Abstract


Field experiment framed in a Randomized Block Design was conducted to assess the impact of
polyethylene mulch on soil temperature and yield of drip irrigated bitter gourd during 2015-16
in the Department of Irrigation and Drainage Engineering Dr. PDKV, Akola. The soil temperature
at 15cm soil depth at 06:00 hrs was observed more than the ambient temperature, while at 14:00
hrs, it was less than ambient temperature, irrespective of irrigation scheduling treatments.
The soil temperature under black mulch was observed to be highest followed by silver mulch,
while temperature of soil without mulch cover was observed to be the lowest. Though average
ambient temperature varied from 13 to 32.10C, the soil temperature under mulch varied from
22.4 to 27.80C i.e. in optimal temperature range for bitter gourd production. Subsequently, the
crop yield was found maximum under black polyethylene mulch with irrigation scheduling at
80 per cent crop evapotranspiration through drip irrigation system followed by under silver
mulch with irrigation scheduling at 80 per cent ETc.
