 ABSTRACT

Field experiment was conducted at Experimental Farm, Annamalai University during the season of January – April 2013 to determine the efficacy of different organic sources in combination with chemical fertilizer on growth and yield attributes of sunflower. The field experiment was raised in a randomized block design with replicated thrice and consists of ten treatments with 5 ´ 4 m of plot size. Application of recommended dose of fertilizer (60:90:60 kg of NPK ha-1) along with vermicompost @ 5 t ha-1 and combination with foliar application of MnSO4 @ 0.5% on 40 and
60 DAS recorded the highest plant height, leaf area index and dry matter production under growth attributes. The yield attributes of total number of seeds capitulum-1, number of filled seeds capitulum-1 and seed yield (kg ha-1) has recorded with highest values in above said treatment combination.

Key words: Poultry manure, Foliar fertilization, Chemical fertilizer, Growth and
Yield attributes.
