Technical Abstract: Poultry litter (PL) is used as a soil amendment for numerous crops, including rice. While it is known that rice growth is improved by PL, little study has been carried out to identify the specific growth parameters that are altered. We have identified a marked increase in the number of tillers (shoots) in plants grown in soil containing PL. The beneficial effect of PL has been ascribed to its nutrient composition. However, we have found that the tiller number of plants grown in PL along with complete fertilizer exceeds that of plants grown with fertilizer alone. Thus, PL appears to contain a factor in addition to any fertilizer components that improves rice growth by inducing tillering.
