Effect of integrated nutrient management on economic yield of cut flower of China aster (Callistephus chinensis L. Nees)

Abstract

The present investigation entitled “Effect of integrated nutrient management on economic yield of cut flower of China Aster (Callistephus chinensis L. Nees)” was carried out at Main Experiment Station, Department of Horticulture, Narendra Deva University of Agriculture & Technology, Kumarganj, Faizabad, (U.P.) during the year 2015-16 to 2016-17. The experimental material i.e. China aster cv. Prince. The experiment was laid out in randomized block design with sixteen treatments comprising of PSB, Azotobacter and FYM alone or in combination with each other and variable doses of N, P and K in three replications. The experimental results have clearly showed that the application of recommended nitrogen, phosphorus and potassium can be saved with the application of vermicompost and dual inoculation of Azospirillum and PSB besides obtaining higher flower yield of china aster. Therefore, it may be concluded that the use of T15- Azo + PSB + VC + 50% RDF helped in realizing, higher quality of flower yield (216.49 q/ha in 2015-16 and 220.91 q/ha in 2016-17) and above all, in the C:B ratio (1.41 in 2015-16 and 1.45 in 2016-17) above all, in the production of china aster (Callistephus chinensis L. Nees) cv. Prince in eastern Uttar Pradesh.
