Evaluation of Moisture Content of Soil at Different Stages of Plant Growth under Different Irrigation Treatments

Drip irrigation is artificial technique of providing water to the roots of the plant 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 soil water distribution pattern showed the highest water content near the drip line for all scheduling techniques.As increase in time of operation Wetting diameter and Penetration depth increased in relative to time. With comparison of different irrigation systems, the soil moisture content value of before irrigation and after irrigation is better in single row drip system.
