Abstract
This research was conducted during spring and fall seasons, 2015 , at the fields of Field Crop Department – College of Agriculture –University of Baghdad. The objective was to study grain yield and yield components of corn in next generation as influenced by harvesting moisture in the first generation . In spring season 2015 , seeds of the variety 2018 was planted using 75 cm between rows and 25 cm within the rows. When moisture of the ear grains reach the first treatment (37-42%), ten ears were harvested. Ear harvesting dates were performed manually when the grains had 37-42%, 34-36% , 30-33% , 25- 28% and 19-22% moisture content. Then, the grains were naturally dried to 15.5 %. In fall season 2015 , varietal trail was carried out with the five treatment materials , using Randomized Complete Bock Design , with four replicates . The results revealed significant differences among treatments for all the studied traits . The highest number of grains (614 grains ear-1) and (4224 grains m-2), were produced from plants grown from seeds with (25-28)%, which significantly differs from other treatments . The highest grain weight ( 266 mg), grain yield (159.46 g.plant-1) and ( 10.70 t.ha-1) , were produced from the plants at the moisture content (19-22)% . It could be conclude , that the suitable corn grain moisture harvest for production seeds for next generation are (19-22)% .
Highlights
An option for early harvest is harvesting gains from the ear, without removing the peel and cob
Studies have shown that the maximum values of germination and vigor can occur when grains have high moisture content, even before they have reached physiological maturity [4,5]
Ear harvesting dates were performed manually when the grains had 37-42%, 34-36%, 30-33%, 2528% and 19-22% moisture content, ten ears were harvested for each treatment
Summary
