Abstract


An investigation on the influence of different irrigation regimes on the uptake of P by finger millet and its distribution in soil revealed that the treatment with most fre queut irrigation (IW/CPE ratio of 0.90 with 4 cm depth of water).resulted in the highest P content at the maximum tillering and flowering stages combined together and also the P concentration of grain and straw. The lowest P content was recorded with irriga- tion at IW/CPE ratio of 0,60 with 6 cm depth of water. Inigation at moderate inter- vals (IW/CPE ratio of 0.75 with 4 cm depth of water) resulted in the highest uptake of P by the ragi grain and straw and irrigations at the longest intervals IW/CPE ratio of 0.60 with 6 cm depth of wat-r) recorded the lowest uptake values. Values of available P in soil. after the crop uptake, was the highest with irrigations at the longest intervals and lowest in the treatment with irrigationis at the longest intervals (and lower in the treatment with irrigations at the shortest intervals. P content of soil decreased with an increase in soil depth and crop age.
