Effects of BAFoliar application on some qulity and quantity characteristics in hybrid Corn (Zea maysVar T.W.C.647) under cut irrigation in Pakdasht region.
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.
