Effect of saline water and integrated approach based treatments on chemical properties of water and soil and growth and development of black gram

Abstract

The twelve treatments comprised in series of physical, cultural and biological methods were imposed on 2, 4 and 6.0 dS m-1saline water (SW)for assessing water EC and ions concentrations. Of which, two treatments viz.SW exposure to 0.44 T MFs (6 min) + incubation with Amla stem powder @ 6 g 6 hrs L-1 + five days incubation with C10 bacterial culture (BC)@ 4 ml L-1,and SW exposure to 0.44 T MFs (6 min) + incubation with Muringa seed powder @ 6 g 6 hrs L-1 + five days incubation with C10BC solution @ 4 ml L-1were carried out for assessing the treated SW effect on soil properties and growth and development of black gram (Vigna mungo) grown in saline and non-saline soils. The treatment efficiency decreased with increased salt content. The treatments of cultural and saline bacterial combinations, and integration of all approaches were equally effective.The integrated approach treatment reduced on an average 30.3 % EC, and 64.3% Ca2+, 51.6 % Mg2+, 24.9 % Na+, 26.5 % SO42- and 18 % Cl-ions concentration. The salt accumulation from saline water lowered for treatments and both the treatments were equally effective. As a whole, it reduced nearly 50-56 % salt accumulation, and >57% Ca2+, >44 % Mg2+, >36% Na+, >22 % SO42- and >13 % Cl- in both the soils. Improvement of plant growth parameters and eventually 13.4 % yield increase were achieved.
