Abstract
Abstract A field experiment was conducted to study the response of bread wheat crop to indol-3-acetic acid (IAA) at variants growth stages during 2017-2018 at agronomy research farm, College of Agriculture, University of AL.qasim Green, Babylon-Iraq. Using Randomized Complete Bock Dazine(RCBD) with split plot arrangement. Man plot contained four concentration of 0, 50, 100 and 150 ppm of plant growth regulator (IAA), while sub plot consisted of three critical growth stages of namely S1(tillering. ZGS:21) S2(booting. ZGS:45) S3(flowering. ZGS:69). The data was recorded on pant height (cm) at maturity, flag leaf area(cm 2 ), chlorophyll content (SPAD), spike length (cm), number of spike/m 2 , number of grain/spike, 1000-grain weight (g), grain yield (t/ha −1 ), biological yield (t/ha −1 ). The results showed that IAA at the concentration 100 ppm produced maximum plant height (92.36cm), chlorophyll content (51.04)SPAD, spike length (14.25 cm) number of spike/m 2 (365.3), 1000-grain weight (36.50g), grain yield (6.61 t/ha −1 ).The application of IAA 100 ppm at the stage of booting gave maximum flag leaf area(47.66cm 2 ), chlorophyll content(54.66) SPAD, spike length(14.96 cm), 1000-grain weight(37.79g), grain yield(7.12 t/ha −1 ), biological yield(16.13 t/ha −1 ).
