Effect of Nitrogen and Phosphorus fertilizers on growth of Zinnia ( Zinnia elegans Jacq.)

Abstract

Present investigation as carried out to investigate the “Effect of Nitrogen and Phosphorus fertilizers on growth of Zinnia (Zinnia elegans Jacq.) in summer season of 2016. The experiment was conducted at Main Experimental Station, Department of Horticulture, Narendra Deva University of Agriculture & Technology, Kumarganj, Faizabad. The experiment was laid out in Randomized Block Design in a factorial arrangement having two factors with nitrogen and phosphorus levels. The combination of four levels nitrogen (0, 50, 100, and 150kg/ha) and three levels of phosphorus (0, 100, and 200 kg/ha) comprising of 12 treatment combinations. The effects of treatment were studied on growth. The maximum, plant height, plant spread, number of branches, number of leaves per plant, were recorded with nitrogen levels 100 kg N/ha. The phosphorus is also influenced with increasing trend on plant spread, number of breaches, number of leaves per plant.
