Influence of Soil Moisture and Added N on P Uptake

Abstract

The influence of soil moisture regimes, doses of added N and their interaction on the content and uptake of P by finger millet was investigated under pot and field conditions in red and black soils of Tamil Nadu with the variety CO. 10 as test crop at Tamil Nadu Agri- cultural University, Coimbatore. The P content of plants was in general not affected by the coil moisture regimes. Increased N application decreased the same. Plants in red soil con- tained higher P than those in black soil. P uptake was higher at higher levels of moisture and added N due to increased dry matter yield. The P uptake was maximum in red soils.
