (is) able to minimize electrical power consumption, with a flow rate of water averaging at 20 liters per minute, due to the pump size and capacity. The humidity of the soil is detected by the soil moisture sensor which determines the voltage levels at which the water pump switches on/off. Also, there is an ultraviolet light sensor that enables the controller to switch off the pump during the period of higher intensity of sunlight, owing to the fact that most crop plants are irritated by water when the sun is very hot. The water pump is a D. C submersible type. An algorithm was designed for the smooth operation of the entire system.

Abstract: This paper proposes the design and implementation of an enhanced binary multiplication technique. Vedic Mathematics is a system of mathematics that was discovered by Indian mathematician Jagadguru Shri Bharathi Krishna Tirthalji in the period between 1911 and 1918. The main objective of this paper is to design an improved binary multiplier which is faster and low-powered. The performance of our proposed full adder design is proven to be more effective in comparison with the standard full adder cell both designed in 90nm. The proposed modified 2-Bit and 4-Bit Vedic multipliers also beat the existing Vedic multiplier based in Urdhva Tiryagbhyam sutra in terms of operating frequency, energy and area. ThedesignsareimplementedoncadenceVirtuoso90nmCMOStechnology operating at 2V supply. Comparedtotheexisting standard fulladderdesigns in 90nm, the proposed implementation has shown that it offers significant improvements in terms of power and speed consuming 60% less power and is able to operate 20% faster. The proposed 2-Bit multiplier operated at 2V is proven to be more effective. The design was further extended to realise a 4-Bit multiplier. The power consumed by the standard 4- Bit multiplier designed using standard 90nm cells was 361.2µW and the power consumed by the proposed 4-Bit multiplier design was found to be 290.2µW, which reflectsa 20% decrease in the power usage.
