The effect of planting date (February-May) on growth and flowering of P. tuberosa was investigated during 1995-97 in Bihar, India. Early and late planting produced plants with poor flower and spike yields. Planting bulbs on 7 March followed by 22 March produced plants with a high number of long leaves/clump, thick and big spikes, and a high number of florets and spikes/unit area.
