Comparative performance of organic manures and inorganic fertilizer on the growth and flower yield of Gladiolus

The experiment was conducted at the Indo-Italian Fruit Development Project, Dhakrani, Dehradun, India during 2001–2002 to study the performance of organic manures and inorganic fertilizer on the growth and flower yield of gladiolus (var. Jester Gold). All the treatments of organic and inorganic supplements have showed the significant response on vegetative growth, flower yield, corm and cormels production over control treatment. Among the 14 treatments, T₉ treatment (50 kg N from urea and PM) increased the plant height by 64%, 26% and 23% and flower yield by 52%, 39% and 38% as compared to T₀, T₄ (100 kg N through poultry manure) and T₅ (100 kg N through urea) treatments, respectively. The corm and cormels weight was also enhanced by 126%, 68% & 56% and 129%, 66%, 61% under T₉ treatment over to control (without N), T₄ and T₅ treatments, respectively.
