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 in PAKDASHT. Experimental treatments include main plot: C0 = Normal irrigation, C1= cut irrigation at stem elongation stage, C2 = cut irrigation in flowering stage, C3=cut irrigation at filling grain stage and sub plot research include: = M0= control (no application) = M1 = 100 ppm. M2 = 200 ppm respectively. The results of this study showed that cutirrigation can reduce grain yield, grain weight, biological yield, harvest index, protein yield, oil content, oil yield, chlorophyll a and chlorophyll b, relative water content, was foliar application BA the following parameters were increased. The highest T.G.W, G.Y, B.Y, oil percentage and Chol a were achieved Normal Irrigation * 200 ppm AB (341.1 gr, 8982.7 (Kg.ha), 28942.2(Kg.ha), 6.97(%),1.94 Spad) had no significant difference with C0M0,C0M2,C1M2
