A field study was carried out during early Ahu/Boro season in the year 2016 at Konwargaon village of Morigaon district of Assam funded by AICRP on Water Management under the supervision of Krishi Vigyan Kendra, Morigaon, Assam to evaluate the effectiveness of shallow tube well irrigation with two improved rice varieties (Luit and Dishang) and one traditional variety (Soru Guni) among 15 numbers of farmers covering an area of 2 ha. The growth and yield attributing characters of Dishang varieties were found to be better over the other two tested varieties. The water productivity was recorded highest in Dishang (5.3 kg per mm). The highest grain yield was obtained from variety Dishang (5.42 t/ha) followed by Luit (3.50 t/ha). The maximum net return (Rs. 81300.00/ha) and B:C (3.19) were recorded from Dishang variety when irrigated up to 5 cm at 3 days after disappearance of ponded water (DADPW). The resultant effect has shown that effective water management practices along with use of suitable variety help in improving the yield per drop of water used and can double the income of farmers.
