Abstract
An investigation was undertaken to study the effect of drip and surface irrigation methods on Radish from Febrauary 2012 to March 2012 at New Orchard of Main Agricultural Research Station, UAS Raichur. The objective was to work out the water requirement of Radish and to compare the performance of growth parameter, yield, irrigation efficiencies and economics of drip and furrow irrigation (60, 80, 100 and 120 % ET)
The water saved in drip irrigation over furrow irrigation was found to be 50.47% 36.74%, 223.00% and 9.27% for 60%, 80%, 100% and 120% ET respectively. The response of Radish to different drip irrigation levels in terms plant height, number of leaves and leaf width were significantly superior in respect of 80 per cent and 100 per cent ET level. The Radish under different irrigation treatments except 60 per cent ET level performed very well in terms of average root weight and root diameter. The highest root yield of 11.07 tha-1 was obtained in 80 per cent ET level which was closely followed by 100 per cent ET level (12.16 tha-1).
The application and field water use efficiencies were found to be higher with drip irrigation treatments as compared to furrow irrigation. All the drip irrigation treatments recorded higher benefit: cost ratio (5.10 to 7.08). The furrow irrigation produced a benefit: cost ratio of 4.76. The general trend considering the different parameters tested suggests that 80 per cent ET level can be used to achieve higher yield of Radish in sand loam soils, under semi arid conditions.
