Description Not Available
A series of long-term simulations were carried
out to investigate alternative management practices to
increase grain yields of soybean and wheat by optimizing
sowing dates, nitrogen (N) and water requirements, along
with complimenting farmyard manure (FYM) as a N source
in the soybean–wheat cropping system of Madhya Pradesh.
The APSIM simulation study showed that the mean soybean
yield ranged from 1.0 to 1.6 t ha-1 for the different
dates of sowing. The average wheat grain yield was
3.2–3.9 t ha-1, whereas, the crop sown on 15 November
gave the highest yield. In this region, there is a potential to
increase soybean and wheat yields by 0.6 and 2.2 t ha-1,
respectively. Among the various irrigation practices simulated,
five irrigations of 60 mm at 20 days interval was
the best option for wheat. Application of 16 t FYM ha-1 to
soybean produced 50 % higher wheat yield than the same
amount of FYM applied to wheat. The wheat yield
obtained from inorganic application of N was at par with
that obtained from the application of integrated and organic
sources. However, the amount of N loss from the integrated
use of fertilizer N was lower than that from the current
recommended practice for the region. Application of FYM
alone or in combination with inorganic fertilizer maintained
higher soil organic carbon concentration as compared
to the application of inorganic fertilizer alone. Thus,
the model provided a mean of evaluating alternative crop N
and water management options for effectively managing
the soybean–wheat cropping system.
