Abstract

A field experiment was carried out from early July to end of March during the years 2019-21 at Model Floriculture Centre, G.B. Pant University of Agriculture and Technology, Pantnagar to study the effect of NPK through drip fertigation on vegetative and floral growth of chrysanthemum with five treatment combination viz, T1-100:150:100 kg NPK/ha/year, T2-100:150:100 kg NPK/ha/year, T3-100:150:100 kg NPK/ha/year, T4-75:112.5:75 kg NPK/ha/year, T5-75:112.5:75 kg NPK/ha/year at vegetative, bud and flowering stage. The treatment T3 (NPK @ 100:150:100 kg/ha/year) recorded maximum plant height, number of primary branches, stem diameter, days to first flower appearance, number of buds per plant and flower yield per plant over rest of the treatments during both the years of investigation. The results suggested that application of NPK @ 100:150:100 kg/ha/year through drip fertigation helps to achieve higher vegetative and floral growth of chrysanthemum under Tarai region of Uttarakhand.

Keywords

NPK, fertigation, chrysanthemum, vegetative traits, floral attributes.

Conclusion

On the basis of results obtained in present investigation, it can be concluded that the application of NPK @ 100:150:100 kg /ha/year, at vegetative, bud and flowering stage through drip fertigation may positively accelerate the vegetative and reproductive stage as well as for commercial cultivation of chrysanthemum.
