Abstract
A pot experiment was conducted at the Department of SS & AC, Annamalai University during February-May, 2019 to find out the effect of different organic nutrient sources on yield attributes and yield of barnyard millet (Echinochloa frumentacea (Roxb.) Link). Millets are still the principal sources of energy, protein, vitamins and minerals for millions of poorest people. Coir pith has been found to an effective substitute for natural peat. Bone meal is a mixture of finely and coarsely ground animal bones and slaughter-house waste products. Panchagavya is an organic formulation with a blend of five products obtained from cow i.e. milk, ghee, curd, dung and urine. The treatments of the experiment were : T1 – Control, T2 –100% RDF, T3 – Coir pith compost @ 10 t ha-1, T4 – Bone meal powder @ 1 t ha-1, T5 – Panchagavya @ 3 % (Foliar spray), T6 –T3 + T4 , T7 – T4 + T5 , T8 – T3 + T5 and T9 – T3 + T4 + T5 . The design of the experiment was completely randomized design (CRD). Among the treatments, application of 100 % RDF (N: P2 O5 : K2 O @ 40:30:50 kg ha-1) (T2 ) recorded the highest number of productive tillers pot-1 of 6.54, ear head plant-1 (4.50), ear head length of 10.11, ear head weight of 30.37 g. grain yield of 166.15 g and straw yield of 306.15 g pot-1. The treatment T2 was on par with T9 .
