Summary, etc. A study on "Integration of nutritional inputs for improving nee
productivity in laterite soils" was taken up during 2001-2003 at the College of
Horticulture, Vellanikkara The experiment consisted of 17 treatments
including two sources of organic manure and two levels of nutrition with
combinations of lime and silica to develop a cost effective, high yield and
sustainable production technology for rice by identifying the components of
good management.
The treatment .receiving poultry manure with 90 kg ha" of fertilizer N
and 500 kg ha" of silica recorded the maximum height productive tillers,
•number of spikelets per panicle and thousand grain weight which
. contributed to the maximum grain yield 0[7004 kg ha". An increase in 1680
kg grain yield and 1087 kg straw yield than the package of practices
recommendation of Kerala Agricultural University appear to be due to the
application of Silica, substitution of cow dung by the poultry manure and
increased dose of N with an organic: inorganic ratio of 1 :2.25, increased
dose ofK and reduced dose ofP.
Cow dung contains Fe, Zn and Cu in toxic levels to rice. Poultry manure
has the content of these elements in far less quantities but has higher Ca content
.
which helps in reducing the uptake of unfavourable elements by the rice plants.
Increase in'the level of K application @120 kg ha' has recorded 1387 kg
ha" more grain than the present recommendation of 35 kg ha" and the uptake
of K by the plants are far above the applied levels. This suggests that the
present recommendation of35 kg ha' ofK has to be enhanced up to 120 kg ha"
to prevent the soil degradation. It is also seen that the rice plants absorb only
around 20 kg P and hence the P recommendation can be reduced from 35 kg to
20 kg ha".

There was no apparent effect when lime and silica were applied together
but individually they could improve the yield. The number of weeds and the
incidence of pests and disease were less in thetreatment plots, which revealed
the influence of soil ameliorants in impa~ing resistance in the rice pants.
TIle. results of the present study indicate that the failure of rice plants to
respond to higher doses of fertilizer N, appears to be because of the
unfavourable organic: inorganic' ratio. A ratio of 1 :2.25 was found to be
beneficial to nullity the unfavourable chemical effects of fertilizer N.
