PRODUCTIVITY AND GRAIN PROTEIN STATUS OF TRANSPLANTED AMAN RICE AS INFLUENCED BY THREE MAJOR AGRONOMIC PRACTICES UNDER SUBTROPICAL CONDITIONS

Abstract

The aim of this study was to investigate the yield and protein in grains of two high yielding varieties (HYV) transplanted Aman rice.The trial included two assortments viz.BRRI dhan62 and BRRI dhan66; three spacing's viz. 25 cm 15 cm, 20 cm 15 cm and 20 cm 10 cm; and four nitrogen doses viz.0, 60, 80 and 100 kg/ha.The study was conducted with randomized complete block design (RCBD) and the replication was three.At 70 DAS the tallest plant (126.40 cm), tillers/hill (11.00) and dry matter/hill (21.89 g) were delivered in association of BRRI dhan66 spacing (25 cm 15 cm) fertilizer 100 kg N/ha.The most noteworthy leaf area index (1.16) was recorded in BRRI dhan66 spacing (25 cm 15 cm) fertilizer 100 kg N/ha.The highest productive tillers/hill (7.33), longest panicle (23.74 cm), grains/panicle (129.3),weight of 1000-grain (26.50 g), grain (4.52 t/ha), straw (5.92 t/ha) yields and grain protein content (12.32%) were raised in BRRI dhan66 spacing (25 cm 15 cm) fertilizer 100 kg N/ha.The most elevated harvest index was found (47.72%) in BRRI dhan66 spacing (20 cm 10 cm) fertilizer 60 kg N/ha.BRRI dhan66 with 25 cm 15 cm planting and treated with 100 kg N/ha was the most promising interaction for enhancing yield and protein status of grains.
