Pineapple ( Ananas comosus (L.) merr.) predominantly grown in Kerala, Karnataka, West Bengal, Bihar and north-eastern regions where radiation energy is abundant. For long time, wider spacing was adopted leading to lower productivity and higher cost of production ( Singh and Singh, 1974; Chanda et al., 1975; Dass et al., 1978) as total dry matter production in pineapple is proportional to the amount of radiation intercepted. Planning system and optimization of plant density is aimed to achieve high assimilated production for its conversion into economic yield. The plant density designed to optimize light interception plays a key role in achieving high productivity.
