The study was conducted at the Agricultural Research Station, Gangavati, University of Agricultural Sciences, Gangavathi in northern Karnataka, India during Rabi/summer, 2007-08 and 2008-09 with beetischolar_main (Beta vulgaris) as the test crop. Under the drip irrigation, the soil moisture content was the highest and maintained almost steadily near the field capacity throughout the cropping period at all distances away from the dripper. The maximum moisture content near the dripper was reduced to the extent of 15 and 19 per cent at a distance of 60 cm away horizontally and vertically downwards, respectively, from the dripper during 2007-08 in case of drip irrigation at 0.6 ET in salinity level-I, against16 and 20 per cent during 2008-09. The soil moisture content at particular distance from the point of application increased with increase in depth of applied water and it decreased with distance from the point of application (R2= 0.83 to 0.92). The maximum water use efficiency of 6.74 and 6.23 kg m-3 was achieved in drip irrigation at 0.6 ET under salinity level-I and the lowest water use efficiency of 2.78 and 2.40 kg m-3 was recorded in drip irrigation at 1.4 ETin salinity level-III during 2007-08 and 2008-09, respectively. Among the surface irrigation levels, the highest water use efficiency of 4.25 kg m-3 at 1.0 ET and 3.32 kg m-3 in 0.8 ET was recorded in salinity level-I during 2007-08 and 2008-09, respectively.Keywords

The experiments were conducted with beetischolar_main (Beta vulgaris) as test crop in saline vertisols of Tungabhadra Project command area in Northern Karnataka, India during 2007-'08 and 2008-'09 in strip plot design with three soil salinity levels (Electrical conductivity, EC - 1.3, 2.7 and 4.3 dS m-1) in main plots and five drip irrigation levels (Evapotranspiration , ET- 0.6, 0.8, 1.0, 1.2 and 1.4 ) with three surface irrigation levels (0.8, 1.0 and 1.2 ET) in sub-plots adopting three replications. There was significant difference in tuber yield owing to different irrigation regimes by various levels of drip and surface irrigation methods. The highest tuber yield of 19.43 t ha-1 was recorded by drip irrigation at 1.2 ET followed by drip irrigation at 1.4 ET (18.28 t ha-1) as against the lowest tuber yield of 9.98 t ha-1 in surface irrigation scheduled at 0.8 ET during 2007-'08. Similarly, the highest tuber yield of 18.91 t ha-1 in drip irrigation at 1.2 ET and the least yield of 9.6 t ha-1 in the surface irrigation scheduled at 0.8 ET were registered during 2008-'09. The different levels of salinity had marked influence on tuber yield during both the years. Significantly the highest tuber yield of 18.23 t ha-1 and the lowest tuber yield of 11.0 t ha-1 were recorded, respectively in salinity levels- I and III during 2007-'08. Similarly, during 2008-'09 significantly the maximum tuber yield of 17.89 t ha-1 in salinity level-I and the least of 10.5 t ha-1 in salinity level-III were observed.Keywords

A study was conducted at the Agricultural Research Station, Gangavati, in northern Karnataka, India during Rabi/summer, 2007-'08 and 2008-'09 with beetischolar_main (Beta vulgaris) as the test crop in saline vertisol. During both the year and irrespective of the soil salinity levels slightly higher nitrogen was observed at 15 cm away from the dripper point compared to either at the dripper point or distances beyond 15 cm from the dripper point. The magnitude of available nutrients decreased vertically with increase in soil depth. The drip irrigation scheduled at 1.2 ET resulted in the maximum tuber yields of 19.43 and 18.91 t ha-1 during 2007-'08 and 2008-'09, respectively. Among the salinity levels, the highest tuber yield of 18.23 and 17.89 t ha-1 were recorded in salinity level-I, respectively. Whereas among the surface irrigation levels, irrigation at 1.2 ET recorded the highest tuber yields of 12.2 and 11.84 t ha-1, respectively.Keywords
