In South-Eastern Nigeria, during the dry season from November to April, vegetables are always in short supply and consequently expensive. Hence, there is a need to design, develop an affordable and simple bucket drip irrigation system that can be used to grow vegetables under limited water supply conditions. Using the estimated consumptive use of the proposed crop okra and the area occupied by the crop stands, the capacity of the bucket as a source of water was computed. The bucket filled with water was placed at a head of 1 m. The water was allowed to flow through emitters located at 30 cm intervals along the lateral lines laid at the land slope of 2%. Two lengths of PVC tubes 11 m long, 1 mm thick and internal diameters 16 mm, Micro-tubes 5 cm long and internal diameter 1.2 mm, were used. The discharge from each emitter was determined through volumetric measurements. The system was then evaluated using the Christiansen’s method and the Merriam and Keller’s method and assessed using ASAE standards 1996(a) and 1996(b) performance rating. 22 sampled emitters evaluated from the lateral line showed total energy drop of 2.5 x 10-5 m, flow variation (FV) of 8%, coefficient of variation (CV) of emitter discharge of 0.02, uniformity coefficient (UC) of 97% and emission uniformity (EU) of 73%. The results show that the system is efficient and can be used by farmers to meet the demands for vegetables in the dry season.

This article deals with the issue of solar-powered irrigation, specifically, by connecting a solar power source to a drip irrigation system. Thanks to an independent energy source the irrigation system is able to work anywhere. In addition to energy independence, thanks to the drip mode of irrigation, another benefit is water saving, which is up to 70% compared to conventional irrigation. The simplicity of this system allows use both in small gardens and in agriculture. Another advantage of the system is its expandability with various sensors (e.g. soil moisture monitoring), which will help with more efficient management of watering.


In the agriculture field, the method of irrigation and its proper usage is more important and it is well known that a very economical and efficient method is drip irrigation. The continuous monitoring of the soil and weather condition has to be done by the farmer in favour of growth of crops in conventional drip irrigation system. In this proposed system, the soil and weather condition of the field are monitored by the moisture as well as temperature sensor. The values from the temperature and moisture sensors are sensed and the signal is sent to the Arduino IDE controller which is powered by solar energy and thus the present values are compared with predefined values. According to value of the temperature and moisture, the crops can be supplied with the required amount of water. In the liquid crystal display, the sensed values of the temperature and moisture will be displayed and the user can receive the data through the GSM module.

Abstract An experiment was carried out in Al-Rifai District - Dhi Qar Governorate, to study the effect of the distance between drippers and their discharge on friction losses, coefficient of variation, and emission consistency of the drip irrigation system. Spiral drippers with a design discharge of 4 and 8 L.hr"1. While the emitters were installed at distances of 20, 40, 60 (cm). The actual discharge of the droplets was measured and the friction losses, emission consistency coefficient, and discharge variance ratio were calculated. The results showed that the distance between the emitters 60 cm gave the lowest percentage of friction losses, which amounted to 0.165, 0.204 (m) for drippers with design drainage of 4, 8 L.hr-1. The best values of the emission consistency coefficient and the variance ratio in the emitters discharge were 95.44 and 28.41% when using the 8L.hr-1 and the distance between the emitters is 60 cm, respectively.
