An on-farm study was undertaken to determine the quality of underground water,
its effect on soil properties in the canal command areas, and impact of sodic soil
technologies i.e gypsum levels, green manuring, farm yard manure (FYM) and
deep tillage on yield of pearlmillet wheat crop sequence. Eighty six water samples
collected from canal command area of Tonk district of Rajasthan revealed that
22.1, 10.9, 5.8, 21.5, 29.8 and 9.9% water samples were under good, marginally
saline, saline, marginally alkali, alkali and highly alkali categories, respectively.
Most of these waters had dominance of sodium followed by calcium in cations and
chloride as major anion followed by bicarbonate and carbonates. After
interventions of sodic soil reclamation, wheat crop in rabi and pearlmillet in next kharif
season was grown. Maximum mean yields of 2.53 t ha grain and 11.0 t ha
straw of pearlmillet and 3.95 t ha grain and 4.74 t ha straw of wheat were
obtained with deep tillage in summer along with gypsum application@50% GR,
green manuring and FYM @ 10 t ha followed by GR-50% along with green
manuring and FYM @ 10 t ha . Treatment of deep tillage in summer along with
GR-50%, green manuring andFYM@10 t ha resulted in significant reduction of
EC, pH, ESP and bulk density, improvement in infiltration rate and availability of
N, P,Kand micronutrients.
