The study analyses the response of onion to different irrigation levels with microsprinkler
irrigation system. The four treatments comprised different ratio of irrigation water (IW) to
cumulative pan evaporation (CPE) namely 0.60 (T1), 0.80 (T2), 1.0 (T3) and 1.20 (T4). Irrigation
had significant effect on growth parameters of onion and subsequently influenced the crop
yield. The best yields were recorded from T3 and T4, associated with the higher percentage of
bulbs having diameter greater than 45 mm. Protein content in bulbs was highest when
associated to T1, but the loss in marketable produce during the storage was also highest in
T1. Irrigation water use efficiency and water use efficiency both were highest in T2 and then
declined with the increase in irrigation. Hence, in water constraint situation, T2 would be the
most appropriate irrigation level for onion production with microsprinkler irrigation system.
Production functions of yield versus irrigation water applied and yield versus crop
evapotranspiration were found to be polynomial. The developed functions can be used as a
guide to yield potential allocation decision related to limited irrigation water.
