Abstract

Chrysanthemum (Dendranthema grandiflora Tzvelev.) has earned tremendous popularity as a floral crop in Madhya Pradesh, particularly at Indore, Madhya Pradesh , India where it is being commercially cultivated as loose flowers in open field condition during June to January. However, lower production and poor quality of flowers were observed due to haphazard and unbalanced use of inorganic fertilizers and non use of biofertilizers. With the objectives to tackle the issue of low productivity and quality of flowers, dissemination of recommended technology was successfully attempted during 2015-16 and 2016-17. The technologies of balanced use of inorganic fertilizer with bioferetilizer (Azotobactor and PSB) were used as technical intervention. The collective effect of scientific intervention revealed an average yield of 113 quintal / ha, which is 14.76 % higher over farmer’s practice. Average net returns from recommended technology were observed to be of Rs. 1, 88,100 as compared to Rs. 1, 54,350 under farmer’s practice (control). Thus, an additional income of Rs 33,750 was realized through imparted technological intervention provided in demonstration plots. Cost-benefit ratio of recommended practice (2.25) was observed to be significantly higher over farmer’s practice (2.17). Enhanced economic benefit and favorable C: B proved the economic feasibility of the technological intervention and was convincing for the farmers, for further future adoption. At present scenario, organic fertilizers including bio fertilizers are becoming indispensable input to minimise our compulsion on synthetic fertilizers.

Highlights

Chrysanthemum (DendranthemagrandifloraTzvelev.) is commonly called as Guldawdi,saventi or Autumn Queen and belongs to the family Asteraceae
The imparted technological intervention was based on the information gathered through surveys, farmer’s interaction and problem solving field visit during the cropping period, which brought out that arbitrary and unbalanced use of inorganic fertilizers and no use of biofertilizers, were the causes of low yield of loose flowers of chrysanthemum.The technologies of balanced use of recommended levels of nitrogen, phosphorus and potash (150-200,200, 2005,15, 17,8 coupled with biofertilizer, namely Phosphorus solublizing bacteria (PSB) and azotobacter[1] were used as technical intervention during the course of on farm demonstration. 20 percent reduction in nitrogenous and phosphoric fertilizer was made under recommended practice
The flower yield enhancement over farmer’s practice, varied (14.42 to 15.10 %) from year to year, it was 14.76 per cent on mean basis .Year wise fluctuations in yield and cost of cultivation can be elucidated on the basis of difference in existing social, economical and microclimatic conditions of the particular village

Summary

Introduction

Chrysanthemum (DendranthemagrandifloraTzvelev.) is commonly called as Guldawdi,saventi or Autumn Queen and belongs to the family Asteraceae. Chrysanthemum has earned tremendous popularity as floral crop in Madhya Pradesh at Indore district where it is being commercially cultivated as loose flowers in about 95 hectare[2] in open field condition during June to January.
