ABSTRACT
An experiment was conducted to study the effect of organic and inorganic fertilizers on plant height, plant spread and flower diameter of Gaillardia (Gaillardia pulchella). In Gaillardia the plant maximum height was recorded in the plot treated with 100 per cent recommended dose of NPK + press mud at 10 tones ha-1 followed by 75 per cent recommended dose of NPK + press mud at 10 t ha-1 at 45 days and 75 per cent recommended dose of NPK + press mud at 5 tones ha-1 at 15, 30 and 60 days. Highest plant spread was obtained at 30 and 45 days after planting in the treatments which involved 100 per cent recommended dose of NPK + press mud at 10 t ha-1 and at 60 days no significant differences were recorded. The combination of recommended dose of NPK + press mud at 10 t ha-1 produced maximum diameter of flower.
