Description Tillage and surface management plays a crucial
role in sustainable management of soil and water resources.
Therefore the influence of various tillage practices and
straw mulching with rice straw @ 10 tonnes/ha on the soil
edaphological factors and hence on the growth and yield of
chickpea crop was studied in a rice-chickpea cropping system
at the Research farm, IGKV, during rabi 1994-95 with the
chickpea variety "J.G.-74". The crop was sown on 7th Nov'1994
and harvested on 20th March, 1995. Three tillage treatments
with and without rice straw mulch application and zero
tillage treatments were compared in R.B.D. with four
replications.
The different tillage treatments (Broadcasting of
chickpea seeds + cross ploughing + planking, Broadcasting of
chickpea seeds + cross ploughing + discing + planking and
ploughing + discing and planking followed by line sowing)
were found to have no significant differences between them in
respect of their performance whereas a significant difference
was obtained between the tillage treatments and the zero
tillage treatment. Grain yield, total dry matter yield and
•53
other yield attributing characters as well as the crop growth
were enhanced by the tillage treatments. Soil compaction was
more under zero tillage treatment than under the tillage
treatments, thus resulting in poor plant growth by
restricting the root penetration to the deeper soil layers
and the water movement to the roots, whereby resulting in a
low yield as compared to other tillage treatments. Thus
tillage treatments by providing a congenial physical
environment for the various activities of the plant growth,
proper aeration and water retention helped in resulting in a
good crop production as against zero tillage.
Rice straw mulching also showed a beneficial
effect on plant growth and yield. Mulching helped in
reducing the surface soil temperature where by preventing
excessive evaporation losses from the surface.
Thus it can be concluded that the treatment,
broadcasting of seeds followed by ploughing, discing and
planking together with mulching had more favourable effect on
the soil edaphological and physical properties as well as on
growth and yield of chickpea after transplanted rice, while
the treatment with poorest performance was found to be the
zero tillage (direct drilling of seeds between the standing
rows of rice straw).
