Abstract
Rice (Oryza sativa L.) is the staple crop in Bangladesh and different factors influence its productivity. Among these factors, desired number of plant spacing per unit area is important for higher yield attainment.Therefore, this study were undertaken to define the optimum plant geometry for getting the maximum yield. The experiment was conducted at Agronomy field, Sher-e-Bangla Agricultural University during December, 2011 to May, 2012 to study the growth and yield of Boro rice (BRRI dhan 50) as affected by planting geometry under System of Rice Intensification (SRI). Experiment comprised 5 level of plant spacing, viz. S1: 25 cm × 25 cm, S2: 30 cm × 30 cm, S3: 35 cm × 35 cm, S4: 40 cm × 40 cm and S5: 25 cm × 15 cm following Completely Randomized Block Design with three replication. Maximum dry matter (156.2 g/hill), number of tiller (44.0/hill), number of effective tiller (36.3/hill), number of filled grains (101.5/panicle), grain yield (6.9 t/ha), straw yield (5.9 t/ha), biological yield (12.7 t/ha) and harvest index (54.5%) was found from 40 x 40 cm plant spacing while minimum was observed from 25 x 25 cm of plant spacing in this study.
Key words: Oryza sativa, Planting geometry, Rice growth and yield
