Direct effect of urea and vermicompost on growth and seed yield of bottle gourd and their residual effect on succeeding carrot

Abstract

A field experiment was conducted to ascertain the influence of urea and vermicompost on growth
and seed yield of bottle gourd and their residual effect on succeeding carrot crop at Agriculture
Research Station, Durgapura, Jaipur during 2004-05 and 2005-06. The recommended dose of nitrogen
(RDN) was supplied through urea and vermicompost in different combinations. It was found that
integrated use of nitrogen significantly influenced the growth, yield attributing characters, yield
and nutrient content in seed. 50% RDN through urea and 50% RDN through vermicompost was
found to be the most significant not vine length, number of primary branches, fruit length and
girth, number of fruits (2.99) per vine, number of seeds (464.3) per fruit and seed yield (1012.5 kg/
ha). After harvest of bottlegourd seed crop, carrot was sown on layout with recommended package
and practices. It revealed that 100% RDN through vermicompost recorded maximum root length,
root width and yield of succeeding carrot crop.
