Two experiments were conducted during 1987-88 and 1988-89 with 100, 200, 300, 400, 500 and 600 secds/m2 to study tillcring, dry matter production, ear growth and yield components of wheat. Number of tillers increased steadily upto 40 days after sowing and 100 sccds produced thc highest number of tillers (4/pIant). Dry matter production pcr plant was highest (8g/plant) with 100 seeds/m2. Thcrc was no significant diffcrcncc in the production or ear dry matter bctwccn 100 and 200, 300 and 400 and 500 and 600 sccds/m2. Number of grains/car was the highest with 300 sccds/m2 which was not significantly different with 400 sccds/m 2 for 1987-88 but for 1988-89 number of grains/ear was the highest with 100 sccds per m2. Grain yield was significantly higher with 400 secds/m2. Grain yield was significantly highcr with 400 sccds/m2 for both years but straw yield was the highest with 500 sccås/m2. There was significant correlation bctwccn grain yield and number of ears/m2 and between grain yield and number of grains/m2 suggesting possible yicld incrcasc with increased number of grains/m2.
