Use of poor quality water for agriculture production requires appropriate management strategies such as leaching of excessive salts, selection of salt tolerant crops, frequent application of water etc. Thus a field experiment was conducted at C.C.S. Haryana Agricultural University, Hisar to study the salt dynamics in soil under drip irrigation system on cabbage crop and to investigate the effect of frequency and salinity levels of irrigation water on cabbage. Two irrigation frequency: daily (F1) and alternate day (F2) irrigation and five salinity levels of irrigation water: canal water (S1), ECiw3 (S2), 6 (S3), 9 (S4) and 12 (S5) dS/m treatments were considered in the experiment. With movement away from the plant (radial or vertically), salt concentration increased in the ischolar_mainzone. More electrical conductivity was observed at the wetting front of the ischolar_mainzone. In daily irrigation under saline water of ECiw 12 dS/m (F1S5), the ECe values after 90 days of transplantation was increased by 206.4, 222.1, 244.4 and 264.1% on comparing with initial values in 0-15, 15-30, 30-45 and 45-60 cm layers, respectively. In alternate day irrigation under saline water of 12 dS/m (F2S5), the ECe values after 90 days of transplantation was increased by 279.2, 262.7, 270.1 and 280.2% on comparing with initial values in 0-15, 15-30, 30-45 and 45-60 cm layers, respectively.

Abstract


Use of poor quality water for agriculture production requires appropriate management strategies such as leaching of excessive salts, selection of salt tolerant crops, frequent application of water etc. Thus a field experiment was conducted at C.C.S. Haryana Agricultural University, Hisar to study the salt dynamics in soil under drip irrigation system on cabbage crop and to investigate the effect of frequency and salinity levels of irrigation water on cabbage. Two irrigation frequency: daily (F1) and alternate day (F2) irrigation and five salinity levels of irrigation water: canal water (S1), ECiw3 (S2), 6 (S3), 9 (S4) and 12 (S5) dS/m treatments were considered in the experiment. With movement away from the plant (radial or vertically), salt concentration increased in the ischolar_mainzone. More electrical conductivity was observed at the wetting front of the ischolar_mainzone. In daily irrigation under saline water of ECiw 12 dS/m (F1S5), the ECe values after 90 days of transplantation was increased by 206.4, 222.1, 244.4 and 264.1% on comparing with initial values in 0-15, 15-30, 30-45 and 45-60 cm layers, respectively. In alternate day irrigation under saline water of 12 dS/m (F2S5), the ECe values after 90 days of transplantation was increased by 279.2, 262.7, 270.1 and 280.2% on comparing with initial values in 0-15, 15-30, 30-45 and 45-60 cm layers, respectively.
