Abstract
A field experiment was conducted during 2010 – 2011 and 2011–2012 seasons at the Experimental Farm, Department of Field Crop Science College of Agriculture University of Baghdad to study the effect of Boron and Vitamin C on some growth characteristics of wheat (var. Abu–Ghraib 3). Factorial experimental in RCBD with four replications was used. Treatments involved two factors , first was foliar application of boron in five concentrations 0, 100, 200, 300, 400 mg .L-1 the second was vitamin C foliar application in five concentrations 0, 1, 2,3,4, gmL-1. Results showed that higher concentration of boron 400 mg L-1 was superior in flag leaf area 43.02 cm2 , 41.59 cm2, number of total tillers m-2 were 680.9 tiller m-2 643.0 tiller m-2 for both seasons, dry weight 1983.5 gm-2, crop growth rate 16.80 gm m-2 d-1 for first season and spike length 12.815 cm for second season, compared to control which gave the least value which were 36.81 cm2, 36.06 cm2, 513 tiller m2, 528 tiller m2, 1534.2 gm m2, 13.001 gm m-2d-1 and 11.852 cm. Boron applied in 300 mg B L-1 was superior in plant length about 99.62 cm , 101.04 cm and dry weight about 2217.0 gm m-2 crop growth rate, 17.185 gm m-2 d-1 for second season. Vitamin C concentration 4 gm L-1 was superior in plant length leaf area , number of total tillers m-2 dry weight, crop growth rate, spike length increasing with% increase of (2.78, 4.461%) (26.513, 21.370%) (12.767, 17.541%) (11.67, 18. 38%), (11.668, 18.390%) and (6.05, 4.13%) respectively, compared to control. The conclusion from this study was boron foliar applied 300,400 mg L-1 affected significantly most of studied characteristics of wheat while vitamin C affected significantly all growth characteristics, so we recommended 300 mgB L-1 and 4 gm L-1 vitamin C.
