Drum culture technique is used to determine water requirement of lowland rice. In this method, four drum of size 50×50×50 cm are taken i.e. A, B, C and D. A and B have bottom while C and D are without bottom. All the drums are embedded in soil leaving 20 cm above soil surface. Rice is transplanted in drum A, C & D. and rice seedlings without roots are planted in drum B and the data on percolation, evaporation, ET, transpiration and effective rainfall is obtained.
√1295.98 × √2704 ÷ 899.97 + 1915.375 = ?
14.232 + 19.98% of 629.99 = ? × 6.99
? = 41.92% of 49.96% of (45.07 1.97 – 4.98 2.03 )
20.02% of (95.96 × 104.01 – 56.02 × 64.04) – ? = 12.02 × 39.96 + 103.03
13.99% of 299.99 ÷ 7.17 = ? ÷ 16.15
72.8% of (215.69 + 189.38) - 5.97² + (3.01 of 7.8) = ? of (64.02 - 38.95)
√2023.85 + (24.77% of 1999.73) - (3/8 of 799.91) = ?
(8.083.03 + 59.59% of 839.83) ÷ 16.06 × 24.04 = ?3 + 1012.12
(29.97%) of 9840 + ? + (45.17% of 1240) = (31.99% of 11750)
