Abstract: Drip irrigation, one of the micro irrigation methods, is an efficient method of providing irrigation water directly into soil at the root zone of plants at very low rates (2-20 litres/hour) from a system of small diameter plastic pipes fitted with emitters or drippers. A few low cost automation systems were developed and evaluated their performance with drip irrigation on sweet corn on the sandy soils of College of Agricultural Engineering, Bapatla. It was observed that single row drip irrigation showed better results compared to flood irrigation and paired row drip irrigation. The results indicated that the amount of water applied in single row and paired row drip irrigation systems is less compared to flood irrigation. The plant height and root depth are observed to be more in soil moisture sensor based irrigation with single row spacing compared to paired row spacing and flood irrigation.
