Charcoal is a carbon-rich organic matter, which serves as a
soil conditioner when applied to agricultural fields. When used in
combination with nitrogen fertilizers, it has a synergistic effect that boosts
plant growth. However, charcoal application alone or in combination with
nitrogen fertilizer on vegetable crops is not fully understood. Therefore, a
pots experiment was carried out to investigate the effect of charcoal and
nitrogen levels on the growth and yield of broccoli. The variety of broccoli
used was Centauro. The experiment was laid out in a two-factor
Completely Randomized Design with five replications during the winter
season of 2019–2020 at Sundarbazar, Lamjung, Nepal. Treatments
consisted of four levels of charcoal (0%, 2.5%, 5%, and 7.5% per weight
of soil) and three levels of nitrogen (0, 187.5 and 375 kg N ha–1). Results
revealed that increasing nitrogen levels from 0 to 375 kg N ha–1
significantly increased the number of leaves, leaf area, head diameter, head
weight and aboveground biomass. The maximum head weight per plant
(258.77 g) was found by applying a nitrogen level of 375 kg N ha–1 and
the lowest value at 0 kg N ha–1. The application of increasing levels of
charcoal significantly improved root length, leaf area and head diameter.
It was concluded from the results that the optimum nitrogen level for
broccoli production could be 375 kg N ha–1.
