Abstract :
To evaluate the effect of foliar application of BA on morphological and physiological characteristics l Maize (Zea mays Var T.W.C.647) under cut irrigation, the experiment was conducted split plot in randomized complete block design with three replications at a farm in PAKDASHT at Tehran zone. Experimental treatments include main plots: C0 = Normal irrigation, C1= cut irrigation at stem elongation stage, C2 = cut irrigation at flowering stage, C3=cut irrigation at filling grain stage and sub plots of research include: M0= control (no application), M1 = 100 ppm, M2 = 200 ppm respectively. The results of this study showed that cut irrigation can reduce grain yield, grain weight, biological yield, harvest index, protein yield, oil content, oil yield, chlorophyll a and chlorophyll b, relative water content, but foliar application BA were increased the following parameters. The highest T.G.W, G.Y, B.Y, oil percentage and Total chlorophyll a were achieved Normal Irrigation * 200 ppm BA(341.1 gr, 8982.7 (Kg.ha), 28942.2(Kg.ha), 6.97(%),1.94 Spad) had no significant difference with C0M0,C0M2,C1M2. Therefore, it is recommended to use foliar application of BA with a concentration of 200 ppm in case of cut irrigation.
