Effect of Vermicompost, Nitrogen and Phosphorus Growth and Flower Yield of African Marigold (Tagetes erecta L.)

Abstract

The results of field study conducted at School of Agriculture and Environmental Sciences,
Shobhit University, Gangoh, Saharanpur, U.P., India during 2016-2017 evaluated the
Performance of marigold var. Pusa Basanti Gainda to various manures and fertilizers levels.
The productivity and quality of flowers is greatly influenced by the quantity and source of
nutrients. The experiment were laid out in a randomized block design with three replications
and eight treatment combinations comprised of organic manure (Vermicompost) and NP
fertilizers. Application of vermicompost, phosphorus and nitrogen conjointly at a
recommended dose of 5000, 80 and 120 kg ha-1 respectively, was most effective in
enhancing the vegetative growth parameters, such as plant height, number of branches, plant
spread, as well as flower yield parameters viz. number of flowers, flower circumference,
plant height, fresh weight of flowers, flower yield, flowering duration, number of leave and
branches per plant etc as compared to that of control samples. Thus, use of inorganic
fertilizers in combination with organic manures resulted in excellent vegetative growth and
flower yield attributes in African marigold.
