Question
What is the most appropriate time to irrigate wheat if
only one irrigation is available during its growth period?Solution
Crown root initiation (CRI) is the most critical stage for wheat irrigation (around 21 DAS). Water at this stage supports root development, tillering, and subsequent growth stages.
(a – 2) 2 + (b + 6) 2 + (c – 1) 2 = 0, then find the value of a + b – c.
Length of each side of a rhombus is 13 cm and one of the diagonal is 24 cm. What is the area (in cm2) of the rhombus?

If (x 2 = 6x – 9), then find the value of [x³ + (x⁴/9)][5 - x³]
If [x + (1/x)] = 3, find [x2 + (1/x2)].
If x + y = 12 and x² + y² = 74, find xy.
If a3 + b3 = 6240 and a + b = 30, then find the value of {(a + b)2 – 3ab}
- If x² - 2x + 1 = 0, then find the value of (x² + x⁻²)(x³ + x⁻³).
(x + 4) 2 + (y – 1) 2 + (z + 2) 2 = 0, then find the value of 2x - 3y + z.
If x = 19, then the value of x5 - 20x4 + 20x3 - 20x2 + 20x - 1 is
