Title

LEAF CLIPPING EFFECT ON YIELD AND YIELD COMPONENT OF THREE SEED CORN VARIETIES

Pages

  44-51

Abstract

 In order to study the effects of leaf clipping on YIELD and YIELD component of three seed CORN varieties a field experiment was conducted as factorial laid out in complete block design with three replications in 2005. Three varieties (700, 604 and 301) and four LEAF DEFOLIATION levels (without defoliation, ear leaf clipping. Above ear leaf clipping, and below ear leaf clipping) were used in this experiment. The result showed that defoliation, varieties and their interaction significantly affected on ear length, seed abortion, ear seed row number and grain YIELD. Varieties had different seed number in row and also defoliation affected on it. 1000-grian weight was not affected by any of defoliation treatments. On the whole, without defoliation, ear leaf clipping, and below ear leaf clipping treatments had the same ear length. Above ear leaf clipping reduced ear length. Ear length reduction, seed abortion, seed number in row, and grain YIELD was observed in 700, 604 and 301 in descending order respectively. The most ear seed row number, seed number per row and grain YIELD was obtained from without defoliation treatment. Ear and below ear leaf clipping was rank in second order in aspect of three former traits. Above ear leaf clipping produced the lowest ear seed row number, seed number in row and grain YIELD. Below ear leaf clipping and without defoliation produced the same grain YIELD in early maturity variety, but grain YIELD was more in without leaf clipping than other treatments in medium and late maturity variety. Response of early maturity variety to leaf clipping was severely more than late maturity variety (700). Low and non-significant effects of below ear leaf clipping on CORN grain YIELD show that medium and early maturity varieties can be cultivated in higher density than 7plant/m2. These two former varieties also can be used in intercropping (with legumes).
