FAQ — પ. પ. જ. ગ.
Groundnut water requirement per Vigha Gujarat?
Groundnut total ET: 450mm/season. Per Vigha (1618.6 m²): 450mm × 1618.6 = 728,370 litres = 728 m³ net. With drip (90% eff): 809 m³ gross. 6-8 irrigations at 60-75mm each. Critical: pegging stage (60-70 DAP).
Cotton irrigation schedule Gujarat?
Cotton ET: 700mm, 9-12 irrigations. Sandy loam soil: irrigate every 7-10 days. Critical: flowering and boll development stages. Stop irrigation 3 weeks before first picking in October.
Wheat 6 irrigations Gujarat?
Wheat needs 6 irrigations at: CRI (21 DAP), tillering (45 DAP), jointing (65 DAP), booting (85 DAP), heading (95 DAP), dough stage (105 DAP). Total ET: 380mm. Most critical: CRI and booting.
Drip irrigation water saving vs flood?
Drip: 90% efficiency. Flood: 55% efficiency. For same crop: drip needs 39% less water. Groundnut 5V: Drip = 4,045 m³ vs Flood = 6,617 m³. Annual saving: 2,572 m³ = ₹1,854 electricity saved.
What is Kc (Crop Coefficient)?
Kc = Crop Coefficient from FAO-56. It shows water need relative to reference ET (ETo). Kc 0.35 = initial stage (low), Kc 1.20 = peak mid-season (maximum). Water needed = ETo × Kc × area.
