Effect of nutrient management on growth, flowering and flower yield of tuberose (Polianthes tuberose L.) under Chhattisgarh plain condition

Abstract

The present investigation was conducted in the year 2016-17 at the Department of Floriculture and Landscape Architecture, IGKV, Raipur, Chhattisgarh for the effect of integrated nutrient management on growth, flowering and flower yield of tuberose. Ten treatment combinations of different fertilizer and organic manure nutrients were comprised with three replications. Result showed the significant result and the maximum plant height, leaf length, fresh weight, dry weight, number of florets spike-1, length of spike-1, length of rachis and flower yield were recorded under T9 (75% RDF + FYM @ 3.5 t ha-1 + Vermicompost @ 1.5 t ha-1 + Poultry manure @ 2 t ha-1) followed by T7 (50% RDF + FYM @10 t ha-1 + Poultry manure @ 2 t ha-1). The maximum number of leaves plant-1, and diameter of floret were found under T7 (50% RDF + FYM @ 10 t ha-1 + Poultry manure @2 t ha-1) whereas the weight of 100 florets was recorded maximum under T8(50% RDF + Vermicompost @ 5 t ha-1 + Poultry manure @ 2 t ha-1).
