Performance evaluation of battery powered portable manual cotton picker was carried out on two subjects for three cotton varieties and was compared against manual method of picking. It is a hand operated machine and has a pair of chains with small sharp edged teeth and sprockets and is operated by a light weight 12 V battery. Cotton gets entangled with the chain and is collected and guided into the collection bag. Output capacity of cotton picker varied from 17.0–22.6 kg/day for BT and American cotton varieties. Picking efficiency of manual cotton picker was 68–91% and trash content varied from 1.8–6.1% for all three cotton varieties.
