Foliar Application of Urea and Magic Growth Liquid Fertilizer on the Yield and Nutrient Content of Aman Rice Cultivars

摘要

The experiment was undertaken at the farm of Sher-e-Bangla Agricultural University, Dhaka-1207during the Aman season from July to December, 2013 to find out the effect of foliar application of urea alongwith magic growth spray on the yield and nutrient content of two Aman rice cultivars. The two factorialexperiments were laid out in a RCBD design with three replications. Two rice varieties viz., Bina-sail (V1), BRRIdhan46 (V2) and eight different nitrogen doses and application methods i.e. T0=N0 (No nitrogen applied),T1=N00+10% (Urea was applied only 10% of the recommended dose (RD) with magic growth as foliar spray),T2=N50+5% (50% Urea was applied as top dressing and 5% Urea was applied with magic growth as foliar spray),T3=N50+10% (50% Urea was applied as top dressing and 10% Urea was applied with magic growth as foliar spray),T4=N75+5% (75% Urea was applied as top dressing and 5% Urea was applied with magic growth as foliar spray),T5=N75+10% (75% Urea was applied as top dressing and 10% Urea was applied with magic growth as foliar spray),T6=N100 (100% of RD of Urea was applied as topdressing), T7=N100+10% (100% Urea was applied as top dressingand 10% Urea was applied with magic growth as foliar spray) were used in this experiment. BRRI dhan46 and75% Urea top dressing and 10% Urea with magic growth as foliar spray gave the highest number of effectivetillers hill 1, longer panicle, number of total grains panicle 1, 1000-grain weight, grain yield, straw yield and N,P, K content in rice grain. Moreover, 75% Urea top dressing and 10% Urea of the recommended dose with magicgrowth as foliar spray increased 8.27% grain yield with a saving of 15% of the recommended nitrogen fertilizercompared to recommended practice.
