In the field of agriculture, use of proper method of irrigation is important because the  main reason is the lack of rains and scarcity of land reservoir water. The continuous extraction of water from earth is reducing the water level due to which lot of land is coming slowly in the zones of  un-irrigated land. Another very important reason of this is due to unplanned use of water due to which a significant amount of water goes waste. The system derives power from solar energy through photovoltaic cells. Hence, dependency on erratic commercial power is not required. In this paper we use solar energy which is used to operate the irrigation pump. The circuit comprises of sensor parts built using op-amp IC. Op-amp’s are configured here as a comparator. Two stiff  probes are inserted in the soil to sense whether the soil is wet  or dry. A microcontroller is used to control the whole system by monitoring the sensors and when sensors sense dry condition of soil, then microcontroller will send command to relay driver IC the contacts of which are used to switch on the motor and it will switch off the motor when the soil is in wet condition. The microcontroller does the above job as it receives the signal from the sensors through the output of the comparator, and these signals operate which is stored in ROM of the microcontroller. The condition of the pump i.e., ON/OFF is displayed on a 16X2 LCD which is interfaced to the microcontroller. Further it can be enhanced in future by interfacing it with a GSM modem to gain control over the switching operation of the motor.

ABSTRACT: The aim of the present study is to evaluate the energy balance and energy efficiency of the silage maize crop in the Center for Research, Development and Technology Transfer of the Universidade Federal de Lavras (CDTT-UFLA). The crop was irrigated by center pivot and the stages of maize cultivation and energy inputs were monitored for the 1st and 2nd crops of the 2014/2015 harvest. Results from the energy analysis showed the crop had a total energy input of 45,643.85 MJ ha-1 and 47,303.60 MJ ha-1 for the 1st and 2nd crops and a significant predominance of direct energy type (about 92% of the matrix). Regarding direct energy inputs, the diesel oil was the most representative, contributing with approximately 38% of the total energy demand. Conversely, the irrigation system contribute with 3.92% e 5.97% in the 1st and 2nd crops, representing the largest indirect energy input. Nevertheless, irrigation and crop management allowed the system achieving high levels of productivity, resulting in an energy efficiency of 25.1 and 28.1 for the first and second crops respectively.

The high-content bipolar phosphor (ppy)2Ir(dipba) can dominate the EL process and the recombination zone is almost broadened as wide as the whole EML in D4, leading to remarkably higher efficiency level of D4 than that of D2 based on (ppy)2Ir(acac).
