Response of spacing and nitrogen levels on growth and flowering of salvia (salvia splendens L.)

Abstract

A field experiment was conducted to ascertain the response of spacing and nitrogen levels on growth and flowering of Salvia (Salvia splendens L.) during the winter season in the year of 2016. It was observed that among the three different spacings viz; 30A— 20 cm, 30 A— 30 cm and 40 A— 30 cm, tried, wider spacing (30 A— 30 cm) its growing higher plant height, plant spread, number branches and number of leaves and also maximum number of florets per spike, number of spike, spike length and rachis length. Plant was also recorded wider spacing i.e. 30 A— 30cm. Among various nitrogen levels viz. 0, 60, 100 and 140 kg N/ha, maximum improvement in various growth and flower character were observed under 100 kg N/ha. Among interactions, the spacing of 30 A— 30 cm and application of 100 kg N/ha recorded maximum value of growth characters viz. plant height, plant spread, number of branches per plant and flower characters viz. Days required for spike initiation, number of spikes, number of florets per spikes, spike length and rachis length and the treatment was considered as superior treatment.
