Influence of Irrigation Scheduling on Crop Growth Yield and Quality of Wheat
Abstract
A field experiment was carried out at Agronomy Farm, Anand Agricultural University, Anand during rabi season in 2011-2012. The treatment comprised of five levels of irrigation schedule Viz., I1 (CRI, TL, BT, FL, ML, SD), I2 (0.4 IW: CPE ratio), I3 (0.6 IW: CPE ratio), I4 (0.8 IW: CPE ratio) and I5 (1.0 IW: CPE ratio) in RBD within four replications. The growth attributes such as plant height (cm) and number of spike/ear were found significantly higher under I1 (CRI, TL, BT, FL, ML, DS) treatment. The total number of tiller/plant, grain weight/ear (cm), ear length (cm), harvest index (%) and test weight (g) were found higher under I1 (CRI, TL, BT, FL, ML, DS) and I4 (0.8 IW: CPE ratio) treatment. The highest grain yield and straw yield (4380 & 4538 kg /ha) was recorded under I1 treatment followed by I4 and I5 treatment. However the lowest grain and straw yield (3600 kg/ha) (4025 kg/ha) was recorded under I2 (0.4 IW: CPE ratio) treatment. It is concluded that application of water at CRI, TL, BT, FL, ML and DS is more economic for wheat than other tested water management treatment.References
