EFFECT OF SPACING AND NUMBER OF SEEDLINGS HILL-1 ON THE YIELD OF BRRI dhan29 (Pages : 7 - 10)

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from November 2011 to July 2012 to study the effect of spacing and number of seedlings hill-1 on the yield of BRRI dhan29. Three spacings viz. 20 cm × 15 cm, 20 cm × 20 cm, 20 cm × 25 cm and three numbers of seedlings hill-1 viz. 2, 3 and 4 seedlings hill-1 were included as experimental treatment. The experiment was carried out in a randomized complete block design with four replications. The effect of spacing showed significant variation in respect of plant height, total tillers hill-1, number of effective tillers hill-1, number of non-effective tillers hill-1, panicle length, grains panicle-1, sterile spikelets panicle-1, grain yield, straw yield, biological yield and harvest index. The highest plant height (97.69 cm), the number of total tillers hill-1 (17.45), effective tillers hill-1 (13.41) and grains panicle-1 (158.15) were found with 20 cm × 25 cm spacing. The highest panicle length (23.94 cm) was obtained from 20 cm × 15 cm spacing. The highest grain yield of 5.02 t ha-1 was also obtained from the spacing 20 cm × 25 cm. Number of seedlings hill-1 showed significant effect on all the parameters except 1000-grain weight. The highest grain yield of 5.03 t ha-1 was obtained from 4 seedlings hill-1 while the lowest grain yield of 3.43 t ha-1 was found from 2 seedlings hill-1. The highest grain yield of 5.61 t ha-1 was obtained from interaction between 20 cm x 25 cm spacing with 4 seedlings hill-1 while the lowest grain yield of 2.51 t ha-1 were found from the interaction between 20 cm x 15 cm spacing with 2 seedlings hill-1. Results of the present study reveals that 20 cm x 25 cm spacing with 4 seedlings hill-1 was found to be the best for obtaining maximum grain yield of BRRI dhan29.Download
