Abstract

A field study was undertaken at Bangladesh Agricultural University, Mymensingh during the season November 2017 to April 2018 to evaluate the effects of plant × row spacings on yield and yield contributing traits of two Boro rice varieties. Two rice varieties viz., BINA dhan-10 and BRRI dhan28 were sown in five plant spacings viz. 25 cm × 15 cm, 25 cm × 25 cm, 30 cm × 30 cm, 35 cm × 35 cm, 40 cm × 40 cm in randomized completely block design with factorial fashion with three replications. Growth performances, yield contributing characters and yield were significantly influenced by varieties and plant spacings. The highest grain yield (8.75t ha-1), straw yield (11.56 t ha-1), biological yield (20.31 t ha-1) and harvest index (43.05 %) were obtained from the variety BINA dhan- 10 sown at planting spacing of25 cm × 15 cm. More number of total tillers hill-1(14.75) and number of effective tiller hill-1 (12.87) were recorded from the variety BINA dhan-10 sown at planting spacing 40 cm × 40 cm. Based on the present study it is suggested that BINA dhan-10 may be grown under 25 cm × 15 cm in order to get maximum grain yield for Boro rice cultivation. SAARC J. Agric., 19(2): 95-106 (2021)

株距×行距对两个水稻品种的影响

2017年11月至2018年4月，在孟加拉国农业大学Mymensingh进行了一项实地研究，以评估株距对两个Boro水稻品种产量和产量贡献性状的影响。选用BINA丹-10和BRRI丹- 28两个水稻品种，在25 cm × 15 cm、25 cm × 25 cm、30 cm × 30 cm、35 cm × 35 cm、40 cm × 40 cm 5个株距中进行随机完全区组设计，3个重复。品种和株距对生长性能、产量贡献性状和产量影响显著。在25 cm × 15 cm种植间距下，BINA - 10的籽粒产量最高(8.75t ha-1)，秸秆产量最高(11.56 t ha-1)，生物产量最高(20.31 t ha-1)，收获指数最高(43.05%)。在种植间距为40 cm × 40 cm时，BINA -10的总分蘖数为14.75个，有效分蘖数为12.87个。在此基础上，建议BINA -10在25 cm × 15 cm下种植，以获得最大的水稻产量。南盟J.农业浙江农业学报，19(2):95-106 (2021)
