Abstract

An investigation was carried out to study the effect of nitrogen and phosphorus on growth, flowering and yield of cut chrysanthemum cv. Thai Chen Queen. The experiment was laid out in randomized block design (RBD) with factorial concept comprising of twelve treatment combinations with four levels of nitrogen, viz., 100 kg N/ha (N1), 150 kg N/ha (N2), 200 kg N/ha (N3) and 250 kg N/ha (N4) and three levels of phosphorus, viz., 50 kg P2O5/ha (P1), 75 kg P2O5/ha (P2) and 100 kg P2O5/ha (P3). The treatments were replicated four times. The results indicated that application of 200 kg N/ha (N3) to cut chrysanthemum was most effective to increase plant height whereas, plants receiving 150 kg N/ha significantly improved vegetative growth as well as quality and yield of flowers. Application of 75 kg P2O5/ha was found promising for growth, quality as well as yield parameters.

Highlights

Chrysanthemum (Chrysanthemum morifolium Ramat.) is a very popular commercial flower grown for cut flowers, loose flowers as well as pot plant all over the world
Growth Parameters Effect of Nitrogen The results revealed that application of 200 kg N/ha (N3) significantly improved plant height (45.32 cm) in cut chrysanthemum
The increase in plant height might be due to the fact that nitrogen is a constituent of protein which is essential for formation of protoplasm affecting the cell division and cell enlargement and better vegetative growth

Summary

Introduction

Chrysanthemum (Chrysanthemum morifolium Ramat.) is a very popular commercial flower grown for cut flowers, loose flowers as well as pot plant all over the world. It has been established that the nutrition plays an important role in improvement of vegetative growth and flower yield in chrysanthemum (Chezhiyan et al, 1986).[2] For obtaining good growth and quality flowers in cut chrysanthemum, application of nitrogen and phosphorus has been found very effective. Arriving at an optimum dose of nitrogen and phosphorus is expected to boost the flower production in cut chrysanthemum. Keeping these points in view, the present investigation entitled “Effect of nitrogen and phosphorus on flower yield and quality of cut chrysanthemum cv.
