Abstract
A field experiment was conducted during kharif 2018 at Research Farm, College of Agriculture, Kaul (Kaithal) to study the effect of planting geometry and nitrogen levels on growth and yield attributes of scented rice variety Pusa 1121. The experiment was conducted with three planting geometry in main plots and five nitrogen levels in sub plots using split plot design with four replications. Results showed that planting geometry did not have any significant effect on plant height even at all the growth stages. However, narrow planting geometry of 20 cm x 15 cm recorded significantly higher number of tillers m-2 (309) at peak tillering, dry matter accumulation and crop growth rate at various growth stages. The same planting geometry recorded significantly higher number of effective tillers m-2 (273), grain yield (4.4 t ha-1 ) and straw yield (5.9 t ha-1 ). Whereas, wider planting geometry of 30 cm x 20 cm recorded significantly higher number of grains per panicle (107). Test weight and harvest index did not show any significant difference among planting geometries. The treatment imposing with 120 kg N ha-1 was significantly superior to other treatments with regards to plant height, number of tillers m-2 (311), dry matter accumulation and crop growth rate at various growth stages. The same treatment also showed significantly superior response with regard to number of effective tillers m-2 (303), number of grains per panicle (115), test weight (25.8 g), grain yield (4.5 t ha-1 ) and straw yield (5.8 t ha-1).
