Abstract: The present study was undertaken to investigate the effect of plant geometry and sowing windows on growth and yield of pearlmillet (Pennisetum americanum L.). The experiment was carried out at Agricultural College Farm, Bapatla during kharif, 2018, with 4 plant geometry (45x15 cm, 45x30 cm, 60x15 cm and 60x30 cm) and also with 3 dates of sowing (2^nd fortnight of July, 1^st fortnight of August and 2^nd fortnight of August). The results revealed that among the different plant geometry, the maximum plant height, days to 50% flowering and days to maturity were recorded under treatment 60× 30 cm but higher number of tillers m^-2, dry matter accumulation, grain yield, stover yield and harvest index were recorded with 45× 15 cm treatment. Among different dates of sowing, the highest plant height, number of tillers m^-2, dry matter accumulation, days to 50% flowering, days to maturity, grain yield, stover yield and harvest index were recorded with 2^nd Fortnight of Jul.
