Although bottle gourd (Lagenaria siceraria L.) is an
important vegetable crop in rural communities in the arid Mediterranean
region, still no sufficient information regarding its cultivation practices is
available. A two-year field experiment (2019 and 2020) was carried out to
assess the effects of planting density and irrigation method on bottle gourd
yield, following a split-plot experimental design with two planting
densities of about 11 111 and 5555 plant ha–1
, and two irrigation methods
(drip irrigation and wide-spaced furrows as surface irrigation), with three
replicates. Significant effects of both factors on bottle gourd fruit
characteristics, dry matter, fresh marketable yield, water productivity
(WP), and irrigation water use efficiency (IWUE) were found. Seasonal
evapotranspiration and irrigation water amounts were considerably
reduced by about 20% under drip irrigation as compared with surface
irrigation. Moreover, dry matter, fresh marketable yield, WP, and IWUE
were doubled. Combining drip irrigation with the lower planting density
was the most favourable practice for the bottle gourd crop productivity
under the studied context. These findings of high fresh marketable yield
and water productivity suggest that bottle gourd crop could be considered
as an alternative crop for food security and economic prosperity of rural
communities. Adopting drip irrigation can effectively address the water
shortage issue and sustain crop production in the arid Mediterranean area.
