Abstract

This study was conducted to evaluate the effect of plant number per hill (PNH) on growth and yield of foxtail millet in drained paddy fields. Crop growth, development, and yield in the field were examined for 2 years to assess the efficiency of proposed cropping system. The greatest culm length of 138 and 148 cm in the first and the second year, respectively, at the harvest stage was observed in plots with one plant per hill. The greatest culm diameter of 7.79 and 7.67 mm in the first and second year, respectively, was measured in plots with one plant per hill. The greatest tiller number of foxtail millet in plots with one plant per hill was 2.9 and 2.7 in the first and the second year, respectively. However, there was no significant difference between plots with four and five plant per hill. Among the measured yield components, the spike length and seed number per spike were one plant per hill in both years. The highest grain yield of foxtail millet ($324kg{\cdot}10a^{-1}$ and $333kg{\cdot}10a^{-1}$ in the first and second year, respectively) was obtained from plots with two plants por hill, followed by plots one, three, four, and five plants per hill.
