Description The present study entitled “Effect of nitrogen levels and plant spacing on yield of bottle gourd cultivars”
was carried out at the Research Farm and Laboratory of Department of Vegetable Science, CCS Haryana
Agricultural University, Hisar during the rainy season, 2008. The experiment was laid out in a split plot design
with three replications having four levels of nitrogen (50 kg/ha, 62.5 kg/ha, 75 kg /ha, 87.5 kg/ha in main plots),
two plant spacing (60 cm and 75 cm) and two cultivars (variety GH-22 and hybrid HBGH-35) in sub plots, thus
making a total of sixteen treatment combinations. The plot size per treatment was 15 m2 (2 raised beds of 2.5×3m).
The analysis of variance revealed that the differences between nitrogen levels were found highly significant
for all the characters except fruit length, fruit diameter and early fruit yield per vine, where the differences were
only significant. Differences between plant spacing were highly significant for all the characters except days to
first female flower appearance, fruit length, vine length, average fruit weight and fruit yield per vine whereas, the
difference in branches per vine was only significant. The differences between cultivars were highly significant for
all the characters except fruit length, however, fruit diameter and early fruit yield per vine were only significant.
All interactions were not significant for all the characters.
First female flower appeared earliest and at lowest node along with first fruit picking with 50 kg nitrogen/ha
and 60 cm plant spacing. Maximum fruit length ,fruit diameter, vine length, average fruit weight, fruiting period
and number of fruits per vine were recorded with 75 kg nitrogen/ha and 75 cm plant spacing in both the variety
and hybrid. Maximum branches per vine, early and fruit yield per vine and dry matter content of fruit were
recorded with 87.5 kg nitrogen/ha and 75 cm plant spacing in both the cultivars. The maximum total fruit yield
(q/ha) was harvested from 87.5 kg nitrogen/ha with 60 cm plant spacing in both the variety GH-22 and hybrid
HBGH-35. The treatment with 87.5 kg nitrogen/ha and 60 cm plant spacing both in hybrid and variety resulted the
highest net returns and fetched 21.53% and 19.13% increase in the net returns over recommended packages.
