Effect of Irrigation Frequency and Salinity Levels of Irrigation on Water Dynamics under Drip Irrigation in Cabbage (L. Brassica oleracea var. capitata)
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2018, Vol 7, Issue 7
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 CCS 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. In daily irrigation, on comparing the contours of Figures 3.1 to 3.5 for 30 days after transplanting, it was observed that the pattern of moisture content in the rootzone was almost same in all treatments. Whereas, contours for 90 days after transplanting, has shown more depletion in moisture content upto ECiw of 6 dS/m and thereafter, depletion was reduced which may be due to accumulation of salt in the rootzone. In alternate day irrigation, on comparing the contours of Figures 3.6 to 3.10 for 30 days after transplanting, it is observed that the pattern of moisture content in the rootzone is almost same in all treatments i.e. F2S1, F2S2, F2S3, F2S4 and F2S5. Whereas, contours for 90 days after transplanting has shown similar variation in the moisture content as in daily irrigation frequency. More depletion in moisture content upto ECiw of 6 dS/m and thereafter, depletion were reduced with increasing levels of ECiw
