Abstract

A Pot experiment to investigate “growth and flower quality production of marigold (Tagetes erecta L.) response to phosphorous fertilization” was conducted at the Ornamental Horticulture nursery Department of Horticulture, The University Agriculture Peshawar during 2014. The experiment was laid out Completely Randomized Design (CRD) with one factor repeated three times. In the experiment Marigold plants were fertilized with five level of phosphorous (0, 20, 40, 60, 80 kg ha-1). Result revealed that application of phosphorous significantly affected the various growth parameters except leaf area. Maximum plant height (38.30cm), number of branches plant-1 (32.00) and fresh flower weight (11.11gm) was recorded at phosphorous 60 kg ha-1, while highest stem diameter (0.69cm), more number of leaves plant-1 (335.67) and number of flower plant-1 (9.06) was recorded at phosphorous 80 kg ha-1. Phosphorus dose of 60 kg ha-1 and 80 kg ha-1 significantly affected study parameters of the tested crop of marigold. The experiment revealed that (60 and 80 kg ha-1) may for good quality flower production of Marigold flowers.
