Abstract:

An experiment was carried out during kharif, 2013 at College Farm, Rajendranagar, Hyderabad. with three plant densities  (1 seedling hill-1, 3 seedlings hill-1, 5 seedlings hill-1) as factor  one and four age of seedlings (15 days old seedlings, 25 days old seedlings, 35 days old seedlings, 45 days old seedlings) as factor two in randomized block design, replicated thrice. Experimental results showed 5 seedlings hill-1 was found to be significant to get more productive tillers (288) and grain yield (5817 kg ha-1) over 3 seedlings hill-1 and 1 seedling hill-1 due to more dry matter production (348, 793 and 1296 g m-2 ) at panicle initiation, heading and physiological maturity stages and dry matter partitioning as stem, leaf and grain (300, 242 and 754 g m-2) at physiological maturity stage respectively over 3 seedlings hill-1 and 1 seedling hill-1. Among different age of seedlings significantly more productive tillers and grain yield was obtained with 25 days old seedlings over 15, 30 and 45 days old seedlings with more dry matter at panicle initiation, heading and physiological maturity stages and dry matter partitioning as stem, leaf and grain (330, 261 and 824 g m-2) at physiological maturity
