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

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.

It is suitable for potted plants, bedding, edging, garland making, religious offerings and also for making different products. It has important role in preparation of garlands, bouquets and for floral decoration at the time of marriages and other ceremonies. In India, marigold occupies an area of 55.89 thousand hectare with the production of 511.31 thousand MT and Rajasthan, occupies an area of 1079 hectare with the production of 1039 tonnes ( Anonymous 2013-14). Besides having ornamental, medicinal, industrial uses, it has additional use in controlling the soil nematodes. All varieties of marigold are resistant to Meloidogyne incognita and can be used for control of Meloidogyne incognita in highly infected areas (Warden and Windrich, 1974). Phosphorus is also a major nutrient required by the crops. It is indispensable constituent of nucleic acid, phospholipids and several enzymes. The most essential function of phosphorus in a plant is energy storage and transfer for proper metabolism. A good supply of phosphorus is associated with increased root growth and early maturity of crop besides disease resistance in plants (Tisdale et al., 1995). About 98 per cent soil of cultivated area in India need phosphorus fertilization for good harvest (Luthra et al., 1983). Application of phosphorus not only increases the crop yield but also improves the quality. These products are helpful in minimizing the environmental hazards and increase of Soil fertility. Vermicompost is an excellent soil conditioning agent. Incorporation of vermicompost in soil improves the texture, structure, permeability and water holding Capacity of soil. Materials and Methods The field experiment conducted at School of Agriculture and Environmental Sciences in Shobhit University Gangoh Saharanpur U.P. in India during 2016-2017 to evaluate the performance of marigold var Pusa Basanti Gainda to Nitrogen, Phosphorus and Vermicompost on growth and flower yield. The experimental soil was sandy loamy having low available with neutral. The experiment laid out in randomized complete block design with three replications. Eight treatments consisted of vermicompost@5t/ha, nitrogen @120 kg/ha, and phosphorus 80 kg/ha were compared with control plot (lal singh et al., 2015). Seeds were sown in the month of January February and transplanted in main field February march on each plot size was 1.2 m x 1.2 m with a spacing of 40x30 cm (Gaurav Sharma et. al 2016 and G. S. Saini et. Al). Observations were recorded on growth and yield characters with the help of meter scale and vernier callipers and top balance respectively. The different organic manure and fertilizer treatments tried were the field experiment conducted at School of Agriculture and Environmental Sciences in Shobhit University Gangoh Saharanpur (U.P) India; during 2017-2018 to find out the performance of marigold T1 No manure control T2 Vermicompost @ 5 t ha-1 T3 Nitrogen @ 120 kg ha-1 T4 Phosphorus 80 kg ha-1 T5 Vermicompost @ 5 t ha-1 + Nitrogen @ 120 kg ha-1 T6 Vermicompost @ 5 t ha-1 + Phosphorus @ 80 kg ha-1 Vikas Kumar et al, International Journal of Advances in Agricultural Science and Technology, Vol.6 Issue.4, April2019, pg. 1-5 ISSN: 2348-1358 Impact Factor: 6.057 NAAS Rating: 3.77 © 2019, IJAAST All Rights Reserved, www.ijaast.com 3 T7 Nitrogen @ 120 kg ha-1+ Phosphorus @ 80 kg ha-1 T8 Vermicompost @ 5 t ha-1 + Phosphorus @ 80 kg ha-1+ Nitrogen @ 120 kg ha-1 Results and Discussion
