STUDY ON THE CONSERVATIVE USE OF WATER IN RICE CV SAKET-4 ON LIGHT TEXTURED SOIL

Abstract

This study consists of deciding a suitable water conservation technique in Rice grown on light textured soil. Since light textured soil has high seepage and , percolation rate the 60-80% water from rice is lost through it, thus increasing the water requirement and lowering the water use efficiency. The experiment was conducted during Kharif 1996 (June to October 1996) on the Demonstration- Farm of W.R.D.T.C. University of Roorkee, Roorkee, The experiment consisting of 4 treatments i.e. untreated , control (T1), vertical plastic barrier to a depth of 15 cm below ground (T2), vertical plastic barrier upto 15 cm below ground and one. side of the bund (T3), vertical plastic barrier upto 15 cm depth below ground and entire bund covered with the plastic barrier (T4) with 3 replication was laid down in Randomized block design. The plot was of 1,1 m x 3 m size rice cv Saket-4 was raised. The study consisted of water intake behaviour, physical property of soil, water use in nursery, water used in field preparation, daily water regime, periodical and cummulative ponding, plant height, tiller nos, total root depth, root intensity, yield and yield attributes in different treatments....
