Abstract:

A field experiment was conducted to identify a critical crop growth stage susceptible to artificial lodging leading to yield loss and yield structure modification in dicoccum wheat variety ‘Mudhol local’ during rabi seasons of 2009 and 2010 at Agricultural Research Station, Madhurakhandi, UAS Dharwad, Karnataka. The experiment was laid out in a split plot design with main plot having two degrees of artificial lodging (45o and 900) and sub-plots imposed with artificial lodging at four feekes growth stages (FS 10.3, FS 10.52, FS 11.3 and FS 11.52) and a control (without artificial lodging) and the treatment combinations were replicated thrice. Between degrees of artificial lodging, 450 recorded significantly higher grain yield of 1987 kg ha-1 compared to 900 (1796 kg ha-1). Among different stages of lodging, before-heading stage being on par with non-lodged conventional treatment (2082 kg ha-1) produced significantly higher grain yield (2201 kg ha-1). Lodging at mealy-ripe stage resulted in significantly lower grain yield of 1681 kg
ha-1. Interactions between degrees of lodging and stages of lodging showed that the grain yield with 450 compared to 900 artificial lodging was significantly higher at before-heading stage (2385 kg ha-1), at hard-kennel stage (1987 kg ha-1) and at mealy-ripe stage (1724 kg ha-1) and numerically higher at heading (2061 kg ha-1) and in conventional treatment (2082 kg ha-1).
