Summary, etc.	A pot culture experiment on the "Influence of phosphorus on absorption <br/>and dynamics of nutrients in rice" was conducted during December 2002 to April <br/>2003 at the Radiotracer Laboratory, College of Horticulture, Kerala Agricultural <br/>University, Vellanikkara. <br/>The distribution pattern, content-effectiveness relations of phosphorus on <br/>rice productivity in relation to soil types, nutritional levels and the role of organics <br/>were investigated in the present study <br/>Plant height, tiller number, productive tillers,filled spikelets per <br/>panicle,grain and straw yield showed significant increase in kole soil treated with <br/>90:45:45 kgha' NPK along with Pongamia leaves @ 5 tha' (TII). <br/>Chlorophyll 'a' and total chlorophyll were highest in Tll having kole soil <br/>treated with 90:45:45 kgha' NPK along with Pongamia leaves @5 tha-I at panicle <br/>initiation and at 50 per cent flowering. A favourable cell sap pH was also noticed <br/>inTll_ <br/>TII gave highest plant content of N in both laterite and kole soil. P and K <br/>contents were also more in treatments having inorganics with Pongamia. Iron <br/>content of rice plants decreased with advancement in the stages of growth. <br/>Percent phosphorus derive~ from fertilizer (%Pdff) had highest value at <br/>maximum tillering and thereafter it decreased. %Pdff was increased with <br/>increasing levels of Phosphor~ls application. When the applications of inorganics <br/>with and without organics are compared in laterite and kole soil, application of <br/>single super phosphate with organics always gave highest %Pdff than with single <br/>super phosphate alone. Laterite soil treated with 90: 67.5: 135 kgha' NPK along <br/>with Pongamia leaves @ 5 tha' (Tg) obtained 10.68 % Pdff and the- same <br/>treatment in kole soil had 12.96% of %Pdff at harvest. <br/> <br/>%Pdfs was low at maximum tillering and thereafter increased up to harvest. <br/>At maximum tillering, laterite soil treated with 90:45:45 kgha' NPK without <br/>organics (T1) gave highest %Pdfs of 93.45% and the kole soil treated with <br/>90:22.5:90 kgha' NPK without organics (T13) gave highest %Pdfs of 93.51 % ,At <br/>50% flowering and at harvest in both soils treated with 90:22.5:90 kgha' ofNPK <br/>with or witnout organics recorded highest %Pdfs. Per cent uptake of applied P <br/>fertilizer by the plant also had an increasing trend from maximum tillering to <br/>harvest. But it was decreasing with respect to increase in levels of phosphorus <br/>from 22.5 kghalto 67,5 kgha'. <br/>Laterite soil treated with 90:67,5:135 kgha' of NPK along with <br/>Pongamia leaves @ 5 tha-I (Ts) registered highest concentration of available P of <br/>16,8 rngkg' followed by the same treatment in kole soil with 16.7 mgkg". <br/>A vailable iron content of soil after harvest was more in treatments having <br/>Pongamia in laterite soil while it was more with rice straw applied treatments in <br/>kole soil <br/>The present study indicate that organics-Pongamia and rice straw in <br/>conjunction with inorganics enable consistent supply of phosphorus for achieving <br/>enhanced grain and straw yield in both late rite and kole soil.Though Pongamia <br/>along with inorganics is an ideal fertilizer schedule for rice crop in terms of yield. <br/>when the cost of incorporation of Pongamia is considered, rice straw along with <br/>inorganics is more profitable and convenient. <br/><br/>
