| dc.description.abstract | An experiment was performed at Research Farm of Crop Physiology and Ecology
Department, Hajee Mohammad Danesh Science and Technology University,
Dinajpur, Bangladesh during T. Aman season (September to December) of 2018
to know the effect of integrated nutrient management on the growth and yield of
rice. It was replicated in thrice with Randomized Complete Block Design (RCBD)
and it was a single factor experiment. In this experiment, BRRI dhan51 used as
planting materials that was imposed with eight integrated nutrient management
treatments such as- T1- No fertilizer, T2-100% NPK, T3- 50% NPK+ 4 ton
cowdung ha-1
, T4- 50% NPK+ 8 ton cowdung ha-1
, T5- 50% NPK+ 12 ton
cowdung ha-1
, T6- 75% NPK+ 4 ton cowdung ha-1
, T7- 75% NPK+ 8 ton cowdung
ha-1
and T8- 75% NPK+ 12 ton cowdung ha-1
). At 30, 50, 70 and 110 DAT, the
tallest plant (60.85, 68.35, 80.35 and 95.69 cm) and greater number of leaves hill1
(80.34, 75.51, 70.65 and 62.34 cm) was found in T8 and the lowest was observed
in T1 in all aspects. The maximum total tillers hill-1
(23.01), productive tillers hill-1
(22.01), the longest panicle (29.67 cm), spiklets per panicle (242.09), grains per
panicle (225.02), Thousand grain weight (31.35 g), grain yield (5.05 t ha-1
), straw
yield ( 9.26 t ha-1
) and biological yield (14.31 t ha-1
) and minimum non-productive
tillers hill-1
(1.00) and sterile spiklets per panicle (12.07) were recorded in T8
which is statistical similar with T7 in most of the parameters. It is obvious that
yield of rice can be increased substantially with the judicious application of
organic manure and chemical fertilizers. | en_US |
