ABSTRACT

 

An experiment was conducted during 2008-09 at the Department of Soil Science and Agricultural Chemistry, NMCA, NAU, Navsari to study the “Effect of Different Fertigation and Irrigation Water Salinity Levels on the Various Soil Properties of Navsari”. The experiment was laid out with Factorial CRD design with three repetition including two levels of fertilizers (F0: No fertilizer and F1: 150-50-50 NPK kg/ha), four type of emitters with differential discharge rate (D1: 1.2, D2: 2, D3: 3 and D4: 4 lph), four levels of EC (E1: 1.47, E2: 4, E3: 6 and E4: 8 dS/m). The result revealed that the chemical properties i.e. pH, EC and ESP were not significantly influenced due to fertilizer levels. Similarly, use of emitters with different discharge rates did not significantly altered the chemical properties of the soil studied in this experiment. However, the different levels of water salinity had significant effect on soil pH and ESP at 0-15 and 15-30 cm depth and EC at all the depths. Higher value of pH was recorded with the use of 8 EC water whereas, lower value was recorded in the treatment, use of 4EC water. The value of EC was found in order of E1234. Only D x E interaction was found significant on soil EC of 0-15 and 15-30 cm depths. Significantly higher value of EC in 0-15 cm was with D2xE4 and in 15-30 cm it was with D1xE4 and D2xE4. In upper depth it was at par with D1xE4 and in lower depth it was at par with D3xE4, D4xE4, D3xE3 and D4xE3. Physical properties did not influenced significantly due to the different treatments. The higher salinity level of water caused the soil pollution by depositing various salts, ions and its precipitates which may lead soil to make less productive.
