Description A field experiment entitled “Long-term effect of FYM on physical properties of sandy loam
soil under pearl millet-wheat rotation” was conducted during the year 2012 at Soil Science Research
Farm of CCS Haryana Agricultural University, Hisar (India). The ongoing field experiment consisted
of 30 treatments combination, but for the present study only seven treatments as described herewere
taken : L0 Control: An absolute control without application of FYM and N in any of the season was
maintained as control; L1FYM ha-1 (15 t FYM ha-1 up to 2007-08 and 5 t FYM ha-1 from 2008-09
onward in rabiseason); L2FYM ha-1 (30 t FYM ha-1 up to 2007-08 and 10 t FYM ha-1 from 2008-09
onward in rabisaeson); L3 FYM ha-1 (45 t FYM ha-1 up to 2007-08 and 15 t FYM ha-1 from 2008-09
onward rabisaeson); L4FYM ha-1 (15 t FYM ha-1 up to 2007-08 and 5 t FYM ha-1 from 2008-09 onward
in kharifseason); L5 FYM ha-1 (30 t FYM ha-1 up to 2007-08 and 10 t FYM ha-1from 2008-09 onward in
kharifseason); L6FYM ha-1 (45 t FYM ha-1 up to 2007-08 and 15 t FYM ha-1 from 2008-09 onward
kharifseason)
[Note: Levels of FYM: 3 (15, 30, 45 t ha-1 till 2007-08) and( 5, 10, 15 t ha-1 from 2008-09 onward)
with 120 kg N ha-1. Mode of application was before wheat sowing (Winterrabiseason) and before pearl
millet sowing (Summer kharifseason)].
Long-term application of FYM, after 45 year cycle in pearl millet-wheat rotation improved
significantly the SOC content, bulk density, saturated hydraulic conductivity and infiltration rate as
compared to the control. Overall Bulk density decreased by 8.4% and 6.9% in rabi season and kharif
season, respectively over control. Maximum decrease in bulk density at 0-5, 5-10 and 10-15 cm in both
season were in L3 and L6treatments..Farmyard manure increased the infiltration rate by 24.1 and 20.4%
in rabiandkharifseason, respectively over the control. The mean weight diameter (MWD) of dry
aggregates was 3.6% higher when FYM was applied in rabi season as compared to that applied in
kharif season. Available water was 5.7% higher in FYM application during rabiseason than that
applied in kharif season. Similarly Farmyard manure significantly increased the maximum water
holding capacity of soil by 18.0% and 16.8% during rabiandkharif season over control. Rabi season
application had 1.5% higher maximum water holding capacity than kharif season FYM application.
Application of FYM in rabi season proved more beneficial in improving the soil physical properties as
compared to its kharif season application in pearl millet-wheat rotation.
